saltstack - salt-api安装配置

环境说明

操作系统：centos 7.0

salt master/minion/版本2014.7.1

Salt-api安装

salt-api 使用pip安装

[[email protected] ~]# pip install CherryPy
[[email protected] ~]# pip install salt-api

Salt-api配置

[[email protected] ~]# cd /etc/pki/tls/certs/  # 生成自签名证书，用于ssl
[[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

Enter pass phrase:       # 输入加密密语，4到8191个字符
Verifying - Enter pass phrase:   # 确认加密密语
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:     # 再次输入密语
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                             # 选填
State or Province Name (full name) []:Shanghai
Locality Name (eg, city) [Default City]:Shanghai

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
[[email protected] private]# ls
localhost.key  localhost_nopass.key

注:

1、 如果make testcert出现错误，删除/etc/pki/tls/private/localhost.key文件，然后再make testcert。

2、 装salt-api的时候，使用curl命令遇到curl: (56) SSL received a record that exceeded the maximum permissible length.可能是CherryPy包的问题。

# 创建用户
[[email protected] private]# useradd -M -s /sbin/nologin saltapi
[[email protected] private]# echo "yao" | passwd saltapi --stdin

# 添加配置文件
[[email protected] ~]# mkdir -p /etc/salt/master.d/      
[[email protected] ~]# vim /etc/salt/master.d/eauth.conf   # 处于安全因素，一般只给特定模块的使用权限，这里给saltapi用户所有模块的使用权限 
external_auth:
  pam:
    saltapi:
      - .*
      
[[email protected] ~]# vim /etc/salt/master.d/api.conf 
rest_cherrypy:
  port: 8888                          #  salt-api 监听端口
  ssl_crt: /etc/pki/tls/certs/localhost.crt          # ssl认证的证书
  ssl_key: /etc/pki/tls/private/localhost_nopass.key
  
[[email protected] ~]# systemctl restart salt-master.service
[[email protected] ~]# systemctl restart salt-api.service

Salt-api使用

1、curl使用

获取token

[[email protected] ~]# curl -k https://172.16.199.249:8888/login -H "Accept: application/x-yaml" -d username=‘saltapi‘ -d password=‘yao‘ -d eauth=‘pam‘
return:
- eauth: pam
  expire: 1427373796.305001
  perms:
  - .*
  - ‘@wheel‘
  - ‘@runner‘
  start: 1427330596.305
  token: ec8d60e3b492e9947e557eefd4112802053432c7
  user: saltapi

查询minion的信息

[[email protected] ~]# curl -k https://172.16.199.249:8888/minions/compute-1 -H "Accept: application/x-yaml"      -H "X-Auth-Token: 9845eab9848c5b5ba72fbad9102532bddab2df7f"   # token是上面获取到的，如果后面跟的请求不包含特定minion id如compute-1，则请求的是所有的minion的信息。
return:
- compute-1:
    SSDs: []
    biosreleasedate: 01/01/2011
    biosversion: 0.5.1
    cpu_flags:
    - fpu
