Download and Install the Linux Agent

Installing the agent on a server allows actions such as registering the agent as a source with the IBM Cloud Backup and Recovery or performing file-level recovery.

Install the Agent

Navigate to Data Protection > Sources.
Click Download Backup agent.

The Download Agents window appears.
Follow the installation instructions for the corresponding installer package.
Configure the firewall and ports as necessary. For more information, see Manage Firewall Ports.

Install RPM, Debian or SUSE RPM Installer Package

The following table explains the action to be performed for installing the RPM, Debian or SUSE installer package:

In the following commands, replace the Backup agent version with the desired agent version.

Action	How to
Download the Agent installer	From the Download Agents window, based on your Linux distribution, select RPM, Debian, or SUSE RPM and download it to the server you want to protect.
Navigate to the downloaded directory	As the root user with local system privileges on that server, change the directory to the location of the installer package.
Install the Custom certificates	LINUX If you are using a IBM Cloud Backup and Recovery certificate then run the following commands to install the user certificate followed by agent installation: export ENFORCE_USE_CUSTOM_CERTS=true && export AGENT_CERT_FILE= If you are using a user certificate then run the following commands to install the user certificate followed by agent installation: export ENFORCE_USE_CUSTOM_CERTS=true && export USE_THIRD_PARTY_CERTS=true && export ROOT_CA_FILE= && export PRIVATE_KEY_FILE= && export CERT_CHAIN_FILE=
Install the Agent	Run the following command depending on the installer package: * RPM: `rpm -i el-cohesity-agent--1.x86_64.rpm` or `yum localinstall ./el-cohesityagent-7.2-1.x86_64.rpm` * Debian: `dpkg -i cohesity-agent_-1_amd64.deb` * SUSE RPM: `rpm -i cohesity-agent--1.x86_64.rpm`
Install the agent as root user	Run the executable file with the following command syntax: /<path_to_installer_file> -- --install -c 0 -S root -G root Followings are the command options in details: 1. -S this is the user to run the agent, specify root. 2. -G this is the group permission the Agent will use for files and directories installed by the agent, specify root. 3. -c this boolean switch controls if the OS user and group should be created. 0 means do not create the OS user and group, 1 means the agent installation will create the specified OS user and group. (When choose to run with the root user, specify ‘-c 0’ as ‘root’ already exists)
Install the agent as non-root user	To start the service as a non-root user, create a new user or use an existing user with sudo permission and run the following command: * RPM: `export COHESITYUSER=<username> ; rpm -i el-cohesity-agent--1.x86_64` * Debian: `COHESITYUSER=<username> dpkg -i cohesity-agent_-1_amd64` * SUSE RPM: `export COHESITYUSER=<username> rpm -i cohesity-agent--1.x86_64` Where, `<username>` is the user name with sudo permission. By default, the installation uses the root user permission for all the files, and the service is started as root. Therefore, it is required to add non-root users to the sudoers list by making the following changes in the `/etc/sudoers` file: `<user_name> ALL=(ALL) NOPASSWD:ALL` `Defaults:<user_name> !requiretty` An example of the sudoers file is as given below: dgoble ALL=(ALL) NOPASSWD:ALL Defaults:dgoble !requiretty cohbackup ALL=(ALL) NOPASSWD:ALL Defaults:cohbackup !requiretty You can add sudo privileges for non-root users using the syntax given below: `<user_name> ALL=(ALL) NOPASSWD:/path/to/command1, /path/to/command2, /path/to/command3` Remove `NOPASSWD` from the command above if you do not want to authenticate every sudo commands with password. The example below shows the sudo commands for user cohesityagent: cohesityagent ALL=NOPASSWD: /bin/mount,/bin/umount,/bin/chmod,/bin/chown,/bin/hostname,/bin/mkdir,/bin/rm,/usr/bin/tee,/usr/bin/stat,/bin/cp,/bin/sed,/usr/bin/touch,/sbin/blkid,/usr/bin/lsof,/bin/ls,/sbin/losetup,/sbin/dmsetup,/usr/bin/rsync,/usr/bin/timeout,/usr/bin/getfacl,/usr/bin/setfacl,/tmp/installer_ch_cohesity_linux_agent,/home/cohesityagent/installer,/home/cohesityagent/cohesityagent/data/agent/tmp/installer_ch_cohesity_linux_agent,/bin/systemctl,/home/cohesityagent/cohesityagent/software/crux/bin/cohesity_linux_agent.sh The actual paths for each command may vary in each system. IBM Cloud Backup and Recovery keeps adding or removing commands across releases.
Location	* Installation directory: `/opt/cohesity` * Log file: `/var/log/cohesity`

Install script installer package

The following table explains the action to be performed for installing the script installer package:

In the following commands, replace the Backup agent version with the desired agent version.

Action	How to
Download the Agent installer	From the Download Agents window, based on your Linux distribution, select Script Installer and download it to the server you want to protect.
Navigate to the downloaded directory	As the root user with local system privileges on that server, change the directory to the location of the installer package. For SLES 11 SP4, installing the agent as the root user is required.
Make the installer executable	Make the installer executable, for example: `chmod +x cohesity_agent__linux_x64_installer`
Install the Agent	Run the executable: sudo /cohesity_agent_6.6.0d_u2_linux_x64_installer – --install
Location	* Installation directory:`/home/<username>/cohesityagent` or `/root/cohesityagent` * Log file: `/home/cohesityagent/cohesityagent/logs` You can specify the option `-log-dir <installtion_path>` to specify the directory path where the agent logs will be saved. If this option is not provided, the logs will be saved in the default path

Agent startup behavior following a machine reboot:

CentOS and RedHat (distributions with the "systemd" init system) - The agent starts automatically.
Ubuntu (distributions with the "upstart" init system) - The agent starts automatically.

If a Linux server's /etc/sudoers file is managed by a deployment engine such as Chef, Puppet or others, this could impact IBM Cloud Backup and Recovery's interaction with servers that have the Linux agent installed. Take the corresponding actions below:

Agent Installation - User type	Action required
As default cohesityagent user	The Backup agent is installed using the cohesityagent user by default. For default installations, the cohesityagent is created by the installer. During installation, the installer updates the `/etc/sudoers` file to allow cohesityagent sudo and no-tty sudo access. Ensure the following settings in the /etc/sudoers file for the cohesityagent user are preserved: cohesityagent ALL=(ALL) NOPASSWD:ALL Defaults:cohesityagent !requiretty An example of the sudoers file is as given below: #includedir /etc/sudoers.d dgoble ALL=(ALL) NOPASSWD:ALL cohbackup ALL=(ALL) NOPASSWD:ALL Defaults:cohbackup !requiretty
As non default user, example foo	Ensure the above settings in the `/etc/sudoers` file for the foo user are preserved by replacing the occurrences of cohesityagent with foo.
As root user	No changes required

cohesity_linux_agent.sh

The table lists how cohesity_linux_agent.sh interacts with various init systems to issue start/stop/status commands.

If IBM Cloud Backup and Recovery does not detect any of the init systems, the installer uses the undetected init system commands.

init system	Commands
systemd	sudo systemctl start cohesity-agent sudo systemctl stop cohesity-agent sudo systemctl status cohesity-agent
upstart	sudo initctl start cohesity-agent sudo initctl stop cohesity-agent sudo initctl status cohesity-agent
SysV	sudo /etc/init.d/cohesity-agent start sudo /etc/init.d/cohesity-agent stop sudo /etc/init.d/cohesity-agent status
undetected	sudo /etc/init.d/cohesity-agent start sudo /etc/init.d/cohesity-agent stop sudo /etc/init.d/cohesity-agent status

Download and Install the Backup agent on RHV Hosts

IBM Cloud Supports RHV only until version 6.8.1. While you can still protect your RHV sources, the IBM Cloud Support team will not provide assistance.

Ensure you install the Backup agent on any RHV hosts that you want IBM Cloud Backup and Recovery to protect. For installing the agent on RHV hosts, follow the steps described in the Download and Install the Backup agent on Linux Physical Servers” section based on the Linux distribution

Run the following command on all the RHV hosts after they are connected and configured by the oVirt Manager:

# iptables -I INPUT `iptables -L INPUT --line-numbers | grep REJECT | awk '{ print $1 }'` -p tcp --dport 50051 -j ACCEPT

# service iptables save # service iptables restart

If the firewall is enabled on RHV 4.1 hosts, open the following port 50051 to accept traffic.

To open the ports, run the following command:

firewall-cmd --permanent --add-port 50051/tcp

Linux Script Installer Options

The Backup agent installer has the following options available.

Option	Description
--agent-options, -a [options]	Options to pass to the Backup agent. Used with single mode operation only.
--create-user, -c [0\|1]	Whether to create `--service-user` or not. [Default: 1] Used with `--install` option only.
--debug, -d	Enable shell script debugging with set `-x` [Default: off]
--full-uninstall, -U	Uninstall the Backup agent including service-user account and its home directory contents. Destructive operation. Use with care.
--help, -h	Print this help.
--install, -i	Install/uninstall the Backup agent.
--install-dir, -I [dir]	Backup agent installation dir. [Default: `/home/<username>/cohesityagent or /root/cohesityagent`]
--install-log-file, -L [file]	Filename where installer logs should be saved. [Default: /tmp/cohesity_agent_installer_<time_in_seconds>_ .log]
--log-dir	Backup agent log installation directory. [Default: `/home/cohesityagent/cohesityagent/logs`]
--service-group, -G [group]	Groupname to use for service. [Default: `cohesityagent`]
--service-user, -S [user]	Username to use for service. [Default: `cohesityagent`]
--single-mode, -s	Install the Backup agent for single mode operation. This installs the agent for one time usage/run only. It does not install the Agent to run as service or daemon to run continuously. This copies all required binaries/files to a location and runs the agent. Example use case: You want to recover files to a Linux VM. IBM Cloud Backup and Recovery pushes the Backup agent and starts it. After performing the usual file/folder recovery by talking to Backup agent and file copying is done, the Agent is removed. The agent is not installed to run as service. It runs for the duration of the recover task only.
--skip-lvm-check	1 - Skip LVM related checks during installation and start the agent in non-lvm mode (only file-based backup will be supported). 0 - Flag is not set. The default value is 0.
--skip-mountpoint-check	Skip checks performed on installation directory's filesystem mountpoint.
--target	Extract directly to a target directory. Directory path can be either absolute or relative. [Default: `/tmp`]
--update-uninstall, -u	Uninstall the Backup agent. Preserve user, group and agent config. Useful when upgrading software.
--yes-all, -y	Accept 'yes' answer to all questions in installer. [Default: off] This is useful for performing silent install/uninstall.

Install the Backup agent to run with the Root User

Follow the steps below to install the Backup agent to run with the root user:

In the following command, replace the Backup agent version with the desired agent version.

For example, run the following command: sudo ./cohesity_agent__linux_x64_installer -- --install -S root -G root -c 0 -I /opt -y

The above example does the following:

-S root -G root sets user "root:root" user:group for the agent.
-c 0 instructs the installer that user root already exists on the system, so do not create it.
-I /opt installs the agent in the /opt directory. If you do not specify the directory, then the default home directory of the user will be used, /root/ in this case.

Sudo Privileges for Linux Users

The Linux system administrator can allowlist set of commands that do not need the root rights to be executed from the Backup agent deployed on the Linux servers.

The following tables list the commands that can be allowlisted for Oracle database, volume backups, and file restores for the Backup agent.

Oracle Database

Argument	Default Behavior	Allowlist Commands
--skip-oracle-check	The default value is 0. We will allowlist commands required by Oracle database.	`mkdir` `rm` `tee` `stat` `cp` `srvctl (from Oracle home)`
If set to 1, we will not add any commands to the allowlist.

Volume Backup

Argument	Default Behavior	Allowlist Commands
--skip-lvm-check	The default value is 0. We will allowlist commands required by volume backup.	`lvs` `vgs` `lvcreate` `vgcreate`
If set to 1, we will not add any commands to the allowlist.

File Restore

Argument	Default Behavior	Allowlist Commands
--skip-restore-check	The default value is 0. We will allowlist commands required by file restore.	`blkid` `lsof` `ls` `losetup` `dmsetup` `rsync` `timeout`
If set to 1, we will not add any commands to the allowlist.

During a Linux agent upgrade: If NOPASSWD:ALL entry is present in the sudoers file, then all commands can be executed without the root rights. If NOPASSWD:ALL entry is removed from the sudoers file, then you can add the commands listed in the table above for allowlisting.
