saltstack是一个新的基础平台管理工具; C/S架构
https://docs.saltstack.com/en/latest/topics/installation/index.html
优点:
1.安装、部署简单,可快速启动服务
2.可支撑管理上万台服务器的规模
3.传输数据基于ZeroMQ(轻量级消息队列),传输数据并发、快速
4.支持API及自定义模块,可以通过Python轻松扩展
依赖:
DEPENDENCIES
Salt should run on any Unix-like platform so long as the dependencies are met.
Python 2.6 >= 2.6 <3.0
msgpack-python - High-performance message interchange format
YAML - Python YAML bindings
Jinja2 - parsing Salt States (configurable in the master settings)
MarkupSafe - Implements a XML/HTML/XHTML Markup safe string for Python
apache-libcloud - Python lib for interacting with many of the popular cloud service providers using a unified API
Requests - HTTP library
Tornado - Web framework and asynchronous networking library
futures - Backport of the concurrent.futures package from Python 3.2
端口:
4505:为salt的消息发布专用端口 //在monion端ss -e会发现一直和master的4505端口保持链接,用于和客户端的长连接,保证master端和minion端的消息通信正常
4506:用于文件服务的传输端口,进行认证等
环境:[root@salt-master salt]# salt '*' grains.item os osrelease salt-master: ---------- os: CentOS osrelease: 7.2.1511hddcluster3: ---------- os: RedHat osrelease: 7.3hddcluster2: ---------- os: RedHat osrelease: 7.2hddcluster4: ---------- os: RedHat osrelease: 7.2salt-minion01: ---------- os: CentOS osrelease: 6.7hddcluster1: ---------- os: RedHat osrelease: 7.2[root@salt-master salt]#
salt-master服务端主机:详细安装请参考官网,正常情况yum是可以安装saltstack的、服务器端安装master和minion:yum install salt-masteryum install salt-minion查看服务端安装了什么:[root@salt-master ~]# rpm -ql salt-master/etc/salt/master/etc/salt/master.d/etc/salt/pki/master/usr/bin/salt/usr/bin/salt-cp/usr/bin/salt-key/usr/bin/salt-master/usr/bin/salt-run/usr/bin/salt-unity/usr/lib/systemd/system/salt-master.service/usr/share/man/man1/salt-cp.1.gz/usr/share/man/man1/salt-key.1.gz/usr/share/man/man1/salt-master.1.gz/usr/share/man/man1/salt-run.1.gz/usr/share/man/man1/salt-unity.1.gz/usr/share/man/man7/salt.7.gz/var/log/salt/master[root@salt-master ~]# rpm -ql salt-minion/etc/salt/minion/etc/salt/minion.d/etc/salt/pki/minion/etc/salt/proxy/usr/bin/salt-call/usr/bin/salt-minion/usr/bin/salt-proxy/usr/lib/systemd/system/salt-minion.service/usr/share/man/man1/salt-call.1.gz/usr/share/man/man1/salt-minion.1.gz/usr/share/man/man1/salt-proxy.1.gz/var/log/salt/minion修改简单的配置:vi /etc/salt/master#interface: 0.0.0.0改为interface: 10.0.0.177 //10.0.0.177为服务器的本机地址到此入门的安装配置就已经完毕,下面说minion端的安装配置了
客户端只安装minion包括hddcluster1、hddcluster2、hddcluster3、hddcluster4、salt-minion01:yum install salt-minion[root@salt-minion01 ~]# rpm -ql salt-minion/etc/rc.d/init.d/salt-minion/etc/salt/minion/etc/salt/minion.d/etc/salt/pki/minion/etc/salt/proxy/usr/bin/salt-call/usr/bin/salt-minion/usr/bin/salt-proxy/usr/share/man/man1/salt-call.1.gz/usr/share/man/man1/salt-minion.1.gz/usr/share/man/man1/salt-proxy.1.gz/var/log/salt/minionroot@salt-minion01 ~]#vim /etc/salt/minion#master: salt改为:master: 10.0.0.177
