现在分享一下我对0.16版本salt的学习笔记
一、安装
1、在ubuntu系统安装
添加源
debhttp://debian.saltstack.com/debian wheezy-saltstack main
把这个源放到/etc/apt/sources.list
更新源
apt-get update
安装服务端或者客户端
apt-get installsalt-master
apt-get installsalt-minion
2、redhat或者centos的话，安装使用需要安装第三个源
如果你是5版本
|
1
|
wget http:
//dl.cpis-opt.com/huanw/shencan/epel-release-5-4.noarch.rpm && rpm -vih epel-release-5-4.noarch.rpm
|
如果是6版本，使用
|
1
2
3
|
wget http:
//download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
yum install salt-master
yum install salt-minion
|

The Salt master communicates
with
the minions using an AES-encrypted ZeroMQ connection. These communications are done over ports
4505
and
4506
, which need to be accessible on the master only. This document outlines suggested firewall rules
for
allowing these incoming connections to the master.
Note
No firewall configuration needs to be done on Salt minions. These changes refer to the master only.
|
二、配置
在master端配置
|
1
2
|
vim /etc/salt/master
interface
:
192.168
.
56.102
|
写成你本机的ip
在slave端配置
|
1
2
|
vim /etc/salt/minion
master:
192.168
.
56.102
|
写你服务端的ip
|
1
|
id: localhost
|
是注明自己的标示。
客户端/etc/init.d/salt-minion start 日志文件默认是这个/var/log/salt/minion
服务端/etc/init.d/salt-master start 日志文件默认是这个/var/log/salt/master

localhost:
True
server.hadoop.com:

|
先前使用*代表所有机器，如果想单独的话，可以使用
|
1

|
[root@centos salt]# salt
'localhost'
cmd.run hostname
localhost:
centos
|
如果想运行多个的话，可以使用-L
|

|
[root@centos salt]# salt -L
'server.hadoop.com,localhost'
cmd.run hostname
server.hadoop.com:

|
还可以使用正则
|
1

3
|
[root@centos salt]# salt -E
'server*'
cmd.run hostname
server.hadoop.com:
server.hadoop.com
|
-G 这个参数很强大会根据默认的grain的结果来指定最新 grain这个东西就像puppet里面的facter这个东西

|
nodegroups:
group1:
'localhost'
group2:

可以把localhost分给group1，server.hadoop.com分给group2
然后重启salt-master

查看你repos（由于内容过多，我就只列出命令了）
|
1
|
salt
'localhost'
pkg.list_repos
|
三、配置类似puppet操作
由于我的master上的存放信息目录是在/var/salt上
|
1
2
3
|
file_roots:
base:
- /
var
/salt/
|
所以进入换个目录
下面是我的配置
|
1
2
3
4
|
[root@centos salt]# cat top.sls
base:
'*'
: #对象名，我使用*代表所有
- vim #资源文件名
|
如果你的资源文件存放在一个目录里，比如在/var/salt/apache/vim.sls，
那么可以写为
|
1
|
-apache.vim
|
代表apache目录下的vim.sls
下面测试

[root@centos salt]# cat top.sls
base:
'localhost'
:
- echoping.echoping#代表echoping目录下的echoping.sls文件
[root@centos echoping]# pwd
/
var
/salt/echoping
[root@centos echoping]# cat echoping.sls
echoping: #id宣告
pkg: #安装包管理
- name: echoping #安装哪个软件
- installed #要求是安装
service: #服务管理
- name: httpd #指定服务
- running #服务运行状态
- reload: True #是否重启
- watch: #如果下面文件发生变化，就重启
- file: /tmp/test_echoping.conf #监控的文件地址
/tmp/test_echoping.conf: #宣告
file.managed: #文件管理
- source: salt:
//echoping/test_echoping.conf #源数据在哪里
- user: root #用户
- group: root #组
- mode:
644
#权限
- backup: minion #备份一份
|
运行的话，可以使用salt 'localhost' state.highstate
注意，如果需要把服务设置为开机启动可以使用- enable:True
由于我设置的是有变化就重启http，所以先查看http的状态

如果想让salt能想puppet那样定时自动的获取配置，可以在/etc/salt/minion里配置
|
1
2
3
4
|
schedule:
highstate:
function
: state.highstate
minutes:
60
|
然后重启salt-minion
请注意，在服务端可以使用salt 'localhost' state.highstate，在客户端的话，使用salt-callstate.highstate
如果使用grains来区分不同的系统安装不同的东东，可以使用下面（比如安装apache，在centos里安装httpd，在ubuntu里安装apache2）

注意，如果你想使用命令的话，可以使用cmd.wait

echo-msg:
cmd.wait:

'this is test'

自定义模块
查看你master上的file_root路径，比如我的为
|
1
2
3
|
file_roots:
base:
- /
var
/salt/
|
所以在/var/salt里创建个_modules
|
1
|
mkdir /
var
/salt/_modules
|
然后进入目录编写模块
|
1
2
3
4
5
6
7
8
9
|
cd /
var
/salt/_modules
[root@centos _modules]# cat dl.py
def msg():
msg=
'this is test message'
return
msg
def time():
import
time
a=time.asctime()
return
a
|
必须以.py结尾
然后同步到minion里（使用saltutil.sync_all）

[root@centos _modules]# salt

- modules.dl
|_

|_
|_
localhost:
|_

[root@centos _modules]# salt

server.hadoop.com:

当然还可以直接调用salt的模块
调用先有的module来显现自定义module中需要的功能saltsalt内置的一个字典,包含了所有的salt的moudle
|

def cmd(cmd):
return
__salt__[
'cmd.run'
](cmd)

下面是一些关于client的描述
|
1

|
Python client API
Salt
is
written to be completely API centric, Salt minions and master can be built directly into third party applications
as
a communication layer. The Salt client API
is
very straightforward.
|
运行单个命令
|

10
|
>>>
import
salt.client
>>> a=salt.client.LocalClient()
>>> a
<salt.client.LocalClient object at
0x1ad8f10
>
>>> a.cmd(
"localhost"
,
"test.ping"
)
{
'localhost'
: True}
>>> a.cmd(
"*"
,
"test.ping"
)
{
'server.hadoop.com'
: True,
'localhost'
: True}
>>> a.cmd(
"*"
,
"dl.time"
)
{
'server.hadoop.com'
:
'Wed Aug 14 09:53:22 2013'
,
'localhost'
:
'Wed Aug 14 09:53:22 2013'
}
|
运行多个命令
|

|
>>> a.cmd(
'*'
,[
'cmd.run'
,
'test.ping'
,
'dl.time'
],[[
'hostname'
],[],[]])
{
'server.hadoop.com'
: {
'test.ping'
: True,
'dl.time'
:
'Wed Aug 14 10:01:35 2013'
,
'cmd.run'
:
'server.hadoop.com'
},
'localhost'
: {
'test.ping'
: True,
'dl.time'
:
'Wed Aug 14 10:01:35 2013'
,
'cmd.run'
:
'centos'
}}
