短信预约 -IT技能 免费直播动态提醒
一、创建msql用户
#添加运行mysql的用户,禁止该用户登录系统
[root@openstack-01 ~]# useradd mysql -s /sbin/nologin
二、创建相关目录
#创建目录
[root@openstack-01 ~]# mkdir /data/mysql/mysql3306/{conf,data,logs,tmp} -p
#修改目录权限
[root@openstack-01 ~]# chown -R mysql.mysql /data/mysql
三、创建配置文件
[root@openstack-01 ~]# cat /data/mysql/mysql3306/conf/mysql_3306.cnf
#my.cnf

四、初始化mysql
#开始初始化
[root@openstack-01 ~]# /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/bin/mysqld --defaults-file=/data/mysql/mysql3306/conf/mysql_3306.cnf --basedir=/usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/ --initialize
#查看初始化后的结果
[root@openstack-01 ~]# ll /data/mysql/mysql3306/data/
total 409648
-rw-r----- 1 mysql mysql 56 Jun 10 17:27 auto.cnf

#获取root用户密码
[root@openstack-01 ~]# grep password /data/mysql/mysql3306/data/error.log |awk '{print $11}'

五、启动mysql
[root@openstack-01 ~]# /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/bin/mysqld --defaults-file=/data/mysql/mysql3306/conf/mysql_3306.cnf &
[1] 14632
[root@openstack-01 ~]# ps aux |grep mysql |grep -v grep

[root@openstack-01 ~]# ss -tnl |grep 3306
LISTEN 0 70 :::3306 :::*
#登录mysql
[root@openstack-01 ~]# /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/bin/mysql -u root -p -S /tmp/mysql3306.sock
