Saltstack Automating the deployment of Apache instances

1, configure the Pillar Top.sls:

Base
Nova
-Match:nodegroup
-Nova
Neutron
-Match:nodegroup
-Neutron

2. Configuration of pillar Nova and neutron:

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, configure the state of the TOP.SLS:

Base
‘*‘:
-Apache.start
-Apache.stop

4, Configuration 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:jinjaNote: You must specify, otherwise the pillar variable in the httpd.conf cannot be replaced.
{{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, Configuration 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. Specify in the httpd.conf configuration file:

Listen {{pillar[' Apache '] [' IP ']}}:80

DocumentRoot {{pillar[' Apache ' [' Root ']}}

6. If you do not specify the pillar variable in httpd.conf, specify the custom variable name directly, as follows:

Listen {{addr}}:80

DocumentRoot {{dir}}

7, you can specify defaults or context in Apache.start, as follows:

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
-Context:
Addr: {{pillar[' Apache ' [' IP ']}}
Dir: {{pillar[' Apache ' [' Root ']}}
