IP地址已经修改过来，与宿主机在一个网段（Bridge模式）。但是，MySQL无法连接上。

[root@localhost ~]# mysql
ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2)

[root@localhost ~]# ps -A | grep -i mysql
[root@localhost ~]# service mysql start
Redirecting to /bin/systemctl start mysql.service
Failed to start mysql.service: Unit not found.

[root@localhost ~]# ps -ef|grep mysql
root 4560 4126 0 20:40 pts/0 00:00:00 grep --color=auto mysql

 

[root@localhost ~]# /etc/init.d/mysql start
bash: /etc/init.d/mysql: 没有那个文件或目录

在/etc/rc.d/init.d里面没有mysqld，

[root@localhost ~]# /usr/bin/mysqladmin version
/usr/bin/mysqladmin: connect to server at ‘localhost‘ failed
error: ‘Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2)‘
Check that mysqld is running and that the socket: ‘/var/lib/mysql/mysql.sock‘ exists!

看了很多帖子，实际都不是这个问题。最后这个帖子解决了，老外遇到的。还是外国的帖子有价值些，内容广些，原创多。Google很重要。

So the 3 steps to enable and run MariaDB are as follows, assuming it was previously installed during the initial setup for the system or with yum install mariadb mariadb-server:

systemctl start mariadb.service
systemctl enable mariadb.service
mysql_secure_installation
