Saltstack_使用指南13_runner的job和manage与execution的saltutil

 

1. 主机规划

 

salt 版本

1 [root@salt100 ~]# salt --version
2 salt 2018.3.3 (oxygen)
3 [root@salt100 ~]# salt-minion --version
4 salt-minion 2018.3.3 (oxygen)

 

job 管理文档

https://docs.saltstack.com/en/latest/topics/jobs/index.html    

 

runner modules文档

salt runners类似于salt execution modules，但是前者是在master端执行的，后者是在minion端执行的。

1 https://docs.saltstack.com/en/latest/ref/cli/salt-run.html    
2 https://docs.saltstack.com/en/latest/ref/runners/index.html    
3 https://docs.saltstack.com/en/latest/ref/runners/all/index.html    

 

execution modules文档

1 https://docs.saltstack.com/en/latest/ref/modules/all/index.html    
2 https://docs.saltstack.com/en/latest/ref/modules/all/salt.modules.saltutil.html    

 

注意事项

修改了master或者minion的配置文件，那么必须重启对应的服务。

 

2. salt-run  jobs常用方法

1 # 返回正在活动中的jobs信息
2 salt-run jobs.active    
3 # 列出所有可检测的jobs和相关functions
4 salt-run jobs.list_jobs        
5 # 根据 jid 列出指定的job
6 salt-run jobs.list_job 20190111160734604439        
7 # 返回以前执行job的打印输出【回看当时job输出的信息】
8 salt-run jobs.lookup_jid 20190111170928354082    

 

示例信息如下

 1 [root@salt100 ~]# salt-run jobs.active
 2 20190111170928354082:
 3     ----------
 4     arguments:
 5         - df -h && sleep 30
 6     function:
 7         cmd.run
 8     returned:
 9     running:
10         |_
11           ----------
12           salt01:
13               2640
14     starttime:
15         2019, jan 11 17:09:28.354082
16     target:
17         salt01
18     target-type:
19         glob
20     user:
21         root
22 20190111170930696130:
23     ----------
24     arguments:
25         - whoami && sleep 30
26     function:
27         cmd.run
28     returned:
29     running:
30         |_
31           ----------
32           salt01:
33               2646
34     starttime:
35         2019, jan 11 17:09:30.696130
36     target:
37         salt01
38     target-type:
39         glob
40     user:
41         root
42 [root@salt100 ~]# salt-run jobs.lookup_jid 20190111170928354082  # 显示信息如下
43 salt01:
44     filesystem      size  used avail use% mounted on
45     /dev/sda3        18g  2.1g   16g  12% /
46     devtmpfs        901m     0  901m   0% /dev
47     tmpfs           911m   12k  911m   1% /dev/shm
48     tmpfs           911m  9.6m  902m   2% /run
49     tmpfs           911m     0  911m   0% /sys/fs/cgroup
50     /dev/sda1       197m  113m   85m  58% /boot
51     tmpfs           183m     0  183m   0% /run/user/1001

 

3. salt-run  manage常用方法

salt的常规管理功能，比如查看哪些hosts上线或下线

1 salt-run manage.list_state
2 salt-run manage.alived 
3 salt-run manage.status
4 salt-run manage.down
5 salt-run manage.up
6 salt-run manage.versions

 

4. saltutil模块

1 # 返回minion端正在执行salt 进程的数据
2 salt '*' saltutil.running 
3 # 杀掉指定 jid【jobid】进程
4 salt '*' saltutil.kill_job 20190111180228662382

 

示例信息

 1 [root@salt100 ~]# salt '*' saltutil.running
 2 salt03:
 3 salt01:
 4     |_
 5       ----------
 6       arg:
 7           - whoami && sleep 300
 8       fun:
 9           cmd.run
10       jid:
11           20190111175718092279
12       pid:
13           2825
14       ret:
15       tgt:
16           salt01
17       tgt_type:
18           glob
19       user:
20           root
21 salt02:
22 salt100:
23 [root@salt100 ~]# salt '*' saltutil.kill_job 20190111180228662382
24 salt03:
25 salt02:
26 salt100:
27 salt01:
28     signal 9 sent to job 20190111180228662382 at pid 2882 

 

5. 实战应用

5.1. master执行

1 [root@salt100 master]# salt 'salt01' cmd.run 'whoami && sleep 300'  # 执行后，然后 ctrl+c 终端
2 ^c
3 exiting gracefully on ctrl-c
4 this job's jid is: 20190111223139879350
5 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 the following command:
6 
7 salt-run jobs.lookup_jid 20190111223139879350
8 [root@salt100 master]# 
9 [root@salt100 master]# salt '*' cmd.run 'whoami && sleep 300'  # 第二次执行

 

5.2. 查看当前活动的jobs

通过如下方式查看可知，虽然之前 ctrl + c 了，但是minion端还是在执行相应的进行。

 

5.2.1. 方式一

 1 [root@salt100 ~]# salt-run jobs.active  
 2 20190111223139879350:
