Linux下编译安装MySQL
下面是在 CentOS 6.5 下编译安装 MySQL 5.6.20 。
1. 首先卸载系统自带的 mysql
# yum remove mysql
2.安装cmake
下载cmake源码
# wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz
# tar xzfv cmake-2.8.5.tar.gz
# cd cmake-2.8.5
# ./configure
（ 如果提示没安装C++编译器就先安装C++编译器：# yum -y install gcc-c++ ）
# make
# make install
查看 cmake 版本
# cmake -version
3.安装 ncurses 和 bison
# yum -y install ncurses-devel
# yum -y install bison
4. 创建mysql组和用户
# groupadd mysql
# useradd -g mysql mysql
5. 创建数据库目录及分配访问权限
# mkdir -p /u01/app/mysql
# chown -R root:mysql /u01/app/mysql
# chown -R mysql:mysql /u01/app/mysql/data
6. 编译安装mysql
下载mysql源码
# wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.20.tar.gz
# tar xzfv mysql-5.6.20.tar.gz
# cd mysql-5.6.20
# cmake . -DCMAKE_INSTALL_PREFIX=/u01/app/mysql -DMYSQL_DATADIR=/u01/app/mysql/data -DSYSCONFDIR=/etc
参数说明：
-DCMAKE_INSTALL_PREFIX //安装根目录
-DINSTALL_DATADIR //数据存储目录
-DSYSCONFDIR //配置文件(my.cnf)目录
# make
# make install
7. 配置 mysql
# cd /u01/app/mysql
# cp ./support-files/my-default.cnf /etc/my.cnf
# vi /etc/my.cnf
在 [mysqld] 段修改
basedir = /u01/app/mysql
datadir = /u01/app/mysql/data
保存退出编辑。
8. 初始化数据库
# cd /u01/app/mysql
# ./scripts/mysql_install_db --basedir=/u01/app/mysql --datadir=/u01/app/mysql/data --defaults-file=/etc/my.cnf --user=mysql
# cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
# chmod 755 /etc/rc.d/init.d/mysqld
# chkconfig --add mysqld
9. 设置启动脚本变量
# vi /etc/rc.d/init.d/mysqld
basedir=/u01/app/mysql
datadir=/u01/app/mysql/data
保存退出。
10. 设置变量环境
# echo "PATH=$PATH:/u01/app/mysql/bin" >> /etc/profile （永久生效）
# export PATH=$PATH:/u01/app/mysql/bin （当前生效）
11. 启动服务
# service mysqld start
/etc/init.d/mysqld: line 46: /u01/app/mysql: is a directory
/etc/init.d/mysqld: line 47: /u01/app/mysql/data: is a directory
Starting MySQL. [ OK ]
12. 设置数据库管理员root密码
# mysqladmin -u root password ‘123456‘
（注：在当前会话窗口操作，否则会出现 “mysqladmin: command not found” 错误，除非重新启动系统。）
重新启动服务
# service mysqld restart
/etc/init.d/mysqld: line 46: /u01/app/mysql: is a directory
/etc/init.d/mysqld: line 47: /u01/app/mysql/data: is a directory
/etc/init.d/mysqld: line 46: /u01/app/mysql: is a directory
/etc/init.d/mysqld: line 47: /u01/app/mysql/data: is a directory
Shutting down MySQL. [ OK ]
/etc/init.d/mysqld: line 46: /u01/app/mysql: is a directory
/etc/init.d/mysqld: line 47: /u01/app/mysql/data: is a directory
Starting MySQL. [ OK ]
13. 进入 MySQL
# mysql -u root -p
（注：在当前会话窗口操作，否则会出现 “mysql: command not found” 错误，除非重新启动系统。）
