标签：mysql

a.

1. 首先停止服务/etc/init.d/mysqld stop,在/etc/my.cnf中添加：

   socket=/var/lib/mysql/mysql.sock
   skip-grant-tables
   user=mysql

2. 启动mysql服务，输入mysql登陆

3. mysql> use mysql;
   Reading table information for completion of table and column names
   You can turn off this feature to get a quicker startup with -A

4. Database changed
   mysql> update user set password=password (‘lixi‘) where user=‘root‘;
   Query OK, 3 rows affected (0.02 sec)
   Rows matched: 3  Changed: 3  Warnings: 0

5. mysql> flush privileges;
   Query OK, 0 rows affected (0.01 sec)

6. 修改完后重启mysql然后在以自己修改的密码登陆就ok了

b.源码安装mysql及密码破解

   CentOS release 6.4 (Final)
   Kernel \r on an \m

2. [root@192_168_2_193 ~]# uname -r
