we manage about 400 linux servers, every time that a new kernel is out or that we need install something we must login to each box and lanch the command, i think that this is a old system that can be used about 10 years ago how do u manage large servers upgrade? is there any tool that we can use to lunch command on several box?
View 3 RepliesI have a few dedicated servers, and I noticed recently that one of them is 4 years old.
The server ran "fine", but what ~$200 could buy 4 years ago is a lot different than the technology, speed that ~$200 can buy today.
Is that a good sign that it's time to get a new dedicated server?
Do you ask your current datacenter to upgrade the current server or do you just get a new box and migrate your data to the new beefed up server?
The issue we have is that server1 (web) has the load very high, compared to server2 (mysql). Sever2 stays at 0.5 during peak time.
I must mention that we have very heavy traffic hits only for 30min/day, then things calm down.
I simple diagram would be:
[USERS] <= NIC1 => [SERVER1 WEB] <= NIC2 => [SERVER2 MYSQL]
So I think we can install a load balancer and upgrade the NIC cards, in order to solve this problem.
What I thought is this:
In server1 (web) install 2 NICs, one facing the users and one facing the server2 (mysql).
Currently we have a 100MB NIC card into each server.
The 95th is way to high at peak time, over 500MB so I was thinking on installing a 1GB NIC facing the server2 (mysql).
My question is:
What is the best way to install a second NIC into an existing configuration?
Do I need a Cisco 2970 switch?
Example:
[USERS] <= NIC1 | NIC3 => [SERVER1 WEB] <= NIC2 => [SERVER2 MYSQL]
I'm running a message board and it looks like I've outgrown the low end xeon 3040 1.86GHz dual core server, and the bulk of the CPU load is going to mysqld. I'm debating between offloading the DB to a dedicated server vs upgrading the existing server and hosting the web server and db on the same machine.
Any thoughts on the better approach? fwiw, the load from apache seems next to nothing right now, but I am also planning on adding an SMTP server for user registrations and general support email.
I'm also not super familiar with dual-core and dual processor machines. Does shifting mysql to a dual core or dual proc machine help (vs a single core/single proc machine)? since there is just one mysql daemon, does having a second core or proc. buy me anything?
I have a server running cPanel.
At the moment, I am been hosted on an unmanaged server (dedicated).
My server provider is offering $25/hour for managed support.
My Kernal and Centos have not been updated for a while and I am looking to upgrade both of them. I am wondering how long would these 2 jobs normally take?
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.
there is the error in our server

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.
View 6 Replies View RelatedI'm in a vps with 512 MB ram now, my visitors per day is 10K and from top command, i just use about 200 MB. But, my vps is always got downtime everyday about 30 minutes. The CS said it is because my ram, the top command is not representing the real ram and recommend me to upgrade my ram to 768 MB.
Should i upgrade my ram?
I run the website for a small but profitable business. We currently have a shared hosting package with Midphase (who suck horribly) for about $10/month, and I'd like to switch hosts ASAP.
I need to stay under $50/month, but my question is how much do I need to spend and would I benefit from VPS?
Our requirements are relatively modest (see below) but we need rock-solid uptime, fast transfer speeds, and quick/effective support should we need it. I'd also like to keep using cpanel or something equally easy.
Here's are current stats:
traffic: 1000 visits/month or less
disk space: 5GB
bandwidth: 1.5 GB/month
mysql databases: 3
scripting: We also have a couple of wordpress blogs installed and run a small php script daily via cron
I try to relocate a database from my MS-sql8 server to a MS-sql 10. I can't get it to work as it should on the new host.
I have used the deattach / atttach method and after that i can login to the db in the new server and make selects. However stored procedures or views does not work. If i try to access them from a vbscript it get an error telling me that the stored procedure does not exicst. If I use the admin tool I can verify that it is there.. Can someone explain what to do? the db is owned by the user and should have all user rights thats needed, but apparently i guess that something is missing.
I have had a VPS at Futurehosting for over 2 years, that I am very happy with. Currently, the OS is Centos 4.
At what point in time should I upgrade to Centos 5? And are there in pitfalls when upgrading from a system that seems to be ticking along happily. Are there many incompatibility issues?
Also, similar question for Apache 2 and MySQL 5?
I have a test VPS set-up, and I wish to upgrade to PHP 6 to test out my pre-existing websites (and make any necessary changes pro-actively).
Can anyone point me in the direction of how to upgrade it (and then configure Apache 2.2, MySQL 5 etc as needed)?
I have a linux VPS server.My trouble started when I bought a script that required me to install PHP5. Currently my server have 4.3.9.
Being a linux noob, it took me 2 days to install PHP 5 but now the problem is everything is still using PHP 4.3.9. When i do a phpinfo(); it shows php4.3.9.So, can someone please tell me how to tell the system to use PHP 5.
I used the exact same ./configure command as i see in the PHPINFO(); for PHP4.3.9 i.e

Currently my ensim server's PHP version is 4.3.9, and i will want to upgrade it to version 4.4.7. But i have never upgrade PHP before.
Is there any guide which can guide me on how to perform the upgrade? I heard that upgrading through RPM is a faster way?
I have a dedicated server and currently its running php 4.4.7. I need to upgrade to atleast 5.0 to run a script i purchased for my new website. Script wont install unless its php 5.0.
So here is what i did:
logged into my whm under root...clicked on Software-Apache Update
Now i have a list of software i can install. So i selected php module version 5.0.4 and clicked on start build. It ran and then my server restarted. But now when i try to open any of my sites on that dedicated server it does not open them. It makes me download each page i try to open.
Example i go to www.mysite.com/index.php it will ask me to download the index.php file.
How do i install php 5 on my server using cpanel/whm
I currently have a LiquidWeb VPS1 since April 15, 2006. Over-all very happy with it (minus the cPanel crap cPanel pulls). They are running a special on all VPS's and dedicated and am thinking of moving to the VPSII plan. CPU load is low and RAM/System usage (is that RAM?) usage is sitting at 55% (after 5 days).
I do "Family and Friends" hosting and it covers it now, but I couldn't afford to pay for the VPSII on my own, but with auto monthly payments from Friends and Family I could afford it.
Reasons for looking at the VPSII plan? 768MB RAM and double the CPU. My friend is hosting with me and runs all Drupal sites (same with me (once they go live). Drupal seems to like a min of 32-64MB for the php.ini file. Disk space is 56% not that big a deal.
If I pay the $150 setup fee, I can reduce the monthly cost to $25/month more then I pay now. So my question is, is it worth it? Is it worth it if I get the funding on monthly going?
I have a server that requested to do hardware upgrade the noc couldn't make it right with the same hdd so they just make new machine and connected the old hdd as the 2nd hdd
(/oldhdd) to this new server where in the old hdd are all data and have to import all accounts to this new server or the better way would be to make it primary and that would save a lot of time not having to create add each account one by one then copy files and start making all the configuration of the server from scratch but my concern is all for accounts.
It has cpanel and there are more than 200 accounts.
Upgraded http apache from 1.2 to 2.2 quite new in 2.2 and also upgraded to php5 but after that facing two thing before upgrade in my process running only have mysql and httpd processes but after this upgrade php5 process also join them now three process running .
And secondly many time when people try to browse my forum base site then they are getting done page which is blank page nothing happen just done and nothing display on page but after keep refreshing got forum page . but need to refresh 2 to 3 time i am also new in http 2.2 envirment how to optimize it as well thanks in advance God bless you .
I never done PHP installation from source code. I have Fedora server with PHP/MySQL/Apache installed and tuned for needs of my site.
I wonder how can I upgrade to 5.2.3 and keep all settings and modules as is now?
I've googled for it but found nothing (I've found some instructions, but for other situations).
When I attempt the upgrade to PHP 5.2.1 using apache update in WHM. It doesn't upgrade. It looks to doa basic version check and then restarts Apache. Is this a known bug or is there a way that this can be corrected?

I'm currently on RZ Advance Plan for almost 2 years and found them to be ok. Well I guess I don't bother them much as I'm hosting mostly very low traffic corporate sites which utilizes email rather than anything else. However we had a couple of email issues on and off and it normally will be ok after we submit a support tkt although RZ will always maintain that nothing is wrong. The spams issues though is still unresolve to date. I'm not sure if getting a new provider will change all that either.
Then there was a week when I'm developing a site for a client and was working on it at around 3 - 5 am Singapore time.
There was at least an 5 - 8 occurances of intermmittent downtime lasting no more than 2 -5 mins on the site during that hr, when questioned RZ said thatit was a peak period. 2 - 3 mins of waiting time for that amount of occurances doesn't seem too
good when you're developing the site right? So I'm considering ..
Should I upgrade to RZ Failover plan or Liquidweb VPS. Liquidweb server secure feature attracted me the most as it mentioned
the spam issues that is crucial for me.
I like RZ end user support but not too confident with the email/ spam issues will be any better. Do you think getting Liquid VPS with 384dedicated RAM suffice for 30 - 50 corporate sites? I'm setting a budget of no more than $100 to include external end user support. Possible?
What would give me the best performance, to have many low end servers (core2duo) or a few high end servers (quad cores, dual quad cores).
Running everything from mysql queries to video streaming.
I am looking to upgrade my hosting account from IIS 6 to IIS 7, as I haven't been able to install some of the apps that I want on godaddy. I am just looking for a quick direction should I upgrade or not? I am not very knowledgeable about IIS thing, Godaddy says that If I upgrade I will not be able to downGrade, that makes me more snif*
please has anyone upgraded? so please tell me what would the consequences? or if any godaddy staff reads it please also tell me that on Upgrade page it shows me my directories, should I check them all?
This is more aimed at providers but do you allow partial upgrades on RAM/Disk/Bandwidth?
I'm asking as we have one brand which is fully automated which I refuse to do partial upgrades on as its done as a budget and if a user needs more they need to upgrade to the next package but it is budget.
On our more expensive brands we do allow partial upgrades
