CentOS 5 Server :: HTTPD Won't Restart After Update: Mod_proxy_ajp Fails If Mod_proxy Not Loaded
Apr 29, 2010
I have just been told that httpd was not running on my Centos virtual server. It seems that my hosting company rebooted my server 2 days ago and that httpd restart failed due to:
Starting httpd: httpd:
Syntax error on line 213 of /etc/httpd/conf/httpd.conf:
Syntax error on line 2 of /etc/httpd/conf.d/proxy_ajp.conf:
Cannot load /etc/httpd/modules/mod_proxy_ajp.so into server: /etc/httpd/modules/mod_proxy_ajp.so: undefined symbol: proxy_module
I had worked around and forgotten about this some time ago. The problem arose because the most recent httpd update installed proxy_ajp.conf into /etc/httpd/conf.d which was then loaded on restart The trouble is I do not use mod_proxy (I think just to try and get a lean and mean web server) and proxy_ajp.conf does not check if mod_proxy is loaded before it tries to LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
Hence httpd fails to restart. RedHats's bug tracker lists this as an old issue (which was never resolved) [URL] My workaround was to rename proxy_ajp.conf to proxy_ajp.conf.orig so that httpd would start up correctly. However any updates simply reinstall proxy_ajp.conf and so IMO the problem needs to be resolved at source. how to ensure that httpd updates do not bite me in the future? Do I really have to run mod_proxy whether or not I need it?
I installed centos 5.5 and httpd service was working well for the last 2 weeks till yesterday. I restarted server and noted my hosting service were not working. I have tried service httpd restart on the terminal and it dispalys [FAILED]. I updated my machine and and have tried restarting it but it doesn't work. I am new to centos and I dont know how to solve this.
I just upgraded to CentOS 5.6 (been on 5.2 for ages....) and am getting the following error in the apache error_log file:[Sat Jul 02 13:50:25 2011] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)[Sat Jul 02 13:50:25 2011] [error] SSL Library Error: -8187 Security library: invalid argumentsThe notice entry, I can understand, however the SSL error is halting apache from starting. It has been suggested that this might be a package mismatch issue. I'll be more than happy sharing the package list for this box on request.
So this very (for me) important little package fails me once again. But this time it refuses to restart/start
This is the output:
Setting up openssh-server (1:5.3p1:-1) Restarting OpenBSD Secure Shell Server: sshd: failed! /dev/null is not a character device! invoke-rc.d: initscript ssh, action "restart" failed.
[Code].....
The error is within the /etc/init.d/ssh script. ("error")
This is in squeeze so I can only blame my self, but.. This is one of the packages that fair and square should not fail to install/update/start/restart no mather what!
I have a VPS server installed with centos 5.3. The server has directadmin. Probably that when directadmin was installed, the httpd server of choice was apache 2.2.13.
My problem is that i whant to install mod_dav_svn trough yum but without updating the latest version of apache form yum repository. If i exclude the httpd package when doing yum install mod_dav mod_dav_svn i get a dependency error witch say that i nedd httpd-mmn installed. So, my question is, how can i use yum to install mod_dav_svn without updating the httpd.
I have a issue that could get me fired, so I would appreciate your input. My knowledge about linux is limited The company I work for has a Dell Poweredge 6850 that keeps pretty much everything (databases, websites, etc). The server had a Virtual Drive created from 2 Physical Drives. Since the HDD space was getting low, we got a new drive, inserted it, formatted and rebooted the system. But the system now refuses to start, giving an FAILED message, something related to EXT2 partition that cannot be read at /dev/hda1
I have a small problem on my Compaq Evo Centos 5.4 web server. The web server runs just fine, the problem is it fails to restart from a power outage. Simple edit the BIOS. No! For a reason I can't think of the keyboard stops working after a few key strokes following the F10 to enter BIOS setup. Then its a power cycle. If left to BOOT the PC and keyboard are fine. After hearing about viruses which get to the BIOS I will ask can NIX get that far so I can adjust the Power ON?
I neded to make some changes to the httpd.conf file. Afterwards I tried restarting,but it won't restart.It's saying port 80 is already in use. after checking via lsof -i :80 I get this result:
Running CentOS 5 x64 And today my httpd is running very slow and I can't find a fix. Looked all over different forums
When starting httpd I get the message: /var/lock/subsys/httpd': No space left on device I checked that directory above and there is no file called httpd tried rebooting server
Can't do updates too: [root@u15438957 ~]# yum update Loaded plugins: fastestmirror, priorities rpmdb: unable to join the environment
I turned my home PC running Ubuntu 10.04 into a server, and so i am so lost, after reading like a 10-20 different guides and/or official docs, I am totally lost.
All I wanted was to create a custom 404 error page...i read about how people edited .htaccess files to customize error pages, i tried and failed also, editing apache2.conf, I got lost and i dont wanna mess up everything and also, how you're supposed to not touch either of those as its not how it should be done and instead you need to edit httpd.conf and i did and FAILED! again...
Also how do I make it so that I can make subdomain(s) on my site? and wth is a name server and where do I get one?
whats the difference between restarting/stopping apache using 'service httpd restart/stop' and apachectl restart/stop. I know that using 'service httpd restart' is actually a script in /etc/init.d/httpd but what about apachectl?
[root@itsupport ~]# service httpd restart Stopping httpd: [FAILED] Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down Unable to open logs [FAILED] Iam facing the above error when i restart the service httpd

I have just configured CentOS server my new office. This is the first time I am using CentOS.
Whenever I am trying to change the webroot of the httpd server, it usually say "directory doesn't exist". whereas which can't be the case as it is home directory of the user.
To achieve this, what Do I need to do?
The second issue, I am facing that whenever I am adding new directories to public_html folder, it is not accessible. as the error page 404 is shown. I have changed the permissions to 0705 and ownership is also transferred to other user. What else is required to make new directories accessible by the web?
i am running cent 5.1 and would like to upgrade httpd v.2.2.3 to the latest 2.2.11 version provided by apache to resolve some ajp errors i am experiencing.
I searched but did not find any rpms for cent nor did i find any instructions on how to do this.
I'd like to share /usr/share/docs out to my local subnet via httpd so I can read server documentation from my workstation. I've simply done a generic install of httpd and httpd-manual and added this to the bottom of my httpd.conf file:
alias /docs /usr/share/doc <Directory /usr/share/doc> Order deny,allow
We had servers that worked fine for years. After updated them to the latest version of CentOS (5.2 with latest updates), they keeps on hanging when being scanned by PCI Verdors (a Credit Card security standard). Basically, the scan causes httpd process to eat up all memory, and the server becomes unresponsive. Normal operations resume after the scan stops for 5, 10 minutes. Output from top looks like the following:
installed a new centOS 5 server, and after the installation, everything seem to work well but for httpd not running. when i try to issue the restart command i get the following error:
[root@appdev ~]# service httpd restart Stopping httpd: [FAILED] Starting httpd: httpd: Syntax error on line 206 of /etc/httpd/conf/httpd.conf: Cannot load
For the first time in installed and configured centos-ds from this HowTos and from the manuals.It is running nicely but disabled my httpd.Is it not possible to run directory service and httpd in the same machine
I've got a box with a fresh installation of CentOS 5.6, but had several configs copied from an old 4.8 box that I've now got to finish. Most everything seems fine, but I can't get apache running. It reports that it starts up fine, but immediately stops and reports "httpd dead but subsys locked"Most of the advice I've found while searching suggests to just delete the http.pid file and restart, which doesn't help in my case. I did find a few problems where SELinux was restricting httpd from creating or touching certain files (I found reports in /var/log/messages) but I've worked through that.
So the big question here is: /var/log/messages and /var/log/httpd/error_log are now empty, and don't show any more errors when I restart httpd. Does anyone know where else I can look for reporting/logging on what's happening to httpd to cause it to die?
I'm working on setting up a hosted OSS app on a VPS and have a question about doing some proxying. I have Centos 5.5/Apache 2.2 running on 2 VPS's, in different locations, accessible from the net. One of these hosts the app itself, the other will be used as a web portal where the end user will login to auth and then be able to access the app. Now, since I don't wan't access to the app server from the world at large, I want to firewall it and only allow access from the portal machine. So what I think I need to do is set up a reverse proxy with mod_proxy, and then if the end user auths forward them to a specific url on the app server.
So when they connect to [url] and log in I need them to be redirected to app.machine.com/theirdir
So the questions I have are:
1) Can this be done? If so, is mod_proxy the way to do it? Configuring Apache isnt a problem, but I havent worked with mod_proxy.
2) If this does work, will it also work with SSL?
3) I've seen a few small tutorials on the net, but not doing exactly what I want to. They all use the reverse proxy with a public IP connecting to a server with a private IP behind a firewall, while I have public IP's on both ends. From a network standpoint I know this shouldn't matter, but I'm not familiar with mod_proxy's particulars itself.
I've added httpd to runlevels 2-5 using chkconfig, and also double checked it using ntsysv, but it still won't run on startup, even though it works just fine when started manually (using "sudo service httpd start").The results of "chkconfig --list httpd" show it is on for levels 2-5, and I've confirmed the current runlevel to be 3. I've found no errors in the logs (neither Apache's nor the system's), but maybe I'm looking at them wrong...My machine is a VPS (on VMWare) running CentOS 5.5 32bit. For additional information, see the output of getinfo.sh: http://pastebin.centos.org/35570I would greatly appreciate help on this, as it is delaying our NGO from moving servers.
I am running centos 5.4, kernel 2.6.18. Also running httpd (apache2) as a reverse proxy with the following modules mod_ssl mod_cache mod_proxy_*
Recently after updating these modules: mod_ssl x86_64 1:2.2.3-31.el5.centos.2 httpd x86_64 2.2.3-31.el5.centos.2 distcache x86_64 1.4.5-14.1
I am getting wierd errors in the error logs: [Wed Feb 10 15:44:18 2010] [error] (103)Software caused connection abort: cache: error returned while trying to return disk cached data [Wed Feb 10 15:44:45 2010] [error] (103)Software caused connection abort: cache: error returned while trying to return disk cached data [Wed Feb 10 15:44:48 2010] [error] (103)Software caused connection abort: cache: error returned while trying to return disk cached data .....
accidentally I do something wrong with my server and the httpd folder missing and I need it to setup my mail server and anyone can help me what can I do without reinstalling my Cent OS? Here is the error msg :
[root@mydomain etc]# service httpd stop Stopping httpd: [FAILED] [root@mydomain etc]# service httpd restart
I've been trying to make install apache 2.1.8 and php 5.2.3 and work on them. After updating and installing some dependence files, apache and php could both be installed.
Then I tried to configure them. I added the following content to the end of Apache httpd.conf:
Code:
Then I run /path/to/apachectl start, and saw the message:
Quote:
Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
Then I remembered that I didn't include the rewrite module while making install apache. So I removed the 2 lines I just added to httpd.conf.
But, after running /path/to/apachectl stop and start again, I could still see:
Code:
When I use firefox to open http://host_ip:8080/, I could see "It works!". But when I open http://host_ip:8080/hello.php (the file is already under htdocs), firefox said Quote:
Failed to Connect
Why and how to solve it?
I noticed that for some stupid reason, the conf file wasn't updated at all and the 2 erroneous lines were still there.
Basicly just installed a fresh version of Cent OS 5.4 with apache httpd installed automaticly during the installation. The http daemon is running and when navigating to localhost i get the welcome cent os apache page thingy. The problem is when i put an index.html file in /var/http/www then try and navigation to localhost I get a 403 forbidden error.
