课程需要用到的开发环境介绍

2. 开发环境 - 图1

Git-Windows

Git-2.37.1-64-bit.zip

修改下安装路径，一路Next就好，下面代码中的高亮段为二者共用

Git-Linux

yum install git
y
y
git config --global user.name "Jeff"
git config --global user.email "wjajeff@qq.com"
git config --global --list

Docker-Linux

1. 安装Docker

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

2. 设置开机启动Docker

systemctl start docker #启动docker
systemctl enable docker

docker ps -a 
ps -ef|grep docker
systemctl start docker #root用户
ps -ef|grep docker
docker ps -a

3. 配置阿里云镜像

3.1 登录阿里云

3.2 进入控制台

3.3 修改配置文件daemon.json

--Centos
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://47salziq.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

4. 启动

sudo systemctl start docker

5. 测试

sudo docker run hello-world
docker ps -a
docker rm "CONTAINER ID"

[root@localhost ~]# sudo docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
The Docker client contacted the Docker daemon.
The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/

Docker-compose

1. 安装

curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose

[root@localhost ~]# curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   423  100   423    0     0     86      0  0:00:04  0:00:04 --:--:--    91
100 16.2M  100 16.2M    0     0   552k      0  0:00:30  0:00:30 --:--:-- 3565k

2. 测试

docker-compose -v

Mysql

1. 下载镜像

docker pull mysql:5.7
docker images

2. 通过镜像启动

docker run -p 3306:3306 --name mymysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=anwma -d mysql:5.7
-p 3306:3306：将容器的 3306 端口映射到主机的 3306 端口。
-v -v $PWD/conf:/etc/mysql/conf.d：将主机当前目录下的 conf/my.cnf 挂载到容器的 /etc/mysql/my.cnf。
-v $PWD/logs:/logs：将主机当前目录下的 logs 目录挂载到容器的 /logs。
-v $PWD/data:/var/lib/mysql ：将主机当前目录下的data目录挂载到容器的 /var/lib/mysql 。
-e MYSQL_ROOT_PASSWORD=123456：初始化 root 用户的密码。
docker ps -a
# 查看日志
docker logs xxx

3. 进入容器配置

由于mysql的安全策略，现在还不能使用root/123456来访问数据库

3.1 进入容器

通过docker ps -a来查看mysql的容器id然后使用：

[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE         COMMAND                  CREATED         STATUS                     PORTS     NAMES
3a9f972fd40b   hello-world   "/hello"                 6 minutes ago   Exited (0) 6 minutes ago             ecstatic_darwin
1f21d46cc8f6   mysql:5.7     "docker-entrypoint.s…"   8 days ago      Exited (0) 7 days ago                mymysql
221a1edc6490   hello-world   "/hello"                 8 days ago      Exited (0) 8 days ago                exciting_jones

docker exec -it 7dd695806a36 /bin/bash

3.2 进入mysql

mysql -uroot -p123456

3.3 建立用户并授权

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY 'root' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'root' WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit

若之后docker的容器出现STATUS为Exited (0)，只需要使用 docker start “CONTAINER ID”即可 CONTAINER ID可用 docker ps -a查看

Navicat

注册机：NavicatCracker.zip

# 1. 到官网下载电脑对应版本的Navicat
https://www.navicat.com.cn/download/navicat-premium
# 2. 安装好Navicat后,下载注册机文件。patch好安装路径。
# 3. 电脑断网,使用注册机破解即可。

配置

编辑.bashrc文件
**vim ~/.bashrc**

VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export WORKON_HOME=$HOME/.virtualenvs   
source /usr/local/bin/virtualenvwrapper.sh 
#这里不同的linux系统virtualenvwrapper.sh路径可能不一致，最好通过find命令查询一下

退出vim后运行下面命令重新加载

source  ~/.bashrc

虚拟环境使用

1. 新建虚拟环境

mkvirtualenv python_start

2. 查看所有虚拟环境

workon
(python_start) [root@VM-16-17-centos Python-3.8.6]# ls ~/.virtualenvs/
get_env_details  postdeactivate    postrmvirtualenv  premkproject     python_start
initialize       postmkproject     preactivate       premkvirtualenv
postactivate     postmkvirtualenv  predeactivate     prermvirtualenv

3. 进入指定虚拟环境

workon python_start

Go

go的安装和配置

Windows

https://proxy.golang.com.cn,direct

下载直接安装     
官方地址下载安装即可 
go fmt 和goimports保存后自动格式化
settings -> tools -> file watchers

Linux

1. 下载
2. 解压
  tar -xvf go1.15.3.linux-amd64.tar.gz
3. 配置环境变量
  vim ~/.bashrc
    export GOROOT=/root/go
    export GOPATH=/root/projects/go
    export PATH=$PATH:$GOROOT/bin:$GPPATH/bin
4. 编辑保存并退出vim后，记得把这些环境载入：source ~/.bashrc

设置代理加速

go env -w GOPROXY=https://goproxy.io,direct
go env -w GO111MODULE=on
go env #查看环境变量

GoLand的安装

https://www.jetbrains.com/go/download/#section=windows
直接下载安装即可

go imports和go fmt

文件->设置->工具->保存时的操作 or 文件->设置->File Watcher 
看个人喜好自行选择
go fmt 和goimports保存后自动格式化

nodejs的安装和配置

Windows

下载

从官网下下载最新的nodejs，https://nodejs.org/en/download/，根据自身的操作系统选择下载对应版本

:::tips 正常下一步安装即可，记得选择安装路径 :::

npm install -g cnpm --registry=https://registry.npm.taobao.org
npm -v
node -v

Linux

Date: 2022-07-12

1. 下载

wget https://nodejs.org/dist/v16.15.1/node-v16.15.1-linux-x64.tar.xz

2. 解压和建立软连接

tar -xvf node-v16.15.1-linux-x64.tar.xz

3. 建立软连接

一定要先找到node可执行文件的完整路径比如我这里

[root@localhost bin]# pwd
/root/node-v16.15.1-linux-x64/bin

ln -s /root/node-v16.15.1-linux-x64/bin/node /usr/bin/node
ln -s /root/node-v16.15.1-linux-x64/bin/npm /usr/bin/npm

注意ln指令用于创建关联（类似与Windows的快捷方式）必须给全路径，否则可能关联错误。

5. 测试

node -v
[root@localhost bin]# node -v
v16.15.1

6. 安装cnpm

npm install -g cnpm --registry=http://registry.npmmirror.com
[root@localhost bin]# npm install -g cnpm --registry=http://registry.npmmirror.com
