Article Title: NFS configuration and deployment in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

NFS is a good shared storage system, but its performance is not very good under high load.

10.0.0.1-NFS Server

10.0.0.2-NFS Client

On NFS Server:

Shared Directory:/nfspool

NFS running user: nfsnobody

# Mkdir/nfspool

# Vi/etc/exports

/Nfspool 10.0.0.2 (rw, async, anonuid = 65534, anongid = 65534)

# Mkdir-p/nfspool

# Chown nfsnobody: nfsnobody/nfspool

# Chown-R nfsnobody: nfsnobody/nfspool /.

# Service portmap start

# Service nfslock start

# Service nfs start

On the NFS Client:

Remote NFS shared directory mount point:/usr/local/nfs

# Service portmap start

# Mkdir/usr/local/nfs

# Chown nfsnobody: nfsnobody/usr/local/nfs

# Chmod 777/usr/local/nfs

# Mount-t nfs-o soft, intr, bg, timeo = 50 10.0.0.1:/nfspool/usr/local/nfs

# Vi/etc/fstab

10.0.0.1:/nfspool/usr/local/nfs soft, intr, bg, timeo = 50 0 0

Note:

1. exports parameter description
