环境搭建

AdoptOpenJDK

从https://adoptopenjdk.net/下载AdoptOpenJDK。也可以从清华TUNA镜像下载，根据自己的平台选择下载jdk

• https://mirrors.tuna.tsinghua.edu.cn/AdoptOpenJDK/11/jdk/x64/linux/
• https://mirrors.tuna.tsinghua.edu.cn/AdoptOpenJDK/11/jdk/x64/mac/
• https://mirrors.tuna.tsinghua.edu.cn/AdoptOpenJDK/11/jdk/x64/windows/

下载解压缩后,配置好JAVA_HOME和PATH变量，然后执行java -version查看java版本

jim@debian:~$ java -version
openjdk version "11.0.9.1" 2020-11-04
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9.1+1)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9.1+1, mixed mode)

maven

下载

从https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/下载个maven包。

https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

下载解压后设置MAVEN_HOME环境变量和PATH环境变量中追加$MAVEN_HOME/bin

jim@debian:~$ mvn -version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /usr/local/maven
Java version: 11.0.9.1, vendor: AdoptOpenJDK, runtime: /usr/local/jdk-11.0.9.1_1
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.19.0-13-amd64", arch: "amd64", family: "unix"

配置mirror

修改$MAVEN_HOME/conf/settings.xmlmirrors节点中添加如下内容：

<mirror>
    <id>huaweicloud</id>
    <mirrorOf>*</mirrorOf>
    <url>https://mirrors.huaweicloud.com/repository/maven/</url>
</mirror>

打开$MAVEN_HOME/conf/settings.xml中的localRepository配置

  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->
<localRepository>/usr/local/maven_repo</localRepository>

Eclipse

下载Eclipse

从https://www.eclipse.org/downloads/packages/下载Eclipse IDE for Java Developers

下载lombok

从https://projectlombok.org/download下载lombok.jar

然后执行

java -jar lombok.jar

如果提示Can't find IDE,则需要选择手工选择Eclipse的安装路径(上图的Specify location)，再点击install！

wget https://projectlombok.org/downloads/lombok.jar

echo "-javaagent:$(pwd)/lombok.jar" >> eclipse.ini

配置maven

这一步是统一命令行(shell)中使用mvn和Eclipse中maven使用相同的设置

VSCode

下载VSCode

Visual Studio Code是一个轻量级但功能强大的源代码编辑器，可在您的桌面上运行，并且可用于Windows，macOS和Linux。

https://code.visualstudio.com/

推荐插件

Beautify、Docker、Vetur、markdownlint、ShellCheck

Virtualbox

VirtualBox是功能强大的x86和AMD64 / Intel64虚拟化产品，适用于企业和家庭使用。VirtualBox不仅是面向企业客户的功能极为丰富的高性能产品，而且还是根据GNU通用公共许可证（GPL）版本2的条款可作为开源软件免费提供的唯一专业解决方案。

Vagrant

Vagrant可以理解为针对虚拟机的docker，可以方便拉取别人制作好的虚拟机镜像后启动一个虚拟机实例。

通常可以不用自己安装虚拟机，可以像docker pull一样从Vagrant的app仓库拉取制作好的box（镜像），ubuntu和centos都有官方自己制作的镜像。

Vagrant不仅可以操控virtualbox，还可以操控vmware、libvirt、hyperv等其他虚拟化方案。

install

文档 https://www.vagrantup.com/downloads

mac下安装Vagrant可以通过brew安装

brew cask install vagrant

下载vbox镜像

为本地仓库添加box方法有2种，box是vagrant的镜像。

• 第一种方法是先使用curl或者wget等工具下载镜像，再添加。推荐

## .box文件比较大，也可以下载下来，再调用vagrant box add
wget --tries 100 --continue --output-document debian10.box  https://app.vagrantup.com/debian/boxes/buster64/versions/10.4.0/providers/virtualbox.box

vagrant box add debian10 ./debian10.box

• 第二种方法可以通过vagrant box add 命令后边+box的http地址。

# debian buster64
vagrant box add debian10 https://app.vagrantup.com/debian/boxes/buster64/versions/10.4.0/providers/virtualbox.box

## centos7
vagrant box add centos7 https://mirrors.ustc.edu.cn/centos-cloud/centos/7/vagrant/x86_64/images/CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box

## centos8
vagrant box add centos8 https://mirrors.ustc.edu.cn/centos-cloud/centos/8/vagrant/x86_64/images/CentOS-8-Vagrant-8.3.2011-20201204.2.x86_64.vagrant-virtualbox.box

## ubuntu1804
vagrant box add ubuntu1804 https://mirrors.tuna.tsinghua.edu.cn/ubuntu-cloud-images/bionic/current/bionic-server-cloudimg-amd64-vagrant.box

## ubuntu2004
vagrant box add ubuntu2004 https://mirrors.tuna.tsinghua.edu.cn/ubuntu-cloud-images/server/focal/current/focal-server-cloudimg-amd64-vagrant.box

创建Vagrantfile

Vagrantfile是一个虚拟机实例的配置，比如cpu多少核、内存多大啊

mkdir vmworkspace
cd vmworkspace
vi Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :


Vagrant.configure("2") do |config|
  config.vm.box_check_update = false

  [11,12].each do |i|

      node.vm.provider "virtualbox" do |vb|
        vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
        vb.customize ["modifyvm", :id, "--ioapic", "on"]
        vb.memory = "2048"
        vb.cpus = 2        
      end

      node.vm.box = "ubuntu2004"
      #node.vm.network :forwarded_port, guest: 22, host: "2#{i}22", host_ip: "0.0.0.0", auto_correct:true

      node.vm.provision "shell", inline: <<-SHELL

        if [ $? -ne 0 ]; then
          echo 'swapfile not found. Adding swapfile.'

          echo '/swapfile none swap defaults 0 0' >> /etc/fstab

end

启动

## 启动
vagrant up n11
## ssh登录
vagrant ssh n11
## 关机
vagrant halt n11
## 删除虚拟机
vagrant destroy n11

使用Vagrant的好处是可以快速的重新获取一个全新的既定的vm，比如用下边这条语句

vagrant destroy n11 -f && vagrant up n11 && vagrant ssh n11 

表示强制销毁n11---->重新建立n11---->ssh登录到n11

这样，简单实现了本地开发环境的IaC。

vm-nat网络配置

虚拟机端口映射

在使用vm作为开发测试机的时候首先碰到的问题，就是部署在虚拟机里的服务，比如mysql，怎样在host主机访问呢？

首先整理下概念

• Host：宿主机
• Guest: 虚拟机

这里记录下我的NAT方法

打开VirtualBox中的这台虚拟机-->设置-->网络-->高级-->端口转发

每一行是一个端口映射，主机IP固定写0.0.0.0，子系统IP不用写。主机端口写映射到主机的端口，子系统端口写虚拟机要映射出来的端口。

比如要映射虚拟机的22端口到宿主机，这里由于宿主机的22端口被宿主机的sshd占用了，所以这里不能再用22端口映射，所以改成了28222

这样在宿主机上通过ssh tom@127.0.0.1 -p 28222 这条命令就连到虚拟机的ssh了。

以此类推，其他3306、6379等端口也可以从虚拟机映射到宿主机，如果宿主机已经占用了端口那么就改个未被占用的端口，自行记录对应关系。

docker容器端口映射

以此类推，如果在vm中起docker容器，首先要把容器的端口映射出来。

docker run -d --name mysql57 --restart always -p 3306:3306 mysql:5.7.32

比如这句mysql容器，首先把容器3306端口映射到容器的宿主机(vm)，然后再把vm的3306映射到vm的宿主机。

这样通过两层网络转发，就可以在宿主机直接访问容器的3306数据库了。

安装docker

安装docker主要是为了跑数据库、redis、直接拉起hub.docker.com上的镜像

从系统安装

• Install Docker Engine on Debian
• Install Docker Engine on Centos
• Install Docker Engine on Ubuntu

从二进制安装

• https://docs.docker.com/engine/install/binaries/
• https://download.docker.com/linux/static/stable/x86_64/

开发环境

• 推荐在linux,centos7/8、debian10、ubuntu20.04等linux服务器操作系统上安装docker！
• 不推荐在mac上或windows安装docker-desktop。
• 可以考虑在mac或window上安装一个VirtualBox或VMware来启动一个linux虚拟机，然后在这个linux虚拟机中安装docker。
