Hardware: Db Servers, Web Servers, File Servers. Cpu, Ram, Disk
Jan 20, 2007I have a lot of questions here so if you can't answer them all I understand. even pointing me somewhere where I could get the answers would be appreciated; hardware sites focusing on server hardware, forums focusing on such, etc.
we plan to have three different types of servers:
- db server (self explanatory. mysql. for forums, mysql driven sites.)
- file server (lots of files around ~2-10MB, consistant 70mbps right now, but we want more room for upgrades. needs a LOT of storage room.)
- web server (lots of php files, but also static things like plain html, images, etc. also includes all misc services for the setup-- dns, etc.)
could I be given a rundown for which hardware each of the three should have? I don't need specifics, even just knowing that more ram is important here while cpu doesn't matter as much, or that the fastest disks available are a must, etc would all be valuable info for me. despite that, I certainly wouldn't mind specific hypothetical hardware configs.
for the database server I'm assuming the more ram the better. not entirely sure about the cpu? also not positive on disks...
for the fileserver, how much ram would be practical or useful? disk io will be an issue I'm because plenty of people will be pulling files at once so the disk needs to read from multiple places. scsi (and even raptors) are not an option as we need 750GB+ of space on a reasonable budget. more ram will take some load of of the disks, but how much is neccessary / reasonable?
for the web server I'm assuming cpu first, then ram, but it'll likely need less ram than the db server?
I'm more lost on the disks than anything. scsi on the fileserver is not an option under any circumstances due to $/GB. for the db & web server I'm willing to pay for scsi if the performance increase really does warrant the extra money, but I'd like to be convinced before shelling it out. if you have benchmarks geared at server hardware when it comes to disks I'd really appreciate it.
also, what's the best way to network these together when colocated? each one with a dual gigabit ethernet port and then the communications go to and from the router?

Load Balancing 2 Web Servers And 2 MySQL Servers
Mar 28, 2008I was wondering if it is possible to cluster 2 web servers and 2 mysql servers with only one server working as load balancer.
I am planning to use LVS (ldirectord and heartbeat).
Let's say I have 3 IPs allocated to the load balancing server.
111.222.111.222 (Main IP)
111.222.111.223 (Web Load Balancing IP)
111.222.111.224 (MySQL Load Balancing IP)
If a connection is made to .223 it would pass the request to one of the web nodes.
If a connection is made to .224 it would pass the request to one of the MySQL nodes.
Is it possible to do this?
If not, can I run, for example, nginx on 223 IP address to provide forward proxy? (Then it would not be able to HA but the main point is to load balance so)
Also, what would be the best way to keep the data same on both web servers? This is a web cluster for a very high traffic forum with a lot of uploads every hour so it has to do real time synchronization. I heard that DRDB is only one way and not two way so I'm not going to be able to use this.
Renting Colocated Servers As Dedicated Servers
Oct 11, 2009I am just colocating servers and managing them myself, and renting services off of them. In the future I would like to start offering dedicated servers as well. I am wondering if many companies do this, or if its more of a general practice to just setup as a reseller? The worst part that comes to mind is thinking of how to do billing for the bandwidth per month. With my setup I would only be offering flat bandwidth packages (like 2TB a month) but even so, I cant think of anyway to automate it so WHMCS knows if they went over, if so, how much, etc.

Backend Switch
Apr 8, 2007I 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.

Apache :: Multiple Backend Ports For One Instance
Jun 16, 2014I 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.
Apache :: Reverse Proxy With Memcached Backend?
Dec 21, 2012Currently 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?).

Name Servers
Aug 6, 2009I have recently purchased new hosting with a new supplier which uses a different kind of control panel - cpanel. So before I transfer our organisations website across I want to spend some time playing.
We purchased our domains with 123 reg and the host we have been using for a while is namesco our new hosting package is with neither of these suppliers.
Before I transfer our primary domain to the new host I'm doing a dummy run with one of our other domains and that's where i've come up with this name servers question.
The new host gave me the name of their 2 name servers.
But when I went to my control panel at 123 reg to change the name servers they were not using namesco name servers they were using 123's.
Do I want to change the name servers to the new name servers or not? I'm a bit confused as i was expecting to see namesco names servers?

Sep 1, 2007I've just ordered my first VPS (unmanaged) and the only thing I'm really concerned about is setting up/using a DNS server.
I think I have 3 options.
1. Set up BIND on my VPS... this doesn't look like much fun and offers no redundancy. I'd prefer not to do this.
2. Outsource the DNS server. I'd like to use a free one if possible [url] looks good... anyone had any experiences?) but suggestions of cheap services are also webcome.
3. Use my registrar's DNS server. I'm using namecheap at the moment. Here's the screen that comes up:

Would that work? And create subdomain.domain.tld?
Finally, I think I'd need to select 'user' at the bottom and enter an MX record. Would this be domain.tld?
