we have an ubuntu server (10.04 LTS) with apache2 (2.2.9) and mod_proxy + proxy_balancer enabled.Reverse proxy works greatly, but I can't get load balancing working. Apache connect always to first member.
My configuration is as follow:
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Proxy balancer://test>
[Code]...
A first server with apache2 installed and configured as reverse proxy, that works great, with this version:
That works mostly, but fail with an oma (outlook mobile access) redirection
It works for all reverse sites hosted, but when we try to connect to oma using a nokia phone, it fails.
I can see in access.log that it hangs on FolderSync istance.
I've used wireshark to sniff packets, and in oma server I can see only three way handshaking coming...
My doubt is: when I'll upgrade working server, also it will not work anymore...
Configurations are the same (I've copied /etc/apache2 folder from running one to new one).

how to do Load Balancing & Failover With Dual/ Multi WAN on Linux proxy server.
I have a 10.04 32-bit virtual ubuntu server. I am trying to figure out how to setup load balancing. Here is how I planned out to do it, I need direction for what software I should use.
--Internet(1.2.3.4)
--Router
---Load Balancing Server (192.168.1.30), port 80, public as in port forwarded Load balancer sends traffic to either web server
---Web Server 1 (192.168.1.100)
---Web Server 2 (192.168.1.101)
I heard I should use rsync to keep the files concurrent, at this point rsync is the least of my worries. I need to know what load balancer I should use I have tried and failed with crossroads(xr), and balance. I can't seem to find a modern tutorial for either system. I looked at linux virtual server but that is like 5 years ahead of my current knowledge.
I'm a newbie on Ubuntu, I have a problem with squid proxy. I'd like to configure a system, include:
- a server is named ProxyServer that is installed Squid proxy.
- three servers, are named FTPServer01, FTPServer02, FTPServer03. each server is installed vsftpd.
- Clients are installed Filezilla to up/download resource.
All servers are managed by IP address. When a client request a resource, client connect to ProxyServer, this ProxyServer will switch to one of Ftp servers. I do not know how to configure the squid's config file to setup them.
I am about to build a server cluster with mysql-cluster and a couple of apache webservers. I have found lots of tutorials regarding the setup of haproxy, but i have the option to get a pretty affordable barracuda load balancer. Now, i am kinda new at this. But my main questions are.. Can the load balancer also serve for the database? Is it a straightforward configuration?
View 1 Replies View RelatedI have a reverse proxy set up with squid. I'm going to try and explain what it's doing and I apologize for it being confusing, I'll do the best I can to describe my problem. First, it's for our phone system. We run a ShoreTel Voip system. The owner has decided he wants me to setup MCM (Mobile Call Manager), which from what I can see is an under developed, and almost impossible to get help with Shoretel software. But he's convinced he needs it for his Iphone. It's supposed to, in a nutshell, turn his Iphone into his work phone with all the advantages and doodads that come with it. Apparently, "they have an app for that". On the server side, I need to setup a reverse proxy back into the network on our phone server. Simple enough, I did this with squid. I used the following lines:
Code:
http_port 80 accel defaultsite=172.17.137.7
cache_peer http://172.17.137.7 parent 80 0 no-query originserver name=myAccel
acl our_sites dstdomain http://172.17.137.7
[code]....
Code:
always_direct allow all It most definitely is allowing traffic back to the phone server, the problem is, it hands out my internal server address to the outside client. So for instance, if I connect to the outside routable address with my phone, it will immediately change the url to http://172.17.137.7 which is the inside nat address of my phone server. Which of course doesn't work, since I couldn't browse to that address from the outside. It does however work from the inside of the network, obviously because 172.17.137.7 is accessible from the inside.
the apche2.conf and vhost file I gave the link are the machine on LAN when site is actually hosted.When some one from internet access the site then I expect a log of IP in access.log instead of which I see the IP of machine which is working as Reverse Proxy server for all such requests.What mistake did I do above.

|--------------192.168.1.5

Except one all websites are running properly and being redirected to their respective domains.
Following is the configuration which I used for each site define on server A a vhost file which contains following
Code:
# ProxyPass / http://<Ip of Server>
# ProxyPassReverse / http://<Ip of Server>
So if I have 5 websites then I have 5 vhost file on the gateway in above diagram A and in each of those file as above root of site is redirected to internal IP. 4 of them are running properly. The fifth website is running on port 8080:/keyword. So in its vhost file on gateway I defined
Code:
# ProxyPass / http://<Ip of Server>:8080/keyword
# ProxyPassReverse / http://<Ip of Server>:8080/keyword
I can see on Lan http://<Ip of Server>:8080/keyword but when from internet I try to see:
http://site5.abc.com
I get redirected to a page is https://site5.abc.com:8443/ and it says
Code:
The webpage at https://site5.abc.com:8443/ might be temporarily down or it may have moved permanently to a new web address. The site5.abc.com has a requirement to be run at port 8080 internally and it is not a Ubuntu server.(Red Hat based server). While rest all are Ubuntu servers including gateway A.
I have a php app set up in the default virtualhost, and want to add a Grails app. The grails app runs on [URL] and I want to configure apache2 to proxy that folder to Jetty using mod_proxy.

[Sun Mar 21 00:14:56 2010] [warn] proxy: No protocol handler was valid for the URL /mailscan. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule. My apache2.conf contains no LoadModule lines, and a2enmod says it's already enabled. Does Ubuntu Desktop (Karmic) use the DSO versions of modules, or did I miss something else? I'm aware I should also use mod_proxy_html to make sure only the "portless" version of the address is outputted, but I can fix that later!

My apache and wordpress were running fine till this morning. I ran updates via webmin,though I wasn't sure what those updates were for.
Then when I tried to access mysite.com, index.php downloads instead of opening.
I tried some troubleshooting and followed a form where it was advised to enable mod php5, so I did a2enmod php5 and tried to restart apache. Since I get this error Cannot load /usr/lib/apache2/modules/libphp5.so into server.
I have suse10 64 bit installed. I am setting up a svn server on it. After installation and adding the modules ,while reloading the apache2 it's throwing the error as: HTML Code: httpd2-prefork: Syntax error on line 113 of /etc/apache2/httpd.conf: Syntax error on line 31 of /etc/apache2/sysconfig.d/loadmodule.conf: Cannot load /usr/lib64/apache2/mod_dav_svn.so into server: /usr/lib64/libsvn_subr-1.so.0: undefined symbol: apr_memcache_add_server

I'm folding and I need it to only run on 6 cores instead of 8, and I have it set to do that but Ubuntu decides to bounce the load around the 2 extra cores as well, hurting my performance. Is there a way to disable it or set it to work only on 6 specific cores?

There are iptables rules for balancing and forwarding:
Code: Select alliptables -t mangle -A PREROUTING -j CONNMARK --restore-mark
iptables -t mangle -A PREROUTING -m mark ! --mark 0 -j ACCEPT
iptables -t mangle -A PREROUTING -j MARK --set-mark 10
iptables -t mangle -A PREROUTING -m statistic --mode random --probability 0.5 -j MARK --set-mark 20
iptables -t mangle -A PREROUTING -i $wan1 -j MARK --set-mark 10
[Code] .....
There are iproute2 rules:
Code: Select allip route add 172.20.0.0/24 dev eth0 src 172.20.0.150 table WAN1
ip route add default via 172.20.0.254 table WAN1
ip route add 192.168.0.0/24 dev eth1 src 192.168.0.150 table WAN2
ip route add default via 192.168.0.254 table WAN2
[Code] ....
The packets marked as 20, theoretically routed via table WAN2 via 192.168.0.254, are lost.
The WAN2 gateway is working if I set as default without balancing.
I disabled the rp_filter module on all interfaces and I installed xtables-addons-dkms.
I also try this but I had trouble with forwarded connexions.
I am having a problem getting ISP load balancing working. Currently I can get only one side or the other working. I have been researching and reading Forum threads and other related posts on the subject.. I have read Howto's and lartc.org/howto.

So I would like to have two internet links active per time and have one LAN consuming from the two links. I have seen the phrase Load Balancing all over the place but they all show their examples using ethernet and static IP's. My providers give DHCP ip addresses so is there anything I need to know and can anyone point me in the direction of some tutorial or howto i can follow to do this?

This should work seamlessly with any application. How I can achieve it using any combination of Advance routing, VLAN, iptables LINUX.

I already setup the load balancer and two servers behind it with this kind of topology
Code:
_ Server 1
request -> DIRECTOR /
\_
Server 2
[code]....
The problem is when I try to hit the 192.168.1.1, it sometimes give me a HTTP 200 and sometimes it will timed out. I hit it using lynx -dump. It should return "Hello world!" if success. But if we hit it directly to 192.168.1.2:80 and 192.168.1.3:80, it will return HTTP 200 which means no error and no timeout. Since the Server 1 is the same as Server 2 in configuration, are there somethings I missed here?
Another information is that I set the director using round robin algorithm, so everytime a successful hit returned from server 1, the next one is surely heading to Server 2 right? Based on the Apache's access log, I also knew that the timed out occured only when it is the Server 2's turn to handle the request. Aside from the same httpd.conf and the same httpd version are there any things in the system level, kernel level that should be the same between those two servers?
I am using centos with two physical LAN cards. Some times one of our internet link goes down so the entire network stop. Now there are two different ISP internet lines coming into a single computer in their respactive lan cards for load balancing.
Kindly guide me that how can I enable Load Balancing in my Linux Box.
If one ISP goes down the load balancing server will use teh second one and vice virsa.
What is a Reverse Proxy? And what is the use of implementing a Reverse Proxy???

View 2 Replies View RelatedA little background: CCNA and A+ I have preformed this task on Cisco routers Linux for 5+ years, mostly with Debian (mostly casual, a few production situations) I need to setup a linux box with Load Balancing over a cable line 8mb down, 1mb up connection and a T1 line. If this isn't possible, at the very least I need Failover (which I have admittedly not researched as fully.) I know Failover is possible, but I would really love to double my upload bandwidth as we host a small website here. Is load balancing over uneven connections possible on Debian?
Side question: If I host a website, when users connect and get responses over 2 Public IP's, what would be the reaction on the users side? Would it get filtered and or blocked by a firewall?
