1. Salt yaml配置文件使用Jinja2模板介紹

jinja2官方網(wǎng)站：?
http://jinja.pocoo.org/

1.1 File狀態(tài)使用template參數(shù)

- template: jinja

1.2 模板文件里面變量使用{{ 名稱 }}

` PORT `

1.3 變量列表

- defaults:
?PORT: 8080

2. 實(shí)戰(zhàn)應(yīng)用

添加監(jiān)聽主機(jī)和端口變量

vim /srv/salt/devfiles/httpd.conf

Listen ` HOST `:` PORT `

# ` MAC `

配置salt master配置文件、pillar配置文件、lamp.sls添加jinja模板：

[root@salt-master112 dev]# egrep -v '^$|^[#]' /etc/salt/master
state_top: top.sls
