[SOLVED] Setting up custom logging for access, error, and ssl with Apache on CentOS 7

witchkinkofangmar · 07-29-2019, 11:03 AM

This is my current setup that is working on Server version: Apache/2.4.6 (CentOS):

Code:

#Custom Logs
LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost
CustomLog /logs/sitename/access_log comonvhost
ErrorLog /logs/sitename/error_log

I haven't been able to find and confim if two CustomLog directives will work in a virtualhost config. Some say yes, some say no. I would like to get the ssl logs to write to a different location as well.

Code:

#Custom Logs
LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost
CustomLog /logs/sitename/access_log comonvhost
CustomLog /logs/sitename/ssl_access_log comonvhost
ErrorLog /logs/sitename/error_log

I don't get any errors when doing a apachectl configtest

We set up a different log file for each virtual host. Works just fine. Simply set

Code:

ErrorLog logs/domainname-error_log
CustomLog logs/domainname-access_log combined

(where domainname reflects the ServerName), in each VirtualHost container,

You could also do what you propose and have a sub-directory for each domain, but I think that would be unwieldy. Naming the log files per domain works well enough.

You could even point all domains to the same log files...but that would be VERY confusing should you need to troubleshoot a specific domain, so I say don't do that!

You should use one CustomLog directive for the plain http vhost and another one for the ssl vhost.
You may take a look also at the CustomLog format options for logging SSL requests.

Nice, thank you. I was using logrotate to compress and rotate so the directories don't get too big but I think your suggestion is much better:

Code:

/logs/sitename/*  {
    rotate 91
    daily
    compress
    missingok
    notifempty
    sharedscripts
    postrotate
        /usr/bin/killall -HUP httpd
    endscript
}

Code:

ErrorLog logs/domainname-error_log
CustomLog logs/domainname-access_log combined

Also, thanks for the link, that's exactly what I was looking for with ssl logs.
