During this i don't change any setting, so less chance misconfiguration
this is getting out of control. I have a dedicated server that is "unmanaged" meaning, I manage it
I typically can make my way around a server and do most things - but in this case I'm stuck. I host a number of websites on this box and have went over a year with little problems. The past month or so it seems as though the server crashes daily or every other day. It will be running just fine, then all of a sudden the processes and loads will go out of control until the server is just unusable.
What do I need to provide here for you to be of any help to me? I watch the processes using "top -ci" and it's typically small output - but when it's getting ready to crash it's like a ton of processes get backed up and continue running.
Code: Kernel Version2.6.18-4-686 (SMP) Distro Name Debian 4.0 Model Intel(R) Pentium(R) 4 CPU 2.40GHz I've installed the default apache 2, mysql, php using aptitude.
The server load is not at all high, around 1-1.5 max. The apache processes running are at an avg 60-80. It has 1GB ram and Disk Swap usage is 0kB
My server keeps rebooting every now and then. These are the messages I get in the ssh session just before the reboot..

I have a VPS with following features: Dual Xeon, 512MB Ram (up to 1GB), CentOS. Unfortunately MySQL is frequently down, about once per day, and it takes time to set up again. to change mysql config to resolve this issue?
I have a VPS with 2GB RAM. The load is always around 0.5 - 0.7. It's Xen VPS, and I see the VPS doesn't use swap yet. However, Apache is going down frequently. Might be 3-4 times per day, and DA informs me about the downtime when trying to restart Apache. In apache error_log, I haven't seen any special error. Just few lines like this Quote:

I wonder why Apache is going down frequently, and how to fix it?
I have a cpanel server with 2GB of ram. For the last two weeks , we are experiencing problems with apache in the server. Apache goes down frequently in the server and we had to manually restart the service everytime. chkservd do nothing for a restart. I had recompiled apache using easyapache script.
Strangely i can see some entries like the following in apache error logs
host: isc_socket_create: not enough free resources
I compiled it one more time but the errors still exist.
I've been running 3 Xen servers for the last few months in a production environment, and facing a strange problem with one of them.
Server 1 and 2 run a couple of DomU's and are running just fine.
Server 3 runs one DomU and takes care of all the backups for the DomU's of Server 1 and 2 The DomU on Server 3 is crashing every night, right when the backups are being made. DomU becomes inaccessible, but keeps appearing at xm list with state ------
When I try to connect to the console it wont let me connect. The only way to get the DomU back up is by using xm destroy and xm create again.
For the back-up I use NFS where the DomU on Server 3 is the host, and the other DomU's of Server 1 and 2 connect to it through an internal bridge.
Below you'll find some information about Server 3:
Hardware: HP ProLiant DL380 G5 10Gb Memory ( 8 x 146G SAS10k in RAID 5 )
Many a times websites hosted on my Red Hat Linux server would not open even though Apache and everthing else is up and running. When i hit reload on browser 4-5 times the website would load or i have to restart Apache and everything starts working normally.
Today when this problem resurfaced i did not restart Apache and looked for in apache logs and saw this strange entry in apache Error Log;
[client my.ip.xx.xx] script '/my/website/httproot/mdqt.php' not found or unable to stat
The above was in apache Error Log, above is my ip address, and i never requested a file named mdqt.php, in fact no file by the name mdqt.php even exist on my entire server.
I then looked for mdqt.php in error logs and saw several requests made for this file and from various IP addresses.
Attached is a (badly) drawn diagram of two sites, connected by a vpn.
The site to the left, is network 10.0.0.0/24 which runs a linux server as the router for the network.
The site to the right, is network 10.1.0.0/24 which runs a windows 2003 server as the router for the network.
Now, my problem is, the clients behind the windows 2003 server can ping any machine on the first network because i setup a static route to route all traffic to 10.0.0.0/24 over the vpn interface.
now, my problem is, only the linux server can ping any machine on the windows 2003 network, any client behind the linux server cant seem to route over the interface.
I have the following route on the linux server: .....
Starting point: a working site using a shared IPv4, dedicated IPv6, and SSL. HTTP and HTTPS work, the latter only using SNI of course.
The good news: If I simply allocate an IP resource of 1 to a subscription it is pulled from the pool, assigned to the service node, assigned to the web site, DNS is updated, and the site is automatically changed to using a Dedicated IPv4 and Dedicated IPv6.
The bad news: visitors land on the default web site of the service node, with the default SSL certificate.
Other info: I can't ping the new IP, even though it shows in "ip a l" and /etc/sysconfig/network-scripts/ifcfg-eth0:0. [edited]
After the IP assignment, it is still installed, and /etc/httpd/conf/plesk.conf.d/ip_default/domainname.conf shows the new certificate is being used.
However, a second set of VirtualHost entries is created in server.conf for this IP for ports 80 and 443, with NameVirtualHost enabled on the new IP. The port 443 entry uses the default certificate. Apache's setup this default VirtualHost entry will override the web site configuration because Apache is listening on port 443 with the wrong cert.
If I go to "Change webspace settings" and toggle to Shared IPv4, Dedicated IPv6 the site works again via HTTPS, and Dedicated IPv4 and Dedicated IPv6 breaks it again. Setting the SSL cert to None and back again does not work.
Setting the SSL cert to None, changing to a dedicated IP, and enabling SSL results in the server being inexplicably inaccessible...browsers no longer connect to either the default site or the correct site, and I don't see any entries in the vhosts's logs.
I have read another recently created thread about their woes but this is a separate issue so I figured it deserved a separate thread.
Here is my problem.
I am transferring my site, osrec.com from my old server to Hostgator.
The old server is quite primitive and I am using this piece of crap:
Matrix Hosting Appliance Control Panel v2.0-33
I have hardly any control or options.
I am using Joomla 1.5....but my concern is that the MYSQL database will not be compatible.
I am also concerned about downtime...What if they transfer and it isn't compatible, am I then stuck with a site that won't function properly. Is there a way of transferring it to another domain hosted with Hostgator first?
Has anyone transferred a Joomla site over to Hostgator? have you any advice?
I know, a lot of questions and not really structured. Fact is, I have never experienced this before and so this is my first time facing it.
I'd contact Hostgator, but....ya know...their technical support is useless.
I own a site that is MySQL driven, shared hosting is no way to go now with over 100 guests on the site, and alot of MySQL usage...
My question is, do we need a dedicated server? or the site would function great with 99% uptime on a VPS?
Another issue is, the site gets DDoS / DoS attacks between now and then, haters out there... so would a VPS be able to stay up against the attacks? can I install CSF with no problems? or any other firewall?
Let me know what you think, and if VPS is the way to go, please suggest some VPS hosting providers...
Currently i want to transfer my site to new server : 1. I go to site cpanel -> backup click on "Download a home directory Backup " and "Download a MySQL Database Backup"
I download all file and mysql data to local pc first.
2. I go to new server cpanel -> backup browse the zip file and upload it, for mysql database same, browse zip file and upload it..
Then problem come, after i have done, i go to cpanel->MySQL database, i can found my database is there, but all the mysql user is lost, I try it again and again.. but the result is same.
I would like to build a personal website powered by a content management system and I'm wondering: How many SQL Server databases a site requires? At the Godaddy.com site, the plans for Windows offer one, two or three SQL databases and at least 10 MySQL databases.
my vbulletin site has been growing significantly and the server has crashed many times due to the high loads. My server guys tell me that mysql is hitting loads of 30 (not sure what that means) and i need to get another server for mysql alone.
They recommend that I shld go for raid-5 for the mysql server due to performance and redundancy. Thus if i was to upgrade now, I shld just go straight for a raid-5. Is that true?
I am currently working on a File hosting site like sendspace, megaupload (Not that big, only a small site for college students use it). I am wondering which hosting company out there take high disk space and unlimited brandwidth.
I rented a server from VD a month ago and hosted some of my websites. But I'm constantly noticing that my websites are loading very slow. How can I check if other users are experiencing the same problem, or if the problem lies with my Internet connection?
After having my site on an Win2k3 virtual server for the last 10 years I've finally bitten the bullet and purchased a VPS account.
My site is an old legacy of MS Frontpage, complete with FPSE, Access databases, asp, html pages and lots of images. Total size is just over 4Gb.
I've tried publishing the site using MS ExpressionWeb direct from the virtual server to the VPS, plus I've tried to Publish them from the backup on my PC. Nothing works. I just get error after error after error.
EW starts to publish and maybe will run for 4 hours before throwing up an error saying that it can't find the web server or FPSE aren't installed. They are basically the same old error messages that all of Microsoft's Frontpage and Expression Web software have been throwing up since the day Frontpage was first marketed back in 1998! If they can't solve the problem you'd at least think they could change the error messages.
I've tried uploading them via FTP but without the MS server extensions the child webs aren't created so therefore I just end up with permission problems and nothing works properly-
I plan on purchasing a dedicated server to run a few proxy sites. However, i don't have a lot of Linux skills to administrate my own server. But i've always been able to figure stuff out so i feel pretty confident that i can get it going on my own. Anyways, My original idea was to use cPanel to run the web server for the proxy sites however i feel that using cpanel is not a great idea since i also wanted to maximize my servers performance and i hear cPanel can take heavy resources. So anyways, I just wanted to know what some other people here might think and if possible any recommended guides on setting up a linux webserver would also be appreciated as well.
We have a client that is normally low use. about 200+ hits per day. They are a non-profit, and get TV coverage (like the Today show, Dateline, NBC nightly news, and coming up here soon final 4 news spot) about once a month. When this happens, they get 60k hits a day.
they crash my dedicated server a few times. I have a dual p4 w/ 2 gb of ram. I only have 60 clients on this server, but as they get more coverage, our server cant take this many hits.
whats up fellers, i'm attempting to point my design site name from whm, to my home i.p address by changing the i.p in whm dns zone editor. I'm doing this because its just so much easier to copy an ad, or web site or whatever i do to the server via my home network so the client can see the project pretty much in realtime (some ads are like 800mb) . ALSO i'm trying to set up exchange so my motorola q will have realtime email.
Anyway, so "mysite.com -A record -i.p.addy" Now the site comes up.. and i get emails.. but i cant 'send' any emails and windows server is telling me i have a non existing domain name.
so the question is am going way over my head and should i just use a service like no-ip or dyndns or can this be done?
