个人公司网站模板怎么做网站设计方案

简介

roles是ansible，playbooks的目录的组织结构，将代码或文件进行模块化，成为roles的文件目录组织结构。  易读，代码可冲哟美好，层次清晰

目录机构

mkdir roles/nginx/{files,handlers,tasks,templates,vars} -ptouch roles/site.yaml roles/nginx/{handlers,tasks,vars}/main.yamlecho 1234 > roles/nginx/files/index.htmlyum -y install nginx && cap /etc/nginx/nginx.conf roles/nginx/templates/nginx.conf.j2

编写任务

vim roles/nginx/tasks/main.yaml---
- name: install epel-release packageyum: name=epel-release state=latest
- name: install nginx packageyum: name=nginx state=latest
- name: copy index.htmlcopy: src=index.html dest=/usr/share/nginx/html/index.html
- name: copy nginx.conf templatetemplate: src=nginx.conf.j2 dest=/etc/nginx/nginx.confnotify: restart nginx
- name: make sure nginx service runningservice: name=nginx state=started enabled=yes

template,相当于copy，会替换原来的

准备配置文件

vim roles/nginx/templates/nginx.conf.j2

编写变量

vim roles/nginx/vars/main.yamlworker_connections: 1024

上面的worker_connections 调用此处的变量

编写处理程序

vim  roles/nginx/handlers/main.yaml---
- name: restart nginxservice: name=nginx state=restarted

编写剧本

vim roles/site.yaml- hosts: sever2roles: - nginx

实施

cd rolesansible-playbook site.yaml --syntax-checkansible-playbook site.yaml
