NFS server construction

This time, the procedure is to build an NFS server in the verification environment and mount it as an ESXi datastore.

Deploy virtual machine

First, configure the virtual hardware settings for the virtual machine. -Log in to the deployment destination ESXi. -Store the ISO file in any location from Storage> Datastore> Datastore Browser. -From the creation / registration of the virtual machine, set the following and complete. ● Selection of creation type -Create a new virtual machine ● Name and guest OS selection ・ The name is CentOS7 (optional) · Compatibility is ESXi 6.x virtual machine -Guest OS family is linux, guest OS version is CentOS 7 (64-bit) ● Storage selection -Select any data store ● Customize settings ・ CPU / memory / hard disk / network adapter is optional -Select the ISO file stored in any location in the data store on the CD / DVD drive 1 and select it. Put ☑ in the connection when powering on

Next, start the virtual machine and install the OS. The installation settings are optional, but the software selection chooses a minimal installation. After installation, reboot.

nfs settings

-Create a directory shared by nfs. This time it's / home / nfs. When creating a directory, you need to change the owner of the directory to nfsnobody.

# mkdir /home/nfs
# ll /home/
Total 0
drwxr-xr-x.3 root root 17 November 8 18:13 nfs

# chown -R nfsnobody:nfsnobody /home/nfs/
# ll /home/
Total 0
drwxr-xr-x.3 nfsnobody nfsnobody 17 November 8 18:13 nfs

-Set the network and options that can be shared with the directory shared by nfs.

# vi /etc/exports
/home/nfs xxx.xxx.xxx.xxx/xx(rw) 

# exportfs
/home/nfs       xxx.xxx.xxx.xxx/xx

About nfs parameters

・ Set the following.

 # /exported/directory xxx.xxx.xxx.xxx/xx(ro/rw)
parameter Explanation
/exported/directory Specify the directory to share
xxx.xxx.xxx.xxx/xx Specify a network that can be shared, no prefix required for hosts
ro The file system to be exported will be read-only
rw The file system to be exported becomes readable and writable

firewall settings

-When using nfs version 4, set the firewall service port to be open below.

# firewall-cmd --permanent --add-service=nfs
success

# firewall-cmd --reload
success

# firewall-cmd --list-all
public (default, active)
  interfaces: eno16780032
  sources:
  services: dhcpv6-client nfs ssh
  ports:
  masquerade: no
  forward-ports:
  icmp-blocks:
  rich rules:

-When using nfs version 3, disable the firewall. It seems that the port in nfs is not fixed.

Nfs mount from ESXi (nfs client)

-Log in to ESXi of the nfs client. -Press Storage> Datastore> New Datastore. -Select the mount of the NFS datastore and click Next. -Any name, enter the corresponding IP address for the NFS server and the directory to be shared with the NFS share. If the NFS version is NFS4, leave the username / password blank and press Next.

Things to note

· If you do not create an nfs user You have to set the shared directory to have access with nfsnobody. -If you use nfs version 3, you have to disable the firewall.
