The use of api
1. Install salt-api
[root@server1 ~]# Yum install-y salt-api # install API
2. Generating certificates and secret keys
[root@server1~] # cd/etc/pki/tls/private/# generates certificates and private keys
[root@server1 private]# openssl genrsa 2048 > localhost.key
[root@server1 private]# cd ...
[root@server1 tls]# cd certs
[root@server1 certs]# make testcert
3. Edit the api configuration file and add certificates and keys
[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 file rest_cherrypy: port: 8000##port ssl_crt: /etc/pki/tls/certs/localhost.crt ##certificate ssl_key: /etc/pki/tls/private/localhost.key##Secret key
4. Editing Authorization Documents
[root@server1 master.d]# vim auth.conf
[root@server1 master.d]# cat auth.conf
external_auth:
pam:
saltapi:##Authorized users (all four lines below are privileges)
- .*
- '@wheel'
- '@runner'
- '@jobs'
5. Establish authorized users and modify passwords
[root@server1 master.d]# useradd saltapi
[root@server1 master.d]# passwd saltapi
6. Restart the salt-master service and open the api service
[root@server1 master.d]# systemctl restart salt-master
[root@server1 master.d]# systemctl start salt-api
7. Check if the listening port (8000) is open
8. Get the api value (you can get the api value by logging in with your authorized user)
[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_ # Get api
In the figure above,'token'corresponds to a column with api values
9. Success of using ping command card with api value
[root@server1 master.d]# curl -sSk https://172.25.42.1:8000 - H'Accept: application/x-yaml'-H'X-Auth-Token: b182ffb020daa4110 dbcc0815cb678e265a34fa4'-d client=local-d tgt='*'-d fun=test.ping\\\\\\\\
Successfully indicate that the connection is established correctly
- Editing scripts on server 1 for testing
[root@server1 ~]# vim saltapi.sh
[root@server1 ~]# cat saltapi.sh
