进入mysql目录

编辑mysql配置文件

[mysqld]

socket=/usr/local/mysql/mysql.sock

port=3306

user=mysql

basedir=/usr/local/mysql

datadir=/usr/local/mysql/data

max_allowed_packet=128M

[mysqld_safe]

log-error=/usr/local/mysql/mariadb/mariadb.log

pid-file=/usr/local/mysql/run/mariadb/mariadb.pid

[client]

port=3306

socket=/usr/local/mysql/mysql.sock

!includedir /etc/my.cnf.d

编辑mysql环境配置文件

初始化mysql :/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

./mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

复制启动文件到系统启动路径下：cp support-files/mysql. server /etc/rc.d/init.d/mysql

初始化mysql 并得到初始密码

启动如果报错就报log目录已经文件给最高权限即可

启动命令：service mysqld start

重新启动命令：systemctl restart mysqld.service

停止启动命令：systemctl stop mysqld.service

终极启动命令：/etc/init.d/mysql start
