- 如何查看mysql 默认端口号和修改端口号 2015-03-19 17:42:18
- 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 ~]# /etc/init.d/mysqld restart
- Stopping mysqld: [ OK ]
- Starting mysqld: [ OK ]
- 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.

- +---------------+-------+
- | Variable_name | Value |
- +---------------+-------+
- | port | 3506 |
- +---------------+-------+
- 1 row in set (0.00 sec)
- mysql>
- 总结:注意修改的端口不要被占用,而且要有规划,不要轻意的总是调整数据库端口。还有就是安全保障,记得与负责网络的人提前通知,以免端口无法正常使用。
