saltstack自动化部署keepalived

一、saltstack的安装部署
主机环境：

server1： 172.25.60.1 master
server2： 172.25.60.2 minion

1、 server1安装软件

 [root@server1 2018]# ls
libsodium-1.0.16-1.el7.x86_64.rpm
openpgm-5.2.122-2.el7.x86_64.rpm
python2-libcloud-2.0.0-2.el7.noarch.rpm
python-cherrypy-5.6.0-2.el7.noarch.rpm
python-crypto-2.6.1-2.el7.x86_64.rpm
python-futures-3.0.3-1.el7.noarch.rpm
python-msgpack-0.4.6-1.el7.x86_64.rpm
python-psutil-2.2.1-1.el7.x86_64.rpm
python-tornado-4.2.1-1.el7.x86_64.rpm
python-zmq-15.3.0-3.el7.x86_64.rpm
PyYAML-3.11-1.el7.x86_64.rpm
repodata
salt-2018.3.3-1.el7.noarch.rpm
salt-api-2018.3.3-1.el7.noarch.rpm
salt-cloud-2018.3.3-1.el7.noarch.rpm
salt-master-2018.3.3-1.el7.noarch.rpm
salt-minion-2018.3.3-1.el7.noarch.rpm
salt-ssh-2018.3.3-1.el7.noarch.rpm
salt-syndic-2018.3.3-1.el7.noarch.rpm
zeromq-4.1.4-7.el7.x86_64.rpm
[root@server1 2018]# yum install -y *

2、server1上编辑配置文件，并开启master和minion

[root@server1 2018]# cd /etc/salt/
[root@server1 salt]# vim minion
写入：master: 172.25.60.1
[root@server1 salt]# systemctl start salt-master
[root@server1 salt]# systemctl start salt-minion
[root@server1 salt]# netstat -antlp
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp6       0      0 :::22                   :::*                    LISTEN      709/sshd            
tcp6       0      0 ::1:25                  :::*                    LISTEN      881/master          

##
4505端口：用来链接slave，发布订阅 
4506端口：请求响应，模式为：zmq（消息队列）

3、server2也安装上述软件包，编辑配置文件，并开启minion

[root@server2 2018]#  cd /etc/salt/
[root@server2 salt]# vim minion
master: 172.25.60.1
[root@server2 salt]# systemctl start salt-minion

4、在master添加minion（master和minion交换公钥的过程）

 [root@server1 salt]# salt-key -L     #查看 minion 列表（这时候 saltstack-minion是红色的）
[root@server1 salt]# salt-key -A     # 添加显示的所有主机 
[root@server1 salt]# salt-key -L

5、查看

[root@server1 salt]# yum install -y lsof
[root@server1 salt]# lsof -i :4505

6、测试

[root@server1 minions]# salt '*' test.ping
 [root@server1 minions]# salt '*' cmd.run hostname
 [root@server1 minions]# salt '*' cmd.run df

二、配置keepalived高可用
1、在server1建立/srv/salt目录，建立keepalived目录，进到目录里边编辑安装keepalived的sls推送文件

[root@server1 salt]# mkdir keepalived
[root@server1 salt]# cd keepalived/
[root@server1 keepalived]# mkdir files
[root@server1 keepalived]# vim install.sls
[root@server1 keepalived]# cat install.sls 
kp-install:
  pkg.installed:
    - pkgs:
      - keepalived
  file.managed:
    - name: /etc/keepalived/keepalived.conf
    - source: salt://keepalived/files/keepalived.conf
    - template: jinja
      {% if grains['fqdn'] == 'server1' %}        # server1是master
      STATE: MASTER
      VRID: 51
      PRIORITY: 100
      {% elif grains['fqdn'] == 'server2' %}      # server2是backup
      STATE: BACKUP
      VRID: 51
      PRIORITY: 50
      {% endif %}
   
  service.running:
    - name: keepalived
    - reload: True
    - watch:
      - file: kp-install

2、编辑 keepalived的脚本，配置文件远程发送到到sevrer1中/srv/salt/keepalived/files

[root@server2 keepalived]# scp keepalived.conf server1:/srv/salt/keepalived/files

[root@server1 files]# cat keepalived.conf 
! Configuration File for keepalived

global_defs {
   notification_email {
	root@localhost
   }
   notification_email_from keepalived@localhost
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id LVS_DEVEL
}

vrrp_instance VI_1 {
    state {{ STATE }}
    interface eth0
    virtual_router_id {{ VRID }}
    priority {{ PRIORITY }}
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        172.25.60.100
    }
}

在server1上执行

[root@server1 yum.repos.d]# salt server2 state.sls keepalived install
