I run a heavy site, and httpd always failing...
I have a server with these specs:
Q6600
8GB RAM
500 GB SATA HD
Cpanel/WHM
I run a filehosting site actually and there are alot of people downloading at the same time which i think the server goes down and then httpd restarts itself and all the people downloading the files, their files get currupted.
How can i make it so it stays stable?
for the past 4 days i have being having problems with my Apache server. on day one i noticed it was going down irregularly over day 2/3 it got progressively worse by last night httpd would only work after i restarted it then 5minutes later it failed again. now it wont start at all every time i tried restarting from whm it just says 'httpd failed' ive also tried restarting from shell but no joy. ive tried rebuilding apache from whm that hasn't helped either. one error i was getting was 'invalid user name' of a user who i terminated yesturday.
View 7 Replies View RelatedBefore I used to get around 5-6 a day emails saying that httpd has failed and a restart has been attempted automatically.
After I increased the max clients in the httpd.conf the number reduced 1-2 emails a day.
I am not sure what the problem exactly is
Is it because my sites are using up high bandwidth?
I noticed all of my sites were down earlier.. so I tried restarting apache via WHM.. and that didn't work, said the following:
Waiting for httpd to restart.... . . . . . . . . . . finished.
httpd status
root 8103 0.5 0.8 30892 29264 ? S 12:28 0:00 /usr/local/cpanel/whostmgr/bin/whostmgr ./reshttpd
httpd has failed, please contact the sysadmin.
I tried rebooting.. same issue.
how to troubleshoot this? This is very bad!
I built the system on Centos 6.5 with plesk 12 with a range of ips. I then (after the fact) copied the IPs of the old server to the new and moved all the domains to their IP's. This way today we flipped the routes and all should work.
The problem is that the domains only work when putting :7080 behind them. It seems like the httpd is only listening on the old IP and not the new ones. How to make plesk/httpd listen with the new IP's on port 80"
httpd.conf
#Listen 12.34.56.78:80
Listen 7080
I added all the other IP's and tried changing ports under Listen but that does not work either. So changing the listening port does not work.
I can access FTP, SSH and httpd is showed as running when i check with 'httpd status'. Memory ram has half of them left(except that swap is 0,0).
I can't access my site via browser
Why tried restarting
[root@web2 ~]# service httpd start
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

[root@web2 ~]#
When i do httpd -S i notice one of my sites show with 2 config source. but i just config one file for the site.
for example:
[root@apachesrv ~]# httpd -S | grep devel.site.com
default server devel.site.com (/etc/httpd/sites/000-default.site.com:1)
port 80 namevhost devel.site.com (/etc/httpd/sites/000-default.site.com:1)
port 80 namevhost devel.site.com (/etc/httpd/sites/devel.site.com:1)
the problem is the following, when i do reload and in this moment the config is bind this result, the site is blank.
Why it shows me this.
version of apache
Server version: Apache/2.2.15 (Unix)
I have some websites running on my LINUX server now.
Not all of them are running stable commercial scripts or cgi.
In fact, our server had some records down before by some package scripts.
I only know TOP to know the current server status.
But I can not know which PID is making CPU usage high, or which website.
I think if I can check the exact site or cgi causing heavy loading. Perhaps it helps us to make our server up.
Is there a way or LINUX command to find out which PID is causing heavy loading?
For past one week, my wordpress based blog is just dead, becasue of heavy trackback/pingback spamming(500 a minute). I've tried various plugins, but to no avail.
In addition to stop spammers before generating PHP load, I've tried all possible HTACCESS rules, but to no avail. I truly sure, I've done something wrong.
May I request the experts here to advice on how to stop this ongoing spamming?
My website (Large Discussion Forums Site) is under a heavy DDoS attack since 3 weeks. My first host could not handle such an attack so I moved to another who claimed to have a firewall that can handle the attack, but still, the site is down.
Anyone has a good suggestion to get the site up and handle the attack? Any particular hosts that can help me?
(The Forum has its own server and does not use Apache).
on my top process am having this one as shown in the attachement image
its consuming time+ of 746:21:95
on the Process Manager that mysqld process is using the command
/usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/host.theplanet.host.pid --skip-external-locking
is that process normal? and what is cousing it? should i kill it?
I have a Windows Server 2003 Enterprise (32 bits) running IIS 6.0, with ASP.Net 1.1.4322. Basically it's an application and image server, that has a large amount of concurrent accesses.
Around 800 users simultaneous access simulteneously and ASP.NET app, that will request some date from an MS-SQL Server database and point the browser to image file (all at once), every few seconds (it's a live webcast applications). The server is quite robust, with 500 GB in a RAID-5, 4 GB RAM, Dual Opteron Processor.
When the users access it, the machine memory and CPU usage a low. Also it has plenty of bandwidth, since it's directly tied to a Gigabit port on the datacenter. I kept an eye on all paramenters and there is no imporant bottleneck on the hardware side.
Here is my problem: after some "images" are sent, with 800 users, the users start getting a 503 error, and can no longer access the images.
On IIS HTTPErr Logs, I found these errors to be "Timer_ConnectionIdle". I believe it has something to do with the way the Application Pool is handling all those concurrent connections. No references to it are made on Windows Logs.
I've already tried tweaking all those paramenters on the Application Pool, but no results. For example, I tried increasing the Request Queue Limit value, but that doesn't seem to make any difference.
Also, I inserted "MaxUserPort=65534" on TCP configurations on regedit. Rebooted. Also, tried turning off keep-alive and decreasing connection timeout, then a restart of the w3svc (see [url]for the explanation about this). Tried changing each parameter individually and tested. No big difference after each modification.
Has anyone ever seen this? Is there a way to get this solved? Again, this address [url] has a description of what seems to be my problem... but I didn't manage to get this solved.
I'm currently considering to enter the VPS market
I have recently acquired a nice box (2x Dual Core Opteron 275 2.2 GHz, 16 GB RAM, 16x500 GB SATA @ RAID5/6) but I'm unsure if it isn't smarter to buy smaller machines (like X2 5600+, 4 GB RAM, 2x400 GB HDD) and put like 15-20 customers on it.
Yes, I know that the hard drives are more than oversized for VPS hosting
The Opteron server will have a very, very nice I/O performance so that customers are going to have a good feeling while working on it. To refinance the costs it would of course be neccessary to put not less than 125 VPS on one box, so I can imagine that there'll be a bottle neck somewhere (CPU power I'd guess?).
What is your opinion? Big boxes with high performance and loads of customers, or small boxes with not-so-many VPS?
I am running a VB forum using lighttpd and ranomly one of PHP proccess is using about 80 90 % of memory ! and i should kill it manualy

One of my Cpanel servers is showing heavy data transfer this month. In 6 days, it crossed 600 GB data transfer which is equal to what it did last month. Also, all the websites collectively have only consumed around 60 GB data transfer in 6 days. How do I find out what exactly is causing heavy data transfer?
View 14 Replies View RelatedAre there any hosting companies that use an Enterprise strength SPAM solution such as IronPort?
We have 3-4 business websites and spam, especially within the last 6 months, has become a tremendous problem. At least 100 spam emails a day are being delivered.
Spam filters do not solve the problem - they simply put some percentage of spam in a folder, often genuine emails, and we still have to go through it manually.
Do not mind paying a premium for the hosting. Any hosts that offer HEAVY DUTY spam protection?
I have 2 identical Fedora8 boxes with Apache 2.2.8, MySQL 5.0.45 and PhP 5.2.4. I use one as the Web+DB server (say box A), and the other (box B) just as the Web server connecting to the DB server on box A. I use this 2 machine configuration to test a LAMP based-Web application. I have a client program on other machines that can emulate a massive web workload to these 2 servers; it can emulate hundreds to thousands of users using the application simultaneously.
Before running the test, the connection to the DB server from both boxes seem fine. Using the mysql client program on either box A or B trying to connect to the DB, the connection goes through instantly. In the /etc/my.cnf file, I have max_connections=4096 and max_user_connections=4096. Note that the web app uses one single db user to connect to the db. To allow remote connection, I inserted one record into the user table of the mysql db whose the host field's value is '%' (allow connection from all remote hosts).
After running the test (which I found out that many requests sent to box B failed), mysql client program on box A is still able to connect to the db instantly; but the one on box B has a problem: it takes extremely long (5 - 10 minutes or even more) to establish the connection, it doesn't time out, just takes that long. I believe that's the cause for the failure of requests to box B.
We are facing a very problematic situation since last several months due to accessive bandwith usage. But we are sure this is only local traffic.
We have 2 Servers with our hosting provider
Server A - this is a VPS
all our webfiles/domains/dns/nameservers reside on this server
Server B - this is a dedicated server
contains only databases
(we are actively running vbulletin based forums on this servers)
Since last several months we are facing huge bandwith increase since we have transferred only our databases to Server B. (earlier database + everything was on Server A) We never ever consumed even 50% of the entire allocated bandwith in past when we were on Server A.
But only after moving the database from Server A to Server B we have found this tremendous increase,
Can we do something about same ? as both the servers belong to same hosting provider.
We are not sure but expect that this is only local network traffic between 2 servers.

View 3 Replies View RelatedJust got this server setup, getting some smart errors. Here's a copy of the trouble ticket I posted to the host, they said "If you read through the documentation for smartd you will find that from the results you pasted, your hard disk passed every test. We can give you another hard disk if you want but we will have to charge you 3 credits for the reinstall of the operating system." I could be wrong, maybe everything's fine, but the fact that there are unreadable sectors reported has me a little worried.

N/A
Have you done anything after this error occurred?
Does anyone know any reasons why this process would be failing?
I installed ASSP X onto my cPanel VPS, assp2 seems to be failing every so often.
For some reason BIND keeps failing on my cPanel server every couple of days. There are no error logs in the /var/logs/messages file concerning the crash but when I manually restart bind then it logs messages just fine and I can see them. Does BIND keep any other error logs?
Today it seemed to coincide with a big movement in system memory, here my munin graph:

I have ran the “fixeverything” script which attempts to correct any errors in the bind config file but it still crashes. I couldn’t see anything wrong with it ayway.
/dev/sda1 is mounted to / on my dedicated server, however, it is 100% full and cPanel is having problems with it. Is there a way I can clean out some files?
Additionally, I cannot SSH into the server since sshd keeps failing. Anyone know what I can do?
I'm sure /dev/sda1 isn't usually mounted to / but who knows.

I'm having a problem with my CentOS 5 box. for some reason the update will not work.
I run yum update, The update starts, then when it gets too downloading the packages I get the following error for every single RPM.

The RPM's can be downloaded just fine if I copy and past that URL in my browser. I don't understand why the server can't open that URL
Does anyone know of a fix for this? Or is anyone else at iWeb having the same problem.
The second week of July AmeriHosting moved my VPS to a new server or something and changed my IP addresses. No big deal, except the move failed miserably. My sites were down for a week. Shortly thereafter, email was down also for a week. What had worked on the old VPS did not work reliably on the new VPS. Messages sent to support went unanswered, or were given inadequate responses. They also could not go back to the old VPS which was working acceptably (and had for 2 years); I do not know why. No backup was made or else they could have gone back. That's what I think anyway. On the new VPS they did not have the same version of PHP or PHP modules. This broke some of the sites; and asking them to correct the problems as they were discovered took several days up to a week. Now the first week of September, and problems persist. This time I cannot issue a backup in Virtuozzo. This has been going on for 2 weeks. I get a response every couple of days about this is being looked into and they will respond, but no one ever does.
I've been told on several occasions the past week that they were going to move me to a new VPS but keep my IP addresses; this has not yet happened and it has been a week.
Twice I was told it would take only a few minutes to do this and it would be done that day. It has not yet been done. To add to the matter, I prepaid for a year, and I have 6 months hosting left with them. So I feel pretty damn screwed. My largest hosting customer has just moved sites from my service to another service this past week, so I am clearly losing revenue from this ordeal. Phone calls have gone unanswered (during the freakin' day!). Messages to billing and support get absolutely no response. Tonight I left a message that I wanted the name of the president or owner and his phone number so that I might enlighten him about the problems his customers are having and the dire straits his business is in.
At one time I would have recommended AmeriHosting.
Not now. Not ever. Don't even consider AmeriHosting. They'll **** you good at some point and harm YOUR business and YOUR CUSTOMERS' businesses, too.
