    INSTALL NFS SERVER COMPONENTS

$ sudo yum install nfs-utils
START SERVER DAEMONS

$ sudo systemctl enable rpcbind
$ sudo systemctl enable nfs-server
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.
CONFIGURE NFS EXPORTS TO SHARE WITH MULTIPLE NODES


Replace [example.tld], [192.168.xx.xxx], [UID], and [GID] for each entry.
Ensure UID and GID match on NFS server and client!

$ sudo nano /etc/exports
And Add
/var/www/html/vhosts/[example.tld]/wwwroot/pub          [192.168.xx.xxx](rw,insecure,nohide,sync,anonuid=[UID],anongid=[GID],no_subtree_check)        [192.168.xx.xxx](rw,insecure,nohide,sync,anonuid=[UID],anongid=[GID],no_subtree_check)
/var/www/html/vhosts/[example.tld]/wwwroot/var          [192.168.xx.xxx](rw,insecure,nohide,sync,anonuid=[UID],anongid=[GID],no_subtree_check)        [192.168.xx.xxx](rw,insecure,nohide,sync,anonuid=[UID],anongid=[GID],no_subtree_check)
/var/www/html/vhosts/[example.tld]/wwwroot/generated          [192.168.xx.xxx](rw,insecure,nohide,sync,anonuid=[UID],anongid=[GID],no_subtree_check)        [192.168.xx.xxx](rw,insecure,nohide,sync,anonuid=[UID],anongid=[GID],no_subtree_check)
RESTART DAEMON TO LOAD NEW EXPORT CONFIGURATION

$ sudo systemctl restart nfs-server
TEST EXPORTS OUTPUT

$ sudo exportfs
/var/www/html/vhosts/[example.tld]/wwwroot/pub [192.168.xx.xxx]
/var/www/html/vhosts/[example.tld]/wwwroot/var [192.168.xx.xxx]
/var/www/html/vhosts/[example.tld]/wwwroot/generated [192.168.xx.xxx]
REBOOT SERVER TO ENSURE SERVICES START AUTOMATICALLY FOR FUTURE MAINTENANCE

$ sudo reboot
Connection to [hostname.example.tld] closed by remote host.
Connection to [hostname.example.tld] closed.
VERIFY SERVICES AND EXPORTS AGAIN

INSTALL NFS CLIENT COMPONENTS ON EACH CLIENT NODE

$ sudo yum install nfs-utils
CONFIGURE AUTOMATIC NFS MOUNTS FROM NFS-SERVER VIA FSTAB


Replace [example.tld] and [192.168.xx.xxx] for each entry.

$ sudo nano /etc/fstab
Append to bottom of file:
...
[192.168.xx.xxx]:/var/www/html/vhosts/[example.tld]/wwwroot/pub            /var/www/html/vhosts/[example.tld]/wwwroot/pub           nfs     auto,noatime,nolock,bg,nfsvers=4,intr,tcp,actimeo=1800,_netdev 0 0

TEST MOUNTS


It will throw an error if there is a problem

$ sudo mount -a
REBOOT SERVER TO ENSURE MOUNTS ARE ESTABLISHED PROPERLY ON BOOT

$ sudo reboot
Connection to [hostname.example.tld] closed by remote host.
Connection to [hostname.example.tld] closed.
VERIFY MOUNTS AFTER REBOOT ON EACH CLIENT
