Here's my story: The landlord provides the internet for the house and it goes through a server which has squid installed. Squid in turn seems to block the internal port (or whatever the exact term for that is) for phpmyadmin or webmail in cpanel so I cannot access them.
At my reseller account at Hostgator they said they redirected that port to port80 via mod rewrite and that now works for me. I wonder how I would do the same thing on a dedicated server. I can't see what Hostgator did since it's happening out of my sight somewhere. Otherwise I would just replicate that on my box.
I would like to use cPanel Apache as the backend web server, and Squid cache as the front end http accelerator.
My VPS has two IP addresses, however, I want the httpd acceleration to occur only on one IP.
So far, I have installed squid cache and edited its config file to this:
http_port 74.50.118.189:80 httpd_accel_host localhost httpd_accel_port 80 httpd_accel_single_host on httpd_accel_uses_host_header on acl all src 0.0.0.0/0.0.0.0 http_access allow all
My site has a few subdomains and I would like them to work.
So, what do I do now in the apache config (which I think is here: /etc/httpd/conf/httpd.conf ?)
After having conversation with many WHT members and few other system admins I have not been been to resolve an issue yet.
I have a Basic VPS and squid runs fine on it.
Debian 4 Squid 3
Now the issue is that I have 2 IP allocated to my VPS. But no matter what configuration i have on squid.conf file , no matter what version of Squid i use,I am not able to have the additional Ip on my vps as Outgoing External IP address.
I currently have a site running on 8 servers : 5 web servers (apache2/php5), 2 DB servers (mysql 5), and one front reverse proxy server.
Currently I use apache as the reverse proxy (with mod_proxy of course).
I have it do 3 type of things:
1) serve some static files (the website's static files) directly from the front server. The files are stored in local directories.
2) cache some other static files (user uploaded images and files) on the front server after downloading them once from the backend webservers. This is done via mod_cache.
3) route some requests to specific web servers depending on a subdomain (on the first few letters of the subdomain more precisely). To do this i use rewrite rules like : RewriteCond %{HTTP_HOST}^sub1(.*).domain.com$ RewriteRule ^(.*) http://sub1%1.webserver1.com/$1 [P,L] RewriteCond %{HTTP_HOST}^sub2(.*).domain.com$ RewriteRule ^(.*) http://sub2%1.webserver2.com/$1 [P,L] etc.
My web servers are not in a cluster from this point of view, so it is important that the reverse proxy is able to route requests based on subdomain like this.
Now I have a few weird performance problems on the front server. CPU, hard disk usage and memory usage keep staying at relatively constant (and always low) levels, yet the server load periodically spikes to places anywhere between 4 and 12 during the day. This seems to be mod_cache related (spikes disappear when i disable it) but I can't figure what's happenning, and I'm reading everywhere squid is a better alternative to do reverse proxying.
Only, I don't know if i can do the same as mentionned above with squid. From what I read, I know I can do 2). However I'm not sure if squid is able to serve some files (based on URL patterns) directly from the local file system rather than querying them / caching them locally ? And can squid route the reverse proxy requests to different web servers based on the subdomain in a URL?
We currently have two dedicated servers connected to each other with a crossover cable, and each one also has its own external connection. One is running Server 2k3, one is running CentOS with cPanel. What we want to do is configure the so they can run backups to each other through the crossover cable, saving our bandwidth
On the windows machine we have configured it with a static IP of 192.168.0.1 and subnet of 255.255.255.0. This works fine and the machine is running well, on the cPanel machine, when configuring eth1, like so:
the windows and cpanel machines can talk to each other fine through the crossover cable (pinging 192.168.0.1 + 2) but then the cPanel machine becomes unaccessable externally, i.e. ping requests time out and no websites on it can be hosted untill eth1 is disabled and the server rebooted.
2 of my Cpanel server suddenly came up this error... [url] [url]
I have no problem using [url] [url]
I run /scripts/upcp but it's not helpful
--- how do i solve this problem? ---

Could anyone with server geekish skills tell me what may be the problem here might be (I should mention that their annoying support contact form uses the same script hence I can't even get in touch)? What's that ipcop thing about? Do they have some program at the server level filtering IP and mine is no good or what?
I'm aware the REMOTE_ADDR revealed in Squid needs to be a legitimate IP address to communicate properly across the internet. But I'd like Squid to use and publically reveal a different IP address than the default system IP address on our proxy servers. Does anyone know if its possible to make the Squid REMOTE_ADDR use a different IP address on the system other than default.
I've defined a different IP address and port for http_port at the top of the squid.conf file. And I can connect to this IP address and Port successfully. But when I run the connection through an IP address checker, or session environment test, it reveals the actual system IP address and not the http_port IP address.
I'm trying to set up a caching squid server to speed up website access. How can I selectively choose to cache certain PHP scripts while ignoring others? I can't seem to get it to work. I've commented out the following lines:
I want to software load balance one of my website using squid. It doesn't look like it is possible with squid 2.5. Squid 2.6 is a upgrade for FC6. I am running FC4 and it cannot be installed with a lot of dependency failures. Has anyone successfully installed Squid 2.6 on FC4?
