Center Server Administration Guide
Server control panel
For controlling technical aspects of the server (POWER ON, POWER OFF, RESET, etc.) a web-based control panel is used.
Login at https://manage.edis.at/vps, use "Login with email-address and password (new system)"
The server allows secure (ssh) logins only. From a Windows machine it is recommended to use the PuTTy tool as the ssh client.
Login at blackboxframework.org on port 22 with SSH selected.
Use the control panel for rebooting the server in case it shows any anomaly such as out-of memory error messages.
Then login to the server and start Redmine:
unicorn_rails -c config/unicorn.rb -E production -D
Certificates should be extended every 3 months.
service nginx stop
~/certbot-auto certonly --standalone -d forum.blackboxframework.org -d community.blackboxframework.org -d wiki.blackboxframework.org -d blackboxframework.org -d redmine.blackboxframework.org
service nginx start
For checking the web server status use:
service nginx status
MySql Database control panel
This can be used for example for creating backups of MySql databases. The administration tool is a php-based web application.
Login at http://220.127.116.11/phpmyadmin/
Before running the following bash command you should copy your public key to this server in order to login without password (modify it for user/serveradress you want to use):
ssh-copy-id -i .ssh/id_rsa.pub user@serveradress
bash command for backup of all files starting from /var/www (modify it for user/serveradress you want to use).
nohup tar -c /var/www 2>/dev/null | ssh user@serveradress "dd of=.../backup_of_var-www.tar" > result.out 2>&1 &
Cleaning up Disc Space
The servers running on the host produce a lot of log files, summing up to several gigabytes over time. Therefore it is required to check the available disc space periodically and to clean up old log files. The log files are located in /var/log. With the following commands it is easy to identify large log files, which are potential candidates for cleaning up.
