Step 1:

Install NFS server

Apt-Get install nfs-kernel-Server

Configure the shared directory (about parameters)

Vim/etc/exports

/Opt/html * (RW, sync, no_root_squash)

Start NFS server

/Etc/init. d/Portmap restart

/Etc/init. d/nfs-kernel-server restart

Step 2,

NFS mounting on the client

Mount-t nfs 192.168.1.185:/opt/html/var/www/html

Check whether the mounting is successful

Common Parameters of ubuntu NFS include:
RO read-only access
RW read/write access

Sync all data written for sharing upon request
Async NFS can respond to requests before writing data
Secure NFS is sent through the secure TCP/IP ports below 1024
Insecure NFS is sent over port 1024
Wdelay if multiple users want to write data to the NFS Directory, group write (default)
No_wdelay if multiple users want to write data to the NFS Directory, write the data immediately. When async is used,
This setting is not required.
Hide does not share its subdirectories in the NFS shared directory.
No_hide shares the subdirectory of the NFS Directory
Subtree_check if sub-directories such as/usr/bin are shared, force NFS to check the parent directory
(Default)
No_subtree_check is opposite to the above. The parent directory permission is not checked.
All_squash: The UID and gid of the shared file are mapped to anonymous, an anonymous user.
.
No_all_squash retains the UID and gid of the shared file (default)
All requests of the root user are mapped to the same permissions as those of the anonymous user (
Recognize)
The no_root_squas root user has full management access permissions to the root directory.
Anonuid = xxx specifies the UID of an anonymous user in the NFS server/etc/passwd file
Anongid = xxx specifies the GID of anonymous users in the NFS server/etc/passwd file
