Go的三种安装方式 Go有多种安装方式，你可以选择自己喜欢的。这里我们介绍三种最常见的安装方式： Go源码安装：这是一种标准的软件安装方式。对于经常使用Unix类系统的用户，尤其对于开发者来说，从源码安装可以自己定制。 Go标准包安装
目前创新互联已为近千家的企业提供了网站建设、域名、虚拟空间、网站托管维护、企业网站设计、崆峒网站维护等服务，公司将坚持客户导向、应用为本的策略，正道将秉承"和谐、参与、激情"的文化，与客户和合作伙伴齐心协力一起成长，共同发展。
具体步骤：
1、去官网下载go1.1.2的tarball,一般下载到tem目录
2、打开终端cd /usr/local, tar -zxvf go1.1.2.linux-386.tar.gz
将源码文件解压缩到/usr/local目录，如果解压到其他目录，需要自己设置GOROOT
3、安装gcc工具,因为golang有些功能是使用c写
sudo apt-get install bison gawk gcc libc6-dev make
4、$ cd go/src，$ ./all.bash
运行bash脚本，如果运行正常会获得你的操作系统和cpu信息，自动编译安装
5、将export PATH=$PATH:/usr/local/go/bin 写入$HOME/.profile
最后进行测试输入go version 会显示go1.1.2 linux/386
Go语言在Centos下的安装：
注意，以下命令需要以root身份，或者sudo运行。
说明，如果要自定义安装位置的话，需要配置GOROOT环境变量，所以这里我们采用默认的目录进行安装，就可以不配置GOROOT环境变量了。
首先去官网下载go的安装包，这里用的是：go1.5.1.linux-amd64.tar.gz
■ 1，选择安装路径
由于默认的go路径，在/usr/local下， 所以用如下命令，解压创建/usr/local/go
tar -C /usr/local -xzf go1.5.1.linux-amd64.tar.gz
■ 2，添加PATH环境变量
vi /etc/profile
然后加入下面这行:
export PATH=$PATH:/usr/local/go/bin
■ 3，建立Go的工作空间（workspace，也就是GOPATH环境变量指向的目录）
GO代码必须在工作空间内。工作空间是一个目录，其中包含三个子目录：
src ---- 里面每一个子目录，就是一个包。包内是Go的源码文件
pkg ---- 编译后生成的，包的目标文件
bin ---- 生成的可执行文件。
这里，我们在/home目录下, 建立一个名为gopath(可以不是gopath, 任意名字都可以)的文件夹，
然后再建立三个子文件夹(子文件夹名必须为src、pkg、bin)。如下图：
■ 4，设置GOPATH环境变量
vi /etc/profile
然后加入下面这行:
export GOPATH=/home/gopath
保存后，执行以下命令，使环境变量立即生效:
source /etc/profile
至此，Go语言的环境已经安装完毕。下面开始 HelloWorld
二进制包安装的话：如果安装在了默认位置例如/usr/local/go (Windows系统：c:\Go)这个时候可以不需要设置GOROOT，如果改变了安装的这个默认目录，那么就需要设置GOROOTGOROOT的概念有点Go安装目录的意思GOPATH是一个开发环境目录的意思，下面必须包含bin、pkg、src，然后再src下面新建项目就可以了你在没有设置GOPATH的情况下，也可以把项目建在GOROOT/src下面，其实和GOPATH的概念类似
1、编译vimgdb
下载vimgdb73和vim73
mkdir -p ./tmp
cd tmp
tar zxvf ../vim-7.3.tar.gz
unzip ../vimgdb-for-vim7.3-master.zip
mv vimgdb-for-vim7.3-master vimgdb-for-vim7.3
patch -p0 vimgdb-for-vim7.3/vim73.patch
cd vim73
安装依赖
sudo apt-get install build-essential
sudo apt-get build-dep vim-gtk
sudo apt-get install libncurses5-dev
安装
// 这里直接执行make的操作
make
sudo make install
安装vimgdb runtime
cd ../vimgdb-for-vim7.3
cp vimgdb_runtime ~/.vim/bundle
打开vim
:helptags ~/.vim/bundle/vimgdb_runtime/doc " 生成doc文件
添加配置.vimrc
" vimgdb插件
run macros/gdb_mappings.vim
在vim中执行gdb时，报 “Unable to read from GDB pseudo tty” 的错误，因为没有安装 gdb ,所以安装gdb
sudo apt-get install gdb
2、安装vundle
set up vundle
$ git clone ~/.vim/bundle/vundle
Configure Plugins
在.vimrc文件的开头添加下面的内容，有些不是必须的，可以注掉
set nocompatible " be iMproved, required
filetype off " required
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/vundle/
call vundle#rc()
" alternatively, pass a path where Vundle should install plugins
"let path = '~/some/path/here'
"call vundle#rc(path)
" let Vundle manage Vundle, required
Plugin 'gmarik/vundle'
" The following are examples of different formats supported.
" Keep Plugin commands between here and filetype plugin indent on.
" scripts on GitHub repos
Plugin 'tpope/vim-fugitive'
Plugin 'Lokaltog/vim-easymotion'
Plugin 'tpope/vim-rails.git'
" The sparkup vim script is in a subdirectory of this repo called vim.
" Pass the path to set the runtimepath properly.
Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
" scripts from
Plugin 'L9'
Plugin 'FuzzyFinder'
" scripts not on GitHub
Plugin 'git://git.wincent.com/command-t.git'
" git repos on your local machine (i.e. when working on your own plugin)
Plugin ''
" ...
filetype plugin indent on " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" : PluginList - list configured plugins
" : PluginInstall(!) - install (update) plugins
" : PluginSearch(!) foo - search (or refresh cache first) for foo
" : PluginClean(!) - confirm (or auto-approve) removal of unused plugins
"
" see :h vundle for more details or wiki for FAQ
" NOTE: comments after Plugin commands are not allowed.
" Put your stuff after this line
Install Plugins
Launch vim and run
: PluginInstall
vim +PluginInstall +qall
3、官方vim-lang插件
Config vim file .vimrc,Add content bellow in bottom of the file
" 官方的插件
" Some Linux distributions set filetype in /etc/vimrc.
" Clear filetype flags before changing runtimepath to force Vim to
" reload them.
filetype off
filetype plugin indent off
set runtimepath+=$GOROOT/misc/vim
filetype plugin indent on
syntax on
autocmd FileType go autocmd BufWritePre Fmt
4、代码补全的插件gocode
配置go的环境变量，比如我的配置,GOPATH变量是必须要配置的，PATH中必须把GOPATH的bin也添加进去，否则没有自动提示，会提示找不到模式
export GOROOT=/usr/local/go
export GOPATH=/data/app/gopath
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
Set up gocode
Then you need to get the appropriate version of the gocode, for 6g/8g/5g compiler you can do this:
go get -u github.com/nsf/gocode (-u flag for "update")
Configure vim in .vimrc file
Plugin 'nsf/gocode', {'rtp': 'vim/'}
Install Plugins
Launch vim and run
: PluginInstall
vim +PluginInstall +qall
写一个helloword程序，输入fmt后按C-xC-o如果能看到函数的声明展示出来，说明安装是正确的。
4、代码跳转提示godef
Set up godef
go get -v code.google.com/p/rog-go/exp/cmd/godef
go install -v code.google.com/p/rog-go/exp/cmd/godef
git clone ~/.vim/bundle/vim-godef
Configure vim in .vimrc file
Bundle 'dgryski/vim-godef'
Install Plugins
Launch vim and run
: PluginInstall
vim +PluginInstall +qall
5、代码结构提示gotags
Set up gotags
go get -u github.com/jstemmer/gotags
Put the following configuration in your vimrc:
Bundle 'majutsushi/tagbar'
nmap :TagbarToggle
let g:tagbar_type_go = {
\ 'ctagstype' : 'go',
\ 'kinds' : [
\ 'p:package',
\ 'i:imports:1',
\ 'c:constants',
\ 'v:variables',
\ 't:types',
\ 'n:interfaces',
\ 'w:fields',
\ 'e:embedded',
\ 'm:methods',
\ 'r:constructor',
\ 'f:functions'
\ ],
\ 'sro' : '.',
\ 'kind2scope' : {
\ 't' : 'ctype',
\ 'n' : 'ntype'
\ },
\ 'scope2kind' : {
\ 'ctype' : 't',
\ 'ntype' : 'n'
\ },
\ 'ctagsbin' : 'gotags',
\ 'ctagsargs' : '-sort -silent'
\ }
命令模式下按在右边就会显示当前文件下的函数名，结构体名等等，光标放到相应的tag上，按回车可以快速跳到程序中的相应位置。
再次按会关闭tag窗口。
