我们前面讲过了saltstack的c/s，ssh等推送方式，其实我们还可以使用api推送的方式来馆及节点，下面我们就来部署一下api接口的saltstack推送
1.之前因为使用ssh关掉了minion，我们重新先开启
[root@server2 minion]# systemctl start salt-minion
[root@server3 minion]# systemctl start salt-minion
2.配置签名证书
由于现在大多数的api接口使用https的方式，那么我们就来创建证书
[root@server1 salt]# cd /etc/pki/tls/private/
[root@server1 private]# openssl genrsa 1024 我们使用rsa加密，加密位数为1024
Generating RSA private key, 1024 bit long modulus

-----END RSA PRIVATE KEY-----
[root@server1 private]# openssl genrsa 1024 > localhost.key
[root@server1 private]# ls
localhost.key
[root@server1 private]# cd ..
[root@server1 tls]# cd certs/
[root@server1 certs]# ls
ca-bundle.crt ca-bundle.trust.crt make-dummy-cert Makefile renew-dummy-cert
[root@server1 certs]# make testcert 因为这里有makefile的脚本文件，所以我们直接使用它来创建证书
3.编辑api.conf和auth.conf配置文件
[root@server1 certs]# cd /etc/salt/master.d/
[root@server1 master.d]# ls
[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'
- '@runner'
- '@jobs'
4.创建一个saltapi用户（一会儿测试使用）
[root@server1 master.d]# useradd saltapi
[root@server1 master.d]# passwd saltapi
5.打开salt-api，重起master，查看8000端口是否开启
[root@server1 master.d]# systemctl restart salt-api
[root@server1 master.d]# systemctl restart salt-master
[root@server1 master.d]# netstat -antlp | grep 8000
tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 14614/salt-api
tcp 0 0 127.0.0.1:51028 127.0.0.1:8000 TIME_WAIT -
6.在物理机进行测试
1.验证服务并获取token
[root@foundation66 ~]# curl -sSk https://172.25.66.1:8000/login -H 'Accept: application/x-yaml' -d username=saltapi -d password=redhat -d eauth=pam
return:
- eauth: pam
expire: 1561022083.921096
perms:
- .*
- '@wheel'
- '@runner'
- '@jobs'
start: 1560978883.921095
token: 74dd0818ddf78811b3840444d8b04785dc121e82
user: saltapi
2.利用token号进行测试
[root@foundation66 ~]# curl -sSk https://172.25.66.1:8000 -H 'Accept: application/x-yaml' -H 'X-Auth- Token: 74dd0818ddf78811b3840444d8b04785dc121e82' -d client=local -d tgt='*' -d fun=test.ping
return:
- server2: true
server3: true
3.配置python脚本测试能否成功
[root@foundation66 ~]# vim saltapi.py

jid = content['return'][0]['jid']
return jid
def main():
sapi = SaltAPI(url='https://172.25.66.1:8000',username='saltapi',password='redhat') 设置api接口，用户及用户密码
#sapi.token_id()
print sapi.list_all_key() 列出所有节点
#sapi.delete_key('test-01')
#sapi.accept_key('test-01')
#sapi.deploy('*','httpd.apache')
#print sapi.remote_noarg_execution('test-01','grains.items')
if __name__ == '__main__':
main()
这里的各种python脚本利用api接口的文件再github上有很多，可以自己下载一个，或者直接用我的这个进行测试也可以
[root@foundation66 ~]# python saltapi.py
([u'server2', u'server3'], [])
成功列出节点
修改python文件的主方法继续进行测试
def main():
sapi = SaltAPI(url='https://172.25.66.1:8000',username='saltapi',password='redhat')
#sapi.token_id()
#print sapi.list_all_key()
#sapi.delete_key('test-01')
#sapi.accept_key('test-01')
sapi.deploy('server3','nginx.service') 注意这里使用的deploy我们使用的是我们之前写的部署nginx的sls文件，我们再server3上部署nginx
#print sapi.remote_noarg_execution('test-01','grains.items')
为了消除实验影响，我们关闭server3上的nginx（无论其是否开启）
[root@server3 salt]# systemctl stop nginx
[root@server3 salt]# curl server3
curl: (7) Failed connect to server3:80; Connection refused
测试
