架构题：前端有一个 LAMP 架构通过 wordpress 来部署，后端构建一个 NFS 服务器实现要求将用户上传的图片保存至后端 NFS 服务器上。
1.环境准备：
2.一键安装wordpress脚本
准备好源码包如下：
apr-1.7.0.tar.bz2
apr-util-1.6.1.tar.bz2
httpd-2.4.41.tar.gz
mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz
php-7.4.10.tar.xz
wordpress-5.4.2-zh_CN.zip

3.所有服务器上均安装NFS软件
[root@lamp-server ~]#yum install -y nfs-utils;systemctl start nfs-server [root@NFS-client ~]#yum install -y nfs-utils #配置NFS共享文件格式 [root@lamp-server ~]#vi /etc/exports.d/wordpress.exports /apps/httpd/htdocs/wordpress/ *(rw) #重读配置文件，并共享目录 [root@lamp-server ~]#exportfs -r #查看本机所有NFS共享 [root@lamp-server ~]#exportfs -v #查看远程主机 [root@lamp-server ~]#rpcinfo -p 10.0.0.8 program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 44426 status 100024 1 tcp 45345 status 100005 1 udp 20048 mountd 100005 1 tcp 20048 mountd 100005 2 udp 20048 mountd 100005 2 tcp 20048 mountd 100005 3 udp 20048 mountd 100005 3 tcp 20048 mountd 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100227 3 tcp 2049 nfs_acl 100021 1 udp 52521 nlockmgr 100021 3 udp 52521 nlockmgr 100021 4 udp 52521 nlockmgr 100021 1 tcp 37821 nlockmgr 100021 3 tcp 37821 nlockmgr 100021 4 tcp 37821 nlockmgr
4.在NFS-server 上安装自动挂载软件sutofs
[root@NFS-client ~]#yum install -y autofs [root@NFS-client ~]#vi /etc/auto.master /apps/httpd/htdocs/ /etc/auto.wordpress [root@NFS-client ~]#vi /etc/auto.wordpress * -fstype=nfs,vers=3 10.0.0.7:/apps/httpd/htdocs/wordpress/ [root@NFS-client ~]#systemctl restart autofs [root@NFS-client ~]#df -T /apps/httpd/htdocs/wordpress Filesystem Type 1K-blocks Used Available Use% Mounted on 10.0.0.7:/apps/httpd/htdocs/wordpress/ nfs 39518464 4504832 35013632 12% /apps/httpd/htdocs/wordpress #说明共享NFS服务器配置成功
5.上传图片并验证
