安装测试
    [root@localhost perl]# mysql
ERROR 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
    在搜索里找不到mysql执行程序，只有rpm安装包
    在“服务”-看到了新增的 mysqld 打勾，restart
    [root@localhost perl]# mysql
Welcome to the MySQL monitor.  Commands end with ; or g.
Your MySQL connection id is 1 to server version: 3.23.52

Type 'help;' or 'h' for help. Type 'c' to clear the buffer.
mysql>

mysql成功安装并启动

因为缺省情况下mysql的root用户没有口令，使用下列
[root@localhost perl]# mysqladmin -u root password 747858969
[root@localhost perl]# mysql
ERROR 1045: Access denied for user: 'root@localhost' (Using password: NO)

[root@localhost etc]# mysql -u root -p
Enter password:****
mysql>
