这个报错 其实是很表面的 今天又遇到了
内存太小问题
问题来了
Starting MySQL.. ERROR! The server quit without updating PID file (/data/apps/mysql/data/centos7vps.pid).
原因和解决办法
本质原因: 查看 errlog 171107 12:04:13 mysqld_safe Starting mysqld daemon with databases from /data/apps/mysql/data 2017-11-07 12:04:14 0 [Warning] 'THREAD_CONCURRENCY' is deprecated and will be removed in a future release. 2017-11-07 12:04:14 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

解决办法
应该是内存不够 因为我的ram 才1G 这样就好了 innodb_buffer_pool_size = 500M 当然如果你内存大的 可以这样的 innodb_buffer_pool_size = 1G #innodb_buffer_pool_size = 2G
配置文件问题
问题来了
还是那个报错 查看 err log 其实也没什么 问题,那为什么 在qclud上是可以运行的呢 一开始觉得应该是机器问题,而不是打包的rpm包问题 有点新东西 pid file * ended rpm -ivh ops_mysql_rhel7-5.6.32-1.4.x86_64.rpm 准备中... ################################# [100%] 正在升级/安装... 1:ops_mysql_rhel7-5.6.32-1.4 ################################# [100%] Installing MySQL system tables...2017-11-09 08:36:06 0 [Warning] 'THREAD_CONCURRENCY' is deprecated and will be removed in a future release. 2017-11-09 08:36:06 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

The server quit without updating PID file (/data/centos7.pid). /data/apps/mysql/bin/mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
原因和解决办法
期间相看了 所有err log 到处google 也没搞完 忙了一下午呀 最后是想起系统自带的最简单的mysql 配置文件 于是
[root@centos7 intl-3.0.0]# cat /etc/my.cnf [mysqld] datadir = /data/apps/mysql/data socket=/tmp/mysql.sock # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Settings user and group are ignored when systemd is used. # If you need to run mysqld under a different user or group, # customize your systemd unit file for mariadb according to the # instructions in http://fedoraproject.org/wiki/Systemd [mysqld_safe] log-error=/data/logs/mysql/mysqld-error.log pid-file=/data/apps/mysql/data/centos7vps.pid # # include all files from the config directory !includedir /etc/my.cnf.d
然后就启动成功了 我的天呀 后来 mysql rpm打包直接作了mv /etc/my.cnf 动作了
