1. Required packages for NFS installation;
Need nfs-utils and rpcbind;
2. Use the following commands to check if the above packages are already installed on the system:
rpm -qa|grep nfs
rpm -qa|grep rpcbind
If already installed, proceed directly to step 3; if not, run the following command to install:
yum install nfs-utils rpcbind
3. Configure the server side
Create the mount directory and mount it, use the following commands:
mkdir /opt/data
cd /opt/data
mkdir test
Then edit the /etc/exports file, which defines the shared directories and sharing rules:
vi /etc/exports
Add the following line to the file:
/opt/data 192.168.1.0/24(rw,no_root_squash)
This line means the NFS shared directory is /opt/data, accessible by IPs in the 192.168.1.0/24 subnet, with read-write access, and clients can access as root user;
After making changes, save and exit;
Then run service nfs restart to restart the NFS service;
4. Disable the firewall, use the following command:
service iptables stop
5. Configure the client side
The operating system on the client is the same as on the server; nfs-utils and rpcbind also need to be installed;
After installation, check whether you can access the NFS service normally:
showmount -e 192.168.1.104
The following result indicates normal access:
Export list for 192.168.1.104
/opt/data 192.168.1.104
Then use the following command to create an association between the local directory and the server mount point:
mkdir /opt/dataltest
mount -t nfs 10.0.113.237:/opt/data/ /opt/data/
Then run ls /opt/data to see the files in the shared directory on the server from the client side, and you can read from and write to the files in the shared directory.
6. Configure automatic mounting at boot as follows:
vi /etc/fstab
Add the following line at the end of the file:
192.168.0.104:/opt/data /opt/data nfs rw 0 2
