  • mysql修改端口号

    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:
