修改CentOS6.5主机名引起MySQL5.6.35服务问题
本来是心血来潮修改CentOS6.5的主机名
/****** 修改CentOS6.5默认主机名 ******/
、备份系统网络配置文件
[root@localhost ~]# cp /etc/sysconfig/network /etc/sysconfig/network.`date +%Y%m%d.%H%M%S`
、备份系统网络配置文件
[root@localhost ~]# vim /etc/sysconfig/network
修改HOSTNAME为我们想要的名字VMUest 、备份hosts文件
[root@localhost ~]# cp /etc/hosts /etc/hosts.`date +%Y%m%d.%H%M%S`
、修改hosts文件
[root@localhost ~]# vim /etc/hosts
在127.0.0.1后添加主机名VMUest(注意空格) 、修改上面两个文件后，需重启才永久生效。使用hostname可临时生效
[root@localhost ~]# hostname VMUest
我这里没有重启虚拟机，使用命令临时生效。退出后重新登录主机名已更改为VMUest。本以为大功告成，手贱查看下mysql服务状态(之前mysql服务设置为自动启动)
[root@VMUest ~]# whereis mysql
mysql: /usr/bin/mysql /usr/local/mysql
[root@VMUest ~]# cd /usr/local/mysql
[root@VMUest mysql]# ll

[root@VMUest data]# service mysql status
ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql) exists
[root@VMUest data]# service mysql stop
ERROR! MySQL server PID file could not be found!
[root@VMUest data]# service mysql restart
ERROR! MySQL server PID file could not be found!
Starting MySQL.Logging to '/usr/local/mysql/data/VMUest.err'.
.............................................................................................................. ERROR! The server quit without updating PID file (/usr/local/mysql/data/VMUest.pid).
此时还可以操作MySQL数据库(查询数据、创建表格都正常)。搜索关键字"ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql) exists"，给出的解决方案是删除文件/var/lock/subsys/mysql，重新启动如果依旧出错考虑删除pid file。
[root@VMUest data]# rm -f /var/lock/subsys/mysql
[root@VMUest data]# service mysql status
ERROR! MySQL is not running
[root@VMUest data]# service mysql start
Starting MySQL...................................................................................................... ERROR! The server quit without updating PID file (/usr/local/mysql/data/VMUest.pid).
[root@VMUest data]# rm -f localhost.localdomain.pid

到此时才想起去查看错误日志(.err)

关键字"Check that you do not already have another mysqld process using the same InnoDB data or log files"，是否有其他进程使用相同的文件？
#使用ps命令查看是否有mysqld进程在运行
[root@VMUest data]# ps -ef |grep mysql
root : ? :: /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/localhost.localdomain.pid
mysql : ? :: /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/data/localhost.localdomain.err --pid-file=/usr/local/mysql/data/localhost.localdomain.pid --port=
root : pts/ :: grep mysql
#mysqld进程打开了哪些文件：
[root@VMUest data]# lsof -c mysqld |grep localhost
mysqld mysql 1w REG , /usr/local/mysql/data/localhost.localdomain.err
mysqld mysql 2w REG , /usr/local/mysql/data/localhost.localdomain.err
发现有一个2060的进程在运行，并且打开localhost.localdomain.err文件。原以为删除这个文件(rm -f localhost.localdomain.error)会正常，结果删除过程不报错，实际却没删除！于是强制kill掉进程
[root@VMUest data]# kill -
[root@VMUest data]# ps -ef |grep mysql
root : pts/ :: grep mysql
[root@VMUest data]# lsof -c mysqld
[root@VMUest data]# service mysql start
Starting MySQL...... SUCCESS!
重新启动MySQL成功......
总结，如果不修改主机名就不会遇到这种问题，如果修改了主机名之后马上重启服务器也不会出现这种问题。碰巧使用命令生效，然后去查看MySQL的状态，进而掉入各种坑。
[root@VMUest ~]# cat /etc/init.d/mysql |grep hostname
mysqld_pid_file_path=$datadir/`hostname`.pid
其实问题的根源就是使用hostname临时修改主机名，service mysql **会调用文件/etc/init.d/mysql，此文件使用`hostname`会获取修改后的主机名，导致中间的逻辑"异常"(实际MySQL服务一直正常)。吐槽下，测试过程中虚拟机连同宿主机崩掉，强制重启后虚拟机报"锁定文件失败，打不开磁盘或快照所依赖的磁盘"，只需将存放虚拟机系统文件的文件夹中的.lck文件(类似于M33061.lck、M20423.lck、M13879.lck)删除即可。遇到了，纠结下，解决掉。
