Two Spirit (Native LGBT) Communities说明书

A Spotlight onTwo Spirit (Native LGBT)CommunitiesOver the course of the past year, Two Spirit (Native LGBT)communities have garnered a great deal of attention withrespect to the status of their civil rights, health and personalsafety, employment opportunities, and more. This is asynthesis of current research reflecting their realities.The NCAI Policy Research Center wanted to highlight the status of Native LBGT and Two Spirit communities by sharing data and reports that show where we are gaining ground and where further support is needed. Please click the statistics & resources to be directed to their source. We hope these resources will be ofvalue to your work.Glossary:LGBT: Shorthand for lesbian, gay, bisexual, or transgender people.Two Spirit: Contemporary umbrella term that refers to the historical and current First Nations people whose individual spirits were a blend of female and male spirits. This term has been reclaimed by Native American LGBT communities in order to honor their heritage and provide an alternative to the Western labels of gay, lesbian, or transgender.CIVIL RIGHTS∙Recognizing our Two Spirit relatives:The NCAI passed a resolution at our 2015 Mid Year Conference in St. Paul titled, “Standing in Support of our Two Spirit Relatives in our Communities and Nations.”∙And supporting them in different venues—Native and non-Native: The Human Rights Campaign has been a strong ally and advocate for LGBT and Two Spirit Natives. They have collaborated with several Native leaders and advocates to share their stories here, here, and here.∙There are comprehensive resources available: The Two Spirit Resource Directory, which was updated this month, features community information on Two Spirit societies and groups in the United States and Canada, organizations, online resources, and Two Spirit films and books.∙Tribal nations can also access guidance: With the Tribal Equity Toolkit 2.0, tribal governments have access to examples of comprehensive resolutions and codes that support Two Spirit and LGBT justice in Indian Country.∙And many have made strides for marriage equality: With the Supreme Court striking down the Defense of Marriage Act, this year has brought attention to the legalization of same-sex marriage among states and tribes.The map below shows the extent to which marriage equality exists on tribal lands in the U.S.:Listed below are the 24 tribes whose laws now allow same-sex marriage within their jurisdictions (please notify us of additions or errors):-Coquille Tribe in Oregon (2009)-Mashantucket Pequot Tribe in Connecticut (2010)-Suquamish Tribe in Washington (2011)-Port Gamble S’Klallam Tribe in Washington (2011)-Little Traverse Bay Bands of Odawa Indians in Michigan (2013)-Pokagon Band of Potawatomi Indians in Michigan (2013)-Santa Ysabel Tribe in California (2013)-Confederated Tribes of the Colville Reservation in Washington (2013)-Cheyenne and Arapaho Tribes in Oklahoma (2013)-Leech Lake Band of Ojibwe in Minnesota (2013)-Grand Portage Band of Chippewa in Minnesota (2013)-Puyallup Tribe of Indians in Washington (2014)-Salt River Pima-Maricopa Indian Community in Arizona (2014)-Wind River Indian Reservation in Wyoming (2014)-Blackfeet Indian Reservation in Montana (2014)-San Carlos Apache Tribe in Arizona (2014)-Fort McDermitt Paiute and Shoshone Tribes in Oregon and Nevada (2014)-Fort McDowell Yavapai Community in Arizona (2014)-Lac du Flambeau Band of Lake Superior Chippewa in Wisconsin (2014)-Pascua Yaqui Tribe in Arizona (2014)-Central Council of Tlingit and Haida Indian Tribes in Alaska (2015)-Oneida Nation in Wisconsin (2015)-Keweenaw Bay Indian Community in Michigan (2015)-Confederated Tribes of Siletz Indians in Oregon (2015)ECONOMIC OPPORTUNITY∙Many transgender Natives are facing workplace discrimination:36 percent of Native American transgender respondents reported losing a job because they are transgender (Center for American Progress and Movement Advancement Project, 2015, p. 10).∙Even when employment is maintained, it is far less likely to be full-time: In a state survey of LGBT and Two Spirit people, American Indians reported the lowest rate of full‐time employment at 37 percent (Frazer and Pruden, 2010, p.5).∙And these trends affect household incomes and the ability for same-sex couples to provide for their families: A 2008 national survey of transgender and gender-nonconforming people revealed that 23 percent of AI/ANs were in extreme poverty—earning less than $10,000 per year (Harrison-Quintana et al., 2012, p. 1). More than 1 in 3 children (35.2 percent) being raised by Native same-sex couples are living below the federal poverty level (Albelda et al., 2009, p. 13).∙So much so, that it is hard to put food on their tables: More than half of LGBT Native Americans(55 percent) are food insecure—having limited or uncertain availability of nutritionally adequate andsafe foods (Gates, 2014, p. 2).∙Fortunately, some federal programs provide equal access to LGBT families: SNAP, WIC, and School Lunch programs do not narrowly define “families”or require that applicants for these services be related legally or by blood (Center for American Progress, Movement Advancement Project, and Family Equality Council, 2011, p. 4).FAMILY ACCEPTANCE∙Family acceptance is essential to the well-being of LGBT children: research shows that family acceptance promotes well-being and helps protect LGBT young people against risk, while family rejection has a serious impact on a gay or transgender young person’s risk for health and mental health problems. Family rejection includes trying to change a child’s orientation. While some parents consider this a caring reaction, gay children experience these behaviors as rejection and can cause LGBT youth to feel like they have to hide who they are.∙Families want to help LGBT youth, but often don’t know how. While some parents are trying to protect their children from harm, they can put a child at very high risk for suicide, depression and other health problems. Some types of rejecting behaviors, like blocking access to gay friends and resources or preventing a child from attending family events, are just as harmful as physically beating a gay or transgender child (Family Acceptance Project, 2009, p. 8).∙Risks from rejection are severe: LGBT young adults who reported high levels of family rejection during adolescence were: more than 8 times more likely to have attempted suicide; about 6 times more likely to report high levels of depression; more than 3 times more likely to use illegal drugs compared with peers from families that reported no or low levels of family rejection. (Ryan et al, 2009)Source: Family Acceptance Project, 2009∙Families love their LGBT children, but sometimes must learn how to protect and support LGBT children: When parents and family communicate that they value and love their LGBT child, children also learn to value themselves.Source: Family Acceptance Project, 2009∙More resources: Supportive Families, Healthy Children: Helping Families with Lesbian, Gay, Bisexual & Transgender Children by Caitlin Ryan, Family Acceptance Project, San Francisco State University, 2009.HEALTH STATUS AND SUICIDE RISK∙Culturally-appropriate health education and services are critical: Native gay and Two Spirit men are at higher risk for HIV transmission and infection. In 2013, 71 percent of new HIV diagnoses (120 of 169) among AI/AN men were attributed to homosexual (M2M) contact (CDC, 2015).∙As is building resilience in the face of suicidal risk: 56 percent of Native transgender and gender nonconforming respondents in a national survey had attempted suicide, as compared with 41 percent of all other transgender groups (Harrison-Quintana et al., 2012, p. 1).∙But being rooted in one’s identity heals: Research has revealed that urban LGBT and Two Spirit Natives’ experiences of discrimination decreases their self-rated health and increases self-reported physical pain and impairment. However, this trend was diminished if the individual felt high levels of actualization, which is positive integration between self-identity and racial group identity (Chae and Walters, 2009).∙That’s why we need to s upport more conversations internally: This year, both NCAI and the United National Tribal Youth (UNITY) hosted some of their first-ever dialogues on Two Spirit and LGBT identity and issues. Find resources here and here.∙As well as policy conversations at the federal level: In 2013, SAMHSA issued new guidance concerning standards of care for lesbian, gay, bisexual, transgender, questioning, intersex, and Two Spirit AI/AN youth. SAMHSA has also published several online resources through its Tribal Training and Technical Assistance Center Two Spirit Learning Community. And in July 2015, the Indian Health Service hosted a listening session on LGBT Native health issues.SAFETY AND SHELTER∙Many LGBT and Two Spirit Natives struggle to find safety: In one state survey, nearly 1 in 3 LGBT Natives (29.4 percent) reported experiencing hate violence—a higher rate than any other LGBT group (Frazer and Pruden, 2010, p.10). Research with Native lesbian, bisexual, and Two Spirit women revealed high prevalence of both sexual (85 percent) and physical (78 percent) assault (Lehavot et al., 2009).∙Too frequently, schools are venues for violence against youth: 54 percent of Native gay or lesbian students experience physical violence because of their sexual orientation (Diaz and Kosciw, 2009, p.13) and more than 1 in 3reported missing class at least one month for fear of being bullied orharassed (Center for American Progress and Movement Advancement Project, 2015, p. 25).∙And safe homes may also be hard to find: It is estimated that between 20 and 40 percent of youth experiencing homelessness identify as LGBT, questioning, intersex, or Two Spirit. 26 percent ofLGBT youth were forced from their home upon revealing their sexual identity to their parents (Ray et al., 2006, p. 11-14; 4).∙For transgender Natives, housing discrimination is not uncommon: 47 percent of AI/ANs have been denied a home or apartment because they were transgender or gender non-conforming (Grant et al., 2011, p. 113).∙However, there has been some movement to eradicate these trends: SAMHSA hosted a Listening Tour in 2010 and produced a report with promising practices for supporting homeless LGBT youth.In June 2015, the Obama Administration and HUD announced plans to roll out new housing protections for LGBT Natives on tribal lands.DATA RECOMMENDATIONS∙Improving research and science:The Williams Institute at the UCLA School of Law published a “Best Practices for Asking Questions about Sexual Orientation on Surveys” report in 2009. We encourage our partners engaged in collecting tribal data that includes sexual minorities to consult this guide for detailed recommendations.∙Recommendations for the Indian Health Service: Representatives from the NCAI and its Policy Research Center attended the IHS listening session and presented recommendations for improving: cultural competency with AI/AN LGBT individuals; measures of culturally relevant services; data collection measures; intake processes; LGBT health education; referrals; among other areas.*If you have further resources to share, please email*****************.。

Apache日志格式

Apache⽇志格式apache中⽇志记录格式主要有两种，普通型（common）和复合型（combined），安装时默认使⽤普通型（common）类型⽇志记录访问信息，LogFormat指令：定义格式并为格式指定⼀个名字，以后我们就可以直接引⽤这个名字CustomLog指令：设置⽇志⽂件，并指明⽇志⽂件所⽤的格式（通常通过格式的名字）ErrorLog指令：错误⽇志的位置可以通过ErrorLog指令设置：ErrorLog logs/error.log # 错误⽇志⽆论在格式上还是在内容上都和访问⽇志不同主配置⽂件⾥提供了两种⽇志的模板：common和combined<IfModule log_config_module>## The following directives define some format nicknames for use with# a CustomLog directive (see below).#LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combinedLogFormat "%h %l %u %t \"%r\" %>s %b" common<IfModule logio_module># You need to enable mod_logio.c to use %I and %OLogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio</IfModule>## The location and format of the access logfile (Common Logfile Format).# If you do not define any access logfiles within a <VirtualHost># container, they will be logged here. Contrariwise, if you *do*# define per-<VirtualHost> access logfiles, transactions will be# logged therein and *not* in this file.## 主配置⽂件⾥预设⽇志模板是commonCustomLog "logs/access_log" common## If you prefer a logfile with access, agent, and referer information# (Combined Logfile Format) you can use the following directive.##CustomLog "logs/access_log" combined</IfModule>默认格式common记录样例如下：192.168.1.1 - - [17/Mar/2022:20:09:47 +0800] "GET /img/horse.ico HTTP/1.1" 200 4286192.168.1.1 - - [17/Mar/2022:20:09:52 +0800] "GET / HTTP/1.1" 304 -1.远程主机IP2.空⽩(E-mail)3.空⽩(登录名)4.请求时间5.⽅法+资源+协议如：GET index.html HTTP/1.16.HTTP状态代码7.发送字节数：表⽰发送给客户端的总字节数log_config_module请求本⾝的情况将通过在格式字符串中放置各种"%"转义符的⽅法来记录，它们在写⼊⽇志⽂件时，根据下表的定义进⾏转换：%a 远端IP地址%A 本机IP地址%B 除HTTP头以外传送的字节数%b 以CLF格式显⽰的除HTTP头以外传送的字节数，也就是当没有字节传送时显⽰’-'⽽不是0。

例如字符串验证、电子邮件验证、IP地址验证等。

这些工具类中的方法都是静态的，可以直接通过类名调用，无需创建对象实例。

使用这些工具类可以大大简化代码，提高开发效率。

apache日志轮询设置讲解

Apache日志轮询使用cronolog和webalizer分割和分析apache日志web服务器的日志对于网站管理者来说有非常重要的作用，对于分析网站的访问情况、搜索引擎的抓取、图片盗链、非法抓取等有很大的帮助。

目前apache是最为广泛应用的web服务器，apache的日志功能能通过访问日志可以比较详细的记录网站服务器的被请求情况，但是要更好的根据日志来维护和管理网站则需要其他的工具来分析日志，以生成便于查看的报表。

默认安装的apache在运行时会产生两个日志文件，access_log用于存放访问记录，error则存放出错记录。

日志的生成格式可以定制的，需要在配置文件中定义LogFormat "%h %l %u %t \"%r\" %>s %b" commonCustomLog logs/access_log common上面的配置是最常用的一种记录格式，产生的日志格式如下：127.0.0.1 - - [02/Jan/2007:19:41:07 +0800] "GET /themes/original/img/s_error.png HTTP/1.1" 200 272这是一条典型的apache访问记录，这条记录里面包含有远程访问IP( 127.0.0.1 )、访问者身份（现在一般缺省，以-代替）、访问者标识（缺省以-代替）、请求时间(02/Jan/2007:19:41:07 +0800)、请求方式(GET)、请求的协议(HTTP/1.1)、请求的资源(/themes/original/img/s_error.png)、响应情况(200，代表成功)、传输的字节数(272)。

还有一种比较常用的格式LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined CustomLog log/access_log combined127.0.0.1 - - [02/Jan/2007:19:41:07 +0800] "GET /themes/original/img/s_error.png HTTP/1.1" 200 272"" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20061208 Firefox/2.0.0.1"Referer标示记录下来源，User-Agent则会记录客户端浏览器提供的一些识别信息，比如操作系统类别、浏览器类型和版本等，当然也可能是爬虫的信息。

Apache 日志配置及查看方法

Apache 日志配置及查看方法有时候我们需要定制Apache默认日志的格式和内容，比如增加或减少日志所记录的信息、改变默认日志文件的格式等。

本文介绍可以用日志记录的所有信息，以及如何设置Apache 使其记录这些信息。

一、定义日志格式很久以前，日志文件只有一种格式，这就是“公共格式”，许多人已经习惯于使用这种格式。

随后出现了定制日志格式，而且看起来定制日志格式更很受欢迎，即使公共日志格式本身也重新用定制日志格式定义。

本文介绍的就是如何随心所欲地定制日志文件的格式、如何让日志文件记录自己想要的信息。

定制日志文件的格式涉及到两个指令，即LogFormat指令和CustomLog指令，默认httpd.conf文件提供了关于这两个指令的几个示例。

LogFormat指令定义格式并为格式指定一个名字，以后我们就可以直接引用这个名字。

CustomLog指令设置日志文件，并指明日志文件所用的格式（通常通过格式的名字）。

LogFormat指令的功能是定义日志格式并为它指定一个名字。

例如，在默认的httpd.conf文件中，我们可以找到下面这行代码：LogFormat "%h %l %u %t \"%r\" %>s %b" common该指令创建了一种名为“common”的日志格式，日志的格式在双引号包围的内容中指定。

格式字符串中的每一个变量代表着一项特定的信息，这些信息按照格式串规定的次序写入到日志文件。

Apache文档已经给出了所有可用于格式串的变量及其含义，下面是其译文：%...a: 远程IP地址%...A: 本地IP地址%...B: 已发送的字节数，不包含HTTP头%...b: CLF格式的已发送字节数量，不包含HTTP头。

例如当没有发送数据时，写入‘-’而不是0。

%...{FOOBAR}e: 环境变量FOOBAR的内容%...f: 文件名字%...h: 远程主机%...H 请求的协议%...{Foobar}i: Foobar的内容，发送给服务器的请求的标头行。

Apache提示Youdonthavepermissiontoaccessonthisse。。。

Apache提⽰Youdonthavepermissiontoaccessonthisse。

昨天修改apache配置，不⼩⼼搞得报错：You don't have permission to access / on this server。

不得已，拿原始未经，从新修改了⼀遍，还是不⾏，⽹上都是⼀样的答案，改什么 <Directory> ，结果还是不可以，⽂件夹权限都777了依然不⾏.最后修改 httpd.conf中的 User 配置为当前登录⽤户才搞定。

4. User：设置实际提供服务的⼦进程的⽤户。

为了使⽤这个指令，服务器必须以root⾝份启动和初始化。

如果你以⾮root⾝份启动服务器，⼦进程将不能够切换⾄⾮特权⽤户，并继续以启动服务器的原始⽤户⾝份运⾏。

如果确实以root⽤户启动了服务器，那么⽗进程将仍然以root⾝份运⾏。

⽤于运⾏⼦进程的⽤户必须是⼀个没有特权的⽤户，这样才能保证⼦进程⽆权访问那些不想为外界所知的⽂件，同样的，该⽤户亦需没有执⾏那些不应当被外界执⾏的程序的权限。

强烈建议专门为Apache⼦进程建⽴⼀个单独的⽤户和组。

⼀些管理员使⽤nobody⽤户，但是这并不能总是符合要求，因为可能有其他程序也在使⽤这个⽤户。

例：User daemon
5. Group：设置提供服务的Apache⼦进程运⾏时的⽤户组。

为了使⽤这个指令，Apache必须以root初始化启动，否则在切换⽤户组时会失败，并继续以初始化启动时的⽤户组运⾏。

Apache中按天分割日志（Windows）

Apache中按天分割⽇志（Windows）⽹上很多资料都有对Apache的access.log按天⽣成的⽅法，但在Windows server下稍有不同：1、打开httpd.conf配置⽂件找到：CustomLog "logs/access.log" common2、将其改为：CustomLog "|bin/rotatelogs.exe logs/%Y_%m_%d.access.log 86400 480" common红⾊部分与⽹上⼤部分资料不同，windows下应使⽤相对路径，使⽤绝对路径Apache会启动会报错。

===========================================================================在apache的配置⽂件中找到ErrorLog logs/error_logCustomLog logs/access_log commonLinux系统配置⽅法：将其改为ErrorLog "| /usr/local/apache/bin/rotatelogs /home/logs/www/%Y_%m_%d_error_log 86400 480"CustomLog "| /usr/local/apache/bin/rotatelogs /home/logs/www/%Y_%m_%d_access_log 86400 480" commonWindows系统下配置⽅法：#ErrorLog "|bin/rotatelogs.exe logs/vicp_net_error-%y%m%d.log 86400 480"#CustomLog "|bin/rotatelogs.exe logs/vicp_net_access-%y%m%d.log 86400 480" common第⼀次不知道设置480这个参数，导致⽇志记录时间和服务器时间相差8⼩时，原来是rotatelogs有⼀个offset参数，表⽰相对于UTC的时差分钟数，中国是第⼋时区，相差480分钟。

APACHE II 评估工具-新

APACHE II 评估工具-新简介APACHE II（Acute ___）是一种常用于评估危重病患预后的工具。

它可以用来评估患者的生理情况、严重程度以及预测住院期间的病死率。

APACHE II评分系统通过对患者的生理数据进行评估，为医生提供了一个客观的指标来评估患者的危险程度和治疗效果。

使用方法APACHE II评估工具需要收集以下十一个变量的数据：1.年龄：患者的年龄（须以完整的岁数输入，精确到岁）。

2.性别：患者的性别，男性为1，女性为0.3.平均动脉压（MAP）：患者的平均动脉压（单位为mmHg）。

4.呼吸频率：患者的呼吸频率（单位为次/分钟）。

5.FiO2：患者的吸入氧浓度（单位为%）。

6.温度：患者的体温（单位为摄氏度）。

7.心率：患者的心率（单位为次/分钟）。

8.pH值：患者的动脉血pH值。

9.轻度意识障碍：患者是否存在轻度意识障碍，有则为1，无则为0.10.大手术/创伤：患者是否有大手术或创伤史，有则为1，无则为0.11.慢性病存在：患者是否存在慢性病，有则为1，无则为0.数据收集完成后，根据各个变量的值，可以根据APACHE II评分系统的公式计算出患者的APACHE II得分。

APACHE II得分越高，说明患者的危险程度越高。

评估结果APACHE II评估工具通过患者的生理数据为医生提供了一个综合的评估结果，包括以下三个方面的信息：1.预测病死率（%）：通过APACHE II得分可以估计出患者住院期间的病死率。

2.危险程度：APACHE II得分越高，说明患者的危险程度越高。

3.预后情况：APACHE II得分可以作为评估患者预后情况的参考指标，有助于制定治疗方案和预测患者的疗效。

需要注意的是，APACHE II评估工具只是一个辅助诊断和评估工具，结果需要结合临床医生的专业判断来综合评估患者的状况和制定治疗计划。

总结APACHE II评估工具是一种常用的危重病患预后评估工具，通过对患者的生理数据进行评估，提供了一个客观的指标来评估患者的危险程度和预测住院期间的病死率。

apache doirs 联邦查询原理 -回复

apache doirs 联邦查询原理-回复Apache Doris（原Apache Incubator项目Palo）是一个基于开源的分布式列式存储的分析型数据库。

它使用类似于Google的Dremel系统的分布式查询引擎，可以处理大规模数据，并快速响应查询请求。

在本文中，我们将探讨Apache Doris的联邦查询原理，并逐步回答有关该主题的问题。

什么是联邦查询？联邦查询是指在分布式系统中，将多个数据源的数据集合在一起进行查询和分析的过程。

在Apache Doris中，它允许用户在不同的物理集群上执行查询，并将结果组合在一起返回给用户。

联邦查询的原理是什么？Apache Doris使用了一种称为分布式查询计划（Distributed Query Plan）的技术来实现联邦查询。

在执行联邦查询之前，系统会根据查询的条件和数据源情况生成一个查询计划。

下面是Apache Doris的联邦查询原理的一步一步解释：1. 生成查询计划：当用户提交一个联邦查询时，Apache Doris会将查询解析为查询计划。

查询计划包含了查询的各个步骤和所需的资源。

2. 配置数据源信息：Apache Doris需要知道每个数据源的位置和连接信息。

在联邦查询之前，管理员需要配置数据源的元数据和连接信息，并将其存储在系统的元数据存储中。

3. 数据分片：Apache Doris通过数据分片将数据划分为多个小部分，以便并行处理。

每个数据源都有自己的数据分片。

4. 选择执行节点：根据查询计划和数据分片的情况，Apache Doris会选择哪些执行节点负责执行查询。

执行节点是分布在不同物理集群上的计算资源。

5. 发送查询请求：执行节点根据查询计划和数据分片情况，将查询请求发送给相应的数据源。

6. 数据源执行查询：每个数据源会接收到来自执行节点的查询请求，并根据查询计划和数据分片，执行查询操作。

7. 合并数据：执行节点在接收到来自数据源的查询结果后，将结果进行合并，以便将它们组合在一起返回给用户。

Apache日志配置及查看方法

Apach‎e日志配置及‎查看方法有时候我们‎需要定制A‎p ache‎默认日志的‎格式和内容‎，比如增加或‎减少日志所‎记录的信息‎、改变默认日‎志文件的格‎式等。

本文介绍可‎以用日志记‎录的所有信‎息，以及如何设‎置Apac‎h e 使其记‎录这些信息‎。

一、定义日志格‎式很久以前，日志文件只‎有一种格式‎，这就是“公共格式”，许多人已经‎习惯于使用‎这种格式。

随后出现了‎定制日志格‎式，而且看起来‎定制日志格‎式更很受欢‎迎，即使公共日‎志格式本身‎也重新用定‎制日志格式‎定义。

本文介绍的‎就是如何随‎心所欲地定‎制日志文件‎的格式、如何让日志‎文件记录自‎己想要的信‎息。

定制日志文‎件的格式涉‎及到两个指‎令，即LogF‎o rmat‎指令和Cu‎s tomL‎o g指令，默认htt‎p d.conf文‎件提供了关‎于这两个指‎令的几个示‎例。

LogFo‎r mat指‎令定义格式‎并为格式指‎定一个名字‎，以后我们就‎可以直接引‎用这个名字‎。

Custo‎m Log指‎令设置日志‎文件，并指明日志‎文件所用的‎格式（通常通过格‎式的名字）。

LogFo‎r mat指‎令的功能是‎定义日志格‎式并为它指‎定一个名字‎。

例如，在默认的h‎t tpd.conf文‎件中，我们可以找‎到下面这行‎代码：LogFo‎r mat "%h %l %u %t \"%r\" %>s %b" commo‎n该指令创建‎了一种名为‎“commo‎n”的日志格式‎，日志的格式‎在双引号包‎围的内容中‎指定。

格式字符串‎中的每一个‎变量代表着‎一项特定的‎信息，这些信息按‎照格式串规‎定的次序写‎入到日志文‎件。

Apach‎e文档已经‎给出了所有‎可用于格式‎串的变量及‎其含义，下面是其译‎文：%...a: 远程IP地‎址%...A: 本地IP地‎址%...B: 已发送的字‎节数，不包含HT‎T P头%...b: CLF格式‎的已发送字‎节数量，不包含HT‎T P头。

apachedoris java使用实例

apachedoris java使用实例Apache Doris（原称Palo）是一个开源的实时联机分析处理（OLAP）引擎，它基于列式存储，提供高性能的数据查询和分析能力。

本文将介绍如何在Java中使用Apache Doris，以及提供一些使用实例。

首先，为了在Java中使用Apache Doris，我们需要将其相应的依赖项添加到项目中。

可以通过Maven或Gradle来管理依赖项，下面是一个使用Maven的示例：```xml<dependencies><dependency><groupId>org.apache.doris</groupId><artifactId>doris-client</artifactId><version>0.14</version></dependency></dependencies>```添加了依赖项后，我们可以开始使用Apache Doris提供的Java API。

下面是一个简单的示例，演示如何连接到Apache Doris集群，执行查询并获取结果：```javaimport java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.Statement;public class DorisExample {private static final String JDBC_DRIVER = "org.apache.doris.jdbc.Driver";private static final String DB_URL ="jdbc:doris://<doris_host>:<doris_port>/<database_name>";private static final String USER = "<username>";private static final String PASS = "<password>";public static void main(String[] args) {Connection conn = null;Statement stmt = null;try {Class.forName(JDBC_DRIVER);conn = DriverManager.getConnection(DB_URL, USER, PASS);stmt = conn.createStatement();String sql = "SELECT * FROM <table_name>";ResultSet rs = stmt.executeQuery(sql);while (rs.next()) {// 处理结果集}rs.close();} catch (Exception e) {e.printStackTrace();} finally {try {if (stmt != null) stmt.close();if (conn != null) conn.close();} catch (Exception e) {e.printStackTrace();}}}}```在上面的示例中，需要将`<doris_host>`替换为Apache Doris的主机名或IP地址，将`<doris_port>`替换为端口号，将`<database_name>`替换为要连接的数据库名称，将`<username>`和`<password>`替换为合适的凭据信息。
