一．项目环境
公司在实际的生产环境中，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
kdir 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
cd /opt/compose_nginx/nginx/
vim Dockerfile
#编写nginx的Dockerfile文件

MAINTAINER this is nginx image <wl>
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
#编写mysql的Dockerfile文件
cd /opt/compose_nginx/mysql/
vim Dockerfile
FROM centos:7
MAINTAINER this is mysql image <wl>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
ADD mysql-boost-5.7.20.tar.gz /usr/local/src/

vim my.cnf

6.配置php
cd /opt/compose_nginx/php/
#将php包上传
ls php-7.1.10.tar.bz2
cd /opt/compose_nginx/php/
vim Dockerfile
FROM centos:7
MAINTAINER this is php image <wl>
RUN yum -y install gd \

ENV PATH /usr/local/php/bin:/usr/local/php/sbin:$PATH
ADD php.ini /usr/local/php/lib/
ADD php-fpm.conf /usr/local/php/etc/
ADD www.conf /usr/local/php/etc/php-fpm.d/
EXPOSE 9000
ENTRYPOINT [ "/usr/local/php/sbin/php-fpm", "-F" ]
#准备php-fpm.conf php.ini、www.conf 配置文件
vim php.ini
#该配置文件模板位于安装目录的 php-7.1.10/php.ini-development 位置
#939行,取消注释，修改
date.timezone = Asia/Shanghai
#1170行,修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
vim php-fpm.conf
#该配置文件位于 /usr/local/php/etc/php-fpm.conf.default
#17行，删除注释符号“;”
pid = run/php-fpm.pid
vim www.conf
#该配置文件位于 cd /usr/local/php/etc/php-fpm.d/
user = nginx
group = nginx
#36行，修改监听IP和端口为容器IP:9000端口
listen = 172.18.0.30:9000
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

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
