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
然后重啟mysql
如果你開啟了selinux，mysql會無法啟動，你會在日志中看到以下錯誤
[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，你需要關掉selinux，不想重啟服務器，而關掉selinux，使用以下命令
/usr/sbin/setenforce 0
修改linux下mysql端口時候報錯：
Can't start server: Bind on TCP/IP port: Permission denied
需要修改： vi /etc/selinux/config
SELINUX=disabled
然后重啟服務器即可
