Optimizing apache by disabling unnessecary modules (mod_ssl etc.)

[ioor]

I'm running on a low memory(256MB) vps and I'm looking to optimize it as much as possible. Since I don't use ssl on any of my sites, is it safe to disable the mod_ssl module in apache and if so how do I do that?

I tried commenting out this in /etc/httpd/conf/httpd.conf:

Include conf/extra/httpd-ssl.conf

but mod_ssl still show up when I run: httpd -l

I've disabled named, dovecot, exim, proftpd and vm-pop3d also, since I don't need them.

I'm also running these module, which of them doesn't directadmin need/use?

  core.c
  mod_authn_file.c
  mod_authn_default.c
  mod_authz_host.c
  mod_authz_groupfile.c
  mod_authz_user.c
  mod_authz_default.c
  mod_auth_basic.c

  mod_negotiation.c
  mod_dir.c
  mod_actions.c
  mod_userdir.c

Hi, I'm also trying to optimize my servers and found the following modules

# httpd -D DUMP_MODULES

I do need mod_ssl, but I think I could disable mod_dav and mod_proxy. What do you think? Any other suggestion for removal?

Thanks!

I supose you are not using these modules on your hosting.
I will be better if you will just read the docs about it, cause you know better what you need.

I dumped Apache on my Hosting, not using it for couple of years, it's really loading the system and it's not working stable on High Loaded servers.

deflate_module is used.
I guess log_confg is also needed.

auth_basic is the one used for HTTP authentication? In that case, it is used as well.

dav_* are not used, so I think I could recompile without them.

include_module is used for SSI, right? I don't think that's being used, but it's a service I'd like to keep providing.

 

[localhost]

These are modules.
You dont need to recompile Apache for this.
Modules - are ment to be loaded without compilation.

But those which appear as static (added when custombuild compiles apache, with --enable-{module}) aren't always loaded when the httpd binary is executed?
