I have CentOS 5.5 x86_64 with Apache, php and mysql.
I have just installed OTRS (helpdesk - trouble ticket system) on that server and no users.
This system works with perl, apache and mysql.
I notice that is slow to respond and at times unresponsive the apache welcome page. code...
I have Centos 5.4 installed on my server. Everything works perfect, however sometimes apache does not work properly. When I write my domain to browser it tries to reach the site, however it can't get any result. (There is no "browser couldn't find" error). The browser just tries to get the content.
When I login to my server with ssh using my domain name, there is no problem. (Named works.) When I give the "service httpd restart" command the problem disappears.I looked at httpd log files but there wasn't any problem at that time.I use the API's of the Facebook and Twitter, so there are many Curl requests are made with PHP. Could that be the reason?
I am using Redhat linux 9.0 and using squid proxy server.My problem is tht i my squid server is responsing very slowing. whenevr i try to open sites the site starts to open after 3 or 4 seconds and often squid does not open the complete site. its stop the site in middle. My squid Configurtion is below. Is there any need to tune the system parameters Like from 'SYSCTL.conf' for better diskd performence or another problem. at this time i am using default system parameters. Please help me in detail what is the reason of squid slow performence if there ia a need of any system tuning please tell me in detail. I am very thankfull to you.I am really worried about slow performence of the squid. I also try to offline_mode on but the same problem. code...

I've just noticed that unrar is suddenly taking minutes to extract instead of seconds.
I can remember if its recently been updated, but I've uninstalled and reinstalled it and the version is: unrar.x86_64 0:3.7.8-3.fc10
I've found a few Ubuntu posts about it on Google, but in true Ubuntu fashion nobody has any answers!
What's odd is that when I unrar a file from (Nautilus or "unrar x *.rar") it takes say 4mins, then if I do it again it takes 15secs, like as if its caching somewhere.
So I just reinstalled OpenSUSE 11.2 and I went from having 20-30 mbps speed to and from my 1 tb usb ntfs external hard drive to having about 1 mbps transfer speeds now. Is there any suggestions for how I can fix this? I know it can go faster, I just need to figure out how. and would setting acpi=off at boot affect this?
Opensuse 11.2
KDE 4.3
64 bit
EXT4 main disk
NTFS external
fdisk -l code...
My problem is extremely slow write on hard disk and 100% cpu usage and it happens when I want to write something on the hard derive not any other external derive.
Tried a fresh ubuntu install. No change. I am not even sure if it is a software or hardware problem.
I have moved a site from a caps-insensitve server (OS X, Apache 1.3) to a default CentOS/Apache 2.2 install and run into problems.Actions:1) Made sure that mod_speling.so is loaded: LoadModule speling_module modules/mod_speling.so) Added CheckSpelling directive to Section 2: 'Main Server configuration'CheckSpelling on) Restart httpd
View 7 Replies View RelatedI am running a quad core centos 5.4 box that is having a strange problem with dovecot. The administration panel is able to send emails through dovecot but not any of the user accounts (ie with webmail). I've done a bit of research with what could be wrong but haven't had any luck so far I am also having a weird problem with apache: on a c++/php bittorrent application I was going to be running on a subdomain of my main site I get a 500 error every time I try to log in. The only way to get rid of the 500 error is to clear the chache (so its horribly broken somehow). The error generated in the log whenever I try to log in is that "ffmpeg is already loaded" (which I am running on the main site and is critical). Is there a way of either repairing my apache install or excluding ffmpeg on the subdomain in the conf or something?
View 2 Replies View Relatedon an old server of mine, as soon as apache is started, the load average that I get to see with 'top', that normally is under 1, now just steadily climbs up and up to easily 150, in fact disabling the webserver from serving any webpage. I've checked netstat, and I'll try to upload the output. The ip's that are in there I've blocked with iptables. But that doesn't help or so it seems. I see nothing weird in the error logs. As soon as I stop apache, the load goes back to normal. As soon as I (re)start it, up it goes again. What can cause this and how do I get rid of it?
p.s. It's an old server, fedora3 or so, and I've got a new one to which I'll transfer the domains, but until that's completely done, I'd like this one to run as it has for years...
I have a apache cluster with more than 10 nodes, based on ldirector and heartbeat. The problem is that I cannot predict if my nodes will handle the traffic in the next day (hosting a website based on daily campaigns). So I decided to limit the number of active connection on the nodes (from apache), but this is only a temporary solution. I want to create a page that will appear to users that are getting over the limit. Has anyone made this before? Can you tell me how is it possible (I don't want a how to, just a starting point to study)? I think squid can do it, but I don't know how to search for it. To give you an example of what I want, you can see the same thing on deviantart.

ProcessID "18753" is the one for "http://www.xxx.yyy.zzz/server-status" in my browser.
This command show me (In KBs) how much virtual memory is that specific process using:
# /etc/init.d/httpd start
# grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }'

Something make that process (and all the others httpd process too) to use a lot more memory!

I got a CentOS server setup as a dhcp server using dnsmasq. I followed this guide more or less: [URL] So, the problem seems to be concerning the DNS server on the clients. In windows I get the "limited connectivity" icon for the network, and when I select troubleshoot it says the DNS server does not respond. Issuing 'ipconfig /all' clearly shows the IP of the CentOS machine as the DNS server, which should be correct, yes?
ETH0 is working as WAN connection and that works great.. no problem with the WAN connection at all on the CentOS machine. ETH1 has the IP 192.168.0.1 and mask 255.255.255.0 When starting eth1, it sometimes says that it can't start eth1 because the IP 192.168.0.1 is already in use.. but that is most certainly not the case. Maybe there's some kind of issue here that messes with the DNS? What's mind boggling is that it works great on a linux machine (dhcp client) and on a windows xp machine. but it does not work on the windows 7 laptop and a vista laptop and a pda device.
I have a CentOS 5 Server running for private fun... Just for playing with it and learn a little linux.this server has to Network interface cards. one for connecting from extern and one from connecting from the LAN.when i want to connect from lan (eg via SSH) this allways works!when i want to connect not from LAN this only works sometimes! only if i establish at the same time a connection from LAN it wors mostly.with other devices i have no problem (tested another server with just 1 NIC) and this works too.also the problem is not dyndns because i have the same problem when i try to connect through the direct IP.

I cannot get either sendmail or postfix to send a 220 response, nor respond with details. See below for sample telnet output. Details: I have a server that requires email, but only for light use. I'm definitely not an expert, but I have set up a sendmail configuration on a previous server. I tried to configure sendmail first and then postfix later, when I couldn't get sendmail working. I'm not sure exactly what the problem is, but I have a feeling the following might yield some important information. Note: this is the result for Postfix, but virtually the same thing happened with sendmail, too. That is, initially the telnet connection would close immediately. Afterwords, I could connect a second time but then it never responded with a 220 banner nor any 250's.

i've been having some problems the last few months with my server/apache getting really slow (pages loading slow) and the only way i can fix it is to restart apache which is quite annoying and is not fixing the problem but it gets to the point where pages are almost not loading so i have to keep restarting apache but after 2mins it'll be slow again and once again i'll have to restart apache...i forgot to say that memory usage is a little higher then normal (500mb-700mb compared to 250mb-300mb - but goes back to normal after restarting apache) and the load is also a little high but always under 1 (also note my server is on a 100mbits port and i can easily push 100mbits 24/7 with no problems at all so it's not bandwidth)
View 14 Replies View RelatedI've been scouring the message boards and trying different things for two days and haven't found a solution. I set up Ubuntu 10.04.1 a few days ago using the server iso and selected the LAMP installation option. I will be using it as a sandbox to try out things from a PHP/MySQL book I purchased.
I have installed Gnome since sometimes I just can't get the command prompt to let me do things and Gnome may at least tell me why. I also installed PHPMyadmin.
My problem is that I can work with this thing all I want in any way I want - HTTP, SSH, SFTP, etc. - from within my home network but Apache refuses to respond to an outside request. Since it's only a test box it usually wouldn't be that big of a deal but I am going out of town for a couple of days and would really like to start working with my new book.
I am 99% sure my ISP is not blocking any ports. I have a ComTrend ADSL modem with router. I have given my Apache server a static IP on the NAT (xxx.xxx.x.101) and set up a dyndns address so I don't have to keep remembering the IP address.
Here is what I have tried so far: Setup a virtual server (port forwarding) on the router to to direct traffic on port 80 to internal IP .101The router told me its interface is using 80 so it would move itself to 8080 Made sure to also add port trigger for port 80 Made sure to save/reset the router Used my iPhone to connect via 3G - didn't work using IP or dyndns name Used iPhone to connect to 8080 and router responded
Set port forwarding/triggering for 8080 -> 80. No joy there, either Tried changing listening port to 8000Set port forwarding and triggering to allow port 8000 Changed ports.conf to read NameVirtualHost *:8000 and Listen 8000 Changed first line of /etc/apache2/sites-enabled/000-default to <VirtualHost *:8000> Restarted Apache service
Apache responded to dyndns.com:8000 from home machine No response when trying same on iPhone (sorry, it's the easiest way for me to test from outside my home network)
At one point, I added "ServerName localhost" to the otherwise empty httpd.conf file but that didn't seem to do a darn thing.
Many of the posts I have perused are at least a couple of years old and have included information on taking action with files that are not there or are no longer where they were. I have interpolated where I can but so far nothing has worked.
I can able to view there is high amount of memory & swap usage on the server, upon investigation found that there are high no of page faults happening on the server more than 300 .. Is there is any option to fix the page faults , and also how to release the locked memory with out using drop_caches..

When I first log in, I can press the brightness keys and it responds immediately for 4-5 keypresses. After that, it has a ~10 second delay between me pressing the key and the computer responding. When using acpi_listen, it displayed that it recognizes the event long after I press the key. This is a pretty minor issue, but very annoying. Here's some possibly-relevant output from dmesg:

A Linux (CentOS5.3) server is setup with apache reverse proxy. The reverse proxy server is opened to outside and an internal server is mapped to ProxyPass configuration. SSL certificate is also installed on the Apache reverse proxy server. The problem is, it is extremely slow in serving http requests through reverse proxy. There is no problem with server resources or bandwidth. When the internal server is directly accessed through Internet, there is no delay. The backend server and the reverse proxy server are also on the same switch (same subnet). When I searched the Net, there were recommendations to enable cache in Apache. I did so as follows in httpd.conf.
<IfModule mod_disk_cache.c>
CacheEnable disk /
CacheRoot "/var/cache/mod_proxy"
CacheDirLevels 5
CacheDirLength 3
</IfModule>
But still there is no progress. Do I want to enable cache in ssl.conf too? Or is there any other workaround to speed up Apache reverse proxy. Is there a way to check that caching is happening?
I'm having trouble with my database server run with PHP & MYSQL; i just installed this system on a SUSE Linux Enterprise Sever; the Server its self is an HP Proliant ML370G with 4GB RAM
The system was fine for like 3 weeks until recently when it started slowing down. Apparently, eveything is normal when you are accessing the server, for example when you are browsing on the database web interface; but problem is when you start working in the database, when you try submitting into the database, its really slow on processing, i have to first restart the mysql;
Could it be RAM? or the SQL itself?
I am installing Big Brother on a CentOS 5.2 running the default Apache 2.2.3. When I try to access any web page I get the following error: Forbidden You don't have permission to access /bb/ on this server. Apache/2.2.3 (CentOS) Server at fmsubbnix Port 80 So far I have:
1) Set the Directory options to FollowSymLinks
2) Verified all directory and file permissions are at 755
3) Set permissions temporarily to 777 and received same error so I am assuming the issue is in a config file somewhere
4) in hhtpd.conf verified <Files ~ "^.ht"> is correct
5) verified the "default" directory is correct (/var/www/html)

I have changed my home network a bit, and everything works extremely fast, except for my apache server, which seems to serve webpages so slowly, it is abnormal. Even simple directroy pages are served in around 5 sec, and this is not a joke! It used to work pretty fast. What I have changed is that i replaced a hub with a switch, and that I linked my personal PC with my server together through a hub. I also installed Gnome desktop on the webserver machine. My network now looks like follows:

Any idea how can make the authentication fast?
