Medusa installation CentOS

CentOS 6-7

The following instructions are for installing Medusa on CentOS.

The installation should also be applicable to RHEL 6 and Fedora (12, 13, or 14) with minimal changes.

The installation assumes that you're not using the root user to install/run medusa - the entries for user:group throughout the document will have to be modified to match your user configuration.

1. Install IUS Community Project repository The repository is needed for recent Python versions

   For CentOS 6:

   sudo yum install https://centos6.iuscommunity.org/ius-release.rpm
   

   For Centos 7:

   sudo yum install https://centos7.iuscommunity.org/ius-release.rpm
   

2. Install prerequisites

    sudo yum install python36u wget git
   

   Install unrar:

   64bit

   wget https://www.rarlab.com/rar/rarlinux-x64-5.7.0.tar.gz
   tar -zxvf rarlinux-x64-5.7.0.tar.gz
   sudo cp -v rar/rar rar/unrar /usr/local/bin/
   

   32bit

   wget https://www.rarlab.com/rar/rarlinux-5.7.0.tar.gz
   tar -zxvf rarlinux-5.7.0.tar.gz
   sudo cp -v rar/rar rar/unrar /usr/local/bin/
   

3. Add new group and user

   sudo groupadd media
   sudo useradd -g media medusa
   

4. Clone medusa git repo

   sudo git clone https://github.com/pymedusa/Medusa.git /usr/share/medusa

5. Set correct ownership

   chown -R medusa:media /usr/share/medusa

For systemd (CentOS 7)

5. Copy systemd service

   sudo cp -v /usr/share/medusa/runscripts/init.systemd /etc/systemd/system/medusa.service
   

   Make sure your new service has correct permissions

   sudo chown root:root /etc/systemd/system/medusa.service
   sudo chmod 644 /etc/systemd/system/medusa.service

6. Enable, start, and then check the status of your new service

   sudo systemctl enable medusa
   sudo systemctl start medusa
   sudo systemctl status medusa

7. Add Medusa to startup (optional)

   sudo systemctl enable medusa.service
   

For Init Systems

5. Copy init file to system init

   sudo cp /usr/share/medusa/runscripts/init.fedora /etc/init.d/medusa

6. Make init file executable

   sudo chmod +x /etc/init.d/medusa

7. Modify init file

   sudo sed 's|/etc/sysconfig/sickbeard|/etc/sysconfig/medusa|' -i /etc/init.d/medusa

8. Create configuration file /etc/sysconfig/medusa with the following content

   # Medusa service configuration
   
   #run Medusa as
   SR_USER=media
   SR_HOME=/usr/share/medusa
   SR_DATA=/usr/share/medusa
   SR_PIDFILE=/usr/share/medusa/medusa.pid
   
   #gui address, eg: \${protocol}://\${host}:\${port}/home/
   protocol=http
   host='<<< hostname or IP >>>' #example host=mymachine
   port='<<<Desired Port>>>'     #example port=8081
   
   #leave blank if no username/password is required to access the gui
   username=
   password=
   
   #use nice, ionice, taskset to start Medusa
   nicecmd=
   #  example: nicecmd="nice -n 19 ionice -c3"

9. Add the medusa service to system services

   sudo chkconfig --add medusa

10. Configure medusa service to start on system startup

    sudo chkconfig medusa on

11. Start medusa service

    sudo service medusa start

All done, verify that Medusa is accessible at gui address, eg: http://your_ip:8081
