1.1 构建目录结构
此操作是安装nginx+mysql+tomcat+db的目录结构,可以参考一下,不错~
1
|
mkdir -p /ansible/roles/ {nginx,mysql,tomcat,db}/{defaults,files,handlers,meta,tasks,templates,vars}
|
- defaults 默认寻找路径
- tasks 存放playbooks路径
- files 存放文件和脚本包,copy模块文件搜索路径
- templates 模版存放路径
- handlers notify调用部分playbook存放路径
- vars roles内变量存放路径

- hosts: bgo ####这个是hosts定义个主机组名字,如果是单台主机可以直接写地址
remote_user: root ####执行用户
roles: #####解释配置文件目录,因为我们这次装的是tomcat所以注释其他的

# - mysql
- tomcat
