一、云服务器docker-compose部署

安装docker环境

安装工具包

yum install yum-utils device-mapper-persistent-data lvm2 -y

Set the Ali mirror source

yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装docker

yum install docker-ce docker-ce-cli containerd.io -y

启动docker

systemctl start docker

# 设为开机启动
systemctl enable docker

设置docker镜像源

vi /etc/docker/daemon.json

{
  "registry-mirrors": [
    "https://register.docker-cn.com/"
  ],
}

Subsequent pull mirrors directly from https://hub.docker.com Website pulls are faster

重启docker

systemctl restart docker

安装mysql镜像测试

docker pull daocloud.io/library/mysql:8.0.20

运行mysql镜像

docker run -d -p 3307:3306 --name mysql -e MYSQL_ROOT_PASSWORD=123456(设置登录密码) be0dbf01a0f3(镜像ID)

进入mysql容器内部

至此mysqlMirror build successfully,下面我们使用docker-compose来管理docker容器,Not installed one by oneMySQL、redis、nginx

安装docker-compose

# 使用国内源安装
curl -L https://get.daocloud.io/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

设置docker-compose执行权限

chmod +x /usr/local/bin/docker-compose

创建软链

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

测试是否安装成功：

$ docker-compose --version

docker-compose version 1.22.0, build f46880fe

编写docker-compose

version: "3.0"

services: 
    # docker容器启动的redis默认是没有redis.conf的配置文件,所以用docker启动redis之前,需要先去官网下载redis.conf的配置文件
    redis: # 服务名称
        container_name: redis # 容器名称
        image: daocloud.io/library/redis:6.0.3-alpine3.11 # 使用官方镜像
        # 配置redis.conf方式启动
        command: redis-server /usr/local/etc/redis/redis.conf --requirepass 123456 --appendonly yes # 设置redis登录密码 123456、--appendonly yes：这个命令是用于开启redis数据持久化
        # Startup without configuration file
        # command: redis-server --requirepass 123456 --appendonly yes # 设置redis登录密码 123456
        ports:
            - 6380:6379 # 本机端口:容器端口
        restart: on-failure # 自动重启
        volumes:
            - ./deploy/redis/db:/data # Mount persistent data to the host
            - ./deploy/redis/conf/redis.conf:/usr/local/etc/redis/redis.conf  # 把redisThe configuration file is mounted to the host
            - ./deploy/redis/logs:/logs # 用来存放日志
        environment:
            - TZ=Asia/Shanghai  # 解决容器 时区的问题
        networks:
            - my-server

    mysql:
        container_name: mysql
        image: daocloud.io/library/mysql:8.0.20 # 使用官方镜像
        ports: 
            - 3307:3306 # 本机端口:容器端口
        restart: on-failure
        environment: 
            - MYSQL_ROOT_PASSWORD=993412 # root用户密码
        volumes:
            - ./deploy/mysql/db:/var/lib/mysql # Used to store database table files
            - ./deploy/mysql/conf/my.cnf:/etc/my.cnf # Store custom configuration files
            # 我们在启动MySQLThe database and tables we need are automatically created when the container is used
            # mysqlAutomatic container startup is provided in the official imagedocker-entrypoint-initdb.dfunction of the script below
            - ./deploy/mysql/init:/docker-entrypoint-initdb.d/ # Stores the initialization script
        networks: 
            - my-server

    server: # egg服务
        container_name: server
        build: # 根据Dockerfile构建镜像
            context: .
            dockerfile: Dockerfile
        ports: 
            - 9000:9000
        restart: on-failure # 设置自动重启,This step must be set,主要是存在mysqlIt starts before it is finishednode服务
        networks: 
            - my-server
        depends_on: # node服务依赖于mysql和redis
            - redis
            - mysql

# Declare the bridge  my-server.
# 重要：Mount all services on the same bridge to communicate with each other through the container name
# 如egg连接mysql和redis,You can communicate with each other through the container name
networks:
    my-server:

nestjs/Dockerfile

FROM daocloud.io/library/node:14.7.0

# 设置时区
ENV TZ=Asia/Shanghai \
    DEBIAN_FRONTEND=noninteractive
RUN ln -fs /usr/share/zoneinfo/${TZ} /etc/localtime && echo ${TZ} > /etc/timezone && dpkg-reconfigure --frontend noninteractive tzdata && rm -rf /var/lib/apt/lists/*

# 创建工作目录
RUN mkdir -p /app

# 指定工作目录
WORKDIR /app

# Copy the current code to /app工作目录
COPY . ./

# npm 源,Use domestic mirror sources to improve download speed
# RUN npm config set registry https://registry.npm.taobao.org/

# npm 安装依赖
RUN npm install 
# 打包
RUN npm run build

# 启动服务
# "start:prod": "cross-env NODE_ENV=production node ./dist/src/main.js",
CMD npm run start:prod

EXPOSE 9000

修改代码

开放云服务器端口

开放端口9000、6380、3307

启动项目

docker-compose -h 查看命令

• docker-compose up 启动服务,Console visible logs
• docker-compose up -d 后台启动服务
• docker-compose build --no-cache Rebuilding the image does not use the cache(最后 docker-compose up -d启动)
• 停止服务 docker-compose down
• 下载镜像过程 docker-compose pull
• 重启服务 docker-compose restart

后台启动服务 docker-compose up -d

测试

二、微信云托管部署

Cloud-hosted pipeline deployment is more convenient

redis服务

Here we deploy on the self-built server used abovedocker搭建的redisservice as a demo

mysql服务

Here we deploy on the self-built server used abovedocker搭建的mysqlservice as a demo

修改代码

Then upload the code to github,Build with cloud-hosted pipelines

新建服务

点击发布后,Cloud hosting will doDockerfile构建流水线,Go to the log to view the build progress

After the WeChat cloud hosting is successfully deployed,Available in the instance list,Click into the container to see the code,The content here cannot be modified,Will be overwritten after the container starts

调试接口

测试redis

三、腾讯云serverless部署

需要注意,The code package of the cloud function cannot exceed500M

模板部署 -- 部署 Nest.js 示例代码

1. 登录 Serverless 应用控制台.
2. Click New App,选择Web 应用>Nest.js 框架,如下图所示：

3. 单击“下一步”,Complete the basic configuration selection

• 上传方式,Select the sample code to deploy directly,单击完成,The deployment of the application can begin.
• 部署完成后,You can find it on the application details page,View basic information about the sample app,并通过 API 网关生成的访问路径 URL 进行访问,查看您部署的 Nest.js 项目

自定义部署nest

初始化您的 Nest.js 项目

npm i -g @nestjs/cli
nest new nest-app

在根目录下,Execute the following command to directly start the service locally.

cd nest-app && npm run start

打开浏览器访问 http://localhost:3000,即可在本地完成 Nest.js 示例项目的访问.

部署上云

Follow the steps below,Simple modifications to an already initialized project,使其可以通过 Web Function 快速部署,The project transformation here is usually divided into the following two steps：

• 新增 scf_bootstrap 启动文件.
• Modify the listening address and port to 0.0.0.0:9000.

1. 修改启动文件 main.ts,监听端口改为 9000:

2. 在项目根目录下新建 scf_bootstrap 启动文件,Add the following to this file（用于启动服务）：

You can also complete this module configuration in the console.

# scf_bootstrap
#!/bin/bash

SERVERLESS=1 /var/lang/node12/bin/node ./dist/main.js

新建完成后,You also need to execute the following command to modify the file executable permission,默认需要 777 或 755 permission to start normally.示例如下：

chmod 777 scf_bootstrap

本地配置完成后,执行启动文件,确保您的服务可以本地正常启动,接下来,登录 Serverless 应用控制台,选择Web 应用>Nest.js 框架,The upload method can choose local upload or code repository pull

注意：The startup file is subject to the files in the project,If already included in your project scf_bootstrap 文件,This content will not be overwritten.

A single function code size 500mb 的上限.在实际操作中,云函数虽然提供了 500mb

关于绕过配额问题：

如果超的不多,那么使用 npm install --production 就能解决问题
