salt-job管理

在SaltStack里执行任何一个操作都会在master上产生一个jid号，minion端会在cache目录下的proc目录创建一个以jid为名称的文件，这个文件里内容就是此次操作的记录，当操作完成后自动删除。

 

salt踢狗salt-run和moudle两种方式来管理JOB

1.通过salt-run来管理job

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[root@node2 redis-4.0.10]# salt-run -d |grep jobs 'jobs.active:'     Return a report on all actively running jobs from a job id centric         salt-run jobs.active 'jobs.list_job:'         salt-run jobs.list_job 20130916125524463507 'jobs.list_jobs:'     List all detectable jobs and associated functions         salt-run jobs.list_jobs 'jobs.lookup_jid:'         salt-run jobs.lookup_jid 20130916125524463507         salt-run jobs.lookup_jid 20130916125524463507 outputter=highstate 'jobs.print_job:'         salt-run jobs.print_job 20130916125524463507

 

2.可以看到此次的任务号。

[root@node2 redis-4.0.10]# salt 'node1' cmd.run 'sleep 100;whoami'
^CExiting on Ctrl-C
This job's jid is:
20181227213754124155
The minions may not have all finished running and any remaining minions will return upon completion. To look up the return data for this job later run:
salt-run jobs.lookup_jid 20181227213754124155

 

3.查看这个job的运行结果

[root@node2 redis-4.0.10]# salt-run jobs.lookup_jid 20181227213754124155
node1:
root

4.查看这个JOB的详细记录

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

[root@node2 redis-4.0.10]#  salt-run jobs.list_job 20181227213754124155 Arguments:     - sleep 100;whoami Function:     cmd.run Minions:     - node1 Result:     ----------     node1:         ----------         return:             root StartTime:     2018, Dec 27 21:37:54.124155 Target:     node1 Target-type:     glob User:     root jid:     20181227213754124155

 

二。通过saltstack module 来管理JOB

2.1 查看module的用法

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

[root@node2 redis-4.0.10]# salt \* sys.doc saltutil |grep job 'saltutil.find_cached_job:'     Return the data for a specific cached job id         salt '*' saltutil.find_cached_job <job id> 'saltutil.find_job:'     Return the data for a specific job id         salt '*' saltutil.find_job <job id> 'saltutil.kill_job:'     Sends a kill signal (SIGKILL 9) to the named salt job's process         salt '*' saltutil.kill_job <job id>         salt '*' saltutil.runner jobs.list_jobs 'saltutil.signal_job:'     Sends a signal to the named salt job's process         salt '*' saltutil.signal_job <job id> 15 'saltutil.term_job:'     Sends a termination signal (SIGTERM 15) to the named salt job's process         salt '*' saltutil.term_job <job id>

2.2. 接着用这个例子去测试

[root@node2 redis-4.0.10]# salt 'node1' cmd.run 'sleep 100;whoami'

[root@node2 redis-4.0.10]# salt 'node1' saltutil.find_job 20181227220403774993

可以直接kill这个job

[root@node2 redis-4.0.10]# salt 'node1' saltutil.kill_job 20181227220403774993
node1:
Signal 9 sent to job 20181227220656122140 at pid 143225
