启动MYSQL出错 Manager of pid-file quit without updating file.

Starting MySQL..... ERROR! Manager of pid-file quit without updating file.

启动MYSQL时发现报错 Starting MySQL. ERROR! Manager of pid-file quit without updating file

尝试方法一：

打开/etc/selinux/config，把SELINUX=enforcing改为SELINUX=disabled后存盘退出重启机器试试

尝试方法二：

确实一般都是my.cnf配置文件的问题/etc/my.cnf来自以下文件：如果你的内存≤64M，则复制/usr/local/share/mysql/my-small.cnf为/etc/my.cnf# This is for a system with little memory (<= 64M) where MySQL is only used# from time to time and it's important that the mysqld daemon# doesn't use much resources.如果内存是128M，则复制/usr/local/share/mysql/my-medium.cnf为/etc/my.cnf# This is for a system with little memory (32M - 64M) where MySQL plays# an important part, or systems up to 128M where MySQL is used together with# other programs (such as a web server)如果内存是512M，则复制/usr/local/share/mysql/my-large.cnf为/etc/my.cnf# This is for a large system with memory = 512M where the system runs mainly# MySQL.如果内存是1-2G，则复制/usr/local/share/mysql/my-huge.cnf为/etc/my.cnf# This is for a large system with memory of 1G-2G where the system runs mainly# MySQL.
