系统环境:Centos6.5
1、下载源码包
[monster@localhost download]$wgethttp://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.49-linux2.6-x86_64.tar.gz
解压到 /usr/local/ 目录下
[monster@localhost download]$ cd /usr/local/
[monster@localhost local]$ sudo tar -xf /opt/download/mysql-5.5.49-linux2.6-x86_64.tar.gz
为了方便后续操作,为该目录建立符号链接
[monster@localhost local]$ sudo ln -s mysql-5.5.49-linux2.6-x86_64/ mysql
2、检查是否安装了相应的软件包
[monster@localhost local]$ sudo rpm -qa | grep -i mysql
如果已安装了相应的xxxxx,为了防止安装时覆盖错误,先卸载xxxxx,注意加--nodeps选项,忽略依赖项
[monster@localhost local]$ sudo rpm -exxxxx --nodeps
/usr/local/mysql目录结构
3、添加mysql组和mysql用户,用于设置mysql安装目录文件的所有者和所属组
[monster@localhost local]$ sudo groupadd mysql
[monster@localhost local]$ sudo useradd -r -g mysql
4、更改mysql目录所属组和用户
[monster@localhost local]$ cd mysql
[monster@localhost mysql]$ sudo chown -R mysql:mysql .
5、初始化数据库
[monster@localhost mysql]$ sudoscripts/mysql_install_db --user=mysql
6、拷贝配置文件
[monster@localhost mysql]$ sudo cp support-files/my-medium.cnf /etc/my.cnf
7、将mysqld服务加入开机自启
[monster@localhost mysql]$ sudo cp support-files/mysql.server /etc/init.d/mysqld
[monster@localhost mysql]$ sudo chkconfig --add mysqld
8、启动mysqld服务
[monster@localhost mysql]$ sudo service mysqld start
