yum 安装 mysql

1. yum --releasever=6 list installed mysql*      查看以安装的mysql
2. yum --releasever=6 list mysql*    查看可安装的mysql
3. yum --releasever=6 install mysql-sever
4. yum --releasever=6 linstall mysql-devel
5. mysql配置文件/etc/my.cnf中加入character-set-server=utf8
   
6. 启动MySQL ：service mysqld start
   
7. mysqladmin -u root password 1234  设置root密码
   
8. 远程访问：mysql增加权限：mysql库中的user表新增一条记录host为“%”，user为“root”。

   insert into user(host,user) values('%','root');

   
   

   
   

9. 上一步不起作用的话（登录MySQL之后）：

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '1234' WITH GRANT OPTION;

   
   

   
   

10. 停止MySQL ：service mysqld stop
    
11. 再启动
12. 备注：忘记密码

    service mysqld stop
    mysqld_safe --user=root --skip-grant-tables
    mysql -u root
    use mysql
    update user set password=password("new_pass") where user="root";
    flush privileges;

    
    

    
    

13. 卸载MySQL

    yum --releasever=6 remove mysql*
    查看残留：whereis mysql
    删除mysql目录：rm –rf /usr/lib64/mysql
    删除相关文件：rm –rf /usr/my.cnf
                rm -rf /root/.mysql_sercret 
                rm -rf /var/lib/mysql
