mysql更改端口

修改/etc/my.cnf

添加port=3308

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

然后重启mysql

如果你开启了selinux，mysql会无法启动，你会在日志中看到以下错误

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

[ERROR] Do you already have another mysqld server running on port: 3308

那么，你需要关掉selinux，不想重启服务器，而关掉selinux，使用以下命令

/usr/sbin/setenforce 0

修改linux下mysql端口时候报错：

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

需要修改： vi /etc/selinux/config

SELINUX=disabled

然后重启服务器即可
