Installation saltstack on RHEL CentOS-12213582

network

　　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 SALTSTACK REPOSITORY
　　2015.5 and later packages for RHEL 5, 6, and 7 are available in the SaltStack repository.
　　重要

　　The repository folder structure changed in the 2015.8.3>　　To install using the SaltStack repository:

• 　　Run one of the following commands based on your version to import the SaltStack repository key:
  　　Version 7:
  rpm --import https://repo.saltstack.com/yum/redhat/7/x86_64/latest/SALTSTACK-GPG-KEY.pub　　Version 6:
  rpm --import https://repo.saltstack.com/yum/redhat/6/x86_64/latest/SALTSTACK-GPG-KEY.pub　　Version 5:
  wget https://repo.saltstack.com/yum/redhat/5/x86_64/latest/SALTSTACK-EL5-GPG-KEY.pub　　
  rpm --import SALTSTACK-EL5-GPG-KEY.pub
  　　
  rm -f SALTSTACK-EL5-GPG-KEY.pub
  
• 　　Save the following file to /etc/yum.repos.d/saltstack.repo:
  　　Version 7 and 6:

• 　　Run sudo yum clean expire-cache.
  
• 　　Run sudo yum update.
  
• 　　Install the salt-minion, salt-master, or other Salt components:
  

• 　　yum install salt-master
  
• 　　yum install salt-minion
  
• 　　yum install salt-ssh
  
• 　　yum install salt-syndic
  
• 　　yum install salt-cloud
  

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

　　If installing on Red Hat Enterprise Linux 7 with disabled (not subscribed on) 'RHEL Server>[saltstack-repo]name=SaltStack repo for Red Hat Enterprise Linux $releaseverbaseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latestenabled=1gpgcheck=1gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/SALTSTACK-GPG-KEY.pub       https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/base/RPM-GPG-KEY-CentOS-7　　注解
　　systemd and python-systemd 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 REPOSITORY
　　Beginning with version 0.9.4, Salt has been available in EPEL. For RHEL/CentOS 5, Fedora COPR is a single community repository that provides Salt packages due to the removal from EPEL5.
　　注解

　　Packages in these repositories are built by community, and it can take a little while until the latest stable SaltStack>RHEL/CENTOS 6 AND 7, SCIENTIFIC LINUX, ETC.
　　警告
　　Salt 2015.8 is currently not available in EPEL due to unsatisfied dependencies: python-crypto 2.6.1 or higher, andpython-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 forRHEL/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.
安装稳定版
　　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
  

从 EPEL-TESTING 安装
　　When a new Salt>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使用PIP安装
　　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　　警告
　　如果从pip安装(或者使用 setup.py install 从源码安装)，需要注意 yum-utils 被Salt依赖，用于管理软件包。同样的，如果Python依赖没有安装，你需要额外安装库/工具来构建一些依赖。更多信息点 这里。
ZEROMQ 4
　　We recommend using ZeroMQ 4 where available. SaltStack provides ZeroMQ 4.0.5 and pyzmq 14.5.0 in theSaltStack Repository as well as a separate zeromq4 COPR 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.
　　警告
　　RHEL/CentOS 5 Users Using COPR repos on RHEL/CentOS 5 requires that the python-hashlib package be installed. Not having it present will result in checksum errors because YUM will not be able to process the SHA256 checksums used by COPR.
　　注解
　　For RHEL/CentOS 5 installations, if using the SaltStack repo or Fedora COPR to install Salt (as described above), then it is not necessary to enable the zeromq4 COPR, because those repositories already include ZeroMQ 4.
包管理
　　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.
