    Hi

    I was try to restart the Mariadb 10 and i was got an error about missing pid file and when i check the log i go some info about Aria plugin ...

    Then i restart the server to check it and now i am getting 502 bad gateway :(

    Any ideas how can i fix it?

    I am on the stable 07 version.

    Code:
    fpmstart
Starting php-fpm [14-Aug-2014 05:21:58] NOTICE: PHP message: PHP Fatal error:  PHP Startup: apc_mmap: mkstemp on /tmp/apc/apc.CYV5TP failed: in Unknown on line 0
/etc/init.d/php-fpm: line 64:  6162 Segmentation fault  (core dumped) $php_fpm_BIN $php_opts
    Ok fixed :
    /tmp/apc/ folder was missing but how is this possible by just restarting?

    Thanks

    that is PHP-FPM not MariaDB issue did you reboot server before restart ? Because if your /tmp is mounted on ram disk tmpfs then it could of cleared whatever is in /tmp i.e. /tmp/apc. You should try setting apc to /tmp/apc.XXXXXX instead

    I am using another folder than /tmp as many times i have many thousands of files there daily and i want to avoid one folder with so many files there as it is more easy to use on another folder.....

    If i create a folder and then mount it on ram after restart the folder should exist and APC will work even if the startup command that i use to mount it again in ram after restart don't work or not?

    I wouldn't worry as APC is only one file and that is /tmp/apc.XXXXXX. You'd need to figure out why it's happening, you can do a verbose run of the command to restart php-fpm and see what it says

    Code:
    bash -x /etc/init.d/php-fpm restart
    But you're doing it incorrectly for load APC from ram disk read PHP: Runtime Configuration - Manual

    I didn't understand anything from the link :) noob alert...

    But i was thinking that had the cache in ram it should be faster and if i restart i will lost anyway the cache so it is not a problem to start again from zero...

    basically setting path as /apc.shm.XXXXXX is already using memory based caching instead of file based

    I'd just leave it as /tmp/apc.shm.XXXXXX

    /tmp is already in ram with the default Centminmod installation?
