企业级 ##自动化运维工具Saltstack扩展（salt-api）##
1.【server3】建立服务：
[root@server3 ~]# yum install -y salt-api
[root@server3 ~]# /etc/init.d/salt-minion start
Starting salt-minion:root:server3 daemon: OK2.【server1】建立服务：
[root@server1 master.d]# yum install -y salt-api
[root@server1 private]# pwd
/etc/pki/tls/private
[root@server1 private]# openssl genrsa 1024 > localhost.key
Generating RSA private key, 1024 bit long modulus
.++++++
...................++++++
e is 65537 (0x10001)
[root@server1 private]# ls
localhost.key
[root@server1 private]# cd ..
[root@server1 tls]# cd certs/
[root@server1 certs]# make testcert
umask 77 ; \
/usr/bin/openssl req -utf8 -new -key /etc/pki/tls/private/localhost.key -x509 -days 365 -out /etc/pki/tls/certs/localhost.crt -set_serial 0
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:cn
State or Province Name (full name) []:shaanxi
Locality Name (eg, city) [Default City]:xi'an
Organization Name (eg, company) [Default Company Ltd]:westos
Organizational Unit Name (eg, section) []:linux
Common Name (eg, your name or your server's hostname) []:server1
Email Address []:root@localhost
3.【server1】编辑配置文件：
[root@server1 certs]# cd /etc/salt/
[root@server1 salt]# ls
cloud cloud.maps.d master minion.d proxy
cloud.conf.d cloud.profiles.d master.d minion_id proxy.d
cloud.deploy.d cloud.providers.d minion pki roster
[root@server1 salt]# cd master.d/
[root@server1 master.d]# ls
[root@server1 master.d]# cd ..
[root@server1 salt]# vim master
[root@server1 salt]# cd master.d/
[root@server1 master.d]# vim api.conf
[root@server1 master.d]# vim auth.conf
4.添加用户,设置密码：
[root@server1 master.d]# useradd saltapi
[root@server1 master.d]# passwd saltapi
Changing password for user saltapi.
New password:
BAD PASSWORD: it is based on a dictionary word
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.5.启动服务：
[root@server1 master.d]# /etc/init.d/salt-master stop
Stopping salt-master daemon: [ OK ]
[root@server1 master.d]# /etc/init.d/salt-master status
salt-master is stopped
[root@server1 master.d]# /etc/init.d/salt-master start
Starting salt-master daemon: [ OK ]
[root@server1 master.d]# /etc/init.d/salt-api start
Starting salt-api daemon: [ OK ]
[root@server1 master.d]# netstat -antlp|grep :8000
tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 3244/salt-api -d 6.获取服务token码：
[root@server1 master.d]# curl -sSk https://localhost:8000/login \
> -H 'Accept: application/x-yaml' \
> -d username=saltapi \
> -d password=westos \
> -d eauth=pam
return:
- eauth: pam
expire: 1534628669.2393489
perms:
- .*
- '@wheel'
- '@runner'
- '@jobs'
start: 1534585469.2393479
token: 7e979b37fd9f73a3026ca2a94ab45a71cefcba17
user: saltapi7.进行测试：
[root@server1 master.d]# curl -sSk https://localhost:8000 \
> -H 'Accept: application/x-yaml' \
> -H 'X-Auth-Token: 7e979b37fd9f73a3026ca2a94ab45a71cefcba17' \
> -d client=local \
> -d tgt='*' \
> -d fun=test.ping
return:
- server1: true
server2: true
server3: true8.建立api自动脚本：
[root@server1 ~]# vim salt-api.py

def main():

#sapi.token_id()

推送：[root@server1 ~]# python salt-api.py
在【server3】中关闭nginx服务：
[root@server3 ~]# /etc/init.d/nginx stop
Stopping nginx: [ OK ]
再次推送：[root@server1 ~]# python salt-api.py
在【server3】中ps ax查看进程,发现nginx服务重新打开
