saltstack自动部署apache实例
1、配置pillar的top.sls:base:
nova:
- match: nodegroup
- nova
neutron:
- match: nodegroup
- neutron
2、pillar的nova和neutron的配置:
apache:
name: httpd
ip: 172.16.171.120
root: /var/www/neutron
apache:
name: httpd
ip: 172.16.171.110
root: /var/www/nova
3、配置state的top.sls:
base:
'*':
- apache.start
- apache.stop
4、配置apache.start:
apache.start:
pkg.installed:
- name: {{ pillar['apache']['name'] }}
service.running:
- name: {{ pillar['apache']['name'] }}
- watch:
- pkg: {{ pillar['apache']['name'] }}
- file: /etc/httpd/conf/httpd.conf
- user: apache
user.present:
- name: apache
- shell: /sbin/nologin
- home: {{ pillar['apache']['root'] }}
- require:
- group: apache
group.present:
- name: apache
- require:
- pkg: {{ pillar['apache']['name'] }}
file.managed:
- name: /etc/httpd/conf/httpd.conf
- source: salt://apache/httpd.conf
- user: root
- group: root
- mode: 644
- template: jinja 注：必须指定，否则httpd.conf中的pillar变量无法替换。
{{ pillar['apache']['root'] }}/new:
file.directory:
- file_mode: 640
- dir_mode: 750
{{ pillar['apache']['root'] }}/test/process.sh:
file.managed:
- source: salt://apache/process.sh
- makedirs: True
4、配置apache.stop:
apache.stop:
pkg.removed:
- name: {{ pillar['apache']['name'] }}
- require:
- service: {{ pillar['apache']['name'] }}
service.dead:
- name: {{ pillar['apache']['name'] }}
user.absent:
- name: apache
- purge: True
- require:
- pkg: {{ pillar['apache']['name'] }}
5、在httpd.conf配置文件中指定：
Listen {{ pillar['apache']['ip'] }}:80
DocumentRoot {{ pillar['apache']['root'] }}
6、如果在httpd.conf中不指定pillar变量，直接指定自定义变量名，即如下：
Listen ` addr `:80
DocumentRoot ` dir `
7、即可在apache.start指定defaults或context，具体如下：
apache.start:
pkg.installed:
- name: {{ pillar['apache']['name'] }}
service.running:
- name: {{ pillar['apache']['name'] }}
- watch:
- pkg: {{ pillar['apache']['name'] }}
- file: /etc/httpd/conf/httpd.conf
- user: apache
user.present:
- name: apache
- shell: /sbin/nologin
- home: {{ pillar['apache']['root'] }} 或者 {{ salt['pillar']('apache:root','/var/www/html') }}
- require:
- group: apache
group.present:
- name: apache
- require:
- pkg: {{ pillar['apache']['name'] }}
file.managed:
- name: /etc/httpd/conf/httpd.conf
- source: salt://apache/httpd.conf
- user: root
- group: root
- mode: 644
- template: jinja
- context:
addr: {{ pillar['apache']['ip'] }} 或者 {{ salt['pillar']('apache:ip','0.0.0.0') }}
dir: {{ pillar['apache']['root'] }} 或者 {{ salt['pillar']('apache:root','/var/www/html') }}
注：后者可以指定个默认值，当个另minion没定义时，可以使用默认值，而不会出现执行异常。
