ubuntu安装go开发环境

一、为ubuntu20.04更新源 给root用户设置密码：命令：sudo passwd root备份原来的源，命令：sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak安装vim，命令：sudo apt install vim修改/etc/apt/sources.list文件，命令：sudo vim /etc/apt/sources.list，将里面的内容全删后，配置为清华源，清华源如下：

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

更新源，命令：sudo apt-get update如出现依赖问题，解决方式如下：sudo apt-get -f install更新软件，命令：sudo apt-get upgrade 二、设置允许以root用户登录 执行命令：sudo vim /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf， 把配置改为如下所示

[Seat:*]
user-session=ubuntu
greeter-show-manual-login= true
all-guest=false #这个可以 不用配置

执行sudo vim /etc/pam.d/gdm-autologin注释掉auth required pam_succeed_if.so user != root quiet_success这一行(第三行左右)

执行sudo vim /etc/pam.d/gdm-password注释掉 auth required pam_succeed_if.so user != root quiet_success这一行(第三行左右)

执行sudo vim /root/.profile修改配置文件如下

# ~/.profile: executed by Bourne-compatible login shells.

if [ "$BASH" ]; then
 if [ -f ~/.bashrc ]; then
  . ~/.bashrc
 fi
fi
tty -s && mesg n || true
mesg n || true

重启：reboot，选择root用户 三、安装go 创建安装目录，命令：mkdir /home/go下载go安装包，命令：wget https://golang.google.cn/dl/go1.17.8.linux-amd64.tar.gz解压go安装包，命令：sudo tar -zxvf go1.17.8.linux-amd64.tar.gz创建工作目录：命令：mkdir /home/go/goProject配置环境变量，命令：sudo vim /etc/profile

export GOROOT=/home/go/go
export GOPATH=/home/go/goProject
export GOPROXY=https://goproxy.cn
export PATH=$PATH:$GOROOT/bin

四、安装goland工具 下载golang工具，命令：wget https://download.jetbrains.com.cn/go/goland-2021.3.3.tar.gz解压，命令：sudo tar -zxvf goland-2021.3.3.tar.gz重命名为goland，命令：mv GoLand-2021.3.3/ goland启动goland，命令：/home/go/goland/bin/goland.sh 五、安装ssh并配置允许root登录 安装ssh服务，命令：sudo apt-get install openssh-server开启ssh的22端口，命令：sudo vim /etc/ssh/sshd_config，将Port注释去掉
允许root用户远程登录，命令：sudo vim /etc/ssh/sshd_config，修改成如下
重启服务，命令：sudo /etc/init.d/ssh restart
