这点时间研究运维自动化，研究到salt-api部分遇到了很多坑，这里记录一下，前面的陆续补上。
1、进程正题，步骤开始：
cd /etc/yum.repos.d/ && wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
yum -y install kernel-firmware kernel-headers perf e2fsprogs
rpm -ivh libyaml-0.1.3-1.4.el6.x86_64.rpm
rpm -ivh PyYAML-3.10-3.1.el6.x86_64.rpm
yum -y install salt-master salt-api
2、
#安装pip:
wget https://pypi.python.org/packages/source/p/pip/pip-1.5.6.tar.gz#md5=01026f87978932060cc86c1dc527903e --no-check-certificate
tar xvfz pip-1.5.6.tar.gz
cd pip-1.5.6
python setup.py build && python setup.py install && pip freeze
#使用pip安装cherrypy:
pip install cherrypy==3.2.3
3、安装openssl证书，因为salt-api是基于证书的，目录不要给错：
[[email protected] tmp]# cd /etc/pki/tls/certs
[[email protected] certs]# make testcert
umask 77 ; \
/usr/bin/openssl genrsa -aes128 2048 > /etc/pki/tls/private/localhost.key
Generating RSA private key, 2048 bit long modulus
..............................................................................................................................................+++
........................................................+++
e is 65537 (0x10001)
Enter pass phrase: #输入6位以上的秘钥
Verifying - Enter pass phrase: #再次输入
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
Enter pass phrase for /etc/pki/tls/private/localhost.key: #再次输入
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) []:nanning
Locality Name (eg, city) [Default City]:ninning
Organization Name (eg, company) [Default Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server‘s hostname) []:
Email Address []:[email protected]
[[email protected] certs]# cd ../private/
[[email protected] private]# openssl rsa -in localhost.key -out localhost_nopass.key
Enter pass phrase for localhost.key:
writing RSA key
建立登录的账号和密码：
[[email protected] private]# useradd -M -s /sbin/nologin xiaoluo
[[email protected] private]# passwd xiaoluo
#salt master配置文件：/etc/salt/master
#取消注释
default_include: master.d/*.conf
mkdir -p /etc/salt/master.d
#saltstack服务端配置:
[[email protected] ~]# cat /etc/salt/master.d/api.conf
rest_cherrypy:
port: 8888
ssl_crt: /etc/pki/tls/certs/localhost.crt
ssl_key: /etc/pki/tls/private/localhost_nopass.key
[[email protected] ~]# cat /etc/salt/master.d/eauth.conf
external_auth:
pam:
xiaoluo:
- .*
- ‘@wheel‘
- ‘@runner‘
＃重启salt－master和salt-api服务:
[[email protected] ~]# /etc/init.d/salt-master restart
Stopping salt-master daemon: [FAILED]
Starting salt-master daemon: [ OK ]
登录获取token:
[[email protected] salt]# curl -k https://192.168.10.205:8888/login -H "Accept: application/x-yaml" -d username=‘xiaoluo‘ -d password=‘123456‘ -d eauth=‘pam‘
return:
- eauth: pam
expire: 1423599495.7932329
perms:
- .*
- ‘@wheel‘
- ‘@runner‘
start: 1423556295.793232
token: 38fc58406d4248abded1abbfa11ce83b68754975
user: xiaoluo
获取token之后,可以使用token通信：
[[email protected] salt]# curl -k https://192.168.10.205:8888/ -H "Accept: application/x-yaml" -H "X-Auth-Token: 38fc58406d4248abded1abbfa11ce83b68754975" -d client=‘local‘ -d tgt=‘*‘ -d fun=‘test.ping‘
return:
- monitor: true
跟salt ‘*‘ test.ping的效果是一样的。这样就实现了salt-api接口的通信。
当然在开发获取数据的时候这样的办法显然是不够灵活的。下面贴出一个salt-api的类:
#!/usr/bin/env python
#coding=utf-8
import urllib2, urllib, json, re
class saltAPI:
def __init__(self):
self.__url = ‘https://192.168.10.205:8888‘ #salt-api监控的地址和端口如:‘https://192.168.186.134:8888‘
self.__user = ‘xiaoluo‘ #salt-api用户名
self.__password = ‘123456‘ #salt-api用户密码
self.__token_id = self.salt_login()
def salt_login(self):
params = {‘eauth‘: ‘pam‘, ‘username‘: self.__user, ‘password‘: self.__password}
encode = urllib.urlencode(params)
obj = urllib.unquote(encode)
headers = {‘X-Auth-Token‘:‘‘}
url = self.__url + ‘/login‘
req = urllib2.Request(url, obj, headers)
opener = urllib2.urlopen(req)
content = json.loads(opener.read())
try:
token = content[‘return‘][0][‘token‘]
return token
except KeyError:
raise KeyError
def postRequest(self, obj, prefix=‘/‘):
url = self.__url + prefix
headers = {‘X-Auth-Token‘ : self.__token_id}
req = urllib2.Request(url, obj, headers)
opener = urllib2.urlopen(req)
content = json.loads(opener.read())
return content[‘return‘]
def saltCmd(self, params):
obj = urllib.urlencode(params)
obj, number = re.subn("arg\d", ‘arg‘, obj)
res = self.postRequest(obj)
print res[0][‘monitor‘][‘biosversion‘]
print res[0][‘monitor‘][‘cpu_model‘]
def main():
#以下是用来测试saltAPI类的部分
sapi = saltAPI()
params = {‘client‘:‘local‘, ‘fun‘:‘grains.items‘, ‘tgt‘:‘*‘}
test = sapi.saltCmd(params)
##运行之后就会打印出grain的值。需要什么值可以直接打印。
测试效果：
[[email protected] python]# python salt-api.py
