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...

挺有趣的, 自己google下了, 學到一點東西. 貼上來,可能對樓主有所幫助.

1,
透過google "apt-get install lamp-server^" 找到了這個官方教學

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

sudo apt-get install lamp-server^

Mind the caret (^) at the end.

2, 這個 ^ 究竟是什麼意思,為什麼還特別指出來?

在自己的機子上試了下, 不加,或換上* 都找不到這個東東.

再次召喚google "apt-get install caret"

找到這個

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, 這個lamp-server^原來跟taskel這個程序有關.

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問題的答案就呼之欲出了:

lamp-server^這個包權威嗎？

1, 不是包. 是個task
2, 不知權威啥定義. 反正所有的軟體都是來自 apt-get源.

附加問題就不說了, 太多了, 給個關鍵字, 自己google去

樓主我給你回答下附加問題哈

記得有個東西叫lnmp 就是linux+nginx+mysql+php,實現了這些東西的一鍵安裝，不知道是不是樓主想要的。
還有個東西叫PredictionIO,是python寫的，它的安裝腳本vendors.sh自動安裝了mongoDB+hadoop,也可以參考下

記得用fedora的時候，有安裝某個功能的一組軟體的選項，感覺會是同樣的道理。
