第一步：写一篇博客后（插入图片）查看文件位置
[[email?protected] ~]# cd /application/nginx/html/blog/
[[email?protected] blog]# tree wp-content/uploads/
wp-content/uploads/
└── 2019
└── 09
├── 345274240345244247344273231-100x100.jpg
├── 345274240345244247344273231-150x150.jpg
├── 345274240345244247344273231-300x298.jpg
├── 345274240345244247344273231.jpg
├── 345274240347242247346231250-100x100.png
├── 345274240347242247346231250-147x150.png
└── 345274240347242247346231250.png
2 directories,7 files

第二步：移动文件至临时目录

[[email?protected] uploads]# mv 2019 /tmp/

第三步：将blog的资源迁移到nfs（即第一步的信息放进nfs服务器里）
资源目录为：wp-content/uploads/

第四步：建立uid相同的用户（两台服务器的uid相同）

[[email?protected] blog]# id www
uid=501(www) gid=501(www) groups=501(www)

[[email?protected] ~]# useradd -u 501 www
[[email?protected] ~]# id www
uid=501(www) gid=501(www) groups=501(www)
修改变量

[[email?protected] ~]# vim /etc/exports
/data 172.16.1.0/24(rw,sync,no_all_squash,anonuid=501,anongid=501)
重启

/etc/init.d/nfs reload

第五步：
显示输出目录列表

showmount -e

[[email?protected] blog]# showmount -e 172.16.1.31
Export list for 172.16.1.31:
/data 172.16.1.0/24

同步操作31主机创建07需挂载的目录，并授权

[[email?protected] ~]# mkdir /data/nfs-blog
[[email?protected] ~]# chown -R www.www /data

第六步：挂载前查看文件，备份
[[email?protected] blog]# cd wp-content/uploads/
[[email?protected] uploads]# ll
total 4
drwxr-xr-x 3 www www 4096 Sep 11 21:34 2019 （这里2019为创建的文件夹名称，可以这么理解）
[[email?protected] uploads]# mv 2019 /tmp/
[[email?protected] uploads]# ll
total 0
[[email?protected] uploads]# cd ../

第七步：挂载到31的目录下
[[email?protected] wp-content]# mount -t nfs 172.16.1.31:/data/nfs-blog /appliication/nginx/html/blog/wp-content/uploads/
df -h 查看信息
[[email?protected] wp-content]# which mount
/bin/mount
第八步：挂载目录放入开机自启动
[[email?protected] wp-content]# vi /etc/rc.local
mount -t nfs 172.16.1.31:/data/nfs-blog /application/nginx/html/blog/wp-content/uploads/
查看资源目录内容：无信息
[[email?protected] wp-content]# ls /application/nginx/html/blog/wp-content/uploads/
博客页面照片不能显示

第九步：把文件复制到当前目录后刷新博客，可以重新看见图片
[[email?protected] uploads]# cp -a /tmp/2019/ ./

查看图片位置
[[email?protected] ~]# ls /data/nfs-blog/2019/
09
[[email?protected] ~]# ls /data/nfs-blog/2019/09/张大仙-100x100.jpg 张大仙.jpg 张碧晨.png张大仙-150x150.jpg 张碧晨-100x100.png张大仙-300x298.jpg 张碧晨-147x150.png
