Please remove pid file manually, then start mysqld.
Given the changes you list above, the first thing I'd check is whether you tried to change the innodb log file size to 256M, but you still have an existing log file with a different size.
If this mismatch in physical file size versus configured file size is detected, Inno DB will assume it can't perform crash recovery, so it will stop itself and that may cause the My SQL to fail to start.

If SElinux is the problem, then you should monitor and make it work (check: My SQL 5.6 and SELinux are arguing) You can also disable it permanently at /etc/sysconfig/selinux changing enforcing to either permissive or disabled.
Description: severals day ago, Cent OS is power off unexpectedly. It is also possible that this binaryor one of the libraries it was linked against is corrupt, improperly built,or misconfigured.This error can also be caused by malfunctioning hardware.This site is a technical reference for various things including mac OS, OSX, Web Hosting, web workflow, CSS and other tech like gems - the site is for my reference and yours - there is nothing like finding the right solution that works.The site is aimed at any level of complexity just containing random technical obstacles and observations that I like to document and refer back to - so I hope that you might benefit too.Please use ''--general_log'/'--general_log_file'' instead. Inno DB: The error means mysqld does not have the access rights to Inno DB: the directory.
