=========>服務管理子產品

[root@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' %}

    - STATEID: BACKUP

    - PRIORITYID: 100

    {% endif %}

  service.running:

    - name: keepalived

    - enable: True

    - watch:

      - file: keepalived-service

執行一般狀态：

[root@linux-node1 cluster]# salt '*' state.sls cluster.haproxy-outside-keepalived env=prod

linux-node2.example.com:

.............

Summary

-------------

Succeeded: 15 (changed=2)

Failed:     0

Total states run:     15

linux-node1.example.com:

............

===============top file檔案，供執行進階狀态用

[root@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':

執行進階狀态：

[root@linux-node1 cluster]# salt '*' state.highstate

................

Succeeded: 29

Total states run:     29

然後通過指令檢視虛拟IP狀态：

[root@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                               ===============>此處為虛拟IP

    inet6 fe80::20c:29ff:fe5c:e013/64 scope link 

       valid_lft forever preferred_lft forever

[root@linux-node2 ~]# ip ad li

    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 

停掉linux-node1上面的keepalived服務然後再檢視狀态：

[root@linux-node1 cluster]# /etc/init.d/keepalived stop

停止 keepalived：                                          [确定]

然後再次通過指令檢視虛拟IP狀态：

    inet 10.0.0.11/32 scope global eth0                             ==================>虛拟IP已漂移到linux-node2上面

       valid_lft forever preferred_lft forever
