创建用户：
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql

chown -R mysql.mysql /data/mysqldata
chown -R mysql.mysql /data/software/mysql

初始化数据：
mysqld --initialize-insecure --user=mysql --basedir=/data/software/mysql --datadir=/data/mysqldata

vim /etc/my.cnf

设置环境变量PATH：

vim /etc/profile

加入： export PATH=$PATH:/data/software/mysql/bin

加入sysctl管理：

cp /data/software/mysql/support-files/mysql.server /etc/init.d/mysqld

启动：

service mysqld start
