Installing BackupPC on CentOS

The definitive guide to installing...

or close enough

Part 1 of 3


I, recently, was able to install BackupPC on a new installation of CentOS 7 so I was able to go through my notes and put them in a coherent form.  Below is what I consider 'coherent.' :)   I decided to break this into 3 parts because, as I was writing, it became long.  The three parts are:  1. BackupPC Installation  2. Configuration of Server 3. Adding Linux and Apple Hosts

If something doesn't make sense, please post a comment.

  • I disable selinux.  If this isn't something you want to do and you know how to configure BackupPC with selinux enabled, please post a note and I'll make an addition to this list.
    • To disable selinux, edit the file:  /etc/sysconfig/selinux
      # This file controls the state of SELinux on the system.
      # SELINUX= can take one of these three values:
      #     enforcing - SELinux security policy is enforced.
      #     permissive - SELinux prints warnings instead of enforcing.
      #     disabled - No SELinux policy is loaded.
      # SELINUXTYPE= can take one of three values:
      #     targeted - Targeted processes are protected,
      #     minimum - Modification of targeted policy. Only selected processes are protected.
      #     mls - Multi Level Security protection.
    • Change the line that reads:  SELINUX=enforcing to SELINUX=disabled
    • Restart the computer

  • Install epel-release, backuppc, and sendmail, if not already installed
    yum install epel-release
    yum install backuppc sendmail

  • Add a BackupPC Admin user
    • From root, type: htpasswd /etc/BackupPC/apache.users  <<admin username>>
      • Example:  # htpasswd /etc/BackupPC/apache.users bpcadmin
    • When prompted, enter a password of your choice, twice
      # htpasswd /etc/BackupPC/apache.users bpcadmin
      New password: 
      Re-type new password: 
      Adding password for user bpcadmin
    • If you already know which users that will need access to BackupPC, you can add users this same way now or come back at a later time

  • With the Backup Drive mounted, create the folders, and change the permissions to allow the backuppc user access
    # mkdir /media/backups/BackupPC
    # mkdir /media/backups/BackupPC/pc
    # mkdir /media/backups/BackupPC/cpool
    # chown -R backuppc /media/backups/BackupPC/

  • Edit the BackupPC config file:  /etc/BackupPC/
    • Around line 300, look for:  $Conf{TopDir} and add the path where the backups will be stored.
      $Conf{TopDir} = '/media/backups/BackupPC/';
      $Conf{ConfDir} = '/etc/BackupPC/';
      $Conf{LogDir} = '/var/log/BackupPC';
      $Conf{InstallDir} = '/usr/share/BackupPC';
      $Conf{CgiDir} = '/usr/share/BackupPC/sbin/';
    • In the same file, scroll down further, around line 2030, and look for: $Conf{CgiAdminUsers}
    • Add the Admin user created above. This gives the Admin access to make changes via the Web Gui
      $Conf{CgiAdminUserGroup} = '';
      $Conf{CgiAdminUsers} = 'bpcadmin';
    • Save the file

  • Give the backuppc user permission to run anywhere on server
    • Run command as root:  visudo
    • Look for "Allow root to run any commands anywhere"
    • Below the line: root   ALL=(ALL)   ALL
    • Add:  backuppc    ALL=NOPASSWD:    ALL
      ## Allow root to run any commands anywhere
      root    ALL=(ALL)       ALL
      backuppc  ALL=NOPASSWD:   ALL
    • Save file

  • Start the BackupPC service
    # systemctl start backuppc.service
    • Helpful tip: If the service fails, run the following as root to view the errors
      # sudo -u backuppc /usr/share/BackupPC/bin/BackupPC -d

  • If Successful, log in to website with Admin user
  • Click 'Edit Config' and check the PingPath setting
    • If blank, change it to:  /usr/bin/ping

  • Click 'Email' and check the SendmailPath setting
    • If blank, change it to /usr/sbin/sendmail
