mysql端口号修改

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:

Welcome to the MySQL monitor. Commands end with or \g.

Your MySQL connection id is 2

修改文件：my.ini or my.cnf 批量修改3306 替换成你要的端口号即可，保存重启mysql服务在配置文件里添加比如3307[mysqld]port=3307 在你的系统目录下有一个my.ini 文件，

WIN98下在WINDOWS

WINNT在WINNT

WINXP在WINDOWS内容如下[mysqld]basedir=D:/MYSQL

#bind-address=192.168.0.2

datadir=D:/MYSQL/data

language=D:/MYSQL/share/chinese#tmpdir#=#port=3306其中port=3306就是端口了，

将#去掉就行了
