今天给各位带来一个出色网站、博客系统 WordPress不过不使用 Docker Hub 提供的 WordPress Docker镜像我们使用 Dockerfile 自己制作实现 LNMP WordPress 运行环境并将 WordPress 部署再其基础之上
为什么不使用 Docker Hub 提供的 WordPress 镜像部署呢
环境准备
Linux 7.5docker v23.0.1docker compose v2.17.0WordPress v6.2 注意这里的环境是博主使用环境不限于此 新手小白教程

进入 wordpress 容器启动 php-fpm、nginx 因为这里使用的 yum 源安装的其他方式也可以没有php-fpm二进制命令启动 php-fpm 服务而使用 systemctl 启动服务需要权限也就是 compose 里面的 privileged: true 字段和 Dockerfile-service 里面的 CMD /usr/sbin/init这样就能保证在容器使用systemctl启动服务了 docker exec -it wordpress bash
systemctl restart php74-php-fpm
systemctl restart nginx浏览器访问 80 端口安装 wordpress 提升
如何把 wordpres 部署到 k8s 中呢
