MySql修改默认端口的方法

1. 登录mysql

[root@test /]# mysql -u root -p

enter password:

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 ~]#systemctl restart mysqld

5.再次登录后检查端口已修改为’3506’.

[root@test etc]# mysql -u root -p

enter password:
