docker环境部署在微服务机器上，请不要和应用服务混部。
离线安装docker

cd /wxqyh/soft/micro
tar -xvf docker-19.03.8.tgz
cp docker/* /usr/bin/

复制以下整个脚本执行

chmod +x /etc/systemd/system/docker.service
systemctl daemon-reload

systemctl start docker
systemctl enable docker.service

docker验证

docker version

如果启动失败，请使用以下命令输出错误信息并提交报告

systemctl status docker

常用命令

## 查看当前服务器内得镜像
docker images
## 查看容器（仅包含启动容器） 
docker ps
## 查看容器（包含未启动容器） 
docker ps -a
## 停止一个容器
docker stop 容器id
## 移除一个容器
docker rm 容器id
## 重启一个容器
docker restart 容器id
## 查看docker日志
docker logs 容器id
## 查看docker实时日志
docker logs -f 容器id
## 查看docker尾行实时xxx行日志
docker logs --tail xxx -f 容器id

docker加载基础镜像

3.0.8-3.0.9版本

将微服务相关的物料包拷贝到wxqyh/soft/micro目录下
如果单服务器内需要部署多个相同服务，修改对应的端口号和容器名称即可（不能与现有端口冲突）
微服务部署列表：

cd /wxqyh/soft/micro
docker load < alpine-oraclejdk8_latest.tar
docker load < openjdk_8-jre-alpine.tar

3.1.0版本

将微服务相关的物料包拷贝到wxqyh/soft/micro目录下
如果单服务器内需要部署多个相同服务，修改对应的端口号和容器名称即可（不能与现有端口冲突）
微服务部署列表：

cd /wxqyh/soft/micro
docker load < alpine-oraclejdk8_latest.tar
docker load < openjdk_8-jre-alpine.tar
