1.WordPress架构图
LNMP案例之基于Nginx+PHP实现WordPress博客站点,要求Nginx+PHP运⾏在同⼀个Pod的不同容器;nginx主要作用是接入站点请求,如果请求静态资源nginx就直接响应;如果请求的是一个动态php资源,就将对应请求转发给另一个php容器进行处理;在一个pod中运行多容器,网络名称空间是共享的,所以nginx可以将对应请求转发至127.0.0.1:9000这个端口来调用php来处理对应php请求;pod中如果有数据产生,pod通过pvc/pv将对应数据存储到远端存储上;客户端访问通过防火墙,负载均衡器将请求调度到后端node上处理,如果请求所在节点没有运行对应pod,那么对应node会根据路由来转发请求,最终会将请求转发给pod所在节点进行处理;
2、镜像准备
- 准备PHP镜像
- php镜像目录文件
2.1构建php镜像Dockerfile
♾️ bash 代码:root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/php# cat Dockerfile
#PHP Base Image
FROM k8s.lb5.net/baseimages/magedu-centos-base:7.9.2009
RUN yum install -y https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm && yum install php56-php-fpm php56-php-mysql -y
ADD www.conf /opt/remi/php56/root/etc/php-fpm.d/www.conf
#RUN useradd nginx -u 2019
ADD run_php.sh /usr/local/bin/run_php.sh
EXPOSE 9000
CMD ["/usr/local/bin/run_php.sh"]
root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/php#
2.1.2、运行php镜像脚本
♾️ bash 代码:root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/php# cat run_php.sh
#!/bin/bash
#echo "nameserver 10.20.254.254" > /etc/resolv.conf
/opt/remi/php56/root/usr/sbin/php-fpm
#/opt/remi/php56/root/usr/sbin/php-fpm --nodaemonize
tail -f /etc/hosts
root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/php#
2.1.3、构建php镜像脚本
♾️ bash 代码:root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/php# cat build-command.sh
#!/bin/bash
TAG=$1
#docker build -t k8s.lb5.net/magedu/wordpress-php-5.6:${TAG} .
nerdctl build -t k8s.lb5.net/magedu/wordpress-php-5.6:${TAG} .
echo "镜像制作完成,即将上传至Harbor服务器"
sleep 1
nerdctl push k8s.lb5.net/magedu/wordpress-php-5.6:${TAG}
echo "镜像上传完成"
root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/php#
2.1.4、构建php镜像
2.2、准备nginx-wordpress镜像
2.2.1、nginx-wordpress镜像目录文件
2.2.2、构建nginx-wordpress镜像Dockerfile
♾️ bash 代码:root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/nginx# cat Dockerfile
FROM harbor.ik8s.cc/pub-images/nginx-base-wordpress:v1.22.0
ADD nginx.conf /apps/nginx/conf/nginx.conf
ADD run_nginx.sh /apps/nginx/sbin/run_nginx.sh
RUN mkdir -pv /home/nginx/wordpress
RUN chown nginx.nginx /home/nginx/wordpress/ -R
EXPOSE 80 443
CMD ["/apps/nginx/sbin/run_nginx.sh"]
root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/nginx#
该镜像依赖nginx-base-wordpress镜像,在nginx-base-wordpress镜像基础上添加nginx的配置文件,添加运行nginx脚本以及创建存放wordpress代码目录以及更改目录权限等;
2.2.2.1、构建依赖镜像nginx-base-wordpress目录文件
2.2.2.2、构建nginx-base-wordpress镜像Dockerfile
♾️ bash 代码:root@k8s-master01:~/k8s-data/dockerfile/web/pub-images/nginx-base-wordpress# cat Dockerfile
#Nginx Base Image
FROM k8s.lb5.net/baseimages/magedu-centos-base:7.9.2009
RUN yum install -y vim wget tree lrzsz gcc gcc-c++ automake pcre pcre-devel zlib zlib-devel openssl openssl-devel iproute net-tools iotop
ADD nginx-1.22.0.tar.gz /usr/local/src/
RUN cd /usr/local/src/nginx-1.22.0 && ./configure --prefix=/apps/nginx && make && make install && ln -sv /apps/nginx/sbin/nginx /usr/sbin/nginx &&rm -rf /usr/local/src/nginx-1.22.0.tar.gz
root@k8s-master01:~/k8s-data/dockerfile/web/pub-images/nginx-base-wordpress#
该镜像主要做了安装编译环境,放nginx源码包进去编译nginx;
2.2.2.3、构建nginx-base-wordpress镜像脚本
♾️ bash 代码:root@k8s-master01:~/k8s-data/dockerfile/web/pub-images/nginx-base-wordpress# cat build-command.sh
#!/bin/bash
#docker build -t k8s.lb5.net/pub-images/nginx-base-wordpress:v1.20.2 .
#sleep 1
#docker push k8s.lb5.net/pub-images/nginx-base-wordpress:v1.20.2
nerdctl build -t k8s.lb5.net/pub-images/nginx-base-wordpress:v1.22.0 .
nerdctl push k8s.lb5.net/pub-images/nginx-base-wordpress:v1.22.0
root@k8s-master01:~/k8s-data/dockerfile/web/pub-images/nginx-base-wordpress#
2.2.2.4、构建nginx-base-wordpress镜像
2.2.3、运行nginx-wordpress镜像脚本
♾️ bash 代码:root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/nginx# cat run_nginx.sh

#echo "nameserver 10.20.254.254" > /etc/resolv.conf
#chown nginx.nginx /home/nginx/wordpress/ -R
/apps/nginx/sbin/nginx
tail -f /etc/hosts
root@k8s-master01:~/k8s-data/dockerfile/web/magedu/wordpress/nginx#
2.2.4、构建nginx-wordpress镜像脚本

#!/bin/bash
TAG=$1
#docker build -t k8s.lb5.net/magedu/wordpress-nginx:${TAG} .
nerdctl build -t k8s.lb5.net/magedu/wordpress-nginx:${TAG} .
echo "镜像制作完成,即将上传至Harbor服务器"

这里需要注意一点mysql在k8s中是以svc的方式向外提供服务,所以测试我们需要写mysql的svc名称;如果在同一名称空间写mysql svc名称即可,如果跨名称空间需要写mysql svc名称.mysql svc所在名称空间名称,这样coredns才能正常解析mysql svc;
