功能模块-----keepalived模块


写之前先找一台主机源码安装测试
http://www.keepalived.org/software/keepalived-1.2.19.tar.gz
[iyunv@node1 tools]# tar xf keepalived-1.2.19.tar.gz
[iyunv@node1 tools]# cd keepalived-1.2.19
[iyunv@node1 keepalived-1.2.19]# ./configure --prefix=/usr/local/keepalived --disable-fwmark
[iyunv@node1 keepalived-1.2.19]# make && make install
keepalived-1.2.19/keepalived/etc/init.d/keepalived.init       #启动脚本
keepalived-1.2.19/keepalived/etc/keepalived/keepalived.conf    #配置文件

配置keepalived模块路径及相关文件
[iyunv@node1 ~]# mkdir /srv/salt/prod/keepalived
[iyunv@node1 ~]# mkdir /srv/salt/prod/keepalived/files
[iyunv@node1 keepalived]# cp ~/tools/keepalived-1.2.19.tar.gz /srv/salt/prod/keepalived/
files/
[iyunv@node1 tools]#cp keepalived-1.2.19/keepalived/etc/init.d/keepalived.init /srv/salt/prod/keepalived/files/        #复制启动脚本
[iyunv@node1 tools]#cp keepalived-1.2.19/keepalived/etc/keepalived/keepalived.conf /srv/salt/prod/keepalived/files/           #复制配置文件
[iyunv@node1 tools]# cp keepalived-1.2.19/keepalived/etc/init.d/keepalived.sysconfig /srv/salt/prod/keepalived/files/
[iyunv@node1 tools]# cd /srv/salt/prod/keepalived/files/
[iyunv@node1 files]# vim keepalived.init     #修改启动脚本路径
daemon /usr/local/keepalived/sbin/keepalived ${KEEPALIVED_OPTIONS}

1.keepalived功能模块
[iyunv@node1 keepalived]# cd /srv/salt/prod/keepalived/
[iyunv@node1 keepalived]# cat install.sls
include:
  - pkg.pkg-init
keepalived-install:

    - source: salt://keepalived/files/keepalived-1.2.19.tar.gz
    - user: root
    - group: root
    - mode: 755
  cmd.run:
    - name: cd /usr/local/src/ && tar xf keepalived-1.2.19.tar.gz && cd keepalived-1.2.19 && ./configure --prefix=/usr/local/keepalived --disable-fwmark && make &&make install
    - unless: test -d /usr/local/keepalived
    - require:
      - pkg: pkg-init
      - file: keepalived-install

  file.managed:
    - name: /etc/init.d/keepalived
    - source: salt://keepalived/files/keepalived.init
    - user: root
    - group: root
    - mode: 755
  cmd.run:
    - name: chkconfig --add keepalived
    - unless: chkconfig --list |grep keepalived

[iyunv@node1 files]# salt '*' state.sls keepalived.install env=prod     #手动测试一下

2.keepalived业务模块
[iyunv@node1 ~]# cd /srv/salt/prod/cluster/files/
[iyunv@node1 files]# cat haproxy-outside-keepalived.cfg #keepalived配置文件,里面用到了jinja变量
#configutation file for keepalive
globlal_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 eth2
    virtual_router_id 36
priority {{PRIORITYID}}
    advert_int 1
authentication {
auth_type PASS
    auth_pass 1111
  }
  virtual_ipaddress {
    192.168.10.130
  }
}

[iyunv@node1 ~]# cd /srv/salt/prod/cluster/
[iyunv@node1 cluster]# cat haproxy-outside-keepalived.sls
include:
- keepalived.install

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


[iyunv@node1 cluster]# salt '*' state.sls cluster.haproxy-outside-keepalived env=prod  #测试一下

指定服务器执行keepalived模块
[iyunv@node1 salt]# cat /srv/salt/base/top.sls
base:
  '*':
    - init.env_init
prod:
  'node1':
    - cluster.haproxy-outside
    - cluster.haproxy-outside-keepalived
  'node2':
    - cluster.haproxy-outside
    - cluster.haproxy-outside-keepalived


[iyunv@node1 salt]# salt '*' state.highstate    #到这步执行成功的话就实现了keepalived+haproxy

遇到问题：发现keepalived 虚拟vip写不上去
查看日志 cat /var/log/messages，发现下面一句
Aug 11 15:10:12 node1 Keepalived_vrrp[29442]: VRRP_Instance(haproxy_ha{) sending 0 priority
haproxy_ha后面打了个空格解决
vrrp_instance haproxy_ha {
