linux 修改mysql端口

mysql更改端口
修改/etc/my.cnf
添加port=3399
修改后如下
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
port=3308
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
default-character-set=utf8
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

修改完成后重启mysql

[root@mysql ~]# service mysql restart

错误解决:

[ERROR] Can't start server: Bind on TCP/IP port: Permission denied
[ERROR] Do you already have another mysqld server running on port: 3308

关闭selinux

/usr/sbin/setenforce 0

修改l端口报错解决：

Can't start server: Bind on TCP/IP port: Permission denied

修改： vi /etc/selinux/config

SELINUX=disabled

重启服务器即可
