如何使用Shell将Nginx虚拟主机（config）文件拆分为较小的文件

问题描述

我有一个nginx服务器，它在一个文件中有大约30多个虚拟主机块。
所有虚拟主机块的运行方式如下：

I have a nginx server and it has around 30+ virtual host block in a single file.All the virtual host block go like that:

    server
       {
    #concrete configuration items
    server_name    myserver.hostname.com;
    #concrete configuration items
    #and so on....

    }

我的问题是如何将每个服务器块分割成一个由server_name值命名的文件？例如，上述服务器块保存到名为myserver.hostname.com.conf
的文件中，我想使用shell代码来完成此任务。

My question is how can I split every server block into a single file named by server_name value? for example the above server block save to a file named myserver.hostname.com.confI would like to use shell code to complete this task.

顺便说一句，我不确定让每个虚拟主机都有其配置文件是否是一个好主意。但是随着虚拟主机的增加，将它们全部粘贴到一个公共文件中变得很麻烦。

By the way, I not sure whether it is a good idea to make every virtual host has its config file.But I did thing as virtual host increasing it became a messy to stuck them all in a common file.

推荐答案

您可以使用 csplit 命令按上下文拆分文件：

You can use csplit command to split file by context:

$ csplit input.conf '/^\s*server\s*$/' {*}

然后 mv （重命名）这些文件为 server_name 来自内容：

Then mv(rename) those files to server_name from content:

$ for i in xx*; do mv $i `grep -oPm1 '(?<=server_name).+(?=;)' $i`; done
