1.编辑文件，添加jinja模块

[root@server1 apache]# cat install.sls 
    install-apache:
      pkg.installed:
        - pkgs:
          - httpd
    
      file.managed:
        - name: /etc/httpd/conf/httpd.conf
        - source: salt://apache/files/httpd.conf
        - template: jinja				##导入jinja模块
        - context:
          port: 80
          host: 172.25.31.2
    
      service.running:
        - name: httpd
        - reload: True
        - watch:
          - file: install-apache
    
    [root@server1 apache]# vim files/httpd.conf 
     42 Listen {
       { host }}:{
       { port}}

2.可以在一个文件中定义变量并且在httpd的配置文件中将变量进行导入，操作如下：

[root@server1 apache]# pwd
    /srv/salt/apache
    [root@server1 apache]# ls
    apache.sls  files  install.sls  lib.sls
    [root@server1 apache]# cat lib.sls 
    {% set host = '172.25.31.2' %}
    [root@server1 apache]# cat install.sls 
    install-apache:
      pkg.installed:
        - pkgs:
          - httpd
    
      file.managed:
        - name: /etc/httpd/conf/httpd.conf
        - source: salt://apache/files/httpd.conf
        - template: jinja
        - context:
          port: 80
    
      service.running:
        - name: httpd
        - reload: True
        - watch:
          - file: install-apache
    [root@server1 apache]# vim files/httpd.conf

jinja结合grains的使用

[root@server1 apache]# vim install.sls 
    [root@server1 apache]# cat install.sls 
    install-apache:
      pkg.installed:
        - pkgs:
          - httpd
    
      file.managed:
        - name: /etc/httpd/conf/httpd.conf
        - source: salt://apache/files/httpd.conf
        - template: jinja
        - context:
          port: 80
          host: {
       { grains['ipv4'][1] }}
    
      service.running:
        - name: httpd
        - reload: True
        - watch:
          - file: install-apache
    [root@server1 apache]# vim files/httpd.conf 
    [root@server1 apache]# salt server2 state.sls apache.install

jinja模版结合pillar

[root@server1 apache]# vim install.sls 
    [root@server1 apache]# cat install.sls 
    install-apache:
      pkg.installed:
        - pkgs:
          - httpd
    
      file.managed:
        - name: /etc/httpd/conf/httpd.conf
        - source: salt://apache/files/httpd.conf
        - template: jinja
        - context:
          port: {
       { pillar['port'] }}		##引入pillar
          host: {
       { pillar['ip'] }}
    
      service.running:
        - name: httpd
        - reload: True
        - watch:
          - file: install-apache

[root@server1 apache]# vim /srv/pillar/web/vars.sls 
    [root@server1 apache]# cat  /srv/pillar/web/vars.sls 
    {% if grains['fqdn'] == 'server2' %}
    webserver: httpd
    ip: 172.25.31.2
    port: 80
    {% elif grains['fqdn'] == 'server3' %}
    webserver: nginx
    ip:172.25.31.3
    port: 80
    {% endif %}

测试：

[root@server1 apache]# salt server2 state.sls apache.install
