4.2、密码忘记

4.2.1、修改/etc/my.cnf

 [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql #最重要的下面这一行代码 skip-grant-tables # 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

4.2.2、重启MySql

[root@localhost ~]# service mysqld restart

 [root@localhost ~]# mysql -u root mysql> use mysql; mysql> set password for root@localhost=password('root'); mysql> flush privileges; mysql> exit; [root@localhost ~]# service mysqld restart

4.2.4、修改/etc/my.cnf

[mysqld]datadir=/var/lib/mysqlsocket=/var/lib/mysql/mysql.sockuser=mysql# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.pid

4.3、MySQL登陆

[root@localhost ~]# mysql -u root -p

4.4、MySQL常用命令

 show databases; //查看系统已存在的数据库 use databasesname;   //选择需要使用的数据库 drop database databasename; //删除选定的数据库 exit    //退出数据库的连接 create database test01;    //建立名为test的数据库 show tables;        // 列出当前数据库下的表 其他基本的增删改查使用标准SQL即可

4.5、MySQL开放远程登陆权限

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