一．项目环境
需要使用Docker 技术在一台主机上创建LNMP服务并运行Wordpress网站平台。然后对此服务使用docker-compose管理工作。
1. 环境描述
| 主机 | 操作系统 | ip地址 | 主要软件 |
|---|---|---|---|
| Docker | CentOS 7.6 x86_64 | 192.168.198.13 | Docker 20.08 |
2.项目需求
（1）使用Docker构建LNMP环境并运行Wordpress网站平台。
（2）为了方便运维和统一管理使用进行docker-compose编排
（3）将所有容器进行快照，然后将Docker镜像打包成tar包备份到本地。
（4）把docker-compose.yml 下载到本地
二．部署过程
1.安装Docker
#关闭防火墙
systemctl stop firewalld.service
setenforce 0
#安装依赖包
yum install -y yum-utils device-mapper-persistent-data lvm2
#设置阿里云镜像源
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#安装 Docker-CE并设置为开机自动启动
yum install -y docker-ce docker-ce-cli containerd.io
systemctl start docker.service
systemctl enable docker.service
2.安装Docker加速器
mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://90b8orj3.mirror.aliyuncs.com"]
}
EOF
systemctl daemon-reload
systemctl restart docker
3.Docker-Compose安装部署
#注意必须是在安装docker的基础上
curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
#下载安装包单独安装DockerCompose
chmod +x /usr/local/bin/docker-compose
#docker-compose添加执行权限
docker-compose --version
#查看docker-compose版本
4.准备依赖文件、配置nginx
#创建项目目录 compose_nginx;
mkdir /opt/compose_nginx/
cd /opt/compose_nginx
mkdir nginx mysql php wwwroot
#上传wordpress软件包
cd /opt/compose_nginx/wwwroot/
ls wordpress-4.9.4-zh_CN.tar.gz
tar xf wordpress-4.9.4-zh_CN.tar.gz
cd /opt/compose_nginx/nginx/
ls wordpress-4.9.4-zh_CN.tar.gz
tar xf wordpress-4.9.4-zh_CN.tar.gz
#上传nginx软件包
cd /opt/compose_nginx/nginx/
ls nginx-1.12.0.tar.gz
nginx-1.12.0.tar.gz
如有nginx的各个文件可直接导入即可
cd /opt/compose_nginx/nginx/
vim Dockerfile
#编写nginx的Dockerfile文件
FROM centos:7
MAINTAINER this is nginx image
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make && useradd -M -s /sbin/nologin nginx

5.配置mysql
#进入mysql子目录
cd /opt/compose_nginx/mysql/
#将mysql包上传到此目录
ls mysql-boost-5.7.20.tar.gz
如有mysql的各个文件可直接导入即可
#编写mysql的Dockerfile文件
cd /opt/compose_nginx/mysql/
vim Dockerfile

7.编写docker-compose.yml
#拉取镜像centos:7
docker pull centos:7
vim docker-compose.yml
version: '2'
services:
nginx:
hostname: nginx
build:
context: ./nginx
dockerfile: Dockerfile
container_name: nginx
ports:
- 80:80
- 443:443
networks:
lnmp:
ipv4_address: 172.18.0.10
volumes:
- ./wwwroot/:/usr/local/nginx/html
mysql:
hostname: mysql
build:
context: ./mysql
dockerfile: Dockerfile
container_name: mysql
ports:
- 3306:3306
networks:
lnmp:
ipv4_address: 172.18.0.20
volumes:
- /usr/local/mysql
php:
hostname: php
build:
context: ./php
dockerfile: Dockerfile
container_name: php
ports:
- 9000:9000
networks:
lnmp:
ipv4_address: 172.18.0.30
volumes_from:
- nginx
- mysql
depends_on:
- nginx
- mysql
links:
- nginx
- mysql
networks:
lnmp:
driver: bridge
ipam:
config:
- subnet: 172.18.0.0/16
docker-compose -f docker-compose.yml up -d
8.验证
#在工作目录，使用docker-compose ps 可以看到启动的容器状态
docker-compose ps
#进入mysql容器，配置用户授权.
[root@test3 compose_nginx]# docker exec -it mysql /bin/bash
[root@mysql mysql-5.7.20]# mysql

三.容器快照，然后将Docker镜像打包成tar包备份到本地
cd /op/
docker save -o 保存目录 导出的镜像
例如：
docker save -o compose_nginx_php.tar compose_nginx_php:latest
四.docker-compose.yml 下载到本地
#sz选择存储路径下载
sz docker-compose.yml
