RHEL / CentOS / Scientific Linux / Amazon Linux / Oracle Linux

Salt should work properly with all mainstream derivatives of Red Hat Enterprise Linux, including CentOS, Scientific Linux, Oracle Linux, and Amazon Linux. Report any bugs or issues on the issue tracker.

Installation from the Official SaltStack Repository

Packages for Redhat, CentOS, and Amazon Linux are available in the SaltStack Repository.

Note

As of 2015.8.0, EPEL repository is no longer required for installing on RHEL systems. SaltStack repository provides all needed dependencies.

Warning

If installing on Red Hat Enterprise Linux 7 with disabled (not subscribed on) 'RHEL Server Releases' or 'RHEL Server Optional Channel' repositories, append CentOS 7 GPG key URL to SaltStack yum repository configuration to install required base packages:

[saltstack-repo]
name=SaltStack repo for Red Hat Enterprise Linux $releasever
baseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest
enabled=1
gpgcheck=1
gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/SALTSTACK-GPG-KEY.pub
       https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/base/RPM-GPG-KEY-CentOS-7

Note

systemd and systemd-python are required by Salt, but are not installed by the Red Hat 7 @base installation or by the Salt installation. These dependencies might need to be installed before Salt.

Installation from the Community-Maintained Repository

Beginning with version 0.9.4, Salt has been available in EPEL.

Note

Packages in this repository are built by community, and it can take a little while until the latest stable SaltStack release become available.

RHEL/CentOS 6 and 7, Scientific Linux, etc.

Warning

Salt 2015.8 is currently not available in EPEL due to unsatisfied dependencies: python-crypto 2.6.1 or higher, and python-tornado version 4.2.1 or higher. These packages are not currently available in EPEL for Red Hat Enterprise Linux 6 and 7.

Enabling EPEL

If the EPEL repository is not installed on your system, you can download the RPM for RHEL/CentOS 6 or for RHEL/CentOS 7 and install it using the following command:

rpm -Uvh epel-release-X-Y.rpm

Replace epel-release-X-Y.rpm with the appropriate filename.

Installing Stable Release

Salt is packaged separately for the minion and the master. It is necessary to install only the appropriate package for the role the machine will play. Typically, there will be one master and multiple minions.

  • yum install salt-master

  • yum install salt-minion

  • yum install salt-ssh

  • yum install salt-syndic

  • yum install salt-cloud

Installing from epel-testing

When a new Salt release is packaged, it is first admitted into the epel-testing repository, before being moved to the stable EPEL repository.

To install from epel-testing, use the enablerepo argument for yum:

yum --enablerepo=epel-testing install salt-minion

Installation Using pip

Since Salt is on PyPI, it can be installed using pip, though most users prefer to install using RPM packages (which can be installed from EPEL).

Installing from pip has a few additional requirements:

  • Install the group 'Development Tools', yum groupinstall 'Development Tools'

  • Install the 'zeromq-devel' package if it fails on linking against that afterwards as well.

A pip install does not make the init scripts or the /etc/salt directory, and you will need to provide your own systemd service unit.

Installation from pip:

pip install salt

Warning

If installing from pip (or from source using setup.py install), be advised that the yum-utils package is needed for Salt to manage packages. Also, if the Python dependencies are not already installed, then you will need additional libraries/tools installed to build some of them. More information on this can be found here.

ZeroMQ 4

We recommend using ZeroMQ 4 where available. SaltStack provides ZeroMQ 4.0.5 and pyzmq 14.5.0 in the SaltStack Repository.

If this repository is added before Salt is installed, then installing either salt-master or salt-minion will automatically pull in ZeroMQ 4.0.5, and additional steps to upgrade ZeroMQ and pyzmq are unnecessary.

Package Management

Salt's interface to yum makes heavy use of the repoquery utility, from the yum-utils package. This package will be installed as a dependency if salt is installed via EPEL. However, if salt has been installed using pip, or a host is being managed using salt-ssh, then as of version 2014.7.0 yum-utils will be installed automatically to satisfy this dependency.

Post-installation tasks

Master

To have the Master start automatically at boot time:

RHEL/CentOS 5 and 6

chkconfig salt-master on

RHEL/CentOS 7

systemctl enable salt-master.service

To start the Master:

RHEL/CentOS 5 and 6

service salt-master start

RHEL/CentOS 7

systemctl start salt-master.service

Minion

To have the Minion start automatically at boot time:

RHEL/CentOS 5 and 6

chkconfig salt-minion on

RHEL/CentOS 7

systemctl enable salt-minion.service

To start the Minion:

RHEL/CentOS 5 and 6

service salt-minion start

RHEL/CentOS 7

systemctl start salt-minion.service

Now go to the Configuring Salt page.
