一下载golang源码包:
现在地址: https://golang.google.cn/dl/
go1.11.2.linux-amd64.tar.gz
二Centos系统版本信息:
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
查看内核版本命令:
[root@localhost ~]# cat /proc/version
inux version 3.10.0-862.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) ) #1 SMP Fri Apr 20 16:44:24 UTC 2018
[root@localhost ~]#
[root@localhost ~]# uname -r
3.10.0-862.el7.x86_64
三安装配置golang语言环境
注意:用root账号安装
1 将下载的二进制包解压至 /opt/app/目录。
依次执行如下命令:
cd /opt
mkdir app
cd app
tar -C /opt/app/ -zxvf go1.11.2.linux-amd64.tar.gz
2 新建GOPATH目录
cd /opt
mkdir goWork
3 将 /opt/app/go/bin 目录添加至PATH环境变量:
在/etc/profile文件尾部添加:
vim /etc/profile
export GOROOT=/opt/app/go
export GOBIN=$GOROOT/bin
export PATH=$PATH:$GOBIN
export GOPATH=/opt/goWork
:wq保存
使其生效:source /etc/profile
4 查看是否配置成功
执行命令:go version
go version go1.11.2 linux/amd64
执行命令:go env
