【轉】Centos Linux 使用Yum安裝Go和配置環境

安裝環境：CentOS7.2 64位，安裝Golang

查看go是否安裝過：

$ go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/root/go"
GORACE=""
GOROOT="/usr/lib/golang"
GOTOOLDIR="/usr/lib/golang/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build892156781=/tmp/go-build -gno-record-gcc-switches"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"

查看yum的Golang

查看golang：

$ yum info golang
Loading mirror speeds from cached hostfile Installed Packages Name : golang Arch : x86_64 Version : 1.8.3 Release : 1.el7 Size : 11 M Repo : installed From repo : os Summary : The Go Programming Language URL : http://golang.org/ License : BSD and Public Domain Description : The Go Programming Language. 

如果沒有安裝，執行安裝命令：

yum install golang

這樣安裝之后通過命令行輸入go就可以看到相關的信息。輸入go env查看環境信息：

GOARCH="amd64" GOBIN="" GOEXE="" GOHOSTARCH="amd64" GOHOSTOS="linux" GOOS="linux" GOPATH="/root/go" GORACE="" GOROOT="/usr/lib/golang" GOTOOLDIR="/usr/lib/golang/pkg/tool/linux_amd64" GCCGO="gccgo" CC="gcc" GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build681960794=/tmp/go-build -gno-record-gcc-switches" CXX="g++" CGO_ENABLED="1" PKG_CONFIG="pkg-config" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" 

環境配置

1）查看是否存在.bash_profile, 如果不存在則新建.bash_profile文件

vi /etc/profile

2）添加環境變量 在文件后面追加如下文本：

# GOROOT
export GOROOT=/usr/lib/golang
# GOPATH
export GOPATH=/root/Work/programmer/go/gopath/
# GOPATH bin
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

需要立即生效，在終端執行如下命令：

source /etc/profile

再次查看：

$ go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/root/Work/programmer/go/gopath/"
GORACE=""
GOROOT="/usr/lib/golang"
GOTOOLDIR="/usr/lib/golang/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build963502980=/tmp/go-build -gno-record-gcc-switches"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"

至此，Go語言已經安裝好了。
