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
# Copyright (C) 2004 Tuatha de Dana
# 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.
Started: 18:03:39.272417

Changes:

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】
