一.salt-syndic

syndic就是一層代理，如同zabbix proxy功能一樣，隔離master與minion，使其不需要通訊，只需要與syndic都通訊就可以

1.server4安裝salt-master

[root@server4 ~]# scp server1:/etc/yum.repos.d/saltstack.repo /etc/yum.repos.d/ [root@server4 ~]# yum clean all [root@server4 ~]# yum repolist [root@server4 ~]# yum install salt-master -y

2.server4安裝salt-syndic

[root@server4 ~]# yum install salt-syndic-2019.2.0-1.el7.noarch.rpm -y [root@server4 ~]# systemctl start salt-syndic

3.修改/etc/salt/master配置文件

[root@server4 ~]# vim /etc/salt/master [root@server4 ~]# systemctl start salt-master [root@server4 ~]# netstat -antlp

4.server1安裝salt-syndic，并打開服務

[root@server1 ~]# yum install salt-syndic-2019.2.0-1.el7.noarch.rpm -y [root@server1 ~]# systemctl start salt-syndic

編輯server1的salt-master配置文件

[root@server1 ~]# vim /etc/salt/master [root@server1 ~]# systemctl restart salt-master.service

5.server1與server4建立聯系

[root@server4 ~]# salt-key -L Rejected Keys: [root@server4 ~]# salt-key -A [root@server4 ~]# salt-key -L

測試：

[root@server4 ~]# salt '*' test.ping

二.salt-ssh

salt-ssh：是通過ssh協議執行命令進行管理服務器,不需要在服務器端安裝minion客戶端,如時有安裝minion也可以調用minion模塊;salt-ssh有點類似ansible 無客戶端基于ssh協議進行管理服務器.通過roser(/etc/salt/roser)配置文件.

1.關閉server2的salt-minion便于驗證

[root@server2 ~]# systemctl stop salt-minion.service

2.server1安裝salt-ssh模塊并修改文件/etc/salt/roster

[root@server1 ~]# yum install salt-ssh -y [root@server1 ~]# vim /etc/salt/roster

3.測試

[root@server1 ~]# salt-ssh '*' test.ping [root@server1 ~]# salt-ssh server2 -r "df" [root@server1 ~]# salt-ssh server2 -r "hostname"

三.salt-api

1.在server1（master）上安裝salt-api

[root@server1 ~]# yum install -y salt-api

2.在/etc/pki/tls/private目錄下生成相應的鑰匙

[root@server1 ~]# cd /etc/pki [root@server1 pki]# ls CA consumer java product rpm-gpg tls ca-trust entitlement nssdb product-default rsyslog [root@server1 pki]# cd tls/ [root@server1 tls]# ls cert.pem certs misc openssl.cnf private [root@server1 tls]# cd private/ [root@server1 private]# ls [root@server1 private]# openssl genrsa 2048 > localhost.key

3.在/etc/pki/tls/certs目錄下面生成相應的證書，因為在這個目錄下面有makefile文件，該文件里面有生成證書的相應方式，使用鑰匙生成證書

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

4.server1的/etc/salt/master文件中有api模塊命名方式

[root@server1 certs]# cd /etc/salt [root@server1 salt]# vim master

5.在/etc/salt/master.d目錄下編輯api的配置文件添加證書及其鑰匙

[root@server1 salt]# 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: 8000ssl_crt: /etc/pki/tls/certs/localhost.crtssl_key: /etc/pki/tls/private/localhost.key

6.編輯授權文件

[root@server1 master.d]# pwd /etc/salt/master.d [root@server1 master.d]# vim auth.conf [root@server1 master.d]# cat auth.conf external_auth:pam:saltapi:- .*- '@wheel'- '@runner' - '@jobs'

7.建立授權用戶及其設置密碼

[root@server1 master.d]# useradd saltapi [root@server1 master.d]# passwd saltapi [root@server1 master.d]# systemctl restart salt-master [root@server1 master.d]# systemctl start salt-api [root@server1 master.d]# netstat -antlp ##端口8000

8.測試

[root@server1 master.d]# curl -sSk https://172.25.31.1:8000/login -H 'ACCEPT: application/x-yaml' -d username=saltapi -d password=westos -d eauth=pamreturn: [root@server1 master.d]# curl -sSk https://172.25.31.1:8000 -H 'ACCEPT: application/x-yaml' -H 'X-Auth-Token: 0cbada767c80e60b9d204df23206efa0dffb349a' -d client=local -d tgt='*' -d fun=test.ping
