Re: httpd won't start with SQLSRV enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

To be fair, the last time I used the mod_php DSO was in 2007 or so. I would highly recommend to migrate to php-fpm pools instead, and use fcgi to have httpd communicate with php-fpm.

You'll even gain the ability to do proper privilege separation that way, and httpd won't have to wait for php extensions.

As per this comment [1] I can get httpd to start with systemctl if the timeout is extended enough. So now I just need to figure out why having PHP SQLSRV enabled causes so much lag. Thoughts on how to identify the issue?

Next step would be to see if using `apachectl restart` works instead of relying on your distro's init scripts / systemd.

FYI, I posted this question on Server Fault: https://serverfault.com/questions/919326/apache-wont-start-with-systemd

I included in that question the stack traces mentioned in my previous email.

On Mon, Jul 2, 2018 at 2:02 PM James Montalvo <jamesmontalvo3@xxxxxxxxx> wrote:
You're right, running `httpd -X` is not dying and is properly serving web pages. It's just dying when running `systemctl (re)start httpd`. It does not appear to be serving web pages at any point between running `systemctl start httpd` and when it times out three minutes later.

I ran a stack trace on the systemctl command (`strace -ff -o /tmp/st2 -s 5000 systemctl start httpd`) and scanned through the six files generated. I don't see any errors. The last 100~150 lines of all six would be a lot to paste here. I've pasted the output of `systemctl status httpd.service` and `journalctl -xe` below. Should I put all the strace outputs into an email?

Thanks so much for your help!

The last 100 lines of the trace or so should tell you if httpd stopped by itself because of the mod_php issue. In your log, there is no such indication.

Try to capture a test case where:

1) That php extension is loaded
2) httpd stops with httpd -X

If httpd keeps running with -X while that extension is loaded, then there is no issue, and httpd is working fine.

Yes, mod_php. I've run stack traces and didn't see anything stand out. At the bottom of this email is the last couple hundred lines of the output from `strace -o /tmp/st -s 5000 httpd -X`, the last couple lines being when I ctrl-c killed it after several minutes. Do you see anything that I'm missing? I looked through the entire log and didn't see anything, but didn't want to post its entirety here. Thanks!

I'm going to venture that you're using the mod_php DSO here. Please clarify otherwise.

If a mod_php extension prevent httpd from starting normally, I would use strace to get the exact error, first:

strace -o /tmp/outputfile -s 5000 httpd -X or strace -ff -F -s200 -o /tmp/strace.out -p PID

It might be time to look into more modern approaches, such as using php-fpm and fcgi with httpd.

Hi,

This is my first message to this list. I've reviewed your policies, but my apologies if I break rules/conventions. Please don't hesitate to correct me.

I've run into an issue where enabling the PHP SQLSRV extension [1] causes httpd to fail to start. I've documented the issue at length here [2]. The PHP SQLSRV extension does NOT impact general PHP use (command line PHP works fine). Only starting httpd will not work. As [2] says, I'm not really getting any significant error messages, so I'm not sure how to proceed. See sections "journalctl -xe output", "/var/log/secure", and "/var/log/httpd/error_log" for relevant log output. Can anyone help me troubleshoot this? Also, this setup works fine on other servers, and I can't think how this one is different.


Thanks in advance,
James
