【Dockerfile镜像实战】构建LNMP环境并运行Wordpress网站平台
一、项目背景和要求
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
二、项目环境
主机 操作系统 IP地址 主要软件 宿主机 CentOS 7.3 x86_64 192.168.2.106 Docker 19.03 Nginx容器 172.18.0.10 Mysql容器 172.18.0.20 PHP容器 172.18.0.30 三、部署过程
1）创建自定义网络
#关闭防火墙和selinux systemctl stop firewalld systemctl disable firewalld setenforce 0- 1
- 2
- 3
- 4
#创建自定义网络 docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork- 1
- 2
2）部署Nginx
容器IP：172.18.0.10
Step1 创建工作目录并上传相关软件包
mkdir /opt/nginx cd /opt/nginx- 1
- 2
mkdir /opt/nginx/html tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html- 1
- 2
Step2 编写Dockerfile文件
vim Dockerfile FROM centos:7 MAINTAINER this is nginx image <wl> RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make RUN useradd -M -s /sbin/nologin nginx ADD nginx-1.24.0.tar.gz /usr/local/src/ WORKDIR /usr/local/src/nginx-1.24.0 RUN ./configure \ --prefix=/usr/local/nginx \ --user=nginx \ --group=nginx \ --with-http_stub_status_module && make && make install 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 EXPOSE 443 ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]- 1

Step4 创建nginx镜像
docker build -t nginx:lnmp .- 1
Step5 运行容器
#以nginx容器 在后台运行镜像 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。- 1
