require_in（我被谁依赖）演示

[root@linux-node1 prod]# vim apache/init.sls

跟require效果差不多

watch 和 watch_in 的使用（不是什么模块都可以使用 service有）

[root@linux-node1 prod]# vim apache/init.sls
看着（watch）修改http.conf 文件的内容就执行重启

[root@linux-node1 prod]# vim apache/init.sls
加了一行 reload: True
看着（watch）修改http.conf 文件的内容就执行重新加载

[root@linux-node1 prod]# vim apache/init.sls
看着（watch in）修改http.conf 文件的内容就执行重新加载

unless用法
[root@linux-node1 ~]# cd /var/www/html/
[root@linux-node1 html]# mkdir admin
[root@linux-node1 admin]# vim index.html
[root@linux-node1 salt]# cd /srv/salt/prod/apache/files/
[root@linux-node1 files]# vim httpd.conf
<Directory /var/www/html/admin>
    AllowOverride All
    Order allow,deny
    Allow from all
    AuthType Basic
    AuthName "welcome"
    AuthUserFile /etc/httpd/conf/htpasswd_file
    Require user admin
</Directory>

[root@linux-node1 files]# whereis htpasswd
htpasswd: /usr/bin/htpasswd /usr/share/man/man1/htpasswd.1.gz
[root@linux-node1 files]# rpm -qf /usr/bin/htpasswd
httpd-tools-2.4.6-88.el7.centos.x86_64

[root@linux-node1 files]# cd ..
[root@linux-node1 apache]# vim init.sls 增加一个
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 # 如果条件为假才执行 htpasswd -bc /etc/httpd/conf/htpasswd_file admin admin

[root@linux-node1 ~]# salt -S '192.168.0.2' state.highstate
http://192.168.0.2/admin

jinja模板用法
[root@linux-node1 ~]# vim /srv/salt/prod/apache/init.sls #加上jinja模板
apache-config:
file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://apache/files/httpd.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
      PORT: 80
      IPADDR: {{ grains['fqdn_ip4'][0] }} #输出的是一个列表

[root@linux-node1 ~]# vim /srv/salt/prod/apache/files/httpd.conf
#Listen 12.34.56.78:80
Listen {{ IPADDR }}:{{ PORT }}

[root@linux-node1 ~]# vim /srv/salt/base/top.sls
#base:
# 'os:ubuntu':
#    - match: grain
#    - web.apache
prod:
'linux-node*.localdomain':
    - lamp
~

[root@linux-node1 ~]# salt '*' state.highstate
