ubuntu安装go开发环境

一、为ubuntu20.04更新源

1. 给root用户设置密码：命令：sudo passwd root

2. 备份原来的源，命令：sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

3. 安装vim，命令：sudo apt install vim

4. 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

5. 更新源，命令：sudo apt-get update

6. 如出现依赖问题，解决方式如下：sudo apt-get -f install

7. 更新软件，命令：sudo apt-get upgrade

二、设置允许以root用户登录

1. 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

2. 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)
   

3. 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)
   

4. 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

5. 重启：reboot，选择root用户

三、安装go

1. 创建安装目录，命令：mkdir /home/go

2. 下载go安装包，命令：wget https://golang.google.cn/dl/go1.17.8.linux-amd64.tar.gz

3. 解压go安装包，命令：sudo tar -zxvf go1.17.8.linux-amd64.tar.gz

4. 创建工作目录：命令：mkdir /home/go/goProject

5. 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= P A T H : PATH: PATH:GOROOT/bin

四、安装goland工具

1. 下载golang工具，命令：wget https://download.jetbrains.com.cn/go/goland-2021.3.3.tar.gz
2. 解压，命令：sudo tar -zxvf goland-2021.3.3.tar.gz
3. 重命名为goland，命令：mv GoLand-2021.3.3/ goland
4. 启动goland，命令：/home/go/goland/bin/goland.sh

五、安装ssh并配置允许root登录

1. 安装ssh服务，命令：sudo apt-get install openssh-server
2. 开启ssh的22端口，命令：sudo vim /etc/ssh/sshd_config，将Port注释去掉
   
3. 允许root用户远程登录，命令：sudo vim /etc/ssh/sshd_config，修改成如下
   
4. 重启服务，命令：sudo /etc/init.d/ssh restart
