Server :: Reverse Proxy - With HTTPD Httpd-2.2.3-29.el5
Jul 30, 2010
We are using this url on our testing box and this ip is reverse proxy IP ( 10.192.64.52)
Without reverse proxy:- URL is working fine.
http://10.192.16.77/akc-qa/arsys/ser...TS000000001430
But with reverse proxy its putting escape [%25] in between %3a
[url]
Is it possible to write a rewrite rule to bypass escape [NE] for this particular URL?

I've been trying to figure out how to set up my Apache 2 running on Ubuntu 9.10 to provide a reverse proxy so I can see my wifi network camera monitoring my dogs and still have access to my family website. First, I followed the suggestions from this thread on Ubuntu forums: [URL]. I set up a similar rule set at the end of my /etc/apache2/sites-available/default, restarted apache -- from which I got a response saying that Apache2 could not determine the server name -- and then tried logging into my server through its ip address. When I tried http://192.168.2.80/dogCam, I just got a 404 error. Here's what I added: (I also tried my domain name, but it also didn't work.)
Code:
<VirtualHost 192.168.2.80:80>
ProxyPass /dogCam/ http://192.168.2.160/
ProxyPassReverse /dogCam/ http://192.168.2.160/
</VirtualHost>
When I looked at many other threads, I get recommendations to have my setup in httpd.conf. But, in both this server and a freshly installed Ubuntu laptop, my httpd.conf file is empty! I tried copying and pasting the recommended contents of the following thread, with the example proxy paths replaced with the ones I needed: [URL]. Straight-forward tutorials don't seem to apply, as Ubuntu has a blank httpd.conf file. I figured out that Ubuntu seems to load its modules by simply adding soft-links to the modules of interest from modules-enabled to modules-available. But, after a full day of trying to figure out what looks to be fairly simple and well-documented, I am at a loss for setting up this reverse proxy or even figuring out where to set ServerName to define my domain name to Apache2 in Ubuntu.

I have an issue with my web server. We are running RedHat Enterprise Linux 3.0 with Apache 2.0 and Tomcat 5.5. The situation has arisen that the httpd sessions never terminate. New connections continue and continue to be created and never die. I have restarted the apache services to reset the connection and have even rebooted the server, however, to no avail. Yes, that does the trick of getting the web sites operational, however, this is not a solution.
I have searched and searched here, www.google.com/linux to no avail. I have looked through the apache.org bug tracker and can't find anything like what I am experiencing. This happened 6 months ago and I got lucky and it stopped, however, the situation has resurfaced. I have reviewed the logs and found nothing that provides any insight.
During the business day, the number of httpd connections continue to grow and I decided to let it see how high it would get before the web sites would crash. That magical number is 203. Now that it is later in the evening and about 2 hours since I restarted the httpd services, I now only have 59 connections. However, I'm fairly certain based upon the traffic on these 2 websites, that in the evening, there aren't many connections after 2000 hours.

When I do " ps aux | grep apache " I can see that apache2 is running. But when I do the same thing for http or httpd there is nothing. I looked for this question in the forums but couldn't find it. I probably don't know just what to look for.I'm using the new Debian Squeeze, and was fooling around heavily with new software installations and modifications, and just noticed all of a sudden that I couldn't get on the internet - so I know I did something but don't know what.I can plug in a thumb drive with a bitnami joomla stack on it and run, " ~/tmp/joomla-1.6.0-0/./ctlscript.sh start "and that gets things going for the joomla stuff (apache, http, mysql, php), but that stuff is pretty self contained and does not effect the browser's attempt to reach the web.

I am using qmail in my office. I am noticing this for more than a month. It is my daily routine to check the cpu utilization using top command and by using top different processes can be viewed. the apache process after 1 or 2 days shows cpu utilization of 100%. There is no affect on the server whatsoever of 100% because mail server has 2 processors of 4 core, i think so that may be the reason. Can any one explain why is this happening. What i do after that is i restart the httpd process and cpu utilization comes to normal. What are the reasons behind this and how to solve this permanently.

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.

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 get the following error while starting apache httpd
Code: httpd: Could not determine the server's fully qualified domain name, using <Server's-ip-address> for ServerName I googled it and have come across the following solutions, all of them involve changing the ServerName setting in httpd.conf:ServerName localhost ServerName www.example.com:80 ServerName <ip-address-of-server> ServerName <hostname-of-machine/FQDN>
I am setting up httpd to be accessed from over a LAN, so i don't have a .com domain name. I am thinking of going with the first option, it seems to be working...

This is not intended to teach you about http.conf and its various options. This guide is intended to help with speeding up your web servers by assisting in protecting them from petty abuse, such as hotlinking and scraping, and by using options that yield better performance in general. The methods used in this guide address general concepts, but the implementations of the methods are completely arbitrary, and are tailored to my needs. Each user may want to make their own modifications to suit their own setup. Again, this is a general guide, meant for instruction purposes only. I will go over each significant section in the file, and explain what it does, and the reasoning for it.
This assumes that you WISH to disable the ability to use .htaccess, and to administrate your websites on the server level. If you have a shared hosting plan then you cannot administrate your server at all, and so some of these sections will not apply to you, but some of them will; the ones that still do, you will place in your .htaccess file, in place of your httpd.conf.
Some of the options in these files are default, and so they may not be explained at all. This thread is more about the non-standard configurations.
Most of these options are standard. Notice that there are extra AddTypes, for things such as .xpi files (firefox plugins, etc), and .ogg video files.
Also take note that we disable the option for .htaccess. This makes a dramatic speed increase. This is because if .htaccess is enabled, then for each request made to your server, apache must look in the directory where the requested file resides for an .htaccess file (it does not matter whether one is there or not, and the lookup is NOT cached, so it much be performed EACH request). If apache finds a file, it must parse it. Then it must look in the parent directory, and in the parent's parent, and so on, until it reaches root (/). This is done for EACH and EVERY request. Disabling .htaccess and administrating your server at the global level will make a dramatic difference on busy servers. On not so busy servers, you may not notice the difference.
Note that we disabled cgi-bin completely. This is because we're running mod_php, so we don't need cgi-bin. If you're not using it, lock it down so that no one else can .
Also note that we used AddOutputFilterByType to make sure that all text files were compressed before being sent across the wire. This saves bandwidth.
Of this section, most of these options cannot be set in .htaccess. Options such as the addtype and addhandler and addencoding CAN be set in .htaccess; the rest are global/sever level only.

I am trying to setup Fedira 12 Linux Apache in my home network. I am able to access the hosted website from inside my home network without any problem. I am facing the problem to access it from outside. At the moment i have connected the Apache directly to DSL modem for testing purpose. I was reading "The ISP may have blocked the HTTP port 80. So check it by connecting the Apache directly to DSL modem." The temporary network connections for testing purpose are as follows..
DSL modem (SIEMENS Speed Stream 4200)-->Fedora 12/Linux Apache Server
I am even unable to PING the real ip (IP for DSL modem).(Firefox gave me error message "Connection Timed out) I have tried to ping it from the internet.I can PING the DSL from Apache without any problem.
1. Why i am even unable to PING the real IP of DSL modem at my home.?
2. Is it possible to run/setup Apache by using this type of DSL modem?
3. DSL modem has real IP. DSL MODEM assigns private IP (192.168.x.x) to Apache. So when a http request form the internet came to DSL modem on port 80, will it forward to Apache automatically.? or i have to made any changes.(I can not see anything in DSL modem to change/modify), OR do I have to use another DSL MODEM/Equipment (router)? This setup is just temporary. The actual design is as follows
DSL MODEM(Speed Stream 4200)-->Fedora 12 Linux ROUTER--->Internal network with DNS/Apache Server

Installed Apache2 on a Debian Lenny system. copied my old /var/www/htnl over to the new system.
Now when I open my browser to my PC I get the index.html under /var/www not /var/www/html.
I have this in my httpd.conf:
Code:
From what I have read, the DocumentRoot should have pointed to /var/www/html overriding /var/www?
If I use "10.1.1.13/html" it works the way it should.

We started hosting some very large content on our site, and the usage patterns in cacti have revealed that the HTTP sessions through our load-balancers drop off dramatically right at midnight.
The logrotate process runs right at midnight, and issues a reload command through the service tool (CentOS 5.5):
Code:
$ cat /etc/logrotate.d/httpd
/data/websites/logs/*_log /var/log/httpd/*log {
missingok
daily
dateext
compress
rotate 7
sharedscripts
postrotate
/sbin/service httpd reload > /dev/null 2>/dev/null || true
endscript
}
Looking at the init script reveals that the reload section is suppose to trigger a HUP of the httpd process:
Code:
reload() {
echo -n $"Reloading $prog: "
if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then
RETVAL=$?
echo $"not reloading due to configuration syntax error"
failure $"not reloading $httpd due to configuration syntax error"
else
killproc -p ${pidfile} $httpd -HUP
RETVAL=$?
fi
echo
}
In which, Apache should reload it's configuration and start the new logfile without breaking current sessions. However that clearly isn't what is going on. I'm tempted to edit the logrotate script to trigger a HUP directly by cat'ing the PID file directly. Is this normal behavior for Apache when signaled with a HUP?
