自动化运维工具Saltstack的部署

一、saltstack搭建

配置yum源:
Master 在/var/www/html/添加salt

Minion：server2和server3
完善yum源:

[rhel-source]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
baseurl=http://172.25.7.250/source6.5
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[salt]
name=saltstack
baseurl=http://172.25.7.250/salt
enabled=1
gpgcheck=0

server1部署master,server2部署minion

[root@server1 ~]# yum  install salt-master -y
[root@server1 ~]# /etc/init.d/salt-master start
[root@server2 salt]# yum  install salt-minion -y
[root@server2 salt]# vim minion
master: 172.25.7.1
[root@server2 salt]# /etc/init.d/salt-minion start
[root@server1 ~]# salt-key  -L
# server2是被拒绝的

[root@server1 ~]# salt-key -A
# 接受所有端口

测试,执行salt命令:

[root@server1 ~]# salt server2 test.ping
server2:
    True
[root@server1 ~]# salt server2 cmd.run  hostname
server2:
    server2
[root@server1 ~]# salt server2 cmd.run  'df -h'
server2:
    Filesystem                    Size  Used Avail Use% Mounted on
    /dev/mapper/VolGroup-lv_root   19G  967M   17G   6% /
    tmpfs                         499M   16K  499M   1% /dev/shm
    /dev/vda1                     485M   33M  427M   8% /boot

二、对httpd进行安装和配置

在此之前我们先了解以下,yaml语言
YAML官方中文文档

默认的SLS文件的renderer是YAMLrenderer。YAML是一个有很多强大特性的标记性语言。Salt使用了一个YAML的小型子集，映射非常常用的数据结构，像列表和字典。YAMLrenderer的工作是将YAML数据格式的结构编译成为Python数据结构给Salt使用。

[root@server1 salt]# vim  master
# 设置base目录

[root@server1 salt]# /etc/init.d/salt-master restart
[root@server1~]# mkdir  /srv/salt
[root@server1 salt]# cd  /srv/salt/
[root@server1 salt]# mkdir  httpd

[root@server1 httpd]# vim  install.sls
apache-install:
  pkg.installed:
    - pkgs:
      - httpd
      - php
[root@server1 httpd]# salt server2 state.sls httpd.install
# 进行推送

在server2查看,安装成功

[root@server2 salt]# rpm -q  httpd
httpd-2.2.15-29.el6_4.x86_64
[root@server2 salt]# rpm -q  php
php-5.3.3-26.el6.x86_64

再度完善.sls文件

[root@server1 httpd]# vim  install.sls 
apache-install:
  pkg.installed:
    - pkgs:
      - httpd
      - php

  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://httpd/files/httpd.conf
    - mode: 644
    - user: root

  service.running:
    - name: httpd
    - enable: True
    - reload: True
    - watch:
      - file: apache-install

[root@server1 httpd]# mkdir files
[root@server2salt]#scp      /etc/httpd/conf/httpd.conf  server1:/srv/salt/httpd/files
# 修改server1的httpd.conf
Listen 8080

对两边的文件进行比对

[root@server2 salt]# md5sum /etc/httpd/conf/httpd.conf 
27a5c8d9e75351b08b8ca1171e8a0bbd  /etc/httpd/conf/httpd.conf
[root@server1 files]# md5sum httpd.conf 
b7ca7a0e786418ba7b5ad84efac70265  httpd.conf
# 结果不同,才会去更改server2的端口

[root@server1 files]# salt server2 state.sls httpd.install
# 进行推送

在server2查看

支持多种写法：

[root@server1 httpd]# vim  install.sls
httpd:
  pkg.installed:

php:
  pkg.installed:

apache:
  service.running:
    - name: httpd
    - enable: True
    - reload: True
    - watch:
      - file: /etc/httpd/conf/httpd.conf

/etc/httpd/conf/httpd.conf
  file.managed:
    - source: salt://httpd/files/httpd.conf
    - mode: 644
    - user: root

[root@server1 httpd]# vim  install.sls
apache-install:
  pkg.installed:
    - pkgs:
      - httpd
      - php


  service.running:
    - name: httpd
    - enable: True
    - reload: True
    - watch:
      - file: /etc/httpd/conf/httpd.conf

/etc/httpd/conf/httpd.conf:
  file.managed:
    - source: salt://httpd/files/httpd.conf
    - mode: 644
    - user: root
