General info

This section describes cBackup manual installation on Linux operating system from TAR.GZ source with Apache or Nginx web server. If you are system administrator who likes to control every step and every bit of process - here's your guide.

Update system and disable SELinux

Make sure system has all latest updates and security addons (like SELinux) either are disabled, permissive or properly set up to work with third-party software. Firewall should be adjusted to serve HTTP/HTTPS traffic.

Install required software

To proceed you'll need: wget, git, net-snmp and jre (or any other java 8 runtime like openjdk).

Install web server, MySQL server and PHP 7

Setup LAMP/LEMP (Apache or NGinx in accordance) bundle: web server, PHP 7 and MySQL-based database server. For MySQL you are free to choose from Oracle MySQL, Percona or MariaDB based on MySQL 5.5 or higher. For PHP 7 you will need following extensions: php-gmp, php-zip, php-intl, php-ssh2, php-snmp, php-mbstring, php-mcrypt, php-bcmath, php-cli and php-curl. If you are installing PHP as a FastCGI, don't forget to install php-fpm. Make sure the whole bundle is up, placed in autostart, running and serving PHP documents properly. Prepare your web root and proper FQDN for your cBackup installation.

Prepare user and database for cBackup. You want to use MySQL console to complete this task:

CREATE DATABASE cbackup CHARSET utf8 COLLATE utf8_general_ci;
CREATE USER 'cbackup'@'localhost' IDENTIFIED BY 'mypassword';
GRANT USAGE ON *.* TO cbackup@localhost;
GRANT ALL PRIVILEGES ON cbackup.* TO cbackup@localhost;

Download archive and unpack it

You may want to change path where you cBackup is downloaded and extracted.

wget -O cbackup.tar.gz ""
tar xvf cbackup.tar.gz

Adjust file owner for your installation

chown your extracted files/folder adjusting owner in accorance with your web server. E.g. it could be apache:apache or nginx:nginx for different servers. In case of using PHP-FPM, make sure which user is used for running FastCGI process.

Add cbackup system group and user

Replace {DIRECTORY} with your cbackup installation folder and {apache} with your web server or FastCGI process owner group. This will create cbackup system user with supplementary group of your web server.

groupadd -r cbackup
useradd -r -g cbackup -G {apache} -d {DIRECTORY} -s /bin/bash -c "cBackup System User" cbackup

Place supplementary configurations

There are several subfolders in the folder ./install/system with configurations for systemd, sysvinit, logrotate, sudoers, firewalld and rsyslog. It's mandatory to configure at least two things:

  • Sudoers
    Copy cbackup file to your /etc/sudoers.d directory from ./install/system/centos/systemctl/etc/sudoers.d or from ./install/system/centos/initd/etc/sudoers.d depending if your operating system is controlled by systemd or sysvinit

  • System daemon, systemctl
    For systemctl copy cbackup.service unit file from ./install/system/centos/systemctl/usr/lib/systemd/system to your systemd/system folder. Don't forget to adjust path to cbackup.jar file in the unit file itself.

  • System daemon, sysvinit
    For SysV, make a symlink to cbackup.jar into your init.d or rc.d like ln -s /opt/cbackup/bin/cbackup.jar /etc/init.d/cbackup. Now you can control it as a regular system service, e.g. /etc/init.d/cbackup status.

Setup web server

Point web server wwwroot to the folder web in the unpacked cBackup installation. Under no circumstances any files or folders above the web folder should be accessible. Actually, there's a check in the setup wizard which won't allow you to proceed unless installation is secured.

Reload services

systemctl daemon-reload
systemctl restart httpd

Start cBackup web setup

Open up you browser pointing to and compele setup process, providing promted data to wizard. Please note, that when setup is complete, installation directories are removed and if you have forgotten to copy system configurations like sudoers or systemctl unit file, extract them from archive again.

Register cbackup daemon

Use systemctl enable cbackup or chkconfig cbackup on for systemctl and sysvinit in accordance, to make cBackup daemon start with server automatically on boot.
