saltstack通过state安装nginx

创建nginx.sls文件

install_nginx是安装Nginx的配置，nginx_running负责进程管理，nginx_conf下发Nginx主配置的模板文件，vhost_conf下发Vhost的配置文件。

[root@29-server]# cat /srv/salt/nginx.sls 
{% set confdir="/etc/nginx/" %}
{% if grains['num_cpus'] > 2 %}
install_nginx:
  pkg.installed:
    - name: nginx

nginx_running:
  service.running:
    - name: nginx
    - enable: Ture
    - require:
      - pkg: install_nginx
    - watch:
      - file: nginx_conf
      - file: vhost_conf

nginx_conf:
  file.managed:
    - name: {{confdir}}nginx.conf
    - source: salt://nginx.j2
    - user: root
    - group: root
    - template: jinja
    - mode: 644

vhost_conf:
  file.managed:
    - name: {{confdir}}conf.d/nginx.conf
    - source: salt://test_vhost.conf
    - user: root
    - group: root
    - mode: 644
{%endif%}

nginx主配置文件内容

vhost配置文件内容

[root@29-server]# cat test_vhost.conf 
server {

    location / {

        }
    }

执行状态模块命令

这是第二次执行显示的信息，第一次执行显示信息太多，就不放在这里了。
