安装准备
按照如下步骤安装,root用户执行
shell> groupadd -g 500 mysql
shell> useradd -g mysql -md /home/mysql -s /bin/bash mysql
shell> passwd mysql
shell> cd /usr/local
shell> ln -s mysql-5.7*-linux-glibc2.5-x86_64 mysql
shell> chmod 775 -R mysql*
shell> chown -R mysql.mysql mysql*
shell> mkdir -p /mysqldata/mysql_data
shell> chmod 775 /mysqldata/mysql_data
shell> chown -R mysql.mysql /mysqldata
shell> mkdir -p /mysql_backup
shell> chmod 775 /mysql_backup
shell> chown -R mysql.mysql /mysql_backup

初始化
Mysql5.7:
shell> bin/mysqld --initialize --user=mysql # MySQL 5.7.6 and up
mysql5.6:
shell> scripts/mysql_install_db --user=mysql
开启ssl连接(可选)
shell> bin/mysql_ssl_rsa_setup # MySQL 5.7.6 and up
启动mysql
启动命令
shell> bin/mysqld_safe --user=mysql &
第一次登录要查看错误日志里面生成的临时密码
cd /mysqldata/mysql_data
less error.log

配置启动服务（7以下需设置启动级别）
shell> cp support-files/mysql.server /etc/init.d/mysqld
添加mysql到服务开机启动chkconfig --add mysqld
chkconfig --list|grep mysql
如果启动级别不对，则执行下面命令修改，否则忽略下面命令
chkconfig --level 2345 mysqld on
centos 7以上设置开机启动
