The server quit without updating pid dating match
Every once a while, when I update my Free BSD box, the system likes to shutdown my My SQL server.Therefore, I need to start it again after the update is done. During the system upgrade, the OS may disable some of your daemons.After rebooting the computer, the error message is gone.If you have modified your My SQL configuration file, My SQL may not like it few versions after (My SQL is not backward compatibility friendly).This is strongly recommended for production servers. [[email protected] mysql]$  11767 [[email protected] mysql]$ 120502 mysqld_safe Logging to '/usr/local/mysql/data/localhost.localdomain.err'.120502 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data [[email protected] mysql]$ This step-by-step guide is mainly for Free BSD, however the idea is the same for Linux.If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in back to what it was, and remove the new ibdata files Inno DB created in this failed attempt.Inno DB only wrote those files full of zeros, but did not yet use them in any way.
That is just NOT the correct step to solving a problem.Moving the does not fix the real problem it just ignores the real problem.The best tool available for My SQL is the error log and what it can tell you. To put it simply: "The server quit without updating PID file" is equivalent to My SQL could not start because of an error that has been noted in the error log.Today when I tried to start mysql it failed with below error: [[email protected] ~]# /etc/init.d/mysql start Starting My SQL.
The server quit without updating PID file (/var/lib/mysql/testvm.pid).Check that the above file is the right version for this program! 160229 Inno DB: The Inno DB memory heap is disabled 160229 Inno DB: Mutexes and rw_locks use GCC atomic builtins 160229 Inno DB: Compressed tables use zlib 1.2.3 160229 Inno DB: Using Linux native AIO 160229 Inno DB: Initializing buffer pool, size = 128.0M 160229 Inno DB: Completed initialization of buffer pool 160229 Inno DB: highest supported file format is Barracuda.
