自动化运维工具Saltstack扩展（salt-ssh/salt-api/salt-syndic）

salt-syndic

将server4从salt-minion中分离出来，单独做一个Topmaster

[root@server1 ~]# salt-key -L
[root@server1 ~]# salt-key -d server4

[root@server4 ~]# /etc/init.d/salt-minion stop
[root@server4 ~]# chkconfig salt-minion off
[root@server4 ~]# /etc/init.d/haproxy stop
[root@server4 ~]# /etc/init.d/keepalived stop
[root@server4 ~]# yum install -y salt-master

[root@server4 ~]# cd /etc/salt/
[root@server4 salt]# vim master
 857 order_masters: True
[root@server4 salt]# /etc/init.d/salt-master start
[root@server4 salt]# salt-key -L  

[root@server1 ~]# yum install -y salt-syndic
[root@server1 ~]# cd /etc/salt/
[root@server1 salt]# vim master
 861 syndic_master: 172.25.40.4
[root@server1 salt]# /etc/init.d/salt-master restart
[root@server1 salt]# /etc/init.d/salt-syndic start

【server4】将server1的钥匙传给server4

[root@server4 salt]# salt-key -L
[root@server4 salt]# salt-key -A server1

测试：

[root@server4 salt]# salt '*' test.ping
[root@server4 salt]# salt-key -L

salt-ssh

[root@server3 ~]# /etc/init.d/salt-minion stop

[root@server1 salt]# yum install -y salt-ssh
[root@server1 salt]# vim /etc/salt/roster 
server3:
  host: 172.25.40.3
  user: root
  passwd: westos
[root@server1 salt]# vim master   #注释所有关于mysql

测试：

[root@server1 salt]# salt-ssh 'server3' test.ping
[root@server1 salt]# salt-ssh 'server3' test.ping -i

[root@server1 salt]# salt-ssh 'server3' my_disk.df

---

salt-api

[root@server3 ~]# /etc/init.d/salt-minion start

[root@server1 salt]# yum install -y salt-api
[root@server1 salt]# cd /etc/pki/
[root@server1 pki]# cd tls/
[root@server1 tls]# cd private/
[root@server1 private]# openssl genrsa 1024 > localhost.key

[root@server1 private]# cd ..
[root@server1 tls]# cd certs/
[root@server1 certs]# make testcert

[root@server1 certs]# cd /etc/salt/
[root@server1 salt]# cd master.d/
[root@server1 master.d]# vim api.conf
rest_cherrypy:
  port: 8000
  ssl_crt: /etc/pki/tls/certs/localhost.crt
  ssl_key: /etc/pki/tls/private/localhost.key
[root@server1 master.d]# vim auth.conf
external_auth:
  pam:
    saltapi:
      - '.*'
      - '@wheel'
      - '@runner'
      - '@jobs'
[root@server1 master.d]# useradd saltapi    #建立用户
[root@server1 master.d]# passwd saltapi     #设置密码
[root@server1 master.d]# /etc/init.d/salt-master stop
[root@server1 master.d]# /etc/init.d/salt-master start
[root@server1 master.d]# /etc/init.d/salt-api start
[root@server1 master.d]# netstat -antlp |grep :8000

获取Token

[root@server1 master.d]# curl -sSk https://localhost:8000/login \

> -d username=saltapi \

> -d eauth=pam

测试：

将【server3】上的nginx关闭

[root@server3 ~]# /etc/init.d/nginx stop

执行python脚本

[root@server1 ~]# python salt-api.py

[root@server3 ~]# ps ax   #此时nginx已经开启
