Dockerfile:先配置好文件，然后build，镜像-------->容器。
docker-conpose 既可以基于dockerfile,也可以基于镜像，一键式拉起镜像和容器。
docker-compose核心就是yml文件，可以定义容器的一切。通过yml配置，直接运行容器。docker：单节点。docker没有统一对外提供服务的端口和配置。docker一般都是内部访问。无需使用https。
如果要对外以集群和分布式的方式提供统一访问的端口，k8s+ingress.

Docker Compose的解决方案

提供工具用于定义和运行多个docker容器应用；

使用yaml文件来配置应用服务(docker-compse.yml)；

可以通过一个简单的命令docker-compse up可以按照依赖关系启动所有服务；

可以通过一个简单的命令docker-compose down停止所有服务；

当一个服务需要的时候，可以很简单地通过--scale进行扩容;

Compose的特征

更高的可移植性，Docker Compose仅需一个docker-compse up可以完成按照依赖关系启动所有服务，然后使用docker-compose down轻松将其拆解。帮助我们更轻松地部署复杂的应用程序；

单个主机上的多个隔离环境，Compose可以使用项目名称将环境彼此隔离，这带可以在一台计算机上运行同一环境的多个副本，它可以防止不同的项目和服务相互干扰；

Docker Compose配置常用字段:

docker-compose的常用命令：

build:构建服务
ps:列出由docker-compose编排出来的容器
up:创建和启动容器
top:显示容器的进程
logs:查看容器的输出日志
down:删除容器，网络，数据卷。
exec：在容器中执行命令。
stop/start/retart:停止，启动，重启容器。
scale: 指定启动的容器数量

docker-compose编译安装lnmp

安装docker-compose
#下载
curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
#安装
chmod +x /usr/local/bin/docker-compose
#查看版本
docker-compose --version

或者

cd /opt 拖入安装包

mv docker-compose-linux-x86_64 docker-compose
mv docker-compose /usr/local/bin/
chmod 777 /usr/local/bin/docker-compose

[root@localhost opt]# mkdir lnmp
[root@localhost opt]# cd lnmp
