[users@httpd] Restart or Reload after changing MaxClients and ServerLimit
Hi,
I need to increase my httpd server's MaxClients and ServerLimit. Can I
just do a
service httpd reload
to load the new settings?
Or do I need to do a
service httpd restart
to load the new settings?
This is on a production server with active users, so obviously the former
is preferable.
Thanks,
Larry Cohen

http://httpd.apache.org/docs/2.2/mod/mpm_common.html#serverlimit
(resp. #threadlimit) states that: "Any attempts to change this
directive during a restart will be ignored, but MaxClients [resp.
ThreadsPerChild] can be modified during a restart up to the value of
this directive."

Yann.

Thank you. BTW, 2.2 is not outdated. It just what RedHat supports for
RHEL6. We can't go to 2.4 until we go to RHEL7. We on government
contracts are not free to upgrade to the latest and greatest at our whim.
We can only make suggestions, but ultimately the decisions are made by the
people paying our salaries. We only upgraded to RHEL6 about 8 months ago,
so it will be a while before we go to RHEL7.
Thanks for your help. I really appreciate it!

Since you are still using the slightly outdated 2.2, the page
https://httpd.apache.org/docs/2.2/en/mod/mpm_common.html
is the official documentation. Looking at for instance
https://httpd.apache.org/docs/2.2/en/mod/mpm_common.html#threadlimit
and
https://httpd.apache.org/docs/2.2/en/mod/mpm_common.html#serverlimit
there's at least some sort of info about restarts and how the params
relate to each other. But maybe not as easy to grok as it should be.

Hi, I really appreciate your response. What I'd like to know is, how do I
look up this information on my own? I use this mailing list generally as a
last resort when I can't find the answer myself. In the case, I did a lot
of research before I asked my question, but couldn't get a definitive
answer. If you could point me to the documentation that you are using I'd
greatly appreciate it.

Re: [users@httpd] Restart or Reload after changing MaxClients and
ServerLimit
Posted by Rainer Jung <ra...@kippdata.de>.
ServerLimit and ThreadLimit configure the size of an internal structure
which maintains data about processes and threads. This structure is only
created during Apache start, so if you want to change these two params,
you need to stop and start.
ThreadsPerChild and MaxClients can be changed and activates with
"apachectl graceful", no need to restart. Only if ThreadsPerChild needs
to get increased higher than ThreadLimit, or MaxClients/ThreadsPerChild
needs to be increased higher than ServerLimit, you need to adjust these
as well and therefore need a completely new start.
So if you want to reserve some reserve space for ThreadsPerChild or
MaxClients, you should configure ThreadLimit = ThreadsPerChild +
"reserved additional threads" and ServerLimit =
MaxClients/ThreadsPerChild + "reserved additional clients"/ThreadsPerChild.
HTH,
Rainer

Re: [users@httpd] Restart or Reload after changing MaxClients and ServerLimit
Posted by "Cohen, Laurence" <lc...@novetta.com>.
Thanks,
I should have mentioned that I'm running Apache HTTPD 2.2 on a RHEL6.7
system. There it is tied to MaxClients which is getting changed at
restart. I believe, according to this that I need to do a full stop and
start to get this to work.
Thanks for your help!
Larry

Re: [users@httpd] Restart or Reload after changing MaxClients and ServerLimit
Posted by Ben RUBSON <be...@gmail.com>.
Reading the doc, seems that ServerLimit is related to MaxRequestWorkers (which has a default set to 256).

Re: [users@httpd] Restart or Reload after changing MaxClients and ServerLimit
Posted by "Cohen, Laurence" <lc...@novetta.com>.
Hello,
While reloading httpd did increase MaxClients to 400 as specified, it did
not increase ServerLimit to 400 as specified. What is worse is that since
ServerLimit remained at 256, this caused MaxClients to be reduced to 256
since ServerLimit seems to be the hard limit for MaxClients.
Even more frustrating is that when I did a service httpd restart, it not
only did not increase ServerLimit to 400, but it threw an error that the
attempt to increase ServerLimit during a restart was ignored.
Any ideas why I cannot increase the ServerLimit?
Thanks,
Laurence Cohen
