saltstack -API调用，Syndic配置

salt-api调用

• 1、生成私钥

cd /etc/pki/tls/
[root@server1 private]# openssl genrsa 2048 > localhost.key

• 2、认证证书

cd /etc/pki/tls/certs
[root@server1 certs]# make testcert

• 3、配置salt-api

cd /etc/salt/master.d/
[root@server1 master.d]# vim api.conf
[root@server1 master.d]# cat 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
[root@server1 master.d]# cat auth.conf 
external_auth:
  pam:
    saltapi:
      -  .*
      - '@wheel'   # to allow access to all wheel modules
      - '@runner'  # to allow access to all runner modules
      - '@jobs'    # to 

• 4、添加用户

useradd saltapi
passwd westos

• 5、生成token

 curl -sSk https://localhost:8000/login -H 'Accept: application/x-yaml'  -d username=saltapi  -d password=westos -d eauth=pam

• 6、获取token

[root@server1 certs]# curl -sSk https://localhost:8000 -H 'Accept: application/x-yaml' -H 'X-Auth-Token: 1418c69a5515fd25c5423944e66eacafcfdfb835' -d client=local -d tgt='*' -d fun=test.ping

• 7、编写python脚本调用api

server2已经部署完成httpd

Syndic配置

• 1、topmaster去激活master

# vim /etc/salt/master
order_masters: True  #当需要syndic时激活master

• 2、master：配置syndic

# vim /etc/salt/master
syndic_master: 172.25.14.4

• 3、topmaster
  
• 4、测试，topmaster发送指令，通过syndic去告知master，master再去管理所连接的minion
