2. 使用命令show global variables like ‘port’;查看端口号
mysql> show global variables like ‘port’; +—————+——-+ | Variable_name | Value | +—————+——-+ | port | 3306 | +—————+——-+ 1 row in set (0.00 sec)
3. 修改端口，编辑/etc/my.cnf文件，早期版本有可能是my.conf文件名，增加端口参数，并且设定端口，注意该端口未被使用，保存退出。
root@test etc]# vi my.cnf [mysqld] port=3506 datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid “my.cnf” 11L, 261C written [root@test etc]#
4. 重新启动mysql [root@test ~]# /etc/init.d/mysqld restart Stopping mysqld: [ OK ] Starting mysqld: [ OK ]
5.再次登录后检查端口已修改为’3506’.
root@test etc]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.
