salt-api安装配置及使用

标签：salt saltstack

yum install salt-api -y

配置

• 生成自签名证书(用于ssl)

cd  /etc/pki/tls/certs
# 生成自签名证书, 过程中需要输入key密码及RDNs
make testcert
cd /etc/pki/tls/private/
# 解密key文件，生成无密码的key文件, 过程中需要输入key密码，该密码为之前生成证书时设置的密码
openssl rsa -in localhost.key -out localhost_nopass.key

• 创建用于salt-api的用户

useradd -M -s /sbin/nologin salt-api
echo "salt-api" | passwd salt-api —stdin

• 修改/etc/salt/master文件

sed -i ‘/#default_include/s/#default/default/g‘ /etc/salt/master  
mkdir /etc/salt/master.d 

• 新增配置文件/etc/salt/master.d/api.conf

cat /etc/salt/master.d/api.conf
rest_cherrypy:
  port: 8000
  ssl_crt: /etc/pki/tls/certs/localhost.crt
  ssl_key: /etc/pki/tls/private/localhost_nopass.key

• 新增配置文件/etc/salt/master.d/eauth.conf

cat /etc/salt/master.d/eauth.conf  
external_auth:  
  pam:  
    salt-api:  
      - .*  
      - ‘@wheel‘  
      - ‘@runner‘ 

• 启动salt-master and salt-api

systemctl start salt-master
systemctl start salt-api

• 安装一个salt client

yum install salt-minion -y
修改配置
sed -i "/^#master: salt/c master: 192.168.104.76"  /etc/salt/minion
启动 client
systemctl start salt-minion

• master 上接受key

[root@node76 salt]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
node76
Rejected Keys:
[root@node76 salt]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
node76
Proceed? [n/Y] Y
Key for minion node76 accepted.
[root@node76 salt]# salt-key -L
Accepted Keys:
node76
Denied Keys:
Unaccepted Keys:
Rejected Keys:

api使用

• 使用curl 获取token

 curl -k https://192.168.104.76:8000/login -H "Accept: application/x-yaml"  -d username=‘salt-api‘ -d password=‘salt-api‘  -d eauth=‘pam‘
return:
- eauth: pam
  expire: 1520269544.2591
  perms:
  - .*
  - ‘@wheel‘
  - ‘@runner‘
  start: 1520226344.259099
  token: 593a7224f988f28b84d58b7cda38fe5e5ea07d98
  user: salt-api

获取token后就可以使用token通信

==注==：重启salt-api后token改变

• 测试minion端的联通性

  下面功能类似于“salt ‘*‘ test.ping”

curl -k https://192.168.104.76:8000 -H "Accept: application/x-yaml" -H "X-Auth-Token: ded897184a942ca75683276c29d787ea71c207a9" -d client=‘local‘ -d tgt=‘*‘ -d fun=‘test.ping‘ 
return:
- node76: true

• 执行远程命令

  下面功能类似于“salt ‘*‘ cmd.run ifconfig”

curl -k https://192.168.104.76:8000 -H "Accept: application/x-yaml" -H "X-Auth-Token: ded897184a942ca75683276c29d787ea71c207a9" -d client=‘local‘ -d tgt=‘*‘ -d fun=‘cmd.run‘   -d arg=‘uptime‘
return:
- node76: ‘ 13:18:46 up 161 days,  2:23,  1 user,  load average: 0.15, 0.09, 0.10‘

• 使用state.sls

  下面功能类似于“salt ‘*‘ state.sls ifconfig”

 curl -k https://192.168.104.76:8000 -H "Accept: application/x-yaml" -H "X-Auth-Token: ded897184a942ca75683276c29d787ea71c207a9" -d client=‘local‘ -d tgt=‘*‘ -d fun=‘state.sls‘ -d arg=‘ifconfig‘
return:
- node76:
        cmd_|-ifconfig_|-ifconfig_|-run:  
      __run_num__: 0  
      changes:  
        pid: 30954

• 使用Targeting

  下面功能类似于"salt -L ‘192.168.90.61,192.168.90.63‘ test.ping"

 curl -k https://192.168.104.76:8000 -H "Accept: application/x-yaml" -H "X-Auth-Token: ded897184a942ca75683276c29d787ea71c207a9"  -d client=‘local‘ -d tgt=‘node76‘  -d expr_form=‘list‘  -d fun=‘test.ping‘ 
return:
- node76: true

• 以json格式输出

  curl -k https://192.168.104.76:8000 -H "Accept: application/json" -H "X-Auth-Token: ded897184a942ca75683276c29d787ea71c207a9"  -d client=‘local‘ -d tgt=‘node76‘  -d fun=‘cmd.run‘ -d arg=‘uptime‘
  {"return": [{"node76": " 13:25:20 up 161 days,  2:30,  1 user,  load average: 0.01, 0.06, 0.08"}]}
