实施如下：
一、测试是否能管理client
使用模块cmd.run 可以查看到client的ip地址
[root@salt_server ~]# salt '*' cmd.run 'ip a'
salt_client1:
lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:f4:4f:0b brd ff:ff:ff:ff:ff:ff
inet 192.168.100.245/24 brd 192.168.100.255 scope global eth0
inet6 fe80::20c:29ff:fef4:4f0b/64 scope link
valid_lft forever preferred_lft forever
[root@salt_server ~]#
二、查看版本
[root@salt_server ~]# salt --versions-report
Salt: 2014.1.0
Python: 2.6.6 (r266:84292, Jun 18 2012, 14:18:47)
Jinja2: unknown
M2Crypto: 0.20.2
msgpack-python: 0.1.13
msgpack-pure: Not Installed
pycrypto: 2.0.1
PyYAML: 3.09
PyZMQ: 2.2.0.1
ZMQ: 3.2.4
[root@salt_server ~]#
关于salt的命令 可以用salt -h 来查看具体用法
三、简单使用salt
salt 在语句的后面加个 -t 时间，就可以做超时控制：
[root@salt_server ~]# salt \* cmd.run 'sleep 3; echo ok' -t 3
salt_client1:
ok
[root@salt_server ~]#
salt \* 代表所有的在线客户端，离线的是无法显示出来的
使用用shell来表示salt：
[root@salt_server ~]# salt 'salt_client1' cmd.run 'dir'
salt_client1:
anaconda-ks.cfg install.log.syslog
epel-release-6-8.noarch.rpm rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
install.log
[root@salt_server ~]#
用正则来查看以salt开头的所有主机的目录
[root@salt_server ~]# salt 'salt_*' cmd.run 'dir'
salt_client1:
anaconda-ks.cfg install.log.syslog
epel-release-6-8.noarch.rpm rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
install.log
[root@salt_server ~]#
使用正则E来查看主机
[root@salt_server ~]# salt -E 'salt_client*' test.ping
salt_client1:
True
salt_client2:
True
[root@salt_server ~]#
使用-L 来用列表方式来表示
[root@salt_server ~]# salt -L 'salt_client1,salt_client2' test.ping
salt_client1:
True
salt_client2:
True
[root@salt_server ~]#
-N 是查看组。首先我们来添加组
修改配置文件master vim /etc/salt/master
nodegroups:
salt_group1: 'L@salt_client1,salt_client2'
salt_group2: 'salt_client1'
[root@salt_server ~]# /etc/rc.d/init.d/salt-master restart
Stopping salt-master daemon: [ OK ]
Starting salt-master daemon: [ OK ]
[root@salt_server ~]#
等一分钟 然后在查看
-N 参数
salt_client1 这里指组名
test.ping 这里指命令
[root@salt_server ~]# salt -N salt_group1 test.ping
salt_client1:
True
salt_client2:
True
[root@salt_server ~]# salt -N salt_group2 test.ping
salt_client1:
True
[root@salt_server ~]#
[root@salt_server ~]# salt -N salt_group1 cmd.run 'hostname'
salt_client1:
salt_client1
salt_client2:
salt_client2
[root@salt_server ~]#
测试所有主机是否能连接
[root@salt_server ~]# salt '*' test.ping
salt_client1:
True
测试salt_client1是否能连接
[root@salt_server ~]# salt 'salt_client1' test.ping
salt_client1:
True
[root@salt_server ~]#
[root@salt_server ~]# salt-syndic -l debug
salt '*' -b 10 test.ping
salt -G 'os:RedHat' --batch-size 25% apache.signal restart
四、使用grains 插件
grains 是salt客户端自己收集机器的相关信息，以及特称，在服务端我们可以使用-G参数来查看
使用-G来应用salt
这个参数很强大会根据用grair来指定最新的grains z这个参数和puppet里面的facter差不多
查看帮助如下:
-G, --grain Instead of using shell globs to evaluate the target
use a grain value to identify targets, the syntax for
the target is the grain key followed by a
globexpression: "os:Arch*"
我的系统是CentOS我就输入CentOS。
[root@salt_server ~]# salt -G 'os:CentOS' test.ping
salt_client1:
True
[root@salt_server ~]#
[root@salt_server ~]# salt '*' grains.item os
salt_client1:
os: CentOS
[root@salt_server ~]#
[root@salt_server ~]# salt -G 'cpuarch:x86_64' grains.item num_cpus
salt_client1:
num_cpus: 1
salt_client2:
num_cpus: 1
[root@salt_server ~]#
[root@salt_server ~]# salt '*' grains.items 查看有多少项目参数
[root@salt_server ~]# salt '*' grains.ls 查看有哪些参数
[root@salt_server salt]# salt 'salt_client1' grains.items 查看某个机器的基本信息
salt_client1:

五、使用salt来同步一个第一个简单的文件
[root@salt_server ~]# mkdir /srv/salt/base -p
[root@salt_server ~]# cd /srv/salt/base
[root@salt_server salt]# echo "test salt first file" >> first.txt
[root@salt_server salt]# salt 'salt_client1' cp.get_file salt://first.txt /home/first.txt
salt_client1:
/home/first.txt
[root@salt_server salt]#
在客户端查看
[root@salt_client1 home]# pwd
/home
[root@salt_client1 home]# cat first.txt
test salt first file
[root@salt_client1 home]#
[root@salt_server salt]# salt-run jobs.list_jobs 最近操作文件的配置
[root@salt_server salt]# salt-run jobs.lookup_jid 20140317113642863799 后面是返回值 配合第一个一起使用
六、使用salt来查看客户端系统相关信息
查看当前是否有任务运行
[root@salt_server salt]# salt-run jobs.active
{}
[root@salt_server salt]#
查看所有的主机名
[root@salt_server salt]# salt '*' cmd.run hostname
salt_client1:
salt_client1
[root@salt_server salt]#
查看系统
[root@salt_server salt]# salt '*' grains.item os
salt_client1:
os: CentOS
[root@salt_server salt]#
查看客户端IP地址
[root@salt_server salt]# salt 'salt_client1' network.interfaces

七、使用salt来管理系统软件包
安装包
[root@salt_server salt]# salt 'salt_client1' pkg.install telnet
salt_client1:
----------
telnet:
----------
new:
0.17-47.el6
old:
[root@salt_server salt]#
查看安装的包，这里安装的包指的不是用salt安装的包 而是全部的包
[root@salt_server salt]# salt 'salt_client1' pkg.list_pkgs
删除刚安装的包
[root@salt_server salt]# salt 'salt_client1' pkg.remove telnet
salt_client1:
----------
telnet:
----------
new:
sal
old:
0.17-47.el6
[root@salt_server salt]#
在客户端查看
[root@salt_client1 salt]# rpm -qa | grep telnet
telnet-0.17-47.el6.x86_64
[root@salt_client1 salt]# telnet
telnet> ^C
[root@salt_client1 salt]# rpm -qa | grep telnet
[root@salt_client1 salt]#
查看repos内容:
[root@salt_server salt]# salt 'salt_client1' pkg.list_repos
salt_client1:
----------
source:
----------
baseurl:
file:///mnt/CentOS6.3
enabled:
1
file:

file:///mnt/saltstack
enabled:
1
file:
/etc/yum.repos.d/source.repo
gpgcheck:

[root@salt_server salt]#
如果想查看所有minion的链接情况，我们可以用如下命令来查看
[root@salt_server ~]# salt '*' test.ping
salt_client1:
True
[root@salt_server ~]# salt-run manage.status
down:
up:
- salt_client1
[root@salt_server ~]#
删除客户端的一个用户：
[root@salt_server ~]# salt 'salt_client1' webutil.userdel /etc/passwd kcc
salt_client1:
- Deleting password for user kcc
[root@salt_server ~]#
Space-delimited arguments to the function:
[root@salt_server ~]# salt \* cmd.exec_code python 'import sys; print sys.version'
