## 一.salt-syndic ##

syndic就是一层代理，如同zabbix proxy功能一样，隔离master与minion，使其不需要通讯，只需要与syndic都通讯就可以

1.server4安装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安装salt-syndic

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

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 1]  
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安装salt-syndic，并打开服务

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

编辑server1的salt-master配置文件

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

![在这里插入图片描述][20190814101206902.png]

5.server1与server4建立联系

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

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 3]

测试：

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

![在这里插入图片描述][20190814101543791.png]

## 二.salt-ssh ##

salt-ssh：是通过ssh协议执行命令进行管理服务器,不需要在服务器端安装minion客户端,如时有安装minion也可以调用minion模块;salt-ssh有点类似ansible 无客户端基于ssh协议进行管理服务器.通过roser(/etc/salt/roser)配置文件.

1.关闭server2的salt-minion便于验证

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

2.server1安装salt-ssh模块并修改文件/etc/salt/roster

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

![在这里插入图片描述][20190814102724975.png]

3.测试

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

![在这里插入图片描述][20190814103022271.png]

## 三.salt-api ##

1.在server1（master）上安装salt-api

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

![在这里插入图片描述][20190814103413282.png]  
2.在/etc/pki/tls/private目录下生成相应的钥匙

[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目录下面生成相应的证书，因为在这个目录下面有makefile文件，该文件里面有生成证书的相应方式，使用钥匙生成证书

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

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 6]  
4.server1的/etc/salt/master文件中有api模块命名方式

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

![在这里插入图片描述][20190814103952459.png]

5.在/etc/salt/master.d目录下编辑api的配置文件添加证书及其钥匙

[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: 8000
      ssl_crt: /etc/pki/tls/certs/localhost.crt
      ssl_key: /etc/pki/tls/private/localhost.key

![在这里插入图片描述][2019081410414495.png]  
6.编辑授权文件

[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.建立授权用户及其设置密码

[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.测试

[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
