MySql修改默认端口

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:
