SaltStack的配置管理--jinja
需求场景：使用jinja模板，让各节点的httpd都监听在本机的ip
# vim files/httpd.conf
配置文件修改监听的ip地址和端口以变量的形式
Listen {{ IPADDR }}:{{ PORT }}
# vim init.sls
apache-install:
pkg.installed:
- name: httpd
apache-config:
file.managed:
- name: /etc/httpd/conf/httpd.conf
- source: salt://apache/files/httpd.conf
- user: root
- group: root
- mode: 644
- template: jinja------------------>声明这个是模板
- defaults:------------------------>定义默认的参数和值
PORT: 80------------------------->PORT和IPADDR都为变量
IPADDR: {{ grains['fqdn_ip4'] }}---->通过grains返回数据，此处返回的是一个列表形式，增加指定第一个
apache-auth:
pkg.installed:
- name: httpd-tools
cmd.run:
- name: htpasswd -bc /etc/httpd/conf/htpasswd_file admin admin
- unless: test -f /etc/httpd/conf/htpasswd_file
apache-service:
service.running:
- name: httpd
- enable: True
- reload: True
- watch:
- file: apache-config
# salt -S "192.168.56.11" state.highstate

总结：
1.修改httpd.conf配置
2.修改sls增加：
- template: jinja
- defaults:
PORT: 80
IPADDR: {{ grains['fqdn_ip4'] }}
