The MySQL installation process starts with a PID ended error that is prompted in mysqld_safe to cause problem handling to start

1. Initialization is not a problem after executing mysqld--initialize--user=mysql

2. When performing Mysqld_safe--user=mysql & startup, the shell prompts the following

   Ps-ef | grep MySQL

   Discover that there is no mysqld process exists and that the MYSQLD process is not successful at all

3. Check the error log for cat Error.log

The following error message was found

The problem is that the system cannot find the UNIX socket file/tmp/mysql/sock

4. This error still occurs after multiple reinitialization. Suspect that the Mysql.sock file that was left behind when the space was full caused the failure to start conflicts with an existing file

Go to the TMP folder to view #ll

A mysql.sock file was found that was incorrectly locked

#rm-RF Mysql.sock.lock

Re-initializes and starts the Mysqld_safe script to log on normally
