shell - apt-get install lamp-server^ 是什么个情况

Question

我想，apt-get做为一个包管理器，lamp-server^这个包中包涵了其它包的安装。 那么，我想问的是:lamp-server^这个包权威吗？有没有关于它的详细资料 附加问题， 这否有这样的SHELL文件，执行这个文件就自动部署LAM...

挺有意思的, 自己google下了, 学到一点东西. 贴上来,可能对楼主有所帮助.

1,
通过google "apt-get install lamp-server^" 找到了这个官方教程

https://help.ubuntu.com/community/ApacheMySQLPHP

sudo apt-get install lamp-server^

Mind the caret (^) at the end.

2, 这个 ^ 究竟是什么意思,為什麼还特别指出来?

在自己的机子上试了下, 不加,或换上* 都找不到这个东东.

再次召唤google "apt-get install caret"

找到这个

http://askubuntu.com/questions/211912/whats-the-caret-mean-in-apt-get

Well, the answer is that the caret symbol is a short form for performing a task that otherwise the program “tasksel” would have done with the given package name. tasksel is a program to ease the installation of commonly used things that go together for a particular use.

3, 哦, 这个lamp-server^原来跟taskel这个程序有关.

再次google taskel, https://help.ubuntu.com/community/Tasksel

Tasksel is a Debian/Ubuntu tool that installs multiple related packages as a co-ordinated "task" onto your system.

恩, lz问题的答案就呼之欲出了:

lamp-server^这个包权威吗？

1, 不是包. 是个task
2, 不知权威啥定义. 反正所有的软件都是来自 apt-get源.

附加问题就不说了, 太多了, 给个关键词, 自己google去

nginx mysql php install shell bash

楼主我给你回答下附加问题哈

记得有个东西叫lnmp 就是linux+nginx+mysql+php,实现了这些东西的一键安装，不知道是不是楼主想要的。
还有个东西叫PredictionIO,是python写的，它的安装脚本vendors.sh自动安装了mongoDB+hadoop,也可以参考下

#!/usr/bin/env sh

记得用fedora的时候，有安装某个功能的一组软件的选项，感觉会是同样的道理。
