SaltStack配置管理-业务引用keepalived

而微软

================>keepalived的配置文件
[iyunv@linux-node1 cluster]# cat /srv/salt/prod/cluster/files/haproxy-outside-keepalived.conf
! Configuration File for keepalived
global_defs {
   notification_email {
     saltstack@example.com
   }
   notification_email_from keepalived@example.com
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id {{ ROUTEID }}
}

vrrp_instance haproxy_ha {
state {{ STATEID }}
interface eth0
    virtual_router_id 36

    advert_int 1
authentication {
auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {

    }
}

=========>服务管理模块
[iyunv@linux-node1 cluster]# cat /srv/salt/prod/cluster/haproxy-outside-keepalives.sls
include:
  - keepalived.install

keepalived-service:
  file.managed:
    - name: /etc/keepalived/keepalived.conf
    - source: salt://cluster/files/haproxy-outside-keepalived.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
    {% if grains['fqdn'] == 'linux-node1.example.com' %}
    - ROUTEID: haproxy_ha
    - STATEID: MASTER
    - PRIORITYID: 150
    {% elif grains['fqdn'] == 'linux-node2.example.com' %}
    - ROUTEID: haproxy_ha
    - STATEID: BACKUP
    - PRIORITYID: 100
    {% endif %}
  service.running:
    - name: keepalived
    - enable: True
    - watch:
      - file: keepalived-service

执行一般状态：
[iyunv@linux-node1 cluster]# salt '*' state.sls cluster.haproxy-outside-keepalived env=prod
linux-node2.example.com:
.............
Summary
-------------
Succeeded: 15 (changed=2)

linux-node1.example.com:

===============top file文件，供执行高级状态用
[iyunv@linux-node1 cluster]# cat /srv/salt/base/top.sls
base:
  '*':
    - init.env_init

prod:
  'linux-node1.example.com':
    - cluster.haproxy-outside
    - cluster.haproxy-outside-keepalived
  'linux-node2.example.com':
    - cluster.haproxy-outside
    - cluster.haproxy-outside-keepalived

执行高级状态：
[iyunv@linux-node1 cluster]# salt '*' state.highstate
linux-node2.example.com:
................
Summary

Succeeded: 29

Total states run:     29
linux-node1.example.com:

然后通过命令查看虚拟IP状态：
[iyunv@linux-node1 cluster]# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:5c:e0:13 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.7/24 brd 10.0.0.255 scope global eth0
    inet 10.0.0.11/32 scope global eth0                               ===============>此处为虚拟IP
    inet6 fe80::20c:29ff:fe5c:e013/64 scope link
       valid_lft forever preferred_lft forever

[iyunv@linux-node2 ~]# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:38:4b:e3 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.8/24 brd 10.0.0.255 scope global eth0
    inet6 fe80::20c:29ff:fe38:4be3/64 scope link
       valid_lft forever preferred_lft forever

停掉linux-node1上面的keepalived服务然后再查看状态：
[iyunv@linux-node1 cluster]# /etc/init.d/keepalived stop
停止 keepalived：                                          [确定]
然后再次通过命令查看虚拟IP状态：
[iyunv@linux-node1 cluster]# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:5c:e0:13 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.7/24 brd 10.0.0.255 scope global eth0
    inet6 fe80::20c:29ff:fe5c:e013/64 scope link
       valid_lft forever preferred_lft forever

[iyunv@linux-node2 ~]# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:38:4b:e3 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.8/24 brd 10.0.0.255 scope global eth0
    inet 10.0.0.11/32 scope global eth0                             ==================>虚拟IP已漂移到linux-node2上面
    inet6 fe80::20c:29ff:fe38:4be3/64 scope link
       valid_lft forever preferred_lft forever
