Linux安装MySQL数据库(安装验证)
数据库Mysql安装1.首先下载安装包并使用命令tar解压：命令格式：tar -zxvf MySQL-version-OS.tar.gz我的操作: tar –zxvf mysql-5.1.30.tar.gz使用cd命令进入解压后的目录命令格式：cd MySQL-version-OS./configure 之前要make clean 一下吧,为什么,好像是防止原来编译过注释：在执行“make clean”失败时，提示错误checking for termcap functions library... configure: error: No curses/termcap library found 。
则在执行./configure命令，执行命令代码为:./configure --prefix=/usr/share/mysql/ -with-charset=utf8 -with-extra-charsets=all –with-named-curses-libs=/usr/lib/libncursesw.so.5(最后一段命令可以省略)出现错误：No curses/termcap library found 或者see the install manual chapter in the referenceyum –y install gcc yum install ncurses-devel2.配置和编译安装环境2.1配置安装环境命令格式：./configure –prefix=安装路径--prefix=/usr/local/mysql/ 安装到此目录下我的操作: ./configure --prefix=/usr/local/mysql/-with-charset=gbk -with-extra-charsets=all 加入解决中文乱码./configure --prefix=/usr/share/mysql/ -with-charset=gbk -with-extra-charsets=all参数: --prefix= 指软件安装的路径2.2编译安装环境命令格式：make执行make命令时出现错误：exec g++ not found安装gcc -c++重新执行上一命令(config)等待……….时间太长了2.3安装命令格式：make install3.创建MySQL相关用户使用命令groupadd创建用户组命令格式：groupadd mysql使用命令useradd创建用户并分配到mysql组中命令格式：useradd –g mysql mysql使用命令passwd修改用户密码命令格式：passwd mysql我的密码: password4.配置MySQL数据库环境4.1.使用命令cp拷贝示例配置文件到系统环境命令格式：此步骤在解压的目录cp ./support-files/f /etc/f拷贝目标文件f必须要这样命名，该名称为数据库默认配置文件。

RedHat Server7.1安装与配置从RHEL7开始，使用systemctl工具来管理服务程序，包括了service和chkconfig [root@rhel7 ~]# systemctl list-unit-files|grep enabled启动一个服务：systemctl start firewalld.service关闭一个服务：systemctl stop firewalld.service重启一个服务：systemctl restart firewalld.service显示一个服务的状态：systemctl status firewalld.service在开机时启用一个服务：systemctl enable firewalld.service在开机时禁用一个服务：systemctl disable firewalld.service查看服务是否开机启动：systemctl is-enabled firewalld.service;echo $?查看已启动的服务列表：systemctl list-unit-files|grep enabled一、安装通过iso文件进行安装，最小安装时，ifconfig等命令是不可使用的。
可以通过“ip link show”、“ip address”等命令查看IP地址。
（一）网卡的配置RedHat7对网卡的命名有了很大不同，可以参考如下命名规则：本人在虚拟机上安装RedHat Server7.1后，网卡被命名为enp0s3，网卡的配置文件为/etc/sysconfig/network-scripts/ifcfg-enp0s3。
因此IP地址、子网掩码、网关、dns等均可在这个文件中进行配置。
下图展示了一个配置文件：当前是static（静态IP地址），如果要使用dhcp，则修改：BOOTPROTO=dhcpONBOOT=yes #开启自动启用网络连接，如果设置为no，则启动系统后网卡不能链接IPADDR=172.28.14.220 #设置IP地址PREFIX=27 #设置子网掩码GATEWAY=172.28.14.193 #设置网关DNS1=222.172.220.68 #设置主DNSDNS2=xxx.xxx.xxx.xxx #设置备DNS完成后service network restart #重启网络（二）ssh启动#/bin/systemctl start sshd.service（三）添加用户#groupadd webmanager ‘添加管理网站的组‘添加用户名为：webmanager，属组：webmanage，密码：nts20080808，主目录：/home/website/#useradd webmanger -g webmanage –p nts20080808 -d /home/website/修改用户登录名：#usermod -l webmanager webmanger ‘将用户名webmanger修改为webmanager修改用户webmanger登录密码:#passwd webmanger（四）设置iso文件为本地安装源1.上传iso文件将radHat Server7的iso文件rhel-server-7.1-x86_64-dvd.iso上传到服务器的/home/website/download/iso目录下。

Note that developer kits may have an earlier revision of the module, in which case only INA monitors related to the carrier board are available.To monitor power consumption in software1.Verify the version of L4T is 24.2 or higher with the following command:head -1 /etc/nv_tegra_releaseIf the version of L4T is not at least 24.2, please download the latest JetPack installer from the Embedded Developer Zone website and update your Jetson TX1.2.Verify that the Jetson TX1 module is revision 300 or higher from the module SKU withthe following command:sudo i2cdump -y -r 0x14-0x26 2 0x50 bThe feature to enable use of INA monitors is added in revision 300 and later of Jetson TX1. For example, SKU 699-82180-1000-300 has the feature.3.Read the information from the INA3221 monitors via sysfs nodes. The namingconvention for sysfs nodes is given in the following table, where <N> is a channelnumber 0-2.Note: The INA driver may also present other nodes. Do notmodify any INA sysfs node value. Modifying these valuescould result in damage to your device.The Jetson TX1 module has a 3-channel INA3221 monitor at I2C address 0x40. The sysfs nodes to read for rail names, voltage, current, and power are in the following directory:/sys/devices/platform/7000c400.i2c/i2c-1/1-0040/iio_device/The rail names for I2C address 0x40 are described in the following table:The Jetson TX1 Developer Kit carrier board has 3-channel INA3221 monitors at I2C addresses 0x42 and 0x43. The sysfs nodes to read rail name, voltage, current & power can be found at:/sys/devices/platform/7000c400.i2c/i2c-1/1-0042/iio_device//sys/devices/platform/7000c400.i2c/i2c-1/1-0043/iio_device/These are the rail names for I2C address 0x42:These are the rail names for I2C address 0x43:Examples④To read INA3221 at 0x40, the channel-0 rail name (i.e., VDD_IN), use the followingcommand:cat /sys/devices/platform/7000c400.i2c/i2c-1/1-0040/iio_device/rail_name_0④To read VDD_IN voltage, current, and power, use the following commands:cat /sys/devices/platform/7000c400.i2c/i2c-1/1-0040/iio_device/in_current0_inputcat /sys/devices/platform/7000c400.i2c/i2c-1/1-0040/iio_device/in_voltage0_inputcat /sys/devices/platform/7000c400.i2c/i2c-1/1-0040/iio_device/in_power0_inputUse of this feature also has the following considerations:④The feature enabling use of INAs was not part of the original Jetson TX1 specification.Therefore, earlier modules are not subject to RMA or automatic exchange because they lack this feature. If you need to measure module INAs, purchase the latest module.④All production modules (i.e., bare modules purchased separately from a Developer Kit)are revision 400 or newer, and support use of INAs.④In terms of accuracy, common practice is to assume a 10% guard band when workingwith INAs.④For Ubuntu, the i2cdump program is part of the i2c-tools package. You can install itwith commands similar to the following:sudo add-apt-repository universesudo apt-get updatesudo apt-get install i2c-tools2.3HDMI Audio Devices in the Audio Settings ApplicationThe HDMI audio output device is not getting listed for some televisions and monitors including the following:④Samsung TV 1080p LA40M81BM/XTL④LG Flatron W2363D④Samsung UA21ES5000RLXL④LG 25UM65-pThe issue is inconsistent and sometimes occurs on subsequent reboots.To workaround④If the HDMI audio output device is not listed in audio settings, restart the pulseaudiodaemon by killing the running instance as a normal user with the following command: pulseaudio --killor register the systemd pulseaudio service to start the pulseaudio daemon at every login: systemctl --user enable pulseaudio.serviceNote:Do not run pulseaudio as a root user.2.4New Users Must be Added to Video GroupWhen adding users to the system you must add them to the video group for the Linux desktop to appear correctly and function correctly.2.5Symlinks May be Overwritten by Installation of ThirdParty LibrariesInstalling third party libraries on the target device may overwrite the accelerated library provided by Linux for Tegra.For example, installing Mesa EGL may create a /usr/lib/<arch>/libEGL.so symlink, overwriting the symlink to the implementation library that should be used instead,/usr/lib/<arch>/tegra-egl/libEGL.so.Linux for Tegra installs a boot-time initialization script /etc/init/nv.conf, that corrects typical occurrences, such as with OpenGL, EGL, and X11 GLX libraries. This script runs at boot and corrects typical occurrences.To workaroundReboot after installation of packages that install conflicting library symlinks.2.6GStreamer-0.10 Not IncludedGstreamer version 0.10 is not included in this release. Use of GStreamer version 1.0 is required for development.2.7Maximizing Tegra X1 PerformanceUse the jetson_clocks.sh script to maximize performance by disabling DVFS, CPU Idle, and CPU Quit. JetPack installer or the flashing script places the script in the home directory on the target at:$HOME/jetson_clocks.shOn the host system, the script is delivered in the TAR file at:Linux_for_Tegra/nv_tegra/nv_tools.tbz2For more information on power and performance management, see:/Jetson/PerformanceSample Script Usage1.Show the current (initial) settings with the following command:sudo ./jetson_clocks.sh --show2.Store the current settings with the following command:sudo ./jetson_clocks.sh --store3.Maximize Jetson TX1 performance with the following command:sudo ./jetson_clocks.sh4.Show the current settings with the following command:sudo ./jetson_clocks.sh --show5.Restore the previous settings with the following command:sudo ./jetson_clocks.sh --restore6.Show the current settings with the following command:sudo ./jetson_clocks.sh --show2.832-bit hardfp Support RemovedBeginning with L4T R24.2.1 release, all releases onward support aarch64.

1.实验要求：1）准备好ISO安装包，我的安装包：rhel-server-7.0-x86_64-dvd。
2.实验目的：2）掌握Linux7.0的基本安装方法。
3. 实验说明：1）在安装Linux7.0时，我们需要在虚拟机上面创建好一个空白虚拟机，虚拟机的C盘大小根据你自己的情况而定，给20G或者50G，都可以的，然后把ISO 指定好路径，虚拟机内存根据你自己电脑情况来给，如果你的电脑性能比较好的话，你可以给2G或者4G，等等，给的越高安装的速度就越快，但是要根据你电脑的情况而定的。
实验步骤：准备工作我们都做好了以后，开启虚拟机Linux7.0.Linux7.0已经启动了。
虚拟机正在读取ISO信息，正在加载。
我们选择中文，简体中文，或者选择English，只要你看的懂就可以了。
进入到这个界面点击-软件选择。
选择带GUI的服务器，这里是什么意思了，如果以前安装过Linux5.3，Linux6.3 的朋友都知道，这代表的是桌面的意思，如果你选择的是最小安装的话，你安装好了以后，就直接进入到命令行里面了，就没有桌面了，这个地方一定要注意。
更改好了以后，就保存，然后在进入安装位置，也就是该磁盘分区。
选择我要配置分区。
进入以后，就到这个页面了，点击下面那个加号，就会出现添加新挂载点。
这里我们需要分3个区，第一个/boot,第二个/（根分区）,第三个swap（交换分区）第一个/boot分区已经完成了，继续创建。
创建根分区。
创建swap交换分区。
全部创建完成了。
选择接受更改。
都已经准备好了以后，选择开始安装。
我们来配置ROOT密码。
配置密码需要配置8位以上的，而且需要复杂性高，在配置密码时加点或者符号。
密码创建成功，然后在创建用户。
和刚才一样，密码需要复杂性，然后就需要耐心等待了。
安装好了以后，就选择重启。
重启后就会进入到这个页面，点击进去，选择同意，然后出去后选择继续下一步。
下一步，这里的kdump是在系统崩溃、死锁或者死机的时候用来转储内存运行参数的一个工具和服务。
RedHat7 yum安装
由于Red Hat Enterprise Linux 7 的更新包只对注册的用户生效，所以需要自己手动更改成CentOS的更新包，CentOS几乎和RedHat是一样的，所以无需担心软件包是否可安装，下面是安装步骤。
1、首先查看redhat 7.0系统本身所安装的那些yum 软件包：[root@linuxidc ~]# rpm -qa | grep yumyum-utils-1.1.31-24.el7.noarchyum-langpacks-0.4.2-3.el7.noarchyum-metadata-parser-1.1.4-10.el7.x86_64yum-rhn-plugin-2.0.1-4.el7.noarchPackageKit-yum-0.8.9-11.el7.x86_64yum-3.4.3-118.el7.noarch2、卸载这些软件包；[root@linuxidc ~]# rpm -e yum-3.4.3-118.el7.noarch --nodeps[root@linuxidc ~]# rpm -e yum-utils-1.1.31-24.el7.noarch --nodeps[root@linuxidc ~]# rpm -e yum-rhn-plugin-2.0.1-4.el7.noarch --nodeps[root@linuxidc ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps[root@linuxidc ~]# rpm -e yum-langpacks-0.4.2-3.el7.noarch --nodeps[root@linuxidc ~]# rpm -e PackageKit-yum-0.8.9-11.el7.x86_64 --nodeps3、保证本机电脑能上网；[root@linuxidc ~]# ping PING (163.177.151.110) 56(84) bytes of data.bytes from 163.177.151.110: icmp_seq=1 ttl=49 time=13.1 msbytes from 163.177.151.110: icmp_seq=2 ttl=49 time=6.80 msbytes from 163.177.151.110: icmp_seq=3 ttl=49 time=6.77 ms^C--- ping statistics ---packets transmitted, 3 received, 0% packet loss, time 2007msrtt min/avg/max/mdev = 6.777/8.917/13.168/3.006 ms4、进入以下网站上面查看软件包的版本是否升级或者找到自己系统所对应的文件包版本更新；网易163网络源地址：/CentOS网络源地址：/centos/5、找到自己所需要的版本下载：wget /centos/7/os/x86_64/Packages/yum-3.4.3-150.el7.centos.noarch.rpmwget /centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm wget /centos/7/os/x86_64/Packages/yum-utils-1.1.31-40.el7.noarch.rpmwget /centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-40.el7.noarch.rpmwget /centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm6、查看下载完成结果；[root@linuxidc ~]# lsanaconda-ks.cfg yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpminitial-setup-ks.cfg yum-updateonboot-1.1.31-40.el7.noarch.rpmyum-3.4.3-150.el7.centos.noarch.rpm yum-utils-1.1.31-40.el7.noarch.rpmyum-metadata-parser-1.1.4-10.el7.x86_64.rpm7、安装软件包：[root@linuxidc ~]# rpm -ivh yum-*warning: yum-3.4.3-150.el7.centos.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY error: Failed dependencies:python-urlgrabber >= 3.10-8 is needed by yum-3.4.3-150.el7.centos.noarch这里出现了一个小问题~~~：安装的python-urlgrabber版本不符合您尝试安装的RPM的依赖关系，我目前没有能力解决这个问题的办法，后来想了一个折中的办法，FQ去一个国外的yum源网站下载上面这五个较低版本的安装包，在来安装就不会有问题了在这里附上链接各位可以FQ出去下载对应版本的rpm包链接：/不报错版本安装包：yum-3.4.3-132.el7.centos.0.1.noarch.rpmyum-metadata-parser-1.1.4-10.el7.x86_64.rpmyum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpmyum-updateonboot-1.1.31-34.el7.noarch.rpmyum-utils-1.1.31-34.el7.noarch.rpm我把这五个rpm包下载到我的Windows电脑里，然后用WinSCP这个软件上传到redhat 7 系统里，WinSCP这个软件的使用方法就不在这里赘述了8、下载好后重新安装：[root@linuxidc ~]# lsyum-3.4.3-132.el7.centos.0.1.noarch.rpm yum-updateonboot-1.1.31-34.el7.noarch.rpmyum-metadata-parser-1.1.4-10.el7.x86_64.rpm yum-utils-1.1.31-34.el7.noarch.rpmyum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm[root@linuxidc ~]# rpm -ivh yum-*warning: yum-3.4.3-132.el7.centos.0.1.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY Preparing... ################################# [100%]Updating / installing...1:yum-metadata-parser-1.1.4-10.el7 ################################# [ 20%]2:yum-plugin-fastestmirror-1.1.31-3################################# [ 40%]3:yum-3.4.3-132.el7.centos.0.1 ################################# [ 60%]4:yum-updateonboot-1.1.31-34.el7 ################################# [ 80%]5:yum-utils-1.1.31-34.el7 ################################# [100%][root@linuxidc ~]#这次没有报错了，安装完成！！！9、新建repo 配置文件；[root@linuxidc ~]# vim /etc/yum.repos.d/CentOS-Base.repo#CentOS-Base.repo## The mirror system uses the connecting IP address of the client and the# update status of each mirror to pick mirrors that are updated to and# geographically close to the client.

虚拟机中安装Linux（Redhat）教程
虚拟机中安装Linux（Redhat）教程虚拟机中安装Linux（Redhat）教程说明：本次安装在Vmware14.0中安装，所使⽤的镜像⽂件为rhel-server-7.2-x86_64-dvd.iso⼀、创建虚拟机：1、创建新的虚拟机：2、完成虚拟机的引导（1）选择⾃定义、点击下⼀步。
（2）兼容性默认不修改：（3）客户机操作系统我们稍后安装：（4）选择要安装的客户机操作系统的类型：由于我们安装的系统时Linux，版本为Redhat7版本，就直接勾选，最后下⼀步。
（5）命名虚拟机，点击选择保存虚拟机⽂件的位置。
这⾥都⽐较随便，建议保存的位置不要在C盘。
（6）设置虚拟机中处理器的内核数量，根据⾃⼰的CPU设定。
（7）设置虚拟机的内存，根据⾃⼰物理机给，默认就可以。
（8）设置⽹络类型：这⾥⽹络类型有3种，简单说⼀下：①桥接：相当于直接连接在了物理⽹卡上来获取IP地址，访问公⽹。
如果我们获得是私有IP，我们也可以访问同⼀⽹段内的主机。
②NAT：获得私有IP地址，既可以直接连接物理⽹卡访问互联⽹，同时可以访问我们的物理主机。
③仅主机：相当于主机内部搭建了⼀个局域⽹，使得虚拟机可以访问我们的物理机或者是这台物理机上的其他虚拟机。
（9）选择I/O控制器类型：默认就好。
（10）选择虚拟机磁盘，也简单说⼀下这些磁盘：IDE：不⽀持热插拔，传输速率慢，总之，不太好SATA：⽀持热插拔，传输速率⼀般，性价⽐⾼SCSI：⽀持热插拔，传输速率快，缓存⼤，CPU占⽤低。
⼯作站、服务器级别磁盘，⽐较贵。
（12）为虚拟机分配磁盘⼤⼩：（13）指定磁盘⽂件存储的位置：（14）点击完成：3、修改虚拟机设置，识别镜像⽂件加载路径。
（1)点击主界⾯图中的地⽅（2）选择使⽤ISO映像⽂件，然后点击浏览找到Redhat7.2的镜像⽂件所存在的位置。
最后点击确定。
⼆、安装虚拟机：1、开启虚拟机：2、进⼊后点击第1项，之后按下回车开始安装。

Red Hat Enterprise Linux 7 安装整理
Red Hat Enterprise Linux 7.0 安装方法川信授课使用开始安装一、选择安装方式有3个选择项，分别是：1、直接安装Linux 7.0；2、先测试镜像是否有错，然后安装Linux 7.0（检查镜像是需要一定的时间，如果镜像没问题就直接选择第一项跳过检查直接安装）；3、进入排错。
点击“Troubleshooting”进入查看一下有5个选择项，分别是：1、用基本的图形模式安装RHEL7.0（服务器特别新或者特别就时使用，安装最基本的显卡）2、急救模式3、内存检测4、从本地硬盘启动5、返回主菜单返回到主菜单，这里就直接选择第一项开始安装然后按“Enter”进行安装二、进入选择安装语言找到中文，选择中文安装，然后点击“继续”三、进入系统设置界面1、设置时间和日期，点击“时间和日期（T）”选择时区，关键设置时间同步设置时间同步，点击打开“网络时间”点击后面的“小齿轮”进入设置与所需的服务器同步，默认的是Red Hat官方的4个服务器（如需要域本公司的服务器同步，输入IP地址或主机名，点击“＋” 添加）2、设置键盘语言，点击“键盘（K）”点击“＋” 进行添加所需的语言3、选择进入系统后的语言，点击“语言支持（L）”这里选择简体中文4、设置安装系统的方式，点击“安装源”在企业里安装方法有3种（1）插入光盘安装（2）把光盘复制到硬盘安装（3）网络安装（在企业里用的最多）可以通过检查到的安装源安装，也可以通过网络安装网络安装需要输入“IP/目录”，首先需要对目录进行共享因为是使用镜像安装的所以选择第一项“自动检测到的安装介质（A）”5、选择系统所需安装的软件，点击“软件选择”最小化安装是在命令行系统中，并没有桌面，如果需要安装桌面，点击“带GUI的服务器”。
这里选择安装了“Java平台”，选择标准安装也可以。
在实际生产中按本公司的需求进行安装软件。
6、分配磁盘空间，点击“安装位置（D）”（注意分区顺序）RHEL6最少的安装分区是3个：（1）/boot——里面有：启动文件、内核（2）swap——交换分区在内存不够时使用一般swap 是物理内存的2—2.5倍（虚拟内存）（3）/ ——剩下所有的都存放在/ 下RHEL7最少的安装分区是2个（它的swap是自动管理的，可以不分配）：（1）/boot（2）/如果需要自己手动去分配磁盘空间勾选“我要配置分区（I）”，点击“完成（D）”进入手动分区界面（1）如果需要系统自动分区，点击“点这里自动创建他们（C）”自动分配完成之后点击“完成”（2）如果是自己手动分配，点击“新挂载点将使用以下分区方案”选择“标准分区” ，然后点击“＋”创建100M 的/boot 分区（在“期望容量” 中添加大小容量是记的后面跟单位，如“100M，2G”，不加单位默认情况下是M ）创建2G 的swap 分区把剩下的所有磁盘空间给/ （期望容量不填写就默认所有）可以选择磁盘格式，RHEL7 中默认是xfs 格式（最大单个文件是2T），也可以选择RHEL6 的格式ext4磁盘手动分配完成，点击“完成”弹出磁盘变更的提示，点击“接受更改”7、设置网络和计算机名，点击“网络和主机名（N）”开启网络，点击“配置” 进行网络设置更改主机名，设置完，点击“完成”主机名一般的设置方法是：用途.域名如：现在不设置以后设置也可以，我这里用简单的 sxl.host 命名四、设置完成后，点击“开始安装”五、系统开始安装，RHEL7 在安装的过程中设置ROOT密码和创建用户1、设置ROOT密码，如果密码设置简单需要点击2次完成2、创建用户，注意“将此用户作为管理员”也就是拥有root的一些权限，同样密码简单需要按2次“完成”点击“高级（A）” ，设置用户一些其他信息ROOT密码和用户设置完成，等待安装 RHEL7 ，可以看到一个有1191个安装包（需要一定的安装时间）六、安装完成，点击“结束配置（F）”然后再等会儿提示重新启动，点击“重启”七、重启后，选择“第一项”进行系统初始化的设置，点击“许可信息（L）”进入勾选“我同意许可协议（A）”，点击“完成”点击“完成配置（F）”进入Kdump，Kdump的作用是：系统在崩溃时记录下崩溃的原因，方便进行系统的修复。
linux系统安装r语言环境方式及问题详细解决方式
linux 下安装R环境方式、问题及详细解决方案一、下载wget 、解压：tar -zxvf 、安装(固然也可以跳过)yumyum install readline-develyum install libXt-devel./configure4、配置环境并编译安装# 若是利用rJava需要加上--enable-R-shlib (这个我不需要，所以加入到后面) # 若是3没安装, 那么后面加上：--with-readline=no --with-x=no./configure --prefix=/usr/make install（若是：./configure 后报错错误：configure: error: No F77 compiler found 说明R语言需要fortran compiler，也就是说，在上面尝试寻觅了若干种Fortran 编译器未果以后，提示你没有安装任何一种可以利用的fortran 77 编译器。
随意装个gfortran 就好了。
