Hi

Which files i must check for kernel/system mysql and php and nginx limits?

Thanks

Log limits or your mean which config files for system limits ?

For system limits
Code:
/etc/sysctl.conf (only editing on non-OpenVZ servers)
/etc/security/limits.conf
/etc/security/limits.d/90-nproc.conf
for config files

Nginx is at /usr/local/nginx/conf/nginx.conf

PHP-FPM you have PHP include file at /usr/local/nginx/conf/php.conf accessed via command shortcut = phpinc and php-fpm.conf at /usr/local/etc/php-fpm.conf accessed via command shortcut = fpmconf

MySQL at /etc/my.cnf accessed via command shortcut = mycnf

For other command shortcuts and their paths check FAQ 16 at http://centminmod.com/faq.html

Oh for log files FAQ 19 at http://centminmod.com/faq.html
Where are log files located ?

Some of Centmin Mod's installed software will have their own access and error logs which maybe useful for diagnosing errors or give info, notes, or warning notices.

Note: There's no support provided by me for diagnosing such errors which may occur for various reasons including misconfiguration of installed php/mysql scripts or applications.

In SSH2 telnet you can use tail command to view the last X number of lines in the file.

For example for viewing last 10 lines in the file for:

For Nginx access and error logs:
Code:
tail -10 /usr/local/nginx/logs/access.log
tail -10 /usr/local/nginx/logs/error.log
For specific domainname.com access and error log:
Code:
tail -10 /home/nginx/domains/domainname.com/log/access.log
tail -10 /home/nginx/domains/domainname.com/log/error.log
For other system error logs located at /var/log:

list /var/log files in ascending time order so the most recently modified files are at the bottom
Code:
ls -lhrt /var/log
