MySQL学习6_ERROR! MySQL server PID file could not be found!解决方法

第一种：

可能是硬盘满了，清理下垃圾文件。

/etc/init.d/mysql start无法启动MySQL错误信息如下：

ERROR! MySQL server PID file could not be found!

Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/var/AYXXXXXXXXXXX.pid).

完整日志信息如下：

启动会报错Starting MySQL.. ERROR! The server quit without updating PID file (/var/local/mysql/var/AYxxxxxxx.pid)原因是因为 mysql-bin.0000*的文件占满系统盘，磁盘空间不足导致无法写入。

解决方法：

1：删除所有mysql-bin.0000*日志文件全部rm掉

2：修改在my.cnf 文件，找到 log-bin=mysql-bin 将其启注释掉，以后就不会产生2进制的mysql-bin.0000*的日志文件

第二种：

进程卡死

[root@centos var]# service mysqld stop

MySQL manager or server PID file could not be found! [FAILED]

解决办法：

首先查看一下进程

[root@irxpert-test /]# ps aux |grep mysq*

root 10274 0.0 0.0 68160 1336
? S 13:43 0:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/irxpert-test.pid

mysql 10353 0.0 1.0 344360 39464 ? Sl 13:43 0:00
/usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/irxpert-test.err --pid-file=/var/lib/mysql/irxpert-test.pid

root 11884 0.0 0.0 63384 760 pts/1 S+ 15:44 0:00 grep mysq*

如果看到上面的内容，那说明，Mysql的进程卡死了，这时用就要把这些卡死的进程都关闭

[root@centos mysql]# kill 10274

[root@centos mysql]# kill 10353

启动Mysql就ok了

[root@centos mysql]# service mysql start

Starting MySQL. [ OK ]

第三种：

是修改过my.cnf配置出错引起 执行命令：vi /etc/my.cnf 修改内容：

# The MySQL server

　　　 [mysqld]

　　　 port　　　= 3306

　　　socket　 = /var/lib/mysql/mysql.sock

在执行第二种命令，OK
