saltstack 添加计划任务-原创手记-慕课网

前面己经说过如何安装saltstack，在平时己经体验了它的强大，下面来说一下平时常用的cp模块及cron与sls文件的书写

一、salt.modules.cp

1、复制文件[我使用最多的]

格式：

salt.modules.cp.get_file(path, dest, saltenv='base', makedirs=False, template=None, gzip=None, env=None,**kwargs)

常用参数说明：

path:表示salt-master的file_roots的路径下的源文件

dest:表示salt-minion的路径下文件（可以指定文件名，也可以不指定，但不指定【有时】会报错）

saltenv:salt-master部署到的环境，可以/etc/salt/master文件的file_roots自行指定，默认为base

makedirs:类型为布尔型，True表示目录不存在创建，False表示不创建

template: 指定模板,常用的有jinja。。。

gzip:压缩级别

例子：

salt '192.168.2.36-CentOS.backup.test.backend' cp.get_file salt://crontab/bak_sys.py /root/bak_sys.py makedirs=True gzip=9

2、复制目录

格式：

salt.modules.cp.get_dir(path, dest, saltenv='base', template=None, gzip=None, env=None, **kwargs)

注：path在此处表示目录，如果你不想将path复制到dest之下,那么指定到dest的上一级就好

例子：

#salt 'test-201' cp.get_dir salt://crontab /root makedirs=True

test-201:

- /root/crontab/Insert_Outgoing_Mail_Total.py

- /root/crontab/Redis_config.py

.....

3、查看文件内容

格式：

salt.modules.cp.get_file_str(path, saltenv='base', env=None)

例子：

[root@report copy_crontab_file]# salt 'test-201' cp.get_file_str salt://crontab/delete_mysql_rsyslog.sh

test-201:

#!/bin/bash

# Database maintance script which can be used for rsyslog

# and phplogcon default database schema.

# Michael Mansour suggested it to be included - thx!

# This program was original part of of PHPloghost

# some modifications for rsyslog by mmeckelein at 2007-08-08

# 2007-08-13 mmeckelein: added dbhost and some other improvements

# suggested by Michael Mansour - thx a lot!

.....

二、salt.modules.cron

1、添加计划任务

格式：

salt.modules.cron.set_job(user, minute, hour, daymonth, month, dayweek, cmd, comment=None,identifier=None)

参数说明：

user:用户；剩下的表示分、时、日、月、周、命令、任务描述信息

例子：

salt \* cron.set_job root '0' '03' '*' '*' '*' '/bin/bash /root/crontab/rsync_mysql_backup.sh' 'remote backup mysql data to xxxxxxx/backup/local_mysql_backup/ by king.gp'

说明:每一个参数项都要用引号括起来。

2、删除计划任务

格式：

salt.modules.cron.rm_job(user, cmd, minute=None, hour=None, daymonth=None, month=None,dayweek=None, identifier=None)

例子：

salt '*' -b 3 cron.rm_job root '/root/crontab/rsync_mysql_backup.sh'

三、添加计划任务states文件版本。

注：

要在salt-master端设置file_roots （略）

在file_roots指定的目录下创建top.sls文件

定义init.sls文件

1、我们第二步开始，file_roots设置top文件

[root@report /]# egrep -v "^$|^#" /etc/salt/master

file_roots:

base:

- /home/sysadmin/yunwei

- /home/sysadmin/yunwei/workspace

2、创建top.sls文件

[root@report workspace]# pwd

/home/sysadmin/yunwei/workspace

[root@report workspace]# cat top.sls

base:

"test-201":

- install_python_ext

- add_crontab_file

注：如果file_roots指向多个路径，salt则取它们的合集

3、定义init.sls文件

注：也是可以直接在top.sls的同级目录写sls文件的，但这样到后期要维护太多的文件，而且看上会会很乱，如果定义多级目录，就可在同名目录中写【init.sls】文件了

[root@report workspace]# cd add_crontab_file/

[root@report add_crontab_file]# pwd

/home/sysadmin/yunwei/workspace/add_crontab_file

[root@report add_crontab_file]# cat init.sls

/root/crontab:

file.directory:

- user: root

- group: root

- mode: 755

- makedirs: True

/root/crontab/clean_mail_local_mysql_history_data.sh:

cron.present:

- user: root

- minute: 30

- hour: 23

- daymonth: 28

- comment: 'clean local mysql data info by king.gp'

/root/crontab/Insert_Outgoing_Mail_Total.py:

cron.present:

- user: root

- minute: 0

- hour: 23

- comment: 'mail outgoing total by king.gp'

/root/crontab/rsync_mysql_backup.sh:

cron.present:

- user: root

- minute: 0

- hour: 3

- comment: 'remote backup mysql data to 192.168.3.34/backup/local_mysql_backup/ by king.gp'

/root/crontab/rsync_redis_backup.sh:

cron.present:

- user: root

- minute: 0

- hour: '*/2'

- comment: 'remote backup redis data to 192.168.3.37/archive/redis_backup/ by king.gp'

/root/crontab/delete_mysql_rsyslog.sh:

cron.present:

- user: root

- minute: 0

- hour: 1

- comment: 'del local mysql syslog data'

注:由于有一个脚本用python写的，还要安装一些python的扩展包

[root@report copy_crontab_file]# cd ..

[root@report workspace]# cd install_python_ext/

[root@report install_python_ext]# pwd

/home/sysadmin/yunwei/workspace/install_python_ext

[root@report install_python_ext]# cat init.sls

python_ext:

pkg.installed:

- pkgs:

- python-setuptools

- python-pip

- MySQL-python

4、定义runner文件

[root@report workspace]# pwd

/home/sysadmin/yunwei/workspace

[root@report workspace]# cat cron_runner.sls

python_ext:

salt.state:

- tgt: 'test-201'

- highstate: True

corn_exec:

salt.state:

- tgt: 'test-201'

- highstate: True

- require:

- salt: python_ext

5、测试runner文件

[root@report workspace]# salt-run state.orchestrate cron_runner test=Ture

report.chinadns.net_master:

----------

ID: python_ext

Function: salt.state

Result: True

Comment: States ran successfully. No changes made to test-201.

Started: 18:00:13.372399

Duration: 8079.834 ms

Changes:

----------

ID: corn_exec

Function: salt.state

Result: True

Comment: States ran successfully. No changes made to test-201.

Started: 18:00:21.452916

Duration: 8101.168 ms

Changes:

Summary

------------

Succeeded: 2

Failed: 0

------------

Total states run: 2

注：此处我是先将计划任务的目录拷贝到test-201上

salt 'test-201' cp.get_file salt://crontab /root makedirs=True

6、执行定义好的runner文件

[root@report workspace]# salt-run state.orchestrate cron_runner

report.chinadns.net_master:

----------

ID: python_ext

Function: salt.state

Result: True

Comment: States ran successfully. No changes made to test-201.

Duration: 8102.33 ms

Changes:

Summary

------------

Succeeded: 2

Failed: 0

------------

Total states run: 2

7、查看结果

[root@report workspace]# salt 'test-201' cron.ls root

test-201:

注：最通用的还是写piller，但现在我还是用不明白，就不丢人了！

四、总结

1、多看文档，多总结;【E文没过级，but我有梯子】

2、如果别人发现你用方法很蠢，请接受;

3、多动手。【能打就不要吵】
