Server Restart
Dec 18, 2007
I'm on my first VPS with Virtuozzo / WHM and I'm wondering about what some general guidelines regarding best practices are in regards to restarting services and or the server. Specifically, I'm wondering what a good time frame it to restart the server and sevices.
I've been told VZ doesn't need to be restarted, but I figured that by restarting VZ, I restart everything at once... is this bad? How often should I do this or not do this?
Alternatively, if I just restart specific services, what is your experience on a good timeline and what services are important to restart?
I've read that mysql doesn't need to be restarted, but am wondering EXIM, http server, dns server, pop3 server, imap server, etc.... specifically what good schedule would be regarding restarting.
I'm simply trying to avoid issues that may occur due to not restarting and trying to be proactive as my clients are extremely important to me... ...

I don't know if this is possible after searching on the internet for solutions. Here is the problem. I recently logged off my colocated server 2 days ago, and have been trying to log into it again like I always do using remote desktop. Each time I try it gives me this following error: "This computer can't connect to the remote computer. Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator."
I've had this server colocated for about 5 months now and I've never had any issues connecting remotely to it. Seems like Remote Desktop got broken somehow, or it's being blocked? I am an admin with logins/passwords etc. The OS is Windows Server 2003 R2, I'm not connected to a remote reboot console. I don't want to have to call the data center for remote hands on support for a restart if that's not going to fix the issue, from what I've heard they charge quite a bit.

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?

Anyone know a good script that I can run with cron or something? Mysql seems to be the #1 problem with a lot of my web sites, a restart usually fixes it right away for me, but I can't keep restarting my servers everyday manually.

What could I fix by trying to start mysql server, recieve following errors:
plesk interface:
Code:
Failed to restart the "mysql" service.
Cannot start/stop/restart service: Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql restart
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop mysql ; start mysql. The restart(8) utility is also available.
start: Job failed to start
from the console:
Code:
sudo service mysql start
start: Job failed to start
Code:
mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa

If you rename a domain, fail2ban will stop working, since it still tries to open the old path the the web access log.
One workaround is to restart the server after renaming the domain, then fail2ban paths are updated.
I'm using plesk 12.0.18.

Is it ok to simply delete these files? If so, will they recreate

I'm running Apache 2.0.52 on a CentOS 4.4 server.
Running two static sites and one CMS.
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'm having problems with Apache 2.0.54 on my Debian server. The command "apache2ctl restart" will not work properly. Let me explain. Whenever I run "apache2ctl restart" Apache will tell me it's running with no problems while it actually isn't. I run "apache2ctl start" and it tells me that httpd is already running according to a PID.
When I need to restart Apache I need to go and run "apache2ctl stop" and "apache2ctl start" which seems to work effectively. I tried recoding the system to run these two commands in the Perl backend of my web hosting control panel, but these two commands don't work since they seem to run at the same time.
So my question is this: how can I get the "apache2ctl restart" command to work again? Or better yet, how do I get Perl to run the "apache2ctl stop" and "apache2ctl start" commands without having them being run simultaneously?
