Manager of pid file quit without updating fi failed
I am also involved in an electronics rental Startup, and coach technology. It does not exist in nature, nor do the children of men as a whole experience it.I practice public speaking, travel quite a bit and have a big passion in entrepreneurship. Avoiding danger is no safer in the long run than outright exposure. It's always a laugh or three when talking to Jeff and since this was a critical server (high traffic) I thought first to call him to see if he has hit this yet...and in fact he had, however it would be nice to understand the exact details here and how we can prevent this for the common user in the future. Manager of pid-file quit without updating file 2018-8-30日补充说明：pid-file quit without updating file这个错误基本都是配置不当造成的，绝大多数是跟/etc/my.cnf有关系。在出现这个错误后，可以查看mysql的数据目录，也就是datadir下的xx.err文件，xx是用户名，查看该文件底部的最新日志，就可以看到具体的报错项目，有的是启动参数不对，有的是配置文件错误，有的是比如下面这种诡异情况，总结来讲还是要学会看日志排查错误。 1、如图所示，新装的myql启动失败，报错： ERROR!During a recent update using custom build, one of the items was mysql going from 5.1.55 to 5.1.56, not a big update I assumed etc..Not too sure about recreating the file, i tried this and it just removed itself!But these may not solve the issue, I found a clean install of the latest mysql will address the issue by installing all components from the dmg.
It runs all of your website's databases, WHM/Cpanel control panel databases etc. There could be many reasons behind the failure of the service.
After some Googling, I found out that this problem was due to the Inno DB logs.
I deleted ib_logfile0 and ib_logfile1 and I was able to start mysql server without any problems.
Inno DB: If that is the case, please refer to Inno DB: [ERROR] Plugin ‘Inno DB’ init function returned error.
