1. 当前需求
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. 前置准备
主机 | 操作系统 | IP 地址 | 主要软件 |
|---|---|---|---|
宿主机 | CentOS 7.3 x86_64 | 192.168.67.100 | Docker 19.03 |
Nginx 容器 | 172.18.0.10 | ||
Mysql 容器 | 172.18.0.20 | ||
PHP 容器 | 172.18.0.30 |

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
#创建自定义网络

docker run -d --name nginx -p 80:80 -v /opt/nginx/html:/usr/local/nginx/html --net mynetwork --ip 172.18.0.10 nginx:lnmp
- "-d" 表示以后台运行的方式启动容器。
- "--name nginx" 设置容器的名称为 "nginx"。
- "-p 80:80" 将主机的 80 端口映射到容器的 80 端口，使得可以通过主机的 IP 地址访问 NGINX 服务器。
- "-v /opt/nginx/html:/usr/local/nginx/html" 将主机上的 /opt/nginx/html 目录与容器内的 /usr/local/nginx/html 目录进行挂载，实现文件共享。
- "--net mynetwork --ip 172.18.0.10" 将容器连接到名为 "mynetwork" 的用户自定义网络，并指定容器的 IP 地址为 172.18.0.10。
- "nginx:lnmp" 指定了要使用的 NGINX 服务器镜像和标签。
