wordpress介绍#

1.wordpress简介#

1
WordPress 是一种使用 PHP 语言开发的博客平台，用户可以在支持 PHP 和 MySQL 数据库的服务器上架设自己的网志。也可以把 WordPress 当作一个内容管理系统（CMS）来使用。WordPress 是一个免费的开源项目，在 GNU 通用公共许可证下授权发布

2.wordpress特点#

免费、开源，建站成本低；
WordPress 功能强大、扩展性强。插件众多，易于扩充功能，基本上一个完整网站该有的功能，通过第三方插件都能实现；
WordPress搭建的网站对SEO搜索引擎友好，搜索引擎收录快，网站排名靠前；
备份和网站迁移方便，使用站内工具导出后，使用WordPress Importer插件就能方便地将内容导入新网站；
部署、使用、维护都很简单，方便管理；
有强大的社区支持，有上万的开发者贡献和审查wordpress，所以wordpress更新非常快，也比较安全

本次实践介绍#

1
1.本次实践环境为个人测试学习环境，生产环境请谨慎使用；
2
2.本次实践是在k8s环境中，部署wordpress服务；
3
3.可以成功在在局域网内访问wordpres的web页面。

环境规划#

hostname	IP地址	操作系统版本	k8s版本	角色
k8s-pixiu01	11.0.1.40	centos7.9	v1.24.12	管理节点
k8s-pixiu02	11.0.1.41	centos7.9	v1.24.12	工作节点
k8s-pixiu03	11.0.1.42	centos7.9	v1.24.12	工作节点

环境准备工作#

1.检查k8s环境#
