简介
SaltStack是一个服务器基础架构集中化管理平台，具备配置管理、远程执行、监控等功能，一般可以理解为简化版的puppet和加强版的func。SaltStack基于Python语言实现，结合轻量级消息队列（ZeroMQ）与Python第三方模块（Pyzmq、PyCrypto、Pyjinjia2、python-msgpack和PyYAML等）构建。
通过部署SaltStack环境，我们可以在成千上万台服务器上做到批量执行命令，根据不同业务特性进行配置集中化管理、分发文件、采集服务器数据、操作系统基础及软件包管理等，SaltStack是运维人员提高工作效率、规范业务配置与操作的利器。

特性
(1)、部署简单、方便；
(2)、支持大部分UNIX/Linux及Windows环境；
(3)、主从集中化管理；
(4)、配置简单、功能强大、扩展性强；
(5)、主控端（master）和被控端（minion）基于证书认证，安全可靠；
(6)、支持API及自定义模块，可通过Python轻松扩展。
三种运行方式：
Local，Master/Minion ,Salt SSH
三大功能：
远程执行，配置管理，云管理
操作
安装：
IP地址 | 角色 |
192.168.20.93 | master |
192.168.20.172 | minion |
master 端：
yum install salt-master salt-minion -y
minion端：
yum install salt-minion -y
开机自启动：
chkconfig salt-minion on
启动master：
/etc/init.d/salt-master start
编译：vim /etc/salt/minion（master端和minion端都要配置）
配置17行：master 的主机IP地址
master: 192.168.20.93
id：XXXXXXXX #在master端显示的名称。
Master与Minion认证与快速入门
(1)、minion在第一次启动时，会在/etc/salt/pki/minion/（该路径在/etc/salt/minion里面设置）下自动生成minion.pem（private key）和 minion.pub（public key），然后将 minion.pub发送给master。
(2)、master在接收到minion的public key后，通过salt-key命令accept minion public key，这样在master的/etc/salt/pki/master/minions下的将会存放以minion id命名的 public key，然后master就能对minion发送指令了。
minion端：
/etc/salt/pki/minion
[root@openfire2 minion]# ll
total 8
-r-------- 1 root root 1679 May 31 12:57 minion.pem
-rw-r--r-- 1 root root 451 May 31 12:57 minion.pub
master端：
[root@js-93 master]# pwd
/etc/salt/pki/master
[root@js-93 master]# ll
total 28
-r-------- 1 root root 1679 May 31 13:00 master.pem
-rw-r--r-- 1 root root 451 May 31 13:00 master.pub
drwxr-xr-x 2 root root 4096 May 31 13:00 minions
drwxr-xr-x 2 root root 4096 May 31 13:00 minions_autosign
drwxr-xr-x 2 root root 4096 May 31 13:00 minions_denied
drwxr-xr-x 2 root root 4096 May 31 13:05 minions_pre
drwxr-xr-x 2 root root 4096 May 31 13:00 minions_rejected在minion_pre 中有一个等待同意的主机名称
[root@js-93 master]# tree
.
├── master.pem
├── master.pub
├── minions
├── minions_autosign
├── minions_denied
├── minions_pre

和上面的tree 的结果进行对比发现openfire2 在不同的目录下了。
[root@js-93 master]# tree
.
├── master.pem
├── master.pub
├── minions
│ └── openfire2
├── minions_autosign
├── minions_denied
├── minions_pre
└── minions_rejected
发现客户端也有master的public key
[root@openfire2 minion]# ls
minion_master.pub
简单操作：
[root@js-93 master]# salt '*' test.ping
openfire2:
True
[root@js-93 master]# salt '*' cmd.run 'uptime'
openfire2:
13:17:55 up 255 days, 1:29, 1 user, load average: 0.08, 0.07, 0.05
You have mail in /var/spool/mail/root
[root@js-93 master]# salt '*' cmd.run 'df -h'
openfire2:

tmpfs 1.9G 12K 1.9G 1% /dev/shm
/dev/sda1 194M 27M 158M 15% /boot
快速入门：
修改 master端的 /etc/salt/master 文件： #该配置文件里面一定要保持使用空格，如果使用tab键，那么一定会报错。
416 file_roots:
417 base:
418 - /srv/salt
然后查看master端是否有 /srv/salt 这个目录，如果没有则创建。 mkdir /srv/salt
然后重启服务: /etc/init.d/salt-master restart
写一个apache服务的配置：
[root@js-93 salt]# cat apache.sls
apache-install:
pkg.installed:
- names:
- httpd
- httpd-devel
apache-service:
service.running:
- name: httpd
- enable: True #开机启动
- reload: True****一定要注意缩进，该缩进按照2个空格进行缩进，每个层级关系在一起，下一个层级关系则会多增加两个空格。一定不要有别的字符，例如：tab
执行Apache.sls 配置。
master端：
[root@js-93 salt]# salt '*' state.sls apache

grains 的操作实例：
指定系统进行远程命令操作；
[root@js-93 salt]# salt -G os:CentOS cmd.run 'free -m'
openfire2:
total used free shared buffers cached
Mem: 3824 2860 964 0 169 1358
-/+ buffers/cache: 1333 2491
Swap: 2047 0 2047
参数：-G 表示用grains 的数据进行匹配。
grains 可以给minion端赋予 roles角色，然后通过salt 远程执行对应的roles角色就行。
minion端：
[root@openfire2 minion]# cat /etc/salt/grains #这里面的role名称不能用roles 否则会冲突
web: check12
[root@openfire2 minion]# /etc/init.d/salt-minion restart
master端：
[root@js-93 master]# salt -G web:check12 cmd.run 'w'

grains： 在master 的top.sls 里面进行配置minion 的信息，进行执行命令；
master端：
[root@js-93 salt]# cat top.sls
base:

这里的apache 是/src/salt/apache.sls 里面的信息。
[root@js-93 salt]# salt '*' state.highstate #执行这个命令就会有信息返回
Pillar 数据系统
pillar 数据系统默认是关着的（master上面），因此要使用pillar需要修改 master端的 /etc/salt/master 的 552行 "#pillar_opts: False "改成 pillar_opts: True"
[root@js-93 salt]# /etc/init.d/salt-master restart
[root@js-93 salt]# salt '*' pillar.items #就可以查看到很多信息。

Falsepillar 的信息
修改 master端的：/etc/salt/master
#pillar_opts: True 这个再次改成Falsepillar_opts: Falsepillar_roots:
base:
- /srv/pillar
[root@js-93 salt]# mkdir /srv/pillar
[root@js-93 salt]# /etc/init.d/salt-master restart #重启
使用：
先创建一个pillar的一个信息文件：
[root@js-93 salt]# cat /srv/pillar/apache.sls
{% if grains['os'] == 'CentOS' %}
apache: httpd
{% elif grains['os'] == 'Debian' %}
apache: apache2
{% endif %}
然后指定能够读取这个文件的命令或文件：
[root@js-93 salt]# cat /srv/pillar/top.sls
base:
'*':
- apache
查看pillar数据系统的信息：
[root@js-93 salt]# salt '*' pillar.items
openfire2:
----------
apache:
httpd
因为 apache.sls 里面指定的是CentOS的信息才会显示上面的内容，不然不会显示。
[root@js-93 salt]# salt -I 'apache:httpd' test.ping
openfire2:
Minion did not return. [No response]
You have mail in /var/spool/mail/root
[root@js-93 salt]# salt '*' saltutil.refresh_pillar
openfire2:
True
当不能使用的时候，要刷新一下。[root@js-93 salt]# salt -I 'apache:httpd' test.ping
openfire2:
True
Grains 与Pillar的区别
名称 | 存储位置 | 数据类型 | 采集更新方式 | 应用 |
Grains | MInion端 | 静态数据 | minion启动时手机，也可以使用saltutil.sync_grains进行刷新 | 存储Minion基本数据。比如用于匹配Minion，自身数据可以用来做资产管理等 |
Pillar | Master端 | 动态数据 | 在Master端定义，指定给对应的Minion。可以使用saltutil.refresh_pillar刷新 | 存储Master指定的数据，只有指定的Minion可以看到。用于敏感数据保存。 |
远程执行命令详解
远程执行命令三大内容：目标（targeting），模块（Module），返回（Returners）
目标（targeting）
https://docs.saltstack.com/en/latest/topics/targeting/ 所有支持的远程操作命令：主要是看正则表达式；
模块（Module）
https://docs.saltstack.com/en/latest/ref/modules/all/ 官方所有模块配置的地址。
返回（Returners）
https://docs.saltstack.com/en/latest/ref/returners/all/index.html
salt 的访问控制
首先修改/etc/salt/master 的acl控制：
vi /etc/salt/master
245 client_acl:
246 ryan:
247 - test.ping
248 - network.*
修改这里表示，ryan 系统用户只能执行 test.ping 以及network.* 的方法。
别的模块及方法则不行
[ryan@js-93 ~]$ salt '*' test.ping
openfire2:
True
[ryan@js-93 ~]$ salt '*' cmd.run 'w'
Failed to authenticate! This is most likely because this user is not permitted to execute commands, but there is a small possibility that a disk error occurred (check disk/inode usage).
还可以指定某个用户只能访问某类型的机器，或者指定用户不能使用某个方法，以及不能使用某些模块。salt 的信息还可以写入到mysql数据库。这个主要用于二次开发，或者收集记录信息等等，可以在官方文档查看到。
saltstack配置管理
top file 是saltstack的入口文件。
首先修改master端的 /etc/salt/master
file_roots:
base:
- /srv/salt/base
test:
- /srv/salt/test
prod:
- /srv/salt/prod重启：
[root@js-93 salt]# /etc/init.d/salt-master restart
[root@js-93 salt]# mkdir /srv/salt/{base,test,prod}
写入一个批量修改reslov.conf的配置：
[root@js-93 base]# pwd
/srv/salt/base
[root@js-93 base]# cat dns.sls
/etc/resolv.conf:
file.managed:
- source: salt://files/resolv.conf
- user: root
- group: root
- mode: 644
注释 salt:// 这是一个相对路径就相当于：/srv/salt/base的绝对路径一样。
因此，还要在base目录下面创建一个 files目录，用于存放resolv.conf文件；
查看一下需要配置的resolv.conf文件：
[root@js-93 files]# pwd
/srv/salt/base/files
[root@js-93 files]# cat resolv.conf

nameserver 4.4.4.4
nameserver 8.8.8.8
nameserver 114.114.114.114
直接命令行执行：
[root@js-93 base]# salt '*' state.sls dns

案例1：
新系统思想：
1.系统初始化
2.功能模块
3.业务模块
YAML规则语法：
1，缩进；Yaml使用一个固定的缩进放歌表示数据层结构关系。salt需要每个缩进级别有两个空格组成。不要使用tab
2，冒号；每个冒号后面都有一个空格，除了以冒号结尾和路径。
3，短横线；想要表示列表项，使用一个短横杠加一个空格。多个项使用同样的缩进级别作为同一列表的一部分。
jinja 用法：
[root@js-93 base]# cat dns.sls
/etc/resolv.conf:
file.managed:
- source: salt://files/resolv.conf
- user: root
- group: root
- mode: 644

- template: jinja 这里表示一个模板；- defaults:
DNS_SERVER01: 202.96.209.133
DNS_SERVER02: 114.114.114.114
这上面三句话表示变量。files/resolv.conf 这里面表示变量的引用。模板的名称和文件里面的名称一定要一样。系统初始化“模块”
配置resolv.conf 文件：
[root@js-93 init]# cat dns.sls
/etc/resolv.conf:
file.managed:
- source: salt://init/files/resolv.conf
- user: root
- group: root
- mode: 644
设置history的操作时间，操作用户：
[root@js-93 init]# cat history.sls
/etc/profile:
file.append:
- text:
- export HISTTIMEFORMAT="%F %T `whoami`"
把操作命令已日志的方式记录到 /var/log/message 里面；
export PROMPT_COMMAND='{ msg=$(history 1|{ read x y; echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg";}'
写成 sls 文件：
[root@js-93 init]# cat audit.sls
/etc/bashrc:
file.append:
- text:
- export PROMPT_COMMAND='{ msg=$(history 1|{ read x y; echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg";}'
调整内核参数：
[root@js-93 init]# cat sysctl.sls
vm.swappiness: #不使用交换分区
sysctl.present:
- value: 0
net.ipv4.ip_local_port_range: #本地随机端口号范围
sysctl.present:
- value: 10000 65000
fs.file-max: #打开的最大文件数
sysctl.present:
- value: 100000
把上面的所有初始化的内容写入到一个sls文件里面：
[root@js-93 init]# cat env_init.sls
include:
- init.dns
- init.history
- init.audit
- init.sysctl
然后写入 top file文件里面 引用高级状态：
[root@js-93 base]# cat top.sls
base:
'*':
- init.env_init
init.env_init：表示init目录下的 env_init.sls 文件。
执行结果：
salt '*' state.highstate test=True #test=True 测试执行，可以查看到需要更高后的结果，但是，并不会真正的改变内容。
[root@js-93 base]# salt '*' state.highstate test=True

编译安装proxy
状态模块：状态间关系
功 能：条件判断，用于cmd状态模块
常用方法：
onlyif:检查命令，仅当“onlyif”选项指向的命令返回true时才执行name定义的命令
unless：用于检查的命令，仅当“unless”选项指向的命令返回false时才执行name指向的命令。
功能名称：requisites
功 能：处理状态间关系
常用方法：
require #我依赖某个状态
require_in #我被某个状态依赖
watch #我关注某个状态
watch_in #我被某个状态关注
已完成以后的目录结构：
[root@js-93 prod]# tree
.
├── haproxy
│ ├── files
│ │ ├── haproxy-1.6.10.tar.gz
│ │ └── haproxy.init
│ └── install.sls
└── pkg
└── pkg-init.sls
3 directories, 4 files
linux安装一个软件之前，首先要安装这个软件所依赖的软件包。因此，写一个批量安装依赖包的sls
[root@js-93 prod]# cat pkg/pkg-init.sls
pkg-init:
pkg.installed:
- names:
- gcc
- gcc-c++
- glibc
- make
- autoconf
- openssl-devel
安装haproxy：通过saltstack进行远程批量安装，（当然，批量是指，minion端已经和master端进行过认证的服务器）
[root@js-93 prod]# cat haproxy/install.sls
include:
- pkg.pkg-init
haproxy-install:
file.managed:
- name: /usr/local/src/haproxy-1.6.10.tar.gz
- source: salt://haproxy/files/haproxy-1.6.10.tar.gz
- user: root
- group: root
- mode: 755
cmd.run:
- name: cd /usr/local/src && tar zxf haproxy-1.6.10.tar.gz && cd haproxy-1.6.10 && make TARGET=linux26 PREFIX=/usr/local/haproxy && make install PREFIX=/usr/local/haproxy
- unless: test -d /usr/local/haproxy
- require:
- pkg: pkg-init
- file: haproxy-install
haproxy-init:
file.managed:
- name: /etc/init.d/haproxy
- source: salt://haproxy/files/haproxy.init
- user: root
- group: root
- mode: 755
- require:
- cmd: haproxy-install
cmd.run:
- name: chkconfig --add haproxy
- unless: chkconfig --list|grep haproxy
- require:
- file: haproxy-init
net.ipv4.ip_nonlocal_bind:
sysctl.present:
- value: 1
haproxy-config-dir:
file.directory:
- name: /etc/haproxy
- user: root
- group: root
- mode: 755
在 /usr/local/src 下面需要有haproxy的安装包。并且在 files下面有haproxy的启动脚本，会放在/etc/init.d下面。（启动脚本需要修改：BIN=/usr/local/haproxy/sbin/$BASENAME）
执行：salt 'openfire*' state.sls haproxy.install env=prod （这里一定要指定环境，而且，这个执行的过程比较慢，主要是yum安装依赖包，并且编译安装haproxy的配置文件。）
Saltstack配置管理-业务引用haproxy
首先要有一个haproxy.cfg的配置文件：
[root@js-93 prod]# cat cluster/files/haproxy-outside.cfg
global
log 127.0.0.1 local3 notice
maxconn 4096
uid 0
gid 0
daemon
defaults
log global
mode tcp
option tcplog
option dontlognull
retries 3
maxconn 2000
option redispatch
timeout connect 5000
timeout client 50000
timeout server 50000
listen server_haproxy
bind *:8066
balance roundrobin
mode tcp
server server_01 192.168.20.93:8066 weight 3 check
server server_02 192.168.20.172:8066 weight 3 checkhaproxy-outside.cfg
然后写一个haproxy的文件配置管理，与服务管理：
[root@js-93 prod]# cat cluster/haproxy-outside.sls
include:
- haproxy.install #引用上面的安装。
haproxy-service:
file.managed:
- name: /etc/haproxy/haproxy.cfg
- source: salt://cluster/files/haproxy-outside.cfg
- user: root
- group: root
- mode: 644
service.running:
- name: haproxy
- enable: True #加入开机自启动
- reload: True
- require:
- cmd: haproxy-init
- watch: #如果检测到文件被改变，则服务会被重启
- file: haproxy-service
这里的逻辑性比较高，需要结合前面的haproxy 的配置进行解释。
然后到base目录下去编写 top file文件：
[root@js-93 salt]# cat base/top.sls
base:
'*':
- init.env_init
prod:
'openfire*':
- cluster.haproxy-outside
'js-*':
- cluster.haproxy-outside
执行： salt ‘*’ state.highstate
因此：salt下的整体目录结构就是：
[root@js-93 salt]# tree

│ │ ├── dns.sls

添加zabbix agent 用到了pillar 因此，修改了 /etc/salt/master 的配置文件：
pillar_roots:
base:
- /srv/pillar/base
其中：zabbix_agent.sls 的配置如下：
[root@js-93 init]# cat /srv/salt/base/init/zabbix_agent.sls
zabbix-agent-install:
pkg.installed:
- name: zabbix-agent
file.managed:
- name: /etc/zabbix/zabbix_agentd.conf
- source: salt://init/files/zabbix_agentd.conf
- template: jinja
- defaults:
Server: {{ pillar['zabbix-agent']['Zabbix_Server'] }}
- require:
- pkg: zabbix-agent-install
service.running:
- name: zabbix-agent
- enable: True
- watch:
- pkg: zabbix-agent-install
- file: zabbix-agent-installzabbix_agent.sls
然后在环境初始化 env_init.sls 添加zabbix_agent:
[root@js-93 init]# cat env_init.sls
include:
- init.dns
- init.history
- init.audit
- init.sysctl
- init.zabbix_agent
zabbix_agent.conf 的配置内容为：
[root@js-93 init]# cat files/zabbix_agentd.conf |egrep -v "^#|^$"
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server={{ Server }} #注意这一行，这一行是用到了pillar的变量
ServerActive=116.228.90.94
Hostname=hezitwo
UserParameter=mount_disk_discovery,/bin/bash /etc/zabbix/monitor_scripts/mount_disk_discovery.sh mount_disk_discovery
因为现在用了了pillar 修改了pillar的路径：/srv/pillar/base
[root@js-93 base]# cat zabbix.sls
zabbix-agent:
Zabbix_Server: 192.168.20.212
[root@js-93 base]# cat top.sls
base:
'*':
- zabbix
执行: salt '*' state.highstate 即可完成minion端的 zabbix agent的安装；
github 的文档：包含了 nginx memecached pcre 等等。

可以看到 minion端和master端，保持一个长连接的模式。这个模式的好处再于，master处理的信息发送到4505，然后发送到minion端，然后处理后的结果会发送到4506 这个端口。

优化1： 把master 的 /etc/salt/master的 timeout修改成为： timeout: 30（如果是公网的可能会数值调大）
salt-syndic
具体使用方法可查看官当文档：Salt Syndic 这一章节
更换master 的方法：
1.先停止 minion端的 服务，以及master服务。
2.清理 minion端所有key：/etc/salt/pki 下面所有的内容，
3.修改 /etc/salt/minion :master: 192.168.20.93(修改改变的master IP地址。)
4.重启:/etc/init.d/salt-minion start
saltstack 二次开发
grains：
注释：grains 是静态的。获取一次就不会改变。
首先要在 file_roots 下面创建 _grains 的目录；然后写一个编写一个 my grains 的python脚本
[root@js-93 _grains]# pwd
/srv/salt/base/_grains
[root@js-93 _grains]# cat my_grains.py
#!/usr/bin/env python
#coding:utf-8
def my_grains():
'''
My Custin Grains
'''
grains = { 'key1':'val1','key2':'val2'}
return grains
然后执行：salt '*' saltutil.sync_grains 这会把自己写的grians 同步到各个minion上面；
[root@js-93 _grains]# salt '*' saltutil.sync_grains
js-93:
- grains.my_grains
openfire2:
- grains.my_grains
上面这一步会同步到minion端,如下：
[root@openfire2 grains]# ll /var/cache/salt/minion/extmods/grains
total 8
-rw------- 1 root root 157 Jun 2 19:07 my_grains.py
-rw------- 1 root root 382 Jun 2 19:07 my_grains.pyc
[root@openfire2 grains]# cat my_grains.py
#!/usr/bin/env python
#coding:utf-8
def my_grains():
'''
My Custin Grains
'''
grains = { 'key1':'val1','key2':'val2'}
return grains
获取自己写的 grains：
自己写的grains的结果
模块： modules
安装salt 时，自己的模块存放路径为: /usr/lib/python2.6/site-packages/salt/modules
首先要在 file_roots 下面创建一个 _module 目录,然后写一个模块：
[root@js-93 _modules]# pwd
/srv/salt/base/_modules
[root@js-93 _modules]# cat my_disk.py
#!/usr/bin/env python
def list():
cmd = 'df -h'
ret = __salt__['cmd.run'](cmd)
return ret
同步到minion：
[root@js-93 _modules]# salt '*' saltutil.sync_modules
openfire2:
- modules.my_disk
js-93:
- modules.my_disk
minion端查看同步的模块：
[root@openfire2 modules]# pwd
/var/cache/salt/minion/extmods/modules
[root@openfire2 modules]# cat my_disk.py
#!/usr/bin/env python
def list():
cmd = 'df -h'
ret = __salt__['cmd.run'](cmd)
return ret
执行自己写的模块：
[root@js-93 _modules]# salt '*' my_disk.list
js-93:
