NFS drupal implementation [closed]

问题

I found out NFS is the best way for Multi Server setup in Drupal File sharing

Can someone tell me how this works.

I have two Servers with Drupal Files connected to a common db in third Server

I have one more Server for files how shall I link this too both Drupal Servers using NFS and how NFS works?

when a user uploads the file from first drupal server does it make a copy in Shared Server or makes a

symbolic(soft) link in both drupal servers and adds the file in shared server?

Can someone please tell me and pass me a link to implement NFS for my MultiServer Drupal Setup.

Let us assume Server-A (ip: a.a.a.a) is the server where you are going to save the files, Server-B(ip: b.b.b.b) and Server-C (ip: c.c.c.c) will have drupal. In Server-A you may be storing the files in /store folder. This is to be mounted to folder /mnt/store in Server-B and Server-c.

For this you need to install nfs-kernal-server in Server-A and nfs-common and portmap on all three servers. NFS relies upon Remote Procedure Call(RPC) and portmap service is required to map RPC requests to the correct services.

In Server-A do these configurations:

sudo apt-get install nfs-kernel-server portmap nfs-common
sudo mkdir -p /mnt/nfstest
sudo chmod 777 /mnt/nfstest
sudo mount  --bind /store /mnt/nfstest

sudo vi /etc/default/nfs-kernel-server in this file set NEED_SVCGSSD=no

sudo vi /etc/default/nfs-common in this file set: NEED_IDMAPD=yes and NEED_GSSD=no

sudo vi /etc/idmapd.conf in this file under [Mapping] set Nobody-User = nobody and Nobody-Group = nogroup

sudo vi /etc/hosts.deny add this: portmap mountd nfsd statd lockd rquotad : ALL

sudo vi /etc/hosts.allow add this: portmap mountd nfsd statd lockd rquotad : b.b.b.b, c.c.c.c {ipaddresses}

sudo vi /etc/exports add this: /mnt/nfstest b.b.b.b(rw,sync,no_subtree_check,fsid=0) and /mnt/nfstest c.c.c.c(rw,sync,no_subtree_check,fsid=0)

sudo exportfs -ra
sudo /etc/init.d/portmap restart
sudo /etc/init.d/nfs-kernel-server restart

In Server-B and Server-C do this

sudo apt-get install portmap nfs-common
sudo vi /etc/hosts.deny SET: `portmap : ALL`

sudo vi /etc/hosts.allow SET: portmap : a.a.a.a {Server-A's ipaddress}

sudo vi /etc/default/nfs-common SET: NEED_IDMAPD=yes and NEED_GSSD=no

sudo vi /etc/idmapd.conf under [Mapping] add Nobody-User = nobody and Nobody-Group = nogroup

modprobe nfs
mkdir /mnt/store
sudo mount -t nfs4 a.a.a.a:/ /mnt/store
