【MySQL】源码编译安装和配置MySql5.5.32（单实例）

【MySQL】源码编译安装和配置MySql5.5.32（单实例）【需求描述】在CentOS环境中，通过编译源码的⽅式，安装并且配置“单实例”的MySQL5.5.32数据库。

MySQL的安装⽬录为：/application/mysql-5.5.32MySQL数据⽂件的安装⽬录为：/application/mysql-5.5.32/dataMySQL默认的字符编码为：UTF8【环境参数】VMware：10.0.1Host：Win7DB：MySql 5.5.32编译⼯具：cmake-2.8.8.tar.gz其他依赖：ncurses-devel-5.7-3.20090208.el6.x86_64.rpmClient：CentOS 6.5 x86_64,i686，最⼩化安装（Minimal）。

在安装⾃定义组件包时，(1)Base System只安装了Base，Compatibility Libraries和Debugging Tools。

(2)Development只安装了Development Tools。

【软件下载】(1)MySql下载地址：选择“Generic Linux (Architecture Independent), Compressed TAR Archive”这个版本的来下载。

(2)下载cmakeCMake是⼀个跨平台的安装（编译）⼯具，可以⽤简单的语句来描述所有平台的安装(编译过程)。

他能够输出各种各样的makefile或者project⽂件，能测试编译器所⽀持的C++特性,类似UNIX下的automake。

只是 CMake 的组态档取名为 CmakeLists.txt。

(3)下载ncurse-devel依赖包的百度云盘分享：【具体步骤】1、查看系统环境[root@centos65-mini ~]# cat /etc/redhat-releaseCentOS release 6.5 (Final)[root@centos65-mini ~]#[root@centos65-mini ~]#[root@centos65-mini ~]# uname -r2.6.32-431.el6.x86_64[root@centos65-mini ~]#2、安装相关软件包(1) 配置、编译和安装cmake编译⼯具①在当前⽬录，解压缩cmake-2.8.8.tar.gz# tar –zxvf cmake-2.8.8.tar.gz②从当前⽬录切换到cmake-2.8.8⽬录中，# cd cmake-2.8.8③执⾏命令“#./configure”来配置cmake⼯具。

CentOS_6.6用rpm方式安装MySql

CentOS_6.6用rpm方式安装MySql卸载旧版本MySql检查MySQL及相关RPM包，是否安装，如果有安装，则移除[root@MyServer010 ftp]# rpm -qa|grep mysqlmysql-libs-5.1.73-3.el6_5.x86_64[root@MyServer010 ftp]# yum -y remove mysql-libs*移除MySql也可以用下面的命令rpm -e --nodeps mysql-libs-5.1.73-3.el6_5.x86_64下载的MySql文件[root@MyServer010 ftp]# ll-rw-r--r-- 1 root root 18596528 10月21 14:31 MySQL-client-5.6.27-1.el6.x86_64.rpm-rw-r--r-- 1 root root 3392620 10月21 14:31 MySQL-devel-5.6.27-1.el6.x86_64.rpm-rw-r--r-- 1 root root 55950588 10月21 14:32 MySQL-server-5.6.27-1.el6.x86_64.rpm安装MySql[root@MyServer010 ftp]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm注意：安装server时，会有下面的提示，会告知root第一次登录所需的随机密码文件位置。

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !You will find that password in '/root/.mysql_secret'.You must change that password on your first connect,no other statement but 'SET PASSWORD' will be accepted.See the manual for the semantics of the 'password expired' flag.Also, the account for the anonymous user has been removed.In addition, you can run:/usr/bin/mysql_secure_installation下面接着安装[root@MyServer010 ftp]# rpm -ivh MySQL-devel-5.6.27-1.el6.x86_64.rpm[root@MyServer010 ftp]# rpm -ivh MySQL-client-5.6.27-1.el6.x86_64.rpm初始化数据库及设置密码[root@MyServer010 ftp]# /usr/bin/mysql_install_db[root@MyServer010 ftp]# service mysql startStarting MySQL..

CentOS下Apache、PHP、MySQL安装配置

1. 安装Apahce, PHP,以及php连接mysql库组件。

yum -y install httpd php php-mysql2. 配置开机启动服务/sbin/chkconfig httpd on [设置apache服务器httpd服务开机启动]/sbin/chkconfig --add mysqld [在服务清单中添加mysql服务]/sbin/chkconfig mysqld on [设置mysql服务开机启动]/sbin/service httpd start [启动httpd服务,与开机启动无关]3.//安装apache扩展yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql//安装php的扩展yum install php-gdyum -y install php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc4.apache的配置文件是/etc/httpd/conf下modules放在/usr/lib/httpd下php的配置文件在/etc/php.d/下和/etc/php.iniphp的modules放在/usr/lib/php/modules下apache 默认支持php配置zendoptimizer-3.3.3 cd 目录install 安装过程指定httpd控制文件/etc/rc.d/init.d/httpd路径/etc/httpd配置cronolog进行日志分割下载/download/index.html./configure --prefix /usr/local/cronologmakemake install即可httpd-vhost.conf中的日志设置项可以为：ErrorLog “|/usr/local/cronolog/sbin/cronolog/home/www/apache_logs/-error_log%Y%m%d" CustomLog |/usr/local/cronolog/sbin/cronolog /home/www/apache_logs/-access_log%Y%m%d"combinedmount -t nfs 192.168.0.252:/home/www/wwwroot/bbs /home/www/wwwroot/bbs出现：Document root must be a directory解决办法?关闭selinux setenforce 01.前言CentOS（Community ENTerprise Operating System）是Linux发行版之一，它是来自于Red Hat Enterprise Linux依照开放源代码规定释出的源代码所编译而成。

CentOS7安装MySQL8.0小计

CentOS7安装MySQL8.0⼩计之前讲配置⽂件和权限的时候有很多MySQL8的知识，有同志说安装不太⼀样，希望发个⽂，我这边简单演⽰⼀下1.下载MySQL提供的CentOS7的yum源官⽅⽂档：<>过程中有不太懂的可以看我之前写的这篇⽂章：<>地址：安装yum源：yum install centos7.mysql.rpm -y安装MySQL8.0 yum install mysql-community-server -y启动mysql systemctl start mysqld设置开机启动mysql systemctl enable mysqld2.查看初始密码cat /var/log/mysqld.log | grep "password"安全初始化mysql_secure_installation3.权限相关详细可以查看上次写的⽂章：⽤root账号登录mysql -uroot -p创建⽤户dnt create user dnt@'%' identified by '含⼤⼩写字母+数字的密码';查看当前有哪些⽤户select user,authentication_string,host from er;给⽤户dnt分配数据库dotnetcrazy的所有权限grant all on dotnetcrazy.* to dnt;刷新权限flush privileges;显⽰新⽤户有哪些权限show grants for dnt;4.root权限去修改/etc/f在[mysqld]选项下新增：bind-address=0.0.0.0开放3306端⼝的远程访问权限：firewall-cmd --zone=public --add-port=3306/tcp --permanent刷新防⽕墙规则firewall-cmd --reload重启MySQL：systemctl restart mysqld测试1.安装附录# 下载yum源（curl是系统⾃带的）# curl https:////mysql80-community-release-el7-3.noarch.rpm >

CentOS7安装MYSQL5.7.7

1
#groupadd mysql
#useradd-r-g mysql mysql---新建msyql用户禁止登录shell
2
# cd /usr/local/---切换到存放源码包所在目录（这里也是安装目录）
# tar -xvf mysql-5.7.7-m16-linux-glibc2.5-x86_64.tar.gz---在当前目录解压通用编译包
1、初始化数据库时不再使用“--mysql_install_db”而是使用了“--initialize”或是”--initialize-insecure”，区别在于“--initialize”会生成一个随机密码而”--initialize-insecure”不会生成密码。
2、不在生成.mysql_secret文件；
3、不再创建匿名用户MySQL账户；
4、不再创建测试数据库。
编译
1
1).下载cmake-3.2.1.tar.gz---新版的MySQL用CMAKE编译安装
/download/
2).下载ncurses-5.9.tar.gz---安装MySQL时需要
ftp:///gnu/ncurses/
-DMYSQL_DATADIR=/usr/local/mysql/data/\---数据库目录
-DDEFAULT_CHARSET=utf8\---字符集支持
-DDEFAULT_COLLATION=utf8_general_ci\---字符集支持
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock\---指定mysql.sock位置
介绍：MySQL的安装方法有多种，如yum安装，rpm包安装，rpm源码编译安装，源码编译安装，通用预编译包安装。其中yum安装和rpm包安装比较简单，软件安装时会自动默认设置，但可定制性弱版也较旧。源码包编译安装可定制性强版本也新。下面是通用预编译包安装和源码编译安装的方法，MySQL的版本为最新的5.7.7版。在MySQL5.7.7中有一些新的特性如：

Centos 安装与配置 jdk、tomcat、mysql

Centos 装jdk、tomcat1. 安装jdk·将下载下来的jdk-7u7-linux-i586.rpm通过ftp上传到linux服务器。

·检查系统是否已经安装了jdk：#rpm –qa | grep jdk //查看系统中已经安装的程序包含jdk的Centos 默认情况下会出现：java-1.6.0-openjdk-1.6.0.0-1.22.1.9.8.el5_6·首先卸载原有的jdk：#yum –y remove java-1.6.0-openjdk-1.6.0.0-1.22.1.9.8.el5_6#yum –y remove java*·卸载完成后重新安装：#rpm –ivh jdk-7u7-linux-i586.rpm //安装#rpm –qa | grep jdk //检查安装情况出现：jdk-1.7.0_07-fcs //表示已经安装成功·执行java javac 都可以看到相应的帮助信息，也可执行java –version 查看安装jdk的版本号，看到与所安装的jdk版本号相对应的版本号表示安装成功。

Jdk的安装目录一般是在：/usr/java下会根据jdk的版本再创建一个目录，如：/usr/java/jdk1.7.0_07·配置环境变量：#vi /etc/profile//在文件末尾添加：JA V A_HOME=/usr/java/jdk1.7.0_07PATH=$PATH:$JA V A_HOME/binCLASSPATH=.:$JA V A_HOME/lib/dt.jar:$JA V A_HOME/bli/tools.jar:$JA V A_HOM E/libJRE_HOME=$JA V A_HOME/jre存盘退出#export JA V A_HOME PATH CLASSPATH JRE_HOME //分发配置#source /etc/profile //重新执行配置2. 安装tomcat·将下载下来的apache-tomcat-6.0.20.tar.gz通过ftp上传到linux服务器。

CENTOS7环境安装MySQL5.6(rpm_二进制_源代码编译三种方式)

CENTOS7环境安装MySQL软件环境虚拟机：VMware® Workstation-10.0.1 build-1379776-Win Linux：Centos 7 X86_64MySQL Database: MySQL-5.6.24系统环境MySQL软件安装一、使用RPM安装。

安装采用RPM安装包安装。

下载mysql:/downloads/mysql/打开页面之后，在Select Platform:下选择linux Generic下载后的包为名称为：MySQL-5.6.24-1.linux_glibc2.5.x86_64.rpm-bundle.tar（一）卸载原有MySQL或者Mariadb安装程序1、CentOs7版本默认情况下安装了mariadb-libs，必须先卸载才可以继续安装MySql。

a) 查找以前是否安装mariadb-libs# rpm -qa | grep -i mariadb-libsb)卸载已经安装的mariadb-libs# yum remove mariadb-libs-5.5.41-2.el7_0.x86_642、查找以前是否安装MySQL# rpm -qa | grep -i mysql--说明已经有安装了MySQL程序a)停止mysql服务# sudo service mysql stop或者：# ps -A | grep mysql# kill -9 进程号b)删除之前安装的mysql# rpm -ve MySQL-server-5.6.24-1.linux_glibc2.5.x86_64# rpm -ve MySQL-client-5.6.24-1.linux_glibc2.5.x86_64c)查找之前老版本mysql的目录、并且删除老版本mysql的文件和库# find / -name mysql【查找结果如下】# find / -name mysql/var/lib/mysql/usr/lib64/mysql/usr/local/mysql/usr/local/mysql/data/mysql【删除对应的目录】# rm -rf /var/lib/mysql# rm -rf /usr/lib64/mysql# rm -rf /usr/local/mysql【删除配置文档】# rm -rf /etc/fd)再次查找机器是否安装mysql# rpm -qa|grep -i mysql【无结果，说明已经卸载彻底、接下来直接安装mysql即可】（二）下载和解压、安装【创建一个任意名称文件夹，如：rpm】# mkdir rpm# cd rpm【下载安装包的压缩文档】# wget /Downloads/MySQL-5.6/MySQL-5.6.17-1.el6.x8 6_64.rpm-bundle.tar# tar –xvf MySQL-5.6.17-1.el6.x86_64.rpm-bundle.tar【创建mysql用户和数据目录】#groupadd mysql#useradd -r -g mysql mysql#cd /usr/local#sudo mkdir mysql#cd mysql#sudo mkdir mysql#sudo chown -R mysql .#sudo chgrp -R mysql .【安装RPM包】#sudo rpm -ivh MySQL-server-5.6.24-1.linux_glibc2.5.x86_64.rpm如果出现错误：FATAL ERROR: please install the following Perl modules beforeexecuting ./scripts/mysql_install_db:Data::Dumper先用yum list 查找下module:# yum list|grep -i perl-modul*# yum install -y perl-Module-Install.noarch#rpm -ev MySQL-server-5.6.24-1.linux_glibc2.5.x86_64重新执行：#sudo rpm -ivh MySQL-server-5.6.24-1.linux_glibc2.5.x86_64.rpm【初始化MySql配置文件】#cp f /etc/f可以简单修改配置如下。

那么你知道Linux centos7环境下MySQL安装教程么?接下来是小编为大家收集的Linux centos7环境下MySQL安装教程，欢迎大家阅读：Linux centos7环境下MySQL安装教程1)、my.ini 保存到/etc/my.ini2)、用户权限，单独用户执行一、查找以前是否安装有mysql，使用下面命令：rpm –qa | grep -i mysql如果显示有如下包则说明已安装mysqlmysql-4.1.12-3.RHEL4.1mysqlclient10-3.23.58-4.RHEL4.1二、下载mysql解压包mysql-5.7.17-linux-glibc2.5-x86_64.tar (去网站上下载)网址：/mysql/MySQL-5.7/也可以在Linux操作系统底下进行下载，输入如下命令wget /mysql/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz创建目录software用于存放我们待会要下载的mysql包，先去到该目录输入命令：cd /software下载完成后，你会在software目录下看到多出一份mysql安装包文件三、建立用户，以及mysql的目录1、groupadd mysql #建立一个mysql的组2、useradd -r -g mysqlmysql #建立mysql用户，并且把用户放到mysql组3、passwd mysql #给mysql用户设置一个密码四、解压mysql安装包1、先把tar.gz包移动到/usr/local 目录下，输入命令mv /software/MySQL/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz/usr/local2、解压tar.gz包先去到/usr/local 目录下，输入命令cd /usr/local解压命令 tarzxvfmysql-5.7.17-linux-glibc2.5-x86_64.tar.gz输入查看目录命令 ll会发现多出目录 mysql-5.7.17-linux-glibc2.5-x86_64注意：没有data 目录，my.ini文件在support-files 目录下3、改一下目录名字为 /usr/local/mysql(这是linux下mysql的默认安装安装目录)把解压出来的文件改下名字，改为mysql输入命令： mv mysql-5.7.17-linux-glibc2.5-x86_64 mysql五、配置相关的启动配置文件首先要去到support-files/文件目录下输入命令： cd support-files/1、复制f 到 /etc/f (mysql启动时自动读取)输入命令 f /etc/f2、解决乱码问题输入命令：vi /etc/f (进入可编辑状态)更改：[mysql]default-character-set=utf8(表示解决客户端乱码问题)[mysqld]default-storage-engine=INNODBcharacter_set_server=utf8(表示解决服务端乱码问题)3、复制mysql.server 到/etc/init.d/ 目录下【目的想实现mysqld -install这样开机自动执行效果】输入命令 cp mysql.server /etc/init.d/mysql (mysql是服务名)注意：/etc/init.d/ 目录，等效于注册表HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services记录有那些服务4、修改/etc/init.d/mysql 参数输入命令 vi /etc/init.d/mysql给与两个目录位置basedir=/usr/local/mysqldatadir=/usr/local/mysql/data5、给目录/usr/local/mysql 更改拥有者输入命令 chown -R mysql:mysql /usr/local/mysql/六、初始化mysql的数据库1、初始化mysqlmysql_install_db (老版本的做法)新版本：初始化输入命令./mysqld --initialize --user=mysql--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 生成出一个data目录，代表数据库已经初始化成功并且mysql的root用户生成一个临时密码：(记录下临时密码XXX)2、给数据库加密输入命令./mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data3、启动mysql输入命令 ./mysqld_safe --user=mysql & (&符表示提交到后台运行mysql服务)七、进入客户端1、登录输入命令 ./mysql -uroot -p然后再输入你的临时密码2、修改密码输入命令set password=password(‘xxxx')八、window远程访问Linux虚拟机的mysql先来看看数据库结构1、关闭防火墙 (或者给防火墙开放端口)，这样window才能连接上输入命令 systemctl stop firewalld.service2、给Windows授权输入命令mysql>grant all privileges on *.* toroot@'%' identified by '123456';mysql>use mysql;mysql>select host,user from user;【多出一条远程登录用户记录】mysql>flush privileges;3、远程链接数据库，或者重启(init 6)。

CentOS7 MariaDB10(MySql)相关安装配置

依次依据自己的需要，点选下图中的1、2、3部分，最终会得到4部分内容。

[root@localhost /]# im /etc/yum.repos.d/MariaDB.repo
[root@localhost /]# yum makecache
[root@localhost /]# yum install mariadb-server mariadb-client
[root@localhost /]# rpm -qa|grep MariaDB
[root@localhost /]# mysql
最新稳定版本，估计与Oracle公司达成某个协议，可以看到上面截图中有如下这么一句话
连接Windows版本的MariaDB(在下载MariaDB 10的版本，会自带HeidiSQL)，配置信息如下图：
的权限，需要予以调整。

调整顺序如下所示，调整完毕后，测试连接是成功的。

哦，对了，在这之前需要就爱那个CentOS的防火墙关掉，否则会网络会不通的，错误如下图：
关闭CentOS的处理方法如下图：。

mysql数据库搭建流程

mysql数据库搭建流程MySQL是一种广泛使用的关系型数据库管理系统，是开源软件，各个平台上都可以使用，具有性能稳定、操作简易等优点，成为非常流行的数据库选择。

下面就来介绍一下MySQL数据库搭建流程。

1.安装MySQL数据库管理系统首先需要下载对应平台的MySQL安装包，这里以Windows平台为例。

下载完成后，双击运行安装程序，按照提示完成MySQL安装，在过程中需要设置MySQL的管理员账户和密码，并可以选择安装的组件。

2.配置MySQL服务在MySQL安装完成后，需要进行服务的配置。

在Windows平台下，打开“服务”管理器，找到MySQL服务，并启动服务。

如果MySQL服务启动失败，可能需要更改MySQL配置文件my.ini的默认路径，将MySQL程序路径修改为正确路径，即可启动服务。

3.创建数据库和用户在MySQL服务已经成功启动后，需要在MySQL中创建一个新数据库以及一个管理用户。

可以使用MySQL客户端工具，如MySQL Workbench等工具进行创建。

首先登录MySQL，在QUERY上输入CREATE DATABASE 数据库名字;，完成创建数据库。

然后在QUERY上输入CREATE USER '用户名称'@'localhost' IDENTIFIED BY '用户密码';，完成创建用户。

4.为用户授权完成用户的创建后，需要为其授权，以便用户可以对创建的数据库进行操作。

使用GRANT语句进行授权，在QUERY上输入GRANT ALL PRIVILEGES ON 数据库名字.* TO '用户名称'@'localhost' IDENTIFIED BY '用户密码';，完成用户的授权。

5.远程访问的配置如果需要让外部机器可以访问MySQL，则需要进行相关配置，如取消bind address、开放MySQL默认端口3306等。

Centos7中mysql安装以及命令

Centos7中mysql安装以及命令Centos7将默认数据库mysql替换成了Mariadb，⾸先要卸载默认数据库的[root@localhost ~]# rpm -qa|grep mariadbmariadb-libs-5.5.52-1.el7.x86_64[root@localhost ~]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64开始安装mysql5.72. 进⼊/usr/local/⽬录，并解压[root@localhost local]#tar -zxvf mysql-advanced-5.6.24-linux-glibc2.5-x86_64.tar.gz将解压好的⽂件夹重命名为mysql5.73、创建⼀个mysql⽤户组和mysql的⽤户名[root@localhost local]# groupadd mysql[root@localhost local]# useradd -g mysql mysql //将mysql⽤户添加到mysql的⽤户组中4. 进⼊mysql5.7⽬录，并创建两个⽬录[root@localhost mysql5.7]# mkdir data[root@localhost mysql5.7]# mdir logs创建⼀个配置⽂件 f[root@localhost mysql5.7]# vim f关于mysql的配置⽂件 f配置 , 以下先给⼀个例⼦：[client]port = 3306socket = /var/lib/mysql/mysql.sock[mysql]#这个配置段设置启动MySQL服务的条件；在这种情况下，no-auto-rehash确保这个服务启动得⽐较快。

Centos7下安装MySQL8.0.23的步骤（小白入门级别）

Centos7下安装MySQL8.0.23的步骤（⼩⽩⼊门级别）⾸先简单介绍⼀下什么叫MySQL；数据库简⽽⾔之就是存储数据的仓库，为了⽅便数据的存储和管理，它将数据按照特定的规律存储在磁盘上。

是为了实现⼀定的⽬的，按照某种规则组织起来的数据的集合；MySQL是⼀种开放源代码的关系型数据库管理系统（RDBMS），使⽤最常⽤的数据库管理语⾔--结构化bai查询语⾔（SQL）进⾏数据库管理。

通过数据库管理系统，可以有效的组织和管理存储在数据库中的数据。

那么我们常见的数据库模型：1，关系型数据库 MySql Oracle SQL Server2，⾮关系型数据库 2,1⽂档存储数据库 MongDB 2,2键值存储数据库 Redis Memcached 2,3列存储数据库 HBase 2,4图形数据库 Neo4J关于数据库在公司⾯试的题⽬都有那些呢？ 1，SQL语句操作数据库 2，SQL语句操作表结构 3，表和类之间的关系字段和属性之间的关系表对应的是java中的类，⽤来存储数据库中取出的数据字段名（列）和类中的成员变量属性⼀致表中的⾏根据类创建的对象3，SQL语句的介绍： MySql不认识java，那么就需要交互，需⽤到数据库认识的语⾔ SQL语句是数据代码库⼀⼂环境虚拟机： centos7MYSQL:mysql-8.0.23-1.el7.x86_64.rpm-bundle①⾸先要去把MySQL安装包下好①⼂②⼂③⼂④⼂⑤⼂按照以上步骤就将mysqi压缩包下载到电脑上了⼆⼂下⾯打开虚拟机并且使⽤远程⼯具xshell连接&CRT连接。

4.MySQL数据库初始化：（1）.于mysql版本升级的原因，初始化要用到的mysqld命令不在之前的/usr/local/mysql 目录，所以我们要进行查找。

（2）.Unix和Unix系列系统中，有一点是很重要的，那就是确保数据库目录与文件的所有者为mysql登录账户，以便在你运行mysqld服务的时候，mysql服务可以对这些目录和文件进行读取与写入操作。
