saltstack之api的使用

api的使用
1.安装salt-api
[root@server1 ~]# yum install -y salt-api##安装api
2.生成证书和秘钥
[root@server1 ~]# cd /etc/pki/tls/private/##生成证书和私钥
[root@server1 private]# openssl genrsa 2048 > localhost.key

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

3.编辑api的配置文件并添加证书和秘钥

[root@server1 certs]# cd /etc/salt
[root@server1 salt]# vim master
[root@server1 salt]# pwd
/etc/salt
[root@server1 salt]# cd master.d
[root@server1 master.d]# vim api.conf
[root@server1 master.d]# cat api.conf ##api.conf文件
rest_cherrypy:
  port: 8000##端口
  ssl_crt: /etc/pki/tls/certs/localhost.crt ##证书
  ssl_key: /etc/pki/tls/private/localhost.key##秘钥

4.编辑授权文件

[root@server1 master.d]# vim auth.conf
[root@server1 master.d]# cat auth.conf 
external_auth:
  pam:
    saltapi:##授权用户（以下四行都为权限）
      - .*
      - '@wheel'
      - '@runner'
      - '@jobs'

5.建立授权用户并修改密码
[root@server1 master.d]# useradd saltapi
[root@server1 master.d]# passwd saltapi

6.重启salt-master服务并开启api服务
[root@server1 master.d]# systemctl restart salt-master
[root@server1 master.d]# systemctl start salt-api

7.查看监听端口（8000）是否开启

8.获取api值（使用自己授权的用户进行登陆即可获取api值）
[root@server1 master.d]# curl -sSk https://172.25.32.1:8000/login -H ‘Accept: application/x-yaml’ -d username=saltapi -d password=redhat -d eauth=pam##获取api

上图中‘token’对应一栏为api值
9.以api值使用ping命令卡能否成功
[root@server1 master.d]# curl -sSk https://172.25.42.1:8000 -H ‘Accept: application/x-yaml’ -H ‘X-Auth-Token: b182ffb020daa4110dbcc0815cb678e265a34fa4’ -d client=local -d tgt=’*’ -d fun=test.ping##使用api执行ping命令

可以成功表示连接正确建立

• server1上编辑脚本进行测试

[root@server1 ~]# vim saltapi.sh 
[root@server1 ~]# cat saltapi.sh

修改以下部分即可

def main():
    sapi = SaltAPI(url="https://172.25.32.1:8000",username="saltapi",password="redhat")
    #sapi.token_id()
    print sapi.list_all_key()  ##打开该端口查看所有key
    #sapi.delete_key('test-01')
    #sapi.accept_key('test-01')
    sapi.deploy('server3','nginx.service')  ##在server3推送nginx
    #print sapi.remote_noarg_execution('test-01','grains.items')

执行后查看结果：
打印出的key值

检测server3是否推送nginx服务
