Deploying NFS Services under Linux

Deploying NFS Services under Linux

General application Scenario: The server side allocates shared disk space, is mounted by one or more clients to achieve data sharing, centralized management and maintenance, access control and so on.

Steps:

Server Side-CentOS 7

• Install the necessary packages: Nfs-utils, Rpcbind
  yum -y install nfs-utils
yum -y install rpcbind
• Configuring the Etc/exports File
  Exports configuration of the parameter options are more, specific details with man to see and understand. Here is a description of the main 4 parameters:

All_squash : No matter what account the client uses to create the data, the owner is Nfsnobody
No_all_squash : Only the data created by the client with the root account, the owner is nfsnobody, the data created by other users is owned by other users themselves
Root_squash : Only the data created by the client with the root account is nfsnobody, and the data created by other users is owned by other users themselves.
No_root_squash : The root user has full access, and any user-created owner is the owner

• Let the NFS configuration file take effect. (Note: This step is required for each update made to/etc/exports)
  exportfs -rv

  -R #重新共享所以目录
  -V #输出详细信息

• Shutting down the firewall
  iptables -F
systemctl stop firewalldOrsystemctl disable firewalld
• Modify the/etc/selinux/config file to let selinux=disabled
  vim /etc/selinux/config
SELINUX=disabled
setenforce 0
• Start the appropriate service
  systemctl start rpcbind
systemctl start nfs-utils
systemctl start nfslock

Client

• Install the necessary package Nfs-utils, Rpcbind
  yum -y install nfs-utils
yum -y install rpcbind
• Shutting down the firewall
  iptables -F
• Modify the/etc/selinux/config file to let selinux=disabled
  vim /etc/selinux/config
SELINUX=disabled
setenforce 0
• Use the mkdir command to create the necessary mount directory, for example:
  mkdir /mnt/nfs
• To view NFS information shared by the server, use the command showmount
  SHOWMOUNT-E server_ip
• Use the Mount command to mount the server's shared directory, for example:
  Mount-t NFS ServerIP:/nfs/mnt/nfs
• Use df-th to verify Mount status
  df -Th
