Apache :: Multiple Backend Ports For One Instance
Jun 16, 2014
I inherited an Apache HTTP instance from a colleague. That's why I'm not deep into that stuff. My current scenario is the following: We are running several backend instances which are published to the internet via Apache HTTP Server which is configured as Reverse Proxy (RP). In the past there was only one port and one protocol to handle by the Apache HTTP (RP).
Now I have the following need. There has to be published a Web Service from one instance using two Ports with two protocols (HTTP and HTTPs). I'm not sure how to solve that need.
A solution I tried already was to change and add the variable DEF_BACKEND_PORT to DEF_BACKEND_PORT_1 and DEF_BACKEND_PORT_2 but it didn't worked.

I am a beginner with Apache web server. Is it possible to fix the Apache instance login with httpd.conf ? I use proxypas :
</Location>
ProxyPass /test09 http://192.168.0.10:5109/test.ts max=1000 ttl=120 retry=0
<Location /test09>
AuthType Basic
AuthName "Password Required"
AuthUserFile "C:Usersusers.txt"
Require valid-user
</Location>
I need user can log in only once when downloading file ( I want to protect with a simultaneous download ) !
Apache is running on Windows.

Currently i am trying to install an Apache 2.4.3 as a caching reverse proxy. I would like to use memcached as my cache backend. I figured out there is a mod_socache_memcache, which from my understanding, should do exactly that(in combination with mod_cache_socache). So i compiled mod_cache_socache from trunk, loaded mod_cache, mod_cache_socache and mod_socache_memcache, but now i am stuck with the configuration. Here is what i tried:
LoadModule socache_memcache_module modules/mod_cache.so
LoadModule mod_cache_socache modules/mod_cache_socache.so
LoadModule socache_memcache_module modules/mod_socache_memcache.so
[code]....
where do i configure the path to my memcached instance? The reason for memcached as chaching backend, is that the machine is a windows machine, and from my understanding mod_cache_disk is not as efficient on a NTFS filesystem as it is on EXT3/4.
Another reason is, that later on there should be a possibility to put a second Reverse Proxy machine which shares the cache with the first one by using the same memcached instance (is that possible at all?).

Depending on where u are at on my site (documents pages, training, main root, etc.) will depend on which type of background, footer, header and the like you'll get. Now I was thinking. Is there a way to have multiple error messages for more then one page depending on where you are at on a site? Right now it's intranet site and a modded snitz forum. What is the code and were does it go and in which apache conf file(s) does it go in?

I've read that all ethernet switches in a MST Region need the same Name, Revision number, and list of member vlans for each Instance. So what happens when you need to change the range of VLANs in a MSTI ? Let's say that you need to add a range of vlans to an instance that spans 20 switches? How would you do that?

I was just wondering what switch everyone would recommend for running a back-end network. We plan to push mainly backup and management traffic over this network. The idea is to have an NAS box connected at 1GBit/sec and all of the servers at 100Mbit/sec backing up to that.
We currently use Cisco Catalyst 2960's to connect the servers to the front-end so it would make sense to use 2960G's for the back-end to keep the overall management of things simplified. There is of course quite a big price difference between a standard 2960 and a 2960G.

Can mod_security perform a payload inspection in a secure reverse proxy?
The traffic to the reverse proxy is via https and is "reverse proxied" to a https backend portal.

Apache keeps stopping. MULTIPLE times per day! There is no logic to when it dies. But about every 2 hours.
Load stays below .30 and there is free memory available.
This is on a VPS machine. None of the other VPS's are having an issue. Just this one.
Centos release 5.3 (Final)
Apache/2.2.3
Here is what is in the httpd.conf file. I realize the numbers are way too high, but just trying to get this issue to go away.
Code:
<IfModule prefork.c>
StartServers 100
MinSpareServers 100
MaxSpareServers 100
ServerLimit 512
MaxClients 512
MaxRequestsPerChild 4000
</IfModule>
<IfModule worker.c>
StartServers 100
MaxClients 500
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 100
</IfModule>
Here is what is in the /var/log/httpd/error_log file before it dies:
Code:
[Wed Jul 01 18:06:32 2009] [info] server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers), spawning 8 children, there are 98 idle, and 108 total children

Our servers has been updated recently and my site is not working properly. It was working before the server change. When I click on the links, it doesn't update correctly, instead it gets the last cached data. I have to refresh each link for it to update which shouldn't be the case. I'm a front-end and have no access to servers. Could this be server-related?

I very much like the "readme.txt" that Apache appends to the directory listings. That is, when a browser GETs a directory, the text in that file is put underneath the list of files therein.

I am completely new to apache and I had the load balancer set up for a single domain that was working perfectly fine, but when it came to multiple domains i couldn't, for the life of me, figure out what to do.
There is example.com sub.example.com and otherexample.com
I had a single node set up for this but I want to experiment with the balancer. I have scratched Google and I only found broken info which couldn't explain much to me. Here are my domains
<VirtualHost *:80>
DocumentRoot "/var/www/domain.com"
ServerName domain.com
</VirtualHost>
[Code] ....
Any example configuration of the default file.

I must say that I tried a lot of possibilities but my knowledgment in Apache WS is not too much advanced.
Apache Web Server version: 2.2.22
OS: Centos 6 64 bits
Tomcat version: 7.0.57
What I need to achieve is the following:
I have some plain websites defined this way:
<VirtualHost *:80>
ServerAdmin example1@example1.com
DocumentRoot "/opt/sites/example1/"
ServerName example1.com
ErrorLog logs/example1-error_log
CustomLog logs/example1-access_log common

I have my Apache 2.4.9 for Windows with multiple Virtual Hosts, the main one is configure like this:
Code:
NameVirtualHost vhost1.domain.org:80
<VirtualHost vhost1.domain.org:80>
ServerName vhost1.domain.org
DocumentRoot "C:/Apache24/htdocs"
ServerAdmin techsupport@domain.org
# ErrorLog "logs/vhost1.domain.org-error.log"
# CustomLog "logs/vhost1.domain.org-access.log" common
</VirtualHost>
The rest like this:
Code:
NameVirtualHost vhost2.domain.org:80
<VirtualHost vhost2.domain.org:80>
ServerName vhost2.domain.org
DocumentRoot "C:/Apache24/htdocs/vhost2"
ServerAdmin techsupport@domain.org
# ErrorLog "logs/vhost2.domain.org-error.log"
# CustomLog "logs/vhost2.domain.org-access.log" common
</VirtualHost>
There is no *:80 anywhere and still when I go to any vhost it always load the main one.
What else do I need to check?

I'm kinda new to apache and I have the following situation.
I have a vps, on which I have set the following:
WordPress Site A, has it's own VirtualHost and domain
WordPress Site B, has it's own VirtualHost and domain
Canvas LMS (not connected to a domain).
Canvas LMS can add multiple accounts, which may (or may not) be accessed individually using a URL that looks as follows:
{canvas_root}/accounts/{account_id}/
For example : http://....../accounts/4/
I need to add a link to each of WP sites, which points to each site's account on Canvas, such that it appears as .../learning/ folder
For example:
Code:
http://WPSiteA/learning/
http://WPSiteB/learning/
which actually represents
Code:
http://WPSiteA/accounts/4/
http://WPSiteB/accounts/5/
Which in turn represents
Code:
http://{my_vps_ip}/accounts/4/
http://{my_vps_ip}/accounts/5/
respectively
Noticing the following:
I do not want the users to see the /account/4/ , just /learning/
I also want to prevent accessing
Canvas LMS is located beyond the website's DocumentRoot
I want this to work with both HTTP and HTTPS

when I had multiple (at least 5) vhosts set to Apache when it just hanged, this was fixed adding:
Code:
Acceptfilter http none
Acceptfilter https none
To my httpd.conf, but now it's not hanging, it just times out, I get no error, nothing in the error.log file, it just times out.
After doing a refresh, it comes back like nothing happened.

Are there particular version of mysql or apache that are best suited when you want to utilize a multi-core/multi-cpu system? For example, we are currently using apache 1.3 and am not sure if it has the inherent ability to use multiple cpus to its benefit.
Or would the fact that it spawns child processes take advantage as the processes will be spawned on the different CPUs?
