四、总结
一、理论
1.LNMP架构
（1）架构
搭建一个lnmp环境，需要涉及到两个目录结构。一个是Dockerfile配置的目录结构，另一个是最终lnmp运行的目录结构。Dockerfile配置目录主要存放Dockerfile构建脚本和一些配置文件，lnmp运行目录主要存放程序运行产生的一些数据，比如mysql数据等。
以下是此次Dockerfile配置的目录结构，包括了nginx、php、mysql的配置文件。
lnmp- nginx- Dockerfile- nginx.conf- sites-enabled- default.conf...- php- Dockerfile- php.ini- php-fpm.conf- www.conf- mysql- Dockerfile- mysqld.cnf
2.背景
（1）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。然后对此服务进行相关的性能调优和管理工作。
（2）所有安装包下载
nginx:
nginx：下载
MySQL:
MySQL ：： MySQL 下载
PHP:
PHP： 下载
（3）任务需求
使用 Docker 构建 LNMP 环境并运行 Wordpress 网站平台
限制 Nginx 容器最多使用 500MB 的内存和 1G 的 Swap
限制 Mysql 容器写 /dev/sda 的速率为 10 MB/s
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
3.Dockerfile部署LNMP
（1）关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
setenforce 0先自定义网络，再使用指定IP运行docker
是LNMP各组件处于同一网段
docker network create --subnet=172.20.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetworkDocker各组件的ip为：
| 容器 | 操作系统 | IP地址 | 主要软件 |
| nginx | CentOS 7 | 172.20.0.10 | Docker-Nginx |
| mysql | CentOS 7 | 172.20.0.20 | Docker-Mysql |
| php | CentOS 7 | 172.20.0.30 | Docker-php |
此实验所需的软件有：
mysql-boost-5.7.20.tar.gz
nginx-1.12.0.tar.gz
php-7.1.10.tar.bz2
wordpress-4.9.4-zh_CN.tar.gz
检测网络：
[root@localhost nginx]# docker network ls

3.构建Nginx镜像
(1) 创建nginx的工作目录
mkdir /opt/nginx
cd /opt/nginx/(2) 上传 nginx-1.12.0.tar.gz、wordpress-4.9.4-zh_CN.tar.gz 到 /opt/nginx/ 目录中
[root@localhost nginx]# rz -E
rz waiting to receive.
[root@localhost nginx]# ls
Dockerfile nginx-1.12.0.tar.gz nginx.conf run.sh wordpress-4.9.4-zh_CN.tar.gz
(3)编辑Dockerfile配置文件
vim DockerfileFROM centos:7
MAINTAINER this is nginx image <lnmp>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make;useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.0.tar.gz /usr/local/src/

ENV PATH /usr/local/nginx/sbin:$PATH
ADD nginx.conf /usr/local/nginx/conf/
ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
VOLUME [ "/usr/local/nginx/html/" ]
CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ](4) 准备Dockerfile文件中所需要的其他配置文件
vim nginx.confworker_processes 1;
events {worker_connections 1024;
}
http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;server {listen 80;server_name localhost;charset utf-8;location / {root html;index index.html index.php;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}location ~ \.php$ {root html;fastcgi_pass 172.20.0.30:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;include fastcgi_params;}}
}(5) 构建nginx镜像
docker build -t nginx:lnmp .
(6) 启动Nginx容器
docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g --net mynetwork --ip 172.20.0.10 nginx:lnmp（7）查看
docker inspect nginx"Networks": {"mynetwork": {"IPAMConfig": {"IPv4Address": "172.20.0.10"

4.如何将运行中的 docker容器保存为 docker 镜像并保存到本地tar包
（1）方法
1、docker commit <容器id> <镜像名>:<tag> ---- 将容器保存成镜像，tag比如说latest保存后 docker images 便可以看到镜像2、docker save -o <tar包名>.tar <镜像名>:<tag> ---- 将镜像保存为.tar文件，默认保存在当前目录
（2）从 tar 包导入docker镜像
1、docker load -i <tar包名>.tar ---- 从 tar 包导入镜像导入镜像后，通过 docker images 便可看到导入的镜像。2、docker run -itd -p <本地端口>:<容器端口> <镜像名>:<tag> ---- 通过镜像起容器
（3）案例「仅保存到tar包」

快速检索PHP配置文件：
egrep -v "^(.)*#(.)*$" nginx.conf | grep -v "^$"egrep -v "^;" php.ini | egrep -v "^$"egrep -v "^;" www.conf | egrep -v "^$"读取容器共享信息：
#表示读取nginx容器的共享信息
