LAMP实战案例: 在一台服务器上实现 wordpress 应用部署

在一台服务器上实现 wordpress 应用部署

基本任务：本范例是在一台服务器上实现 wordpress 应用部署。目前云ECS主机比较便宜了，对于那些IT爱好者自己建个人博客、论坛等提供很好的契机，LAMP架构是中小企业和个人建站的最经济高效的一个解决方案，利用开源LAMP套包，可以在同一个ECS主机上实现多虚拟主机的应用。

1. 架构及主机

# 一台服务器
Apache（httpd）+PHP (php-fpm模式) + MariaDB
CentOS 8.4
IP: 192.168.250.48/24
10.3.28-MariaDB

2. 安装软件包并配置

[root@CentOS84 ]#cd /data
[root@CentOS84 ]#pwd
/data
[root@CentOS84 ]#
# 下载博客PHP源文件包
[root@CentOS84 ]#wget https://cn.wordpress.org/latest-zh_CN.zip
[root@CentOS84 ]#ll
total 20656
-rw-r--r--  1 root root 21064643 Mar  3 03:00 latest-zh_CN.zip
# 解压后的文件夹名为wordpress
[root@CentOS84 ]#unzip latest-zh_CN.zip

3. 登录网页初始化论坛

3.1 php状态页

3.2 博客wordpress 初始化

浏览器登录 http://192.168.250.48/ 输入前面数据库配置时候的用户名和密&码

运行wordpress 安装程序

经过上面步骤完成了wordpress初始化安装过程，登录wordpress就可以进行管理等个性化配置了

至此整个博客的基本配置全部完成了！
