saltstack实现haproxy+nginx+httpd实现高可用加负载均衡

---

server1和server4组成高可用和负载均衡集群,server2和server3作为后端真实服务器提供httpd和nginx服务
1、关于haproxy+nginx+httpd在上个博客已有介绍，这个实验是在上个实验完成的基础上进行的。
2、添加server4和server1的连接，互相认证。

3、keepalived部分

[root@server1 keepalived]# cat install.sls 
kp-install:
  pkg.installed:
    - pkgs:
      - openssl-devel
      - gcc
      - mailx                             #所部必须的依赖安装
  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               #编译安装

/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、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、高级推送
[root@server1 keepalived]# salt '*' state.highstate

显示推送成功！
5、测试

实验成功，负载均衡和高可用都已经实现！
