一.salt-自定义模块
1.在master端（server1）创建目录：
[root@server1 ~]# mkdir /srv/salt/_modules
2.在该目录下编辑disk的python模块
cd /srv/salt/_modules/
[root@server1 _modules]# vim my_disk.py
#! /usr/bin/env python
def df():
return __salt__['cmd.run']('df -h')
3.给server2推送测试：salt server2 saltutil.sync_modules
4. 在server2上，查看 /var/cache/salt/minion/目录结构
5.测试：salt server2 my_disk.df
二.salt-syndic
中心master可以理解为公司大boss，syndic节点相当于公司经理，minion相当于是小员工。中心master将任务通过sysndic节点分发给minion端。
实验环境：
| 主机名 | 功能 |
|---|---|
| server1 | Syndic节点 |
| server2 | minion |
| server3 | minion |
| server4 | top master |
1.在server1上安装syndic： yum install -y salt-syndic
2.修改配置文件：
vim /etc/salt/master
file_roots:
base:
- /srv/salt
syndic_master: 172.25.13.4
3.设置完后重启master: systemctl restart salt-master.service
4.在server4（top-master）端安装master：
yum install -y salt-master
5.在server4上编辑配置文件：
vim /etc/salt/master
file_roots:
base:
- /srv/salt
order_masters: true
6.在server4上开启master：systemctl start salt-master.service
7. 在server1上开启syndic： systemctl start salt-syndic
8. 在server4（top master）与server1交换密钥
9. 测试：salt ‘*’ test.ping
三.salt-ssh模块
1.在server1上安装ssh：yum install -y salt-ssh
2.在server2和server3上将minion停止：systemctl stop salt-minion
3.在salt目录下： cd /etc/salt/编辑文件：
vim roster
server2:
host: 172.25.13.2
user: root
passwd: westos
server3:
host: 172.25.13.3
user: root
passwd: westos
4.测试：
四.API
1.在master端安装api：yum install -y salt-api
2. 进入到认证证书的目录：/etc/pki/tls/certs
在该目录下有一个Makefile文件，可以查看规则
3. 进入到/etc/pki/tls/private/下
4. 生成key：openssl genrsa 1024
指定key的名字：openssl genrsa 1024 > localhost.key
查看是否生成：ll localhost.key
5. 进入到/etc/pki/tls/certs下进行认证
7.在/etc/salt/master.d/下创建文件api.conf
[root@server1 certs]# cd /etc/salt/master.d/
[root@server1 master.d]# vim api.conf
rest_cherrypy:
port: 8000
ssl_crt: /etc/pki/tls/certs/localhost.crt
ssl_key: /etc/pki/tls/private/localhost.key
8.编辑vim auth.conf
[root@server1 master.d]# vim auth.conf
external_auth:
pam:
saltapi:
- .*
- '@wheel'
- '@runner'
- '@jobs'
9.创建用户，并设置密码
10.重启master并开启api：
systemctl restart salt-master.service
systemctl start salt-api.service
11.查看8000端口是否打开：netstat -antlp
11. 在宿主机上测试：
curl -sSk https://172.25.13.1:8000/login -H 'Accept: application/x-yaml' -d username=saltapi -d password=westos -d eauth=pam
12. 通过token测试，此时要保证两个minion开启（server2和3上：systemctl start salt-minion）：
curl -sSk https://172.25.13.1:8000 -H 'Accept: application/x-yaml' -H 'X-Auth-Token':5a5aed14b83035a9a276c1fca9f75a3dcba216f1 -d client=local -d tgt='*' -d fun=test.ping
14.在master（server1上）编辑文件：vim saltapi.py
