Keep getting PID-errors: systemd[1]: PID file /run/httpd/ not readable (yet?) after start. (even when modules/ is disabled)

About the PHP Installation, mod_mpm_prefork seems not the best choice: I would vote for mod_proxy_handler

If the service httpd don't start, take a look at /var/log/httpd/error_log. If appears this line: -[alert] (EAI 2)Name or service not known: mod_unique_id: unable to find IPv4 address of "myhost" you must uncomment the line: LoadModule unique_id_module. Restart httpd and now it should work. --Nak 17:22, 22 April 2007 (GMT+1)

Using SSL

Could the SSL section be expanded to include how to use .htaccess and mod_rewrite to redirect traffic for certain sections or the whole site? I found apache2-forcing-all-inbound-traffic-to-ssl to be a useful resource in this respect. Corburn 13:58, 23 March 2012 (EDT)

User Directories

Continuing discussion from the main page, you do not have to make your home directory world-readable in order to make your public_html directory available to the web server. To minimize home directory exposure, I generally set the permission for both /home/$USER and /home/$USER/public_html to 0750 and change the group ownership to http. E.g.:

mkdir -p $HOME/public_html
chmod 0750 $HOME $HOME/public_html
chown $USER:http $HOME $HOME/public_html

That way you have given only read (descend into) permission to the web server user for both your home directory and your userdir. David C. Rankin, J.D.,P.E. -- Rankin Law Firm, PLLC (talk) 07:22, 25 August 2015 (UTC)

userdir disable

I think that section need add:

#LoadModule userdir_module modules/

to fully disable userdir.

According to [1]:
"User directory substitution is not active by default in versions 2.1.4 and later. In earlier versions, UserDir public_html was assumed if no UserDir directive was present."
So I think it is safe to just not include the conf. --Lonaowna (talk) 18:20, 23 August 2014 (UTC)

Which MPM to use with php-fpm and mod_proxy_fcgi?

The section about php-fpm and mod_proxy_fcgi does not say which MPM (event, prefork, worker) is optimal for this configuration. If I understand correctly (but I'm not an expert), the default mpm_event_module would be the best choice. It would be good to document this, because users coming from a mod_php / mpm_prefork_module configuration would need to actively switch back to mpm_event_module. --Marcvangend (talk) 09:24, 23 November 2015 (UTC)

The best MPM to use is to be determined by individual benchmarks. But event MPM should be good as a default.

A good start would be to, at least, describe what MPMs are and what their main use is, since the term is used multiple times in the article. Something like:
Apache can be configured to use _one_ of several Multi-Processing Modules (MPMs), which affect performance and the way it allocates resources in response to requests. mpm-prefork: ... mpm-worker: ... mpm-event: ... has a short summary of MPM specifics; but we should put up something more informative. :--Nodiscc (talk) 02:54, 18 November 2017 (UTC)
