A VPS is locked when some operation (backup, migration, start / stop, etc.) with that VPS is in progress. You can determine which process is holding VPS #101 using the following command on the hardware node:
cat /vz/lock/101.lck
You can kill that process if needed, but make sure that the process is really killed. If there is no process with that PID on the node, just remove the lockfile.
If you need to go back to apache 1.3 after installing apache 2, you’ll need to do the following:
1) Restore the old httpd.conf file:
cp -f /etc/httpd/conf/httpd.conf.1.3.backup /etc/httpd/conf/httpd.conf
2) Get DirectAdmin to use the old httpd.conf files for the users. Edit the /usr/local/directadmin/conf/directadmin.conf file and change apache_ver=2.0 to apache_ver=1.3. Then type
echo “action=rewrite&value=ips” >> /usr/local/directadmin/data/task.queue
echo “action=rewrite&value=httpd” >> /usr/local/directadmin/data/task.queue
echo “action=directadmin&value=restart” >> /usr/local/directadmin/data/task.queue
3) Now you can recompile apache 1.3
rm -f /usr/lib/apache/*
cd /usr/local/directadmin/customapache
./build clean
./build all
4) Fix the modules link:
cd /etc/httpd
rm -f modules
ln -s /usr/lib/apache modules
5) Restore the old boot script:
FreeBSD:
cp -f /usr/local/directadmin/customapache/httpd_freebsd /usr/local/etc/rc.d/httpd
chmod 755 /usr/local/etc/rc.d/httpd
/usr/local/etc/rc.d/httpd restart
RedHat:
cp -f /usr/local/directadmin/customapache/httpd /etc/init.d/httpd
chmod 755 /etc/init.d/httpd
/etc/init.d/httpd restart
If you need to update your DirectAdmin license manually, you can do so by running the following commands:
cd /usr/local/directadmin/scripts
./getLicense.sh 123 1234
service directadmin restart
Where 123 and 1234 are your Client ID and License ID, respectively. If there are errrors extracting the update.tar.gz file, then run:
head -n 1 /usr/local/directadmin/conf/license.key
to search for an error. If there is an readable error inside the file, double check the IP you are using matches the IP in the license on our system. Also check that it’s active in our clients section. Failing that, you’ll need to contact [email protected] to get your license activated or updated.
If you have multiple IPs on your device and wget is binding to the incorrect one, you can specify the IP to bind to by adding it as the last argument:
cd /usr/local/directadmin/scripts
./getLicense.sh 123 1234 1.2.3.4
service directadmin restart
Here is the steps to backup individual domain on Plesk. I’ve tested. It works.
1) backup the domain
#pleskbackup -v domains yourdomainname.com backupfilename.bkp
2) Then create a map file
#pleskrestore –create-map backupfilename.bkp -map yourmapfilename
map file should be like that below. if not, edit it.
++++++++++++++++++++++++++++++++++++++++++++++++++ +++++
[thisdomain’sclientname] # Client account name
yourdomainname.com 11.22.33.44 # IP address
mysql::@localhost:3306
++++++++++++++++++++++++++++++++++++++++++++++++++ +++++
Then you can restore it with the following command.
#pleskrestore –restore backupfilename.bkp -level domains -map yourmapfilename
This backup will back up everything including mailboxes and database.
How to uninstall RVSkin?
Run this command:
perl /root/rvadmin/uninstall.pl
Terminate rvadmin account from WHM
Reinstall rvadmin
mkdir /root/rvadmin; cd /root/rvadmin; wget http://download.rvglobalsoft.com/download.php/download/rvskin-auto/saveto/rvauto.tar.bz2; bunzip2 -d rvauto.tar.bz2; tar -xvf rvauto.tar; perl /root/rvadmin/auto_rvskin.pl
The following example shows how to restore the mysql.preupgrade.dump.gz backup file.
gunzip /var/lib/psa/dumps/mysql.preupgrade.dump.gz
mysql -uadmin -p`cat /etc/psa/.psa.shadow` -e”DROP DATABASE psa;”
mysql -uadmin -p`cat /etc/psa/.psa.shadow` < /var/lib/psa/dumps/mysql.preupgrade.dump
Actually standard daily backup file includes three databases:
* psa
* horde
* mysql
That is why the following error message will appear when you performed the latest command:
ERROR 1050 at line 3165: Table ‘horde_categories’ already exists
This happens because only the “psa” database was restored. However, if you want to restore all
three databases, then you have to delete them using “DROP DATABASE” sql command.
Also, make sure that you are always restoring the latest backup file.
