mysql修改端口

mysql修改端口

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

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
