I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts
I 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?
We send mail to another servers but we cant recieve mails another servers. We can't recieve with webmail and outlook.
I look logs but there is no error and our ip is not in blacklist.

I 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.
I 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.

How do I check in shell that this is indeed the case?
I read in some places that "top" and "free -m" and such can help.
But these gave me way more than 512.
Here is the output from my "free -m". Total shows here 3886 MBs of MEM??? That is almost 4 Gigs. Please someone explain this.

I'm running CSF on a Cpanel server and have questions about new features in CSF
Apache Check
Check Apache weak SSL/TLS Ciphers (SSLCipherSuite)
Results
Cipher list []. Due to weaknesses in the SSLv2 cipher you should disable SSLv2 in WHM > Apache Configuration > Global Configuration > SSLCipherSuite > Add -SSLv2 to SSLCipherSuite and/or remove +SSLv2. Do not forget to Save AND then Rebuild Configuration and Restart Apache, otherwise the changes will not take effect in httpd.conf
Can someone explain this in laymen terms? I know this is new in Cpanel. I'm already running Apache 2.2, PHP 5.2.9 with suPHP enabled and mod_security as well (these rules: [url]
Also, what exactly are these CSF checks?
Check csf PT_SKIP_HTTP option
This option disables checking of processes running under apache and can limit false-positives but may then miss running exploits
Check csf SAFECHAINUPDATE option
This option closes a window of opportunity that opens when dynamic chain updates occur

I recently added ubl.unsubscore.com to my email server. I only have that one and the SpamHaus (Zen) activated.
I am able to see the SpamHaus listed on DNSStuff and on SpamHaus website that the person trying to email me is not listed.
So I have to think that it is ubl.unsubscore.com list. But what domain name can I enter into the browser to check this list? www.unsubscore.com does not work. A little searching led me to lashback, but the IP is not listed there either.

I finally nailed it down and came on a conclusion that my MaxClients were set too low so I had to set it to high number and it seems like that the proble of "Network Timeout" had been resolved but now the problem is still continued. Here is what I think is wrong
Cpu(s): 1.5%us, 0.4%sy, 0.0%ni, 96.7%id, 0.3%wa, 0.3%hi, 0.8%si, 0.0%st

Here's the exact error from DBI. It might help you debug:

I really need to track down the culprit!
i just don't remember what was the command to check logfile in linux to see what was going on in my server, since i think someone hacked in to my server and i was ddos last couple days.
