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

[root@linux-node1 apache]# 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 }}[root@linux-node1 apache]# vim init.sls apache-install:  pkg.installed:    - name: httpdapache-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'][0] }}---->通过grains返回数据，此处返回的是一个列表形式，增加[0]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_fileapache-service:  service.running:    - name: httpd    - enable: True    - reload: True    - watch:      - file: apache-config[root@linux-node1 apache]# salt -S "192.168.56.11" state.highstate----------          ID: apache-config    Function: file.managed        Name: /etc/httpd/conf/httpd.conf      Result: True     Comment: File /etc/httpd/conf/httpd.conf updated     Started: 11:14:08.537957    Duration: 25.518 ms     Changes:                 ----------              diff:                  ---                   +++                   @@ -42,7 +42,7 @@                   # prevent Apache from glomming onto all bound IP addresses.                   #                   #Listen 12.34.56.78:80                  -Listen 80                  +Listen 192.168.56.11:80---->更改为监听本机ip地址，端口为80                   #                   # Dynamic Shared Object (DSO) Support[root@linux-node1 apache]# netstat -tulnp|grep httpdtcp        0      0 192.168.56.11:80        0.0.0.0:*               LISTEN      6837/httpd          [root@linux-node1 apache]# vim /srv/salt/base/top.sls prod:  'linux-node*.example.com':    - lamp[root@linux-node1 apache]# salt '*' state.highstate[root@linux-node2 ~]# netstat -tulnp |grep httpdtcp        0      0 192.168.56.12:80        0.0.0.0:*               LISTEN      16447/httpd         总结：1.修改httpd.conf配置2.修改sls增加：- template: jinja  - defaults:    PORT: 80    IPADDR: {
   { grains['fqdn_ip4'][0] }}
