文件同步：
其实在做openstack的运维对一些文件的同步其实是很繁琐。有一个配置项或者一行代码的源码文件进行同步。那么现在我们就开始介绍saltstack的文件同步功能
环境说明：操作系统版本：rhel6.5x64
1、master配置同步根目录
在开始saltstack的配置管理之前，要首先指定saltstack所有状态文件的根目录，在master上做如下操作
## 首先修改master的配置文件，指定根目录，注意缩进全部使用两个空格来代替Tab（python规范）## 确定指定的目录是否存在，如果不存在，需要手动来创建目录
[[email protected] ~]# vim /etc/salt/master file_roots: base: - /srv/salt dev: - /srv/salt/dev/ [[email protected] ~]# mkdir -p /srv/salt/dev [[email protected] ~]# ls -ld /srv/salt/dev drwxr-xr-x 2 root root 4096 Feb 3 21:49 /srv/salt/dev
重启master服务
[[email protected] ~]# service salt-master restart Stopping salt-master daemon: [ OK ] Starting salt-master daemon: [ OK ]
2、介绍cp.get_file
首先介绍cp.get_file，用来从master端下载文件到minion的指定目录下，如下
## 在master上创建测试用的文件
[[email protected] ~]# echo ‘This is test file with saltstack module to cp.get_file‘ >/opt/getfile.txt [[email protected] ~]# cat /opt/getfile.txt This is test file with saltstack module to cp.get_file
将文件拷贝到master的同步根目录下
[[email protected] ~]# cp /opt/getfile.txt /srv/salt/
在master上执行文件下发
[[email protected] ~]# salt ‘computer3‘ cp.get_file salt://getfile.txt /tmp/getfile.txt computer3: /tmp/getfile.txt
登录到computer3上查看同步情况
[[email protected] ~]# cat /tmp/getfile.txt This is test file with saltstack module to cp.get_file
分发文件的一些属性：
（1）压缩 gzip
使用gzip的方式进行压缩，数字越大，压缩率就越高，9代表最大的压缩率
[[email protected] ~]# salt ‘computer8‘ cp.get_file salt://getfile.txt /tmp/getfile.txt gzip=9 computer8: /tmp/getfile.txt
（2）创建目录 makedirs（当分发的位置在目标主机上不存在时，自动创建该目录）
[[email protected] ~]# salt ‘computer8‘ cp.get_file salt://getfile.txt /tmp/srv/getfile.txt makedirs=True computer8: /tmp/srv/getfile.txt [[email protected] opt]# ll /tmp/srv/getfile.txt -rw-r--r-- 1 root root 56 Feb 3 22:14 /tmp/srv/getfile.txt
3、grains
先介绍一下grains，这个接口的作用是在minion端的minion服务启动时，调用这个接口，收集minion端的信息，这些信息数据可以在salt的其他模块中直接使用，需要注意的是，这个接口只在minion端的minion服务启动时被调用一次，所以收集的数据是静态的，不会改变的，除非你重启了minion端的服务
grains的基本用法:
[[email protected] ~]# salt ‘computer3‘ grains.ls computer3: - biosreleasedate - biosversion - cpu_flags - cpu_model - cpuarch - defaultencoding - defaultlanguage - domain - fqdn - fqdn_ip4 - fqdn_ip6 - gpus - host - hwaddr_interfaces - id - ip_interfaces - ipv4 - ipv6 - kernel - kernelrelease - localhost - manufacturer - master - mem_total - nodename - num_cpus - num_gpus - os - os_family - osarch - oscodename - osfinger - osfullname - osmajorrelease - osrelease - path - productname - ps - pythonpath - pythonversion - saltpath - saltversion - saltversioninfo - serialnumber - server_id - shell - virtual - zmqversion
使用grains.items模块列出所有可用grains的具体数据
[[email protected] ~]# salt ‘computer3‘ grains.items
