SaltStack-job管理

一、salt执行结果默认返回给master端

1、job cache

存放位置

# Directory to store job and cache data:# This directory may contain sensitive data and should be protected accordingly.##cachedir: /var/cache/salt/master# Set the number of hours to keep old job information in the job cache:#keep_jobs: 24# The number of seconds to wait when the client is requesting information# about running jobs.#gather_job_timeout: 10

2、将cache存入数据库

（1）安装数据库连接模块

安装连接mysql的模块MySQL-pythonyum install -y MySQL-python

（2）配置数据库连接

在master上配置连接

直接在master的配置文件后面追加内容vim /etc/salt/mastermaster_job_cache: mysqlmysql.host: '192.168.56.11'mysql.user: 'salt'mysql.pass: '123456'mysql.db: 'salt'mysql.port: 3306

（3）重启salt-master

systemctl restart master

（4）验证是否写入数据库

执行如下命令[root@linux-node1 /srv/salt/prod/bbs]# salt '*' cmd.run 'whoami'linux-node2.example.com:    rootlinux-node1.example.com:    root

登录数据库mysql -h 192.168.56.11 -usalt -p123456MariaDB [(none)]> use salt;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -A*************************** 9. row ***************************       fun: cmd.run       jid: 20161109091010973295    return: "root"        id: linux-node2.example.com   success: 1  full_ret: {"fun_args": ["whoami"], "jid": "20161109091010973295", "return": "root", "retcode": 0, "success": true, "cmd": "_return", "_stamp": "2016-11-09T01:10:11.064745", "fun": "cmd.run", "id": "linux-node2.example.com"}alter_time: 2016-11-09 09:10:11*************************** 10. row ***************************       fun: cmd.run       jid: 20161109091010973295    return: "root"        id: linux-node1.example.com   success: 1  full_ret: {"fun_args": ["whoami"], "jid": "20161109091010973295", "return": "root", "retcode": 0, "success": true, "cmd": "_return", "_stamp": "2016-11-09T01:10:11.146238", "fun": "cmd.run", "id": "linux-node1.example.com"}alter_time: 2016-11-09 09:10:1110 rows in set (0.00 sec)

3、job查看

先执行一个命令，比如

salt '*' cmd.run 'ping www.baidu.com'

在执行job查看命令

[root@linux-node1 ~]# salt '*' saltutil.runninglinux-node2.example.com:    |_      ----------      arg:          - ping www.baidu.com      fun:          cmd.run      jid:          20161109091517283293      pid:          6049      ret:      tgt:          *      tgt_type:          glob      user:          rootlinux-node1.example.com:    |_      ----------      arg:          - ping www.baidu.com      fun:          cmd.run      jid:          20161109091517283293      pid:          6269      ret:      tgt:          *      tgt_type:          glob      user:          root

停止job，可以使用如下方法

[root@linux-node1 ~]# salt '*' saltutil.kill_job 20161109091517283293linux-node2.example.com:    Signal 9 sent to job 20161109091517283293 at pid 6049linux-node1.example.com:    Signal 9 sent to job 20161109091517283293 at pid 6269[root@linux-node1 ~]# salt '*' saltutil.runninglinux-node2.example.com:linux-node1.example.com:

4、master端cache

存放位置

[root@linux-node1 /var/cache/salt/master]# lsfile_lists  jobs  minions  proc  queues  roots  syndics  tokens[root@linux-node1 /var/cache/salt/master]# pwd/var/cache/salt/master[root@linux-node1 /var/cache/salt/master]# tree.├── file_lists│   └── roots│       ├── base.p│       └── prod.p├── jobs│   ├── 6c│   │   └── 9f646ec75df0bd0ec29760ef0dee7a│   │       ├── jid│   │       └── linux-node1.example.com│   │           └── return.p│   ├── 90│   │   └── d3646e58dd82e103973eb889af96d1│   │       └── jid│   ├── d4│   │   └── 74a5b7f1ebf41c84c714d2ad8fda85│   │       ├── jid│   │       └── linux-node1.example.com│   │           └── return.p│   └── e3│       └── d2ffbc8e72a923205126c07c9e1e55│           ├── jid│           └── linux-node1.example.com│               └── return.p

二、jobs管理组件

一个方便管理jobs的系统：runners.jobs

列出job cache中的job[root@linux-node1 /var/cache/salt/master]# salt-run jobs.list_jobs[WARNING ] /usr/lib/python2.7/site-packages/salt/grains/core.py:1493: DeprecationWarning: The "osmajorrelease" will be a type of an integer.20161109090923312794:    ----------    Arguments:        - whoami    Function:        cmd.run    StartTime:        2016, Nov 09 09:09:23.312794    Target:        *    Target-type:        glob    User:        root

查看某个job的返回

[root@linux-node1 ~]# salt-run jobs.lookup_jid 20161109093137760714linux-node1.example.com:    PING www.a.shifen.com (119.75.218.70) 56(84) bytes of data.    64 bytes from 119.75.218.70: icmp_seq=1 ttl=128 time=9.78 ms    64 bytes from 119.75.218.70: icmp_seq=2 ttl=128 time=4.65 ms    64 bytes from 119.75.218.70: icmp_seq=3 ttl=128 time=8.26 ms        --- www.a.shifen.com ping statistics ---    3 packets transmitted, 3 received, 0% packet loss, time 2010ms    rtt min/avg/max/mdev = 4.657/7.569/9.786/2.150 ms

可以使用salt-run查看当前up和down的minion

[root@linux-node1 ~]# salt-run manage.statusdown:up:    - linux-node1.example.com    - linux-node2.example.com
