Virtual TapeServer 6.03.41 Installation Guide

102 | Troubleshooting
The Apache web server is responsible for running the VTS web interface. To verify that
Apache is running:
/etc/init.d/httpd status
A message similar to the following should be displayed:
httpd (pid 25380 25015 25014 25013 25012 25011) is running...
Use the following commands, respectively, to stop, start, or restart the database (halt VTS
before issuing these commands):
• /etc/init.d/httpd stop
• /etc/init.d/httpd start
• /etc/init.d/httpd restart
You can also reboot VTS to attempt to solve the problem.
