server1和server4組成高可用和負載均衡集群,server2和server3作為后端真實服務器提供httpd和nginx服務
1姑蓝、關于haproxy+nginx+httpd在上個博客已有介紹晓猛，這個實驗是在上個實驗完成的基礎上進行的。
2、添加server4和server1的連接线椰，互相認證进倍。

[root@server1 keepalived]# cat install.sls 
kp-install:
  pkg.installed:
    - pkgs:
      - openssl-devel
      - gcc
      - mailx                             #所部必須的依賴安裝
  file.managed:
    - name: /mnt/keepalived-2.0.6.tar.gz
    - source: salt://keepalived/files/keepalived-2.0.6.tar.gz
  cmd.run:
    - name: cd /mnt && tar zxf keepalived-2.0.6.tar.gz && cd keepalived-2.0.6 && ./configure --prefix=/usr/local/keepalived --with-init=SYSV &> /dev/null && make &> /dev/null && make install &> /dev/null
    - creates: /usr/local/keepalived               #編譯安裝

/etc/keepalived:
  file.directory:
    - mode: 755

/etc/sysconfig/keepalived:
  file.symlink:
    - target: /usr/local/keepalived/sbin/keepalived  

/sbin/keepalived:
  file.symlink:
    - target: /usr/local/keepalived/sbin/keepalived


[root@server1 keepalived]# cat service.sls 
include:
  - keepalived.install

/etc/keepalived/keepalived.conf:
  file.managed:
    - source: salt://keepalived/files/keepalived.conf
    - template: jinja
    - context:
      STATE: {{ pillar['state'] }}
      vrid: {{ pillar['vrid'] }}
      priority: {{ pillar['priority'] }}

kp-service:
  file.managed:
    - name: /etc/init.d/keepalived
    - source: salt://keepalived/files/keepalived
    - mode: 755
  service.running:
    - name: keepalived
    - reload: True
    - watch:
      - file: /etc/keepalived/keepalived.conf

4执俩、jinjia部分

[root@server1 pillar]# cd keepalived/
[root@server1 keepalived]# cat install.sls 
{% if grains['fqdn'] == 'server1' %}
state: MASTER
vrid: 24
priority: 100
{% elif grains['fqdn'] == 'server4' %}
state: BACKUP
vrid: 24
priority: 50
{% endif %}

[root@server1 web]# pwd
/srv/pillar/web
[root@server1 web]# cat install.sls 
{% if grains['fqdn'] == 'server2' %}
webserver: apache
port: 80
bind: 172.25.4.2
{% elif grains['fqdn'] == 'server3' %}
webserver: nginx
port: 80
bind: 172.25.4.3
{% endif %}

[root@server1 pillar]# pwd
/srv/pillar
[root@server1 pillar]# cat 
keepalived/ top.sls     web/        
[root@server1 pillar]# cat top.sls 
base:
  'server2':
    - web.install
  'server3':
    - web.install
  'server1':
    - keepalived.install
  'server4':
    - keepalived.install

5、高級推送
[root@server1 keepalived]# salt '*' state.highstate

顯示推送成功癌刽！
