Detailed steps for mounting NFS to other machines in CentOS

Detailed steps for mounting NFS to other machines in CentOS

Function to be implemented: Mount/share on 10.1.1.36 to/share on 10.0.1.31.

1. premise: There are two machines, both of which are centos 5.x systems.

Machine 1 IP: 10.1.1.36 (as the server, the NFS service and Portmap service must be enabled)
Machine 2 IP: 10.0.1.31 (as the client, the Portmap service must be enabled)

2. NFS and Pormap/rpcbind Installation

Whether it is portmap of 5.x or rpcbind of 6.x, the core functions are summarized as: Port ing.
Note: The Centos 6.x and later systems use rpcbind instead of Portmap.
Centos 5 installation:
Yum install nfs-utils portmap
Centos 6 installation:
Yum install nfs-utils rpcbind

The ERROR repomd. xml: [Errno 14] pycurl error 7-"couldn't connect to host" is not prompted for yum installation ",
Solution:
// Corrected the baseurl
[Root @ etl02 hdfs_13] # cat/etc/yum. repos. d/HDP. repo
HDP-2.0.6
Name = HDP
Baseurl = http://download.fedoraproject.org/pub/epel/5/?basearch
Path =/
Enabled = 1
Gpgcheck = 0

3. Mount steps

Follow these steps to mount the 10.1.1.36 shared path/share to 10.0.1.31 only:
Step 1,Machine 1 and IP 10.1.1.36 act as the server. The configuration required is as follows:

1) configure the/etc/exports file

[Root @ Processor036/] # cat/etc/exports
/Share 10.0.1.31 (rw, sync)

Description: shared path/share, which can be viewed as IP 31, supports rw read/write operations, and sync synchronization.

2) Start Portmap (Role: Port ing)
[Root @ Processor036/] # sudo/etc/init. d/portmap restart
Stopping portmap: [OK]
Starting portmap: [OK]

3) Start the NFS service
[Root @ Processor036/] # sudo/etc/init. d/nfs restart
Shutting down NFS mountd: [OK]
Shutting down NFS daemon: [OK]
Shutting down NFS quotas: [OK]
Shutting down NFS services: [OK]
Starting NFS services: [OK]
Starting NFS quotas: [OK]
Starting NFS daemon: [OK]
Starting NFS mountd: [OK]

4) display the shared directory (display the shared directory in/etc/exports of hostname)
[Root @ Processor036/] # showmount-e
Export list for Processor036:
/Share 10.0.1.31

Step 2,In machine 2, Mount/share of machine 1 (server side) to machine 2
The second/share below is the share path under the Local Machine 10.0.1.31. You need to manually create a new one.
[Root @ WEB-W031/] # mount-t nfs 10.1.1.36:/share
View:
[Root @ WEB-W031/] # cd/share
[Root @ WEB-W031 share] # ls-al
Total 16
Drwxr-xr-x 3 root 4096 Mar 14.
Drwxr-xr-x 32 root 4096 Mar 14 ..
Drwxr-xr-x 2 root 4096 Mar 14 running 36test
