docker-compose部署一套生产环境

以下是我们公司产品，需要在客户那边搭建起来一套环境，操作系统centos-7.9

需要组件服务

服务首先安装docker，docker-compose

[root@docker-compose ~]# wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@docker-compose ~]# mv docker-ce.repo /etc/yum.repos.d/
[root@docker-compose ~]# yum -y install docker-ce
[root@docker-compose ~]# systemctl start docker-ce && systemctl enable docker
[root@docker-compose ~]# docker -v
Docker version 20.10.16, build aa7e414

配置国内镜像源

[root@docker-compose ~]# vi /etc/docker/daemon.json
{ "registry-mirrors": ["https://cq20bk8v.mirror.aliyuncs.com"] }

2

Docker-compose安装

pip3安装

[root@docker-compose ~]# yum install epel-release
[root@docker-compose ~]# yum install python3-pip 
[root@docker-compose ~]# pip3 install --upgrade pip 
[root@docker-compose ~]# pip3 install docker-compose 

这里会报错：ModuleNotFoundError: No module named 'setuptools_rust'
解决方法：pip3 install -U pip setuptools
 
 
[root@docker-compose ~]# docker-compose --version

二进制安装

从github上下载docker-compose二进制文件安装

• 下载最新版的docker-compose文件

# sudo curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
1

• 若是github访问太慢，可以用daocloud下载

http://get.daocloud.io/

Docker Compose存放在Git Hub，不太稳定。

你可以也通过执行下面的命令，高速安装Docker Compose。

curl -L https://get.daocloud.io/docker/compose/releases/download/v2.5.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose
1

你可以通过修改URL中的版本，可以自定义您的需要的版本。

镜像打成tar包

我这边是从原来服务器上面打包的镜像，没有的需要从新拉取

docker save newmq > 你的储存路径/文件名称.tar

docker save mysql >  /tar/mysql.5.6.tar
docker save redis >  /tar/redis.2.8.tar
docker save elasticsearch  >  /tar/elasticsearch.7.17.2.tar
docker save kibana  >  /tar/kibana.7.17.2.tar
docker save rocketmqinc/rocketmq  >  /tar/rocketmq.tar
docker save nginx   >  /tar/nginx.1.21.6.tar
docker save nacos/nacos-server   >  /tar/nacos.2.0.3.tar

我这边写了个脚本

vim docker-load.sh

hmod +x docker-load.sh

#!/bin/bash
docker load < /tar/elasticsearch.7.17.2.tar
docker load < /tar/kibana.7.17.2.tar
docker load < /tar/mysql.5.6.tar
docker load < /tar/nacos.2.0.3.tar
docker load < /tar/nginx.1.21.6.tar
docker load < /tar/redis.2.8.tar
docker load < /tar/rocketmq.tar

部署mysql服务

我们其实可以把所有组件的yml都放在一起，一起启动，后面再讲

创建目录

mkdir -p /usr/local/docker/mysql5.6
vim docker-compose.yml
1
2

编写yaml文件

version: "3"

services:
  mysql:
    image: mysql:5.6
    restart: always  
    ports:
      - 3306:3306
    environment:
      - MYSQL_ROOT_PASSWORD=Bimuyu2022
    volumes:
      - "/data/container/mysql/data:/var/lib/mysql"
      - "/data/container/mysql/init:/docker-entrypoint-initdb.d"

部署redis服务

创建目录

mkdir -p /usr/local/docker/redis
vim docker-compose.yml
1
2

编写yaml文件

version: "3"

services:
  redis:
    image: redis:2.8
    restart: always
    ports:
      - 6379:6379
    volumes:
      - "/data/container/redis/data:/data"

2

编写yaml文件

version: "3.0"

services:
  elasticsearch:
    image: elasticsearch:7.17.2
    restart: always
    environment:
      - xpack.security.enabled=false
      - discovery.type=single-node
    ports:
      - 9200:9200
    volumes:
      - "./data:/usr/share/elasticsearch/data"
      - "./plugins:/usr/share/elasticsearch/plugins"
      - "./config/jvm.options.d:/usr/share/elasticsearch/config/jvm.options.d"

  kibana:
    image: kibana:7.17.2
    restart: always
    environment:
      - ELASTICSEARCH_HOSTS=http://elasticsearch:9200
    depends_on:
      - elasticsearch

部署RocketMQ服务

创建目录

mkdir -p /usr/local/docker/rocketmq
vim docker-compose.yml
1
2

编写yaml文件

vim下，粘贴带注释代码，会出现代码缩进错位，解决办法：

先设置vim为粘贴模式，即执行:set paste，然后在进入编辑状态，执行粘贴即可。
