2019独角兽企业重金招聘Python工程师标准>>> 
1.修改配置文件
取消以下注释
file_roots:
base:
- /srv/salt
2.创建目录
[root@salt-master ~]# mkdir /srv/salt -p
[root@salt-master salt]# mkdir config_file
[root@salt-master config_file]# mkdir script
[root@salt-master script]# tree -L 3 /srv/salt/
/srv/salt/
└── config_file
└── script
└── test.sh
2 directories, 1 fil
[root@salt-master script]# salt 'salt-minion' cmd.script salt://config_file/script/test.sh
执行这个命令就可以在minion端执行这个脚本
3.写sls文件
top.sls
base:
'salt-minion':
- vsftpd
~
vsftpd.sls
/opt/vsftpd:
file.managed:
- source: salt://config_file/vsftpd.conf
- user: root
- group: root
- mode: 600
执行结果
[root@salt-master salt]# salt 'salt-minion' state.highstate#会采用top.sls的方式

grains:
跟puppet的facter功能一样,主要负责采集客户端一些基本信息,也可自定义,可以在客户端自定义,然后自动汇报上来,也可以从服务端定义然后推下去,采集完成在汇报上来pillar跟grains比较的话灵活性更强

grains灵活应用:
对所有是centos系统进行test.ping
[root@salt-master salt]# salt -G 'os:CentOS' test.ping
salt-minion:
True
查询对所有系统cpu是64位的个数
[root@salt-master salt]# salt -G 'cpuarch:x86_64' grains.item num_cpus
salt-minion:
----------
num_cpus:
1
自定义grains:
在minion端的配置文件中加入
grains:
roles:
- webserver
- minion
deployment: datacenter4
cabinet: 12
cab_u: 14-15
在master上就可以收集到相应信息
[root@salt-master salt]# salt 'salt-minion' grains.item roles deployment cabinet cab_u
salt-minion:
----------
cab_u:
14-15
cabinet:
12
deployment:
datacenter4
roles:
- webserver
- minion
states:
salt状态系统的核心是sls,sls表示系统将会是什么样的一种状态,而且是以一种很简单的格式来包含数据,也被叫做配置管理
sls文件实际上只是一些:字典,列表,字符串,数字
yaml:
缩进:salt需要对每个缩进级别是两个空格,但不能使用tabs
键值对采用冒号进行配对,用一个空格隔开key: value
想要表示列表项,使用一个-+空格 - webserver
http://docs.saltstack.com/cn/topics/yaml/index.html
state模块列表
http://docs.saltstack.com/en/latest/ref/states/all/index.html
pillar:
pillar是salt的一个组件,他用于特定的minion定义任何你需要的数据,这些数据可以被salt其它组件使用,pillar解析完成是一个嵌套的dict结构.pillar数据是与特定minion关联的,也就是每一个minion都只能看到自己的数据,所以pillar可以用来传递敏感数据
.
用途:
敏感数据
变量 使用jinja模版,可在文件中使用{{ 变量}} 传递
targetting
定时执行
schedule:
highstate:
funtion: state.highstate
minute: 1
schedule:
sls:
funtion: state.sls
minute: 1
首先打开pillar
pillar_roots:
base:
- /srv/pillar
创建相应目录
mkdir /srv/pillar/nginx
编写top.sls
cd /srv/pillar
必须要有top.sls
[root@salt-master pillar]# vim top.sls
base:
'salt-minion':
- nginx.nginx
编写nginx.sls
[root@salt-master pillar]# vim nginx/nginx.sls
schedule:
nginx:
function: state.sls
minutes: 1
args:
- 'nginx'
[root@salt-master pillar]# salt 'salt-minion' pillar.data
salt-minion:
----------
schedule:
----------
nginx:
----------
args:
- nginx
function:
state.sls
minutes:
1
修改配置文件
[root@salt-master pillar]# vim ../salt/config_file/nginx/conf.d/default.conf
[root@salt-master pillar]# salt 'salt-minion' saltutil.refresh_pillar
salt-minion:
True
[root@salt-master pillar]# salt 'salt-minion' cmd.run 'netstat -anutlp|grep nginx'
salt-minion:
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 6535/nginx
tcp 0 0 0.0.0.0:8088 0.0.0.0:* LISTEN 6535/nginx
等待一分钟
以上需要注意的是具体应用的sls需要和实际命令一致
例如:
salt 'salt-minion' state.sls sls_file.nginx
schedule:
nginx:
function: state.sls
minutes: 1
args:
- 'nginx'
就应该为以下内容
schedule:
nginx:
function: state.sls
minutes: 1
args:
- 'sls_file.nginx'
top.sls为一个路由文件
base:
'salt-minion':
- nginx.nginx
补充:
例如:
nginx:
pkg:
- installed
service:
- running
- enable: True
- reload: True
- watch:
- pkg: nginx
- file: /etc/nginx/nginx.conf
- file: /etc/nginx/conf.d/default.conf
/etc/nginx/nginx.conf:
file.managed:
- source: salt://config_file/nginx/nginx.conf
- user: root
- group: root
- mode: 644
/etc/nginx/conf.d/default.conf:
file.managed:
- source: salt://config_file/nginx/conf.d/default.conf
- user: root
- group: root
- mode: 644
- template:jinja
- defaults:# - context:
port: 8080
在salt://config_file/nginx/conf.d/default.conf这个文件中
Listen {{ port }}
这样就可以在模版以变量的方式传递进去
也可以用控制
- context:
{% if grains['id'] == 'salt-minion-01' %}
port: 8080
{% elif grains['id'] == 'salt-minion-02' %}
port 8081
{% else %}
port: 8082
{% endif %}
另外还可以采用这种方式
pillar
nginx:
{% if grains['id'] == 'salt-minion-01' %}
port: 8080
{% elif grains['id'] == 'salt-minion-02' %}
port 8081
{% else %}
port: 8082
{% endif %}
salt '*' saltutil.refresh.pillar
salt '*' pillar.get nginx:port
- context:
port: {{ salt['pillar.get']('nginx:port', 80)}}
#port: pillar['nginx']['port']
