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...

It’s quite interesting. I googled it myself and learned a few things. Posting this, it may be helpful to the original poster.

1,
Found this official tutorial via google "apt-get install lamp-server^"

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

sudo apt-get install lamp-server^

Mind the caret (^) at the end.

2. What does this ^ mean? Why is it pointed out in particular?

I tried it on my machine. I can’t find this thing without adding or replacing *.

Summon google "apt-get install caret" again

Found this

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, Oh, this lamp-server^ turns out to be related to the taskel program.

Google taskel again, 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.

Well, the answer to lz’s question is ready to come out:

lamp-server^ Is this package authoritative?

1, It’s not a package. It’s a task
2. I don’t know what the definition of authority is. Anyway, all software comes from apt-get source.

I won’t go into additional questions. There are too many. Just give me a keyword and google it yourself

nginx mysql php install shell bash

Owner, let me answer some additional questions for you

I remember there is a thing called lnmp, which is linux+nginx+mysql+php, which enables one-click installation of these things. I don’t know if this is what the original poster wants.
There is another thing called PredictionIO, which is written in python. Its installation script vendors.sh automatically installs mongoDB+hadoop. You can also refer to it

Remember that when using fedora, there was an option to install a set of software with a certain function. It feels like it would be the same.
