saltstack学习-6：文件系统

1，修改配置文件

[root@study02 ~]# vim /etc/salt/master
# The file server works on environments passed to the master, each environment
# can have multiple root directories, the subdirectories in the multiple file
# roots cannot match, otherwise the downloaded files will not be able to be
# reliably ensured. A base environment is required to house the top file.
# Example:
# file_roots:
#   base:
#     - /srv/salt/
#   dev:
#     - /srv/salt/dev/services
#     - /srv/salt/dev/states
#   prod:
#     - /srv/salt/prod/services
#     - /srv/salt/prod/states
#
file_roots:
  base:
    - /srv/salt

base：基础版  ---默认使用这个版本

dev：开发版

prod：产品版

2，创建目录

手工创建，配置文件配置的目录。

测试1：salt远程执行脚本

• 创建脚本

[root@study02 ~]# mkdir /srv/salt
[root@study02 salt]# mkdir etc/script
[root@study02 script]# vim test.sh
[root@study02 script]# cat test.sh 
#!/bin/sh

while true
do 
    sleep 1
    echo 1 >> /tmp/1.log
done

• 执行脚本

[root@study02 script]# salt 'study02' cmd.script salt://etc/script/test.sh

注意：由于这个脚本会一直执行，master在执行这个脚本的时候命令不会退出，需要ctrl+c退出。minion端会生成一个tmp***.sh的脚本，minion实际运行的是这个脚本。所以master退出后不影响minion的运行。

3，创建sls文件

创建top.sls

[root@study02 salt]# cat top.sls 
base:                                           #与base,prod,dev 对应
  'study02':                                   #同步的minion_id
    - test                                        #调用的sls文件名

创建test.sls

[root@study02 salt]# cat test.sls 
syncfile:                                              #名称，可以自定义。如果不写name的话，这里需写成目标地址
  file.managed:                                         #file模块的managed方法
    - source: salt://etc/file/passwd                    #原文件路径
    - user: root                                        #源文件属主
    - group: root                                       #源文件属组
    - mode: 600                                         #源文件权限
    - name: /tmp/passwd                                 #同步目标地址

同步测试

salt 'study02' state.highstate              执行top.sls

salt 'study02' state.sls test                 根目录

salt 'study02' state.sls sls.test            相对路径

salt 'study02' state.sls sls                   默认init.sls

方式一：

[root@study02 salt]# salt 'study02' state.highstate
study02:
----------
          ID: syncfile
    Function: file.managed
        Name: /tmp/passwd
      Result: True

方式二：

[root@study02 salt]# salt 'study02' state.sls test
study02:
----------
          ID: syncfile
    Function: file.managed
        Name: /tmp/passwd
      Result: True

方式三：将所有的sls文件放到一个目录

[root@study02 salt]# tree 
.
├── etc
│   ├── file
│   │   └── passwd
│   └── script
│   └── test.sh
├── sls
│   └── test.sls
├── test.sls
└── top.sls

执行同步命令

[root@study02 salt]# salt 'study02' state.sls sls.test
study02:
----------
          ID: syncfile
    Function: file.managed
        Name: /tmp/passwd
      Result: True
     Comment: File /tmp/passwd updated

方式4：默认执行init.sls，程序会自动补充文件后缀（.sls）

[root@study02 salt]# tree
.
├── etc
│   ├── file
│   │   └── passwd
│   └── script
│   └── test.sh
├── sls
│   ├── init.sls
│   └── test.sls
├── test.sls
└── top.sls

init.sls功能查询主机名：

[root@study02 sls]# cat init.sls 
hostname:
  cmd.run

测试结果：

[root@study02 sls]# salt 'study02' state.sls sls
study02:
----------
          ID: hostname
    Function: cmd.run
      Result: True
     Comment: Command "hostname" run
     Started: 17:10:26.074874
    Duration: 9.38 ms
     Changes:   
              ----------
              pid:
                  30307
              retcode:
                  0
              stderr:
              stdout:
                  study02
