go lang -- 安装

我的环境时 thinkpad s430, ubuntu 16.04, 64位 得益于论坛里各位前辈的指点, 现将安装流程记录如下方便大家方便自己 ## 软件需求 需要gcc, make, git 等一些常用的开发软件 ```shell apt-get install bison ed gawk gcc libc6-dev make git ``` ## 环境变量 可以在/etc/profile, ~/.bashrc中添加go使用的环境变量 ```bash export GOROOT=/usr/local/go export GOPATH=$HOME/project/go export GOBIN=$HOME/bin export GOROOT_BOOTSTRAP=/usr/local/go1.4 export PATH=$PATH:$GOROOT/bin:$GOBIN ``` ## 拉取源码 ```shell git clone https://github.com/golang/go.git ``` ## 准备编译工具 1.4 以后的go 使用go 构建自己的编译工具(boot_strap), 且为必要条件,所以我们用1.4的版本先行编译go,再用该go编译最新的源码 ```shell git fetch origin release-branch.go1.4:release-branch.go1.4 git checkout release-branch.go1.4 cd src ; ./make.bash mv /root/bin/go /usr/local/go1.4/bin/ ``` 为什么有最后一步的mv操作? - 查看make.bash就不难查到,它的编译环境已经限死在/usr/local/go1.4/bin/ ## 开始编译最新的版本吧 我们需要切到最新的发布版本分支上,编译我们需要的版本(此时go最新的分支为1.9) ```shell git fetch origin release-branch.go1.9:release-branch.go1.9 git checkout release-branch.go1.9 cd src ; ./make.bash ``` ## 完整的操作shell ```shell $ su root $ apt-get install gcc vim make git $ echo "export GOROOT=/usr/local/go" >> /etc/profile $ echo "export GOPATH=$HOME/project/go" >> /etc/profile $ echo "export GOBIN=$HOME/bin" >> /etc/profile $ echo "export GOROOT_BOOTSTRAP=/usr/local/go1.4" >> /etc/profile $ echo "export PATH=$PATH:$GOROOT/bin:$GOBIN" >> /etc/profile $ source /etc/profile $ cd /usr/local/ $ git clone https://github.com/golang/go.git $ cp go go1.4 -rf $ cd go1.4 $ git fetch origin release-branch.go1.4:release-branch.go1.4 $ git checkout release-branch.go1.4 $ cd src ; ./make.bash $ mv /root/bin/go /usr/local/go1.4/bin/ $ cd /usr/local/go $ git fetch origin release-branch.go1.9:release-branch.go1.9 $ git checkout release-branch.go1.9 $ cd src ; ./make.bash $ go version ``` 看到以下输出时,恭喜你! ```shell go version go1.9.5 linux/amd64 ```
