How To Add Cron To Restart Apache Server Every Three Hours
May 5, 2008
My host is experiencing "issues" with my WordPress. It keeps going above their upper limit of open MySQL connections. So, while I am diagnosing it, I need to restart the server every few hours to avoid it going down.
How do I write a cron to restart Apache every 3 hours?
ive got a fairly beefy server but at the moment its hosting alot of resource intensive sites (unfortunatly i dont currently have a choice on where to run them all) and apache is crashing to the point its taking upto 2 mins to load pages within about 24hours but once restarted is fine again. so im wondering if anyone can suggest a way to automaticly restart apache via a cron job every 24hours or so?
I want to setup a crontab to delete a file every 24 hours, I am not the best in crontab so was wondering if one of you could please give me the command I should use?
I would like to replace my index file every three hours, with a specified file on the server thats in a different folder (someone keeps putting unwanted stuff in my index file) Can someone explain to me how this is done?
I'm having a bit of trouble with one cron job that doesn't seem to work.
I have others scripts that run hourly fine. However this one does not.
The script:
restart_monitoring.sh
Code: #!/bin/bash service iptables stop service iptables start /root/bandwidth_rules.sh /root/portforward_config.sh exit The two scripts at the end just load a lot of iptables rules back in.
The cron job should run hourly (59th minute)
The cron job entry
Code: 59 * * * * /root/restart_monitoring.sh I have restart crond to enable the new job, still doesn't run.
The job is to restart iptables, thus flushing all rules that I have running, then reloading them. I have figured out the problem to be with the "service iptables stop/start" command, it doesn't seem to like doing this...?
This one's pretty simple really, but given the fact that I'm constantly running into crond stops with CPanel servers (no clue why, or where, but it's happening), I'll post this here. If it helps someone, then great, if not, hey, no worries.
Firstly, login as root to your server through ssh, however you usually do .
Next, the script (we'll call it /bin/croncheck.sh). Use whatever editor you choose to create the file.
I have 8 apache servers that is sharing one httpd.conf file... When changes made in the httpd.conf, you have you restart httpd... How can I restart all 8 servers at the same time instead of logging into each server and do it manually?
We are unable to restart apache on our server, as a result no sites are accessible in the browser. Our host states we need to clear out the following files:
I have no trouble logging in through SSH Also no problem accessing webmin on port 10000
I've tried to restart Apache httpd And tried to reboot the server...
Nothing.
I recently did a Yum Update, also removed ISPconfig - it's probably the latter thats the problem, although I haven't used it - at all - just playing around setting up PHPmyadmin, Squirrelmail and a couple of email accounts.
But the only error log output I get is that there are no virtual servers for 88.198.81.186:80 and 88.198.81.187:80 and Unable to open logs | unable to start piped log program
Since the update and removal of ISPconfig 4-5 days ago there hasn't been any issues. I haven't done anything. Yet I do think might be some of the old ISPconfig settings acting up.
I am running CPanel and WHM, and every morning, I need to restart apache manually in order to work. Then it works for the whole day. It crashes I guess, but I don't know why. What logs do I need to check?
Today I got the devastating and heart-stopping news that all administraters fear most: "I'm looking at your website, and something's terribly wrong!!!"
The person went on to say that each page was just "filled with code ro something." When I finally saw it myself I discovered that my raw PHP pages were being served to the end user with no compilation --all of my top secret code; a real nightmare.
I went to look at the error logs and found that for several restarts Apache had not been compiling PHP.

WTH?
I could be WAAAY off base, but my first reaction was that I'd been hacked -- someone had found a way to disable PHP so they could find sensitive information in raw PHP pages. That could be totally wrong.
At any rate, even if I never learn why Apache sometimes will compile without PHP (and some other modules) without me telling it to do so, I'd like to be prepared for an embarassment like like this.
Is there any way, say, in the .htaccess file (or anywhere, anyway), I can tell Apache not to serve **ANY** pages unless the PHP module is present?

Server runs FreeBSD 6.1 and WHM/CPanel. Everything was working as usual, no changes were being made to the server, and all of a sudden all the web sites went down. WHM and CPanel and SSH remained accessible.
Restarting Apache (HTTPD) through WHM gives an error: "httpd has failed, please contact the sysadmin."
Rebooting the server didn't help, httpd still won't restart.
Attempting to do it via SSH gives this error:
server# /etc/rc.d/init.d/httpd restart /etc/rc.d/init.d/httpd restart: httpd not running, trying to start Syntax error on line 210 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/lib/mysql/libmysqlclient.so.14: Undefined symbol "gethostbyname_r" /etc/rc.d/init.d/httpd restart: httpd could not be started

I am having an issue with apache. Want to know how people are running huge forums having 700 800 users online at a time.
I am currently running a single forum having peak users upto 250, making posts and downloading files from within forum. Its running on dual opteron with 2 gig ram and its database is hosted on another cross connected dual opteron + 2 gig ram server.
Although there are enough resources, no load is there but still apache just crahsed and restarts after 4 min interval. As it seems apache gets out of resources and crashes.
how to allow apache to use more ram and cpu so that it simply don't crash.
I keep trying to restart Apache but it wont restart... I run a command line to restart it, but nothing happens. Here is what I have tried:

I am having a problem on my VPS. I am running the latest version of Apache on Windows Server 2K3, and after editing httpd.conf to allow virtual hosts (#Include /conf/extra/httpd-vhosts.conf) and trying to restart the service, an error appears saying the operation failed.
I have even tried restarting/starting the service via services.msc
If I am not using the default httpd.conf Apache will not restart at all... it is very strange. I have also tried doing a repair of the installation of Apache.
