mysql dead but subsys locked 问题

我是先用rpm 安装了mysql,然后又编译安装了一个mysql 后来我把他们都删了，又用rpm 安装，可是还是不行

网上找的两种方法都试过了，还是不行，

方法一

解决办法如下

shell> service mysqld stop

shell> rm -fr /var/lib/mysql/*

shell> rm /var/lock/subsys/mysqld

shell> killall mysqld

shell> service mysqld start

含义如下:

1. 停止MYSQL服务

2. 删除/var/lib/mysql/下的所有文件,我想这些文件可能是MYSQL5.1留下来的.

3. 删除锁定文件

4. 杀死所有mysqld进程

5. 启动MYSQL服务

方法二

1. Obviously the 'ole check the log file for anything nasty

cat /var/log/mysqld.log

2. Stop the service

service mysqld stop

3. Check to see if the service stopped, it might be calling the wrong pid.

ps aux | grep mysql

4. Kill any mysql process that might still be running.

kill -9 ??? ???

5. (CAREFUL) Remove/move/backup any databases from the data directory, only do this step if you need to.

rm -Rf /var/lib/mysql/*

6. Check your global options configuration file, should be similar to stevanbt's initial post.

cat /etc/my.cnf

7. Copy over one of the preconfigured 'sample' server-specific options file. Global (/etc/my.cnf) file has priority over server-specific file, but these have more options in them and have been tuned for a certain role.

cp /usr/share/doc/mysql-server-?.??.??/my-small.cnf /var/lib/mysql

8. Recreate the initial databases, this step is optional as the initscripts will do this anyway.

mysql_install_db

9. Check and set the runlevels for the service.

chkconfig --level 345 mysqld on

chkconfig --list mysqld

10. Start the service.

service mysqld start

11. Check the log file (step 1)

Thats just a basic step through check, most of you have probably already done this.

其实做到step 9问题都已经解决了。
