Apache / Re: CustomLog bytes
« on: December 07, 2019, 07:02:14 PM »
I think they intend to add the feature of logging bytes in/out for individual domains for http/https at some point. This does require mod_logio which isn't enabled by default right now. At the moment it just fills a log file with the word "bytes." It's been the better part of a year they should either complete the feature or comment out the CustomLog. No sense in making garbage files that grow.

Backup / Re: Restore backup
« on: November 30, 2019, 10:11:08 PM »
All you should really have to do is "cp -a" the user's selected backup directory to their home directory "chown -R" it to the user then drop their current database(s) and attach the corresponding backup one(s).

CentOS-WebPanel Bugs / Re: Default page changed to index.html on all sites!

I had the same problem and resolution. Not too happy about it, esp after the surprise Nginx disabling.

ok first ssh onto the server console and type slabtop to look to see how much memory dentry is using.

You don't want to run this with mysql active as it can corrupt databases but this command basically drops dentry cache. I shut down my web server too. If you use a different web server you should probably stop that too. Basically kill all the disk writes you can while this is running. I have 48GB of RAM and I'll run this around 35GB used and it takes a couple min. Ya might also want to adjust the swapiness of your system cause ideally servers shouldn't swap.

I've always assumed that any backup would be an rsync of the target directory regardless of remote or local.

your provider sets the rDNS you'd need to contact them to give the rDNS pointer a name.

Backup / Re: backup is not working
« on: March 31, 2018, 11:08:27 PM »
If you're using CentOS 6 at some point the backup script updated to use a newer php and it didn't update the cron job that ran the backup script. Run:
#> cat /etc/cron.daily/cwp
If you see something like:
/usr/local/cwp/php -d max_execution_time=1000000 -q /usr/local/cwpsrv/htdocs/resources/admin/include/cron_backup.php
try running it, it'll probably error out and not execute. If this happens try changing it to:
/usr/local/cwp/php71/bin/php -d max_execution_time=1000000 -q /usr/local/cwpsrv/htdocs/resources/admin/include/cron_backup.php
and run it again if it works, update the cronjob.

CentOS 6 Problems / Re: high RAM consumption in idle mode CWP
« on: March 31, 2018, 11:01:14 PM »
Which version or CWP are you using? I'm using
CWP version: 0.9.8.398
and it's gotten much better. Seems to stem from a leaky version of nss that causes curl calls to query none existent files the results of those queries are stored in dentry cache IIRC.
try looking at slabtop from the command line. if the dentry cache is HUGE this is your problem. Long term solution is to make sure your yums are all up to date and you're running the most current version of CWP. Short term solution is:
service httpd stop
service mysqld stop
sync && echo 2 > /proc/sys/vm/drop_caches
service mysqld start
service httpd start
This will drop your dentry cache but you want to make sure no services are writing to disk when you run it because they'll stop mid write. Also just a warning, it can take a sec for it to run.

« on: January 03, 2018, 02:49:38 AM »If gmail and the like are marking it spa, make sure your hosting company has a reverse DNS entry setup for your server. It's not difficult but your colo company needs to do it for you.

well, you can always:
adduser [username]
passwd [username]
... but this does not add them to the panel, set up domain, website, etc, pretty much just gives them shell access.
