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 -version3.安装 ncurses 和 bison# yum -y install ncurses-devel# yum -y install bison4. 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/data6. 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 install7. 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/mysqldatadir = /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 mysqld9. 设置启动脚本变量 # vi /etc/rc.d/init.d/mysqldbasedir=/u01/app/mysqldatadir=/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 directoryStarting MySQL. [ OK ]如果这一步出现错误：Starting MySQL. ERROR! The server quit without updating PID file
除了网络搜索到的常见kill进程等方法之外，如果不起作用可参考以下页面的方法：

尝试了其中的solution 2 移除配置文件解决了问题
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 directoryShutting 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 directoryStarting 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。）Enter password: Welcome to the MySQL monitor.
