can not star Apache web server.

[bsdnewbie999]

Apache webserver won't start when i do

/usr/sbin/apachectl start

I just wait and nothing happens...

[jggimi]

Question #1: What is the value of httpd_flags on this system?

Hint: to obtain the answer, issue the following command. Note that this command will check the results in both rc.conf and rc.conf.local, if you use the latter.

$ grep httpd_flags /etc/rc.conf*

Question #2: Is Apache already running?

Hint: to obtain the answer, issue the following command. No response means that Apache is not running. Processes listed means that Apache is already running.

$ pgrep -lf httpd

[bsdnewbie999]

$ grep httpd_flags /etc/rc.conf*

it returns httpd_flags=NO but then i change it to flags="" and put the line to rc.conf.local and i restart the machine. The service loaded from sendmail until httpd and stops there for long time. I think it cannot start so i Ctrl+ C to cancel it.

Do I need to install apache package from the web? Because i thought apache is included in the default setup.

[jggimi]

OpenBSD includes a secured Apache 1.3, with additional features such as integrated SSL/TLS and DSO.

As you have discovered, this is normally started via rc(8) and configured in rc.conf.local(5). It is described in httpd(8) and discussed in FAQ 10.16.

It appears that this built-in httpd is not working on your system. It appears to hang, rather than start.

There are no bug reports with this symptom, so I begin to suspect your configuration.

Question 3: Have you ever changed, added, or removed any files in /var/www?

Question 4: I'd like to know all about your OS, and your hardware configuration. Rather than ask you eight different questions, and have you try to answer them, please just post your dmesg.

[bsdnewbie999]

I never touch /var/www before. Here's my dmesg

Thank you. I now know:

• You are running 4.4-release on i386 architecture, and without any of the errata patches, as patch#1 is a kernel patch.
• You have 256 MB of RAM defined.
• You are running with APM, and ACPI is disabled.
• You are running the OS from within a VMWare virtual machine.

I don't see anything indicative of a problem, directly, but this information is helpful in two ways:

1. Patch #4 is for httpd. It does not appear to directly apply, as it is related to mod_proxy, which is not enabled by default in /var/www/conf/httpd.conf. Examine the file, and confirm that mod_proxy is commented out. Please consider applying the patch, as well.
2. 256MB may not be sufficient RAM, since you run X (both Fluxbox and KDE have been mentioned by you in other threads, if I recall correctly). If you run out of RAM and swap space, your OS will stop operating properly.

Question 5: What is the size of your swap space?

Hint: to answer this, see the output of:

$ swapctl -lk

Since this appears to be an httpd process hang, and not an OS hang, perhaps you can gather more diagnostic information:

Run top(1) from another console while httpd is started and inoperative. Filter for httpd, and examine any httpd processes shown. Is one or more CPU bound? If not, what is/are the process(es) waiting for?

Diagnostics may be obtained from tools like gdb(1), systrace(1), and ktrace(1), but you do not appear to have the applicable skills or knowledge required to deploy them. We are left with empirical examination using tools like top, systat(1), and vmstat(1).

Please don't hijack your own thread, bsdnewbie. If you need assistance with MySQL:

1. Research deployment and configuration of the database platform on your own, first.
2. Install the packages required.
3. Configure as you require for your application.
4. If you get unanticipated results, research the cause as best you can.
5. If you still need assistance, consider if your trouble is OS, database, or application related.
6. If application related, post your question on the appropriate application support forum or mailing list.
7. If database related, ask your question on the appropriate MySQL forum or mailing list.
8. If OS related, bring your specific question here ... but in a new thread.

[Carpetsmoker]

jggimi, you are the man!

[johnzlly]

Agree,Carpetsmoker.

[bsdnewbie999]

I have downloaded the patch for httpd but i have problem patching it when i do

# patch -p0 < 004_httpd.patch                                                  
Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------

|	make -f Makefile.bsd-wrapper cleandir
|	make -f Makefile.bsd-wrapper depend
|	make -f Makefile.bsd-wrapper

File to patch:

something that confused me:
1. Maybe u think it is stupid quetion but i really don't know what is the File to patch? I have been google it and search in the openbsd faq and i found that there is a number of people don't know about this too besides I didn't found any answer for that..

2. For the File to patch, i tried to put in the httpd.patch file and it failed. So i guess there should be a file in the /usr/src directory but nothing is there..


jggimi,
Here is my swap space and I have set the RAM for OpenBSD virtual machine to 516RAM.

# swapctl -lk
Device      1K-blocks     Used    Avail Capacity  Priority
swap_device    313267        0   313267     0%    0

Still not reading the FAQ eh?

http://www.openbsd.org/faq/faq5.html#BldGetSrc

I'm starting to think this is some elaborate April 1st joke, nobody here is aware of the state of your system.. clearly you like tweaking/changing and testing things without first understanding the repercussions of doing so, you appear to have sufficient amounts of swap and RAM for a typical home server.

Possible problems? defective ram... configuration error... general user error we cannot remotely diagnose.

Sorry for the harshness, but.. it had to be said.

[bsdnewbie999]

I know about cvs in updating the source tree. But I can also update using patches and the faq really didn't mention about the "File to patch:". It does confuse a totally new BSD guy like me.

[BSDfan666]

If you read a little further on the page I linked to, you would have noticed that you can obtain the source from a local mirror..

The source is not installed into /usr/src by default, but it is distributed on both release CD-ROM's and the FTP/HTTP mirrors.. in your case... src.tar.gz is what you're looking for.

Also, that errata patch is only relevant on 64-bit architectures... as mentioned clearly on the 4.4 errata page.

Originally Posted by http://www.openbsd.org/errata44.html#004_httpd

Fix httpd(8)'s mod_proxy module which is broken on 64-bit architectures. Due to the bug this will result in child processes crashing when utilizing proxy rules during an HTTP session.

I gave a short list of other possible causes above.. there is nothing we can do without a little more information from you.

When confronted with confusion, go to the tools known to provide information.

• What does the manpage for patch(1) state?
  

  DESCRIPTION
       patch will take a patch file containing any of the four forms of differ-
       ence listing produced by the diff(1) program and apply those differences
       to an original file, producing a patched version.  If patchfile is omit-
       ted, or is a hyphen, the patch will be read from the standard input.

• On the patches page:
  
  http://openbsd.org/errata44.html
  
  There is a link which points to a text page stating (& jggimi has already mentioned this...):
  

  Apply by doing:
  	cd /usr/src
  	patch -p0 < 004_httpd.patch

• More information on patching can be found in Section 10.15 of the FAQ:
  
  http://openbsd.org/faq/faq10.html#Patches
• The remaining question is how did you obtain the patch file itself? The patches file, 4.4.tar.gz, can be found on the project's main ftp site at pub/OpenBSD/patches/4.4.tar.gz.

• So i guess there should be a file in the /usr/src directory but nothing is there..

  /usr/src will only have source code present if you have correctly followed the instructions of Section 5.3.3 from the FAQ:
  
  http://openbsd.org/faq/faq5.html#BldGetSrc
  
  Source code is not installed by default during installation.

To become proficient & productive with OpenBSD, you need to learn to use the tools available which includes understanding the documentation. Guessing will only get you into trouble, & by now, you should be aware of this consequence.

[jggimi]

• OpenBSD is source-code maintained. The adminstrator is expected to know and understand this, and be capable of source code maintenance.
• Source code is not included during any installation. The administrator -- this means you -- is expected to obtain this in a separate step, as outlined in FAQ 5.

Maybe u think it is stupid quetion but i really don't know what is the File to patch?

If you had taken the time to read the patch, you would see it patches multiple files:

usr.sbin/httpd/src/ap/ap_hook.c
usr.sbin/httpd/src/modules/proxy/proxy_http.c

These files exist in the source code, which you must manually obtain and place in /usr/src, per FAQ 5.

Stupid question? No. But it is a question which highlights what appears to be a continual intentional ignorance. It appears to be a complete indifference or unwillingness to learn, to me. If so, I don't think this OS is a good one for you, as it requires a willingness to learn ... unless you have the willingness to hire professional adminstrative services instead.

[bsdnewbie999]

Now i managed to apply the patch. But my httpd still hangs.

[jggimi]

Above, I said:

It apparently did not fix your problem, as expected. But I'd also written:

                                   Not Found

   The requested URL /server-status was not found on this server.

and i tried top again, it shows

[johnzlly]

It's normal.When there is someone connecting,it'll fork a child process to take the socket.

[jggimi]

Usually, httpd runs as a pool of processes. It does not appear that the application has gotten that far, but you cannot be sure unless you follow my recommendation. I'll highlight it, once more, because you've missed it twice now.

It is likely that this won't show anything of value, of course. But we will never know unless you try it and report.

Should you bother to read httpd(8), you will see that there are a few things you could try that would be easier than posting here.

Example: -X. Does it produce any console output? If there is an error, it might show here.
Example: -T/-t. Do both produce confirmation of a valid httpd.conf file?
Example; -V/-v. Do both produce valid output?

All this time, httpd just might have been reporting problems in /var/www/logs. It is possible that the reason for the hang is in /var/www/logs/error_log.
