Editor to share with you how to build CentOS7 server NFS server file sharing, I hope you will learn something after reading this article, let's discuss it together!

NFS server file sharing

When multiple servers are clustered, because only one server uploads file attachments when uploading, there will be attachments that other servers cannot find. At this point, you need to share the folder uploaded by attachments so that all servers in the cluster can access the uploaded attachments.

Server side

Turn off the firewall because the NFS port rules are complex and difficult to set.

Install nfs

Yum install nfs-utils rpcbind

Configure nfs: vim / etc/exports

/ data/share 192.168.0.10 (rw,sync,all_squash)

Where the ip address refers to the IP that can access the share. If multiple IP access is allowed, 192.168.0.* can be used.

Sharing multiple folders can set up multiple rows.

About permissions

The user of the shared directory is nfsnobody, which can be set (rw,sync,all_squash,anonuid=xxx,anongid=xxx)

Or set the permissions of the shared directory to 777: chmod 777 / data/share

# Let the configuration take effect after modifying exports exportfs-arv# starts rpcbind service systemctl start rpcbindsystemctl enable rpcbind# starts nfs service systemctl start nfssystemctl enable nfs# check whether the showmount-e client is configured # start rpcbind service systemctl start rpcbindsystemctl enable rpcbindshowmount-e 192.168.0.2 mount mount-t nfs 192.168.0.20:/data/share / mnt/nfs# unmount umount / mnt/share boot mount

Modify the file vim / etc/rc.d/rc.local by adding the following code:

Mount-t nfs-o nosuid,noexec,nodev,rw,bg,soft,rsize=32768,wsize=32768 192.168.0.20:/data/share / mnt/nfs

If the file does not have execute permissions, you need to increase the execute permissions:

Chmod + x / etc/rc.d/rc.local automatically mounts autofs

Auto-mount cannot see the folder when it is not in use, and it will be automatically mounted and displayed only when you enter the folder with or with the command. Therefore, it is not very convenient to use for deployment.

Boot mount and automatic mount choose one of the two and cannot be used at the same time. For deployment, boot mount is generally used. If it is just a simple file sharing, you can use autofs.

# install yum install autofs

Configuration file vim / etc/auto.master, add the code:

/ mnt/nfs / etc/auto.nfs

Create the file vim / etc/auto.nfs, which is as follows:

Public-rw,bg,soft,rsize=32768,wsize=32768 192.168.0.20:/data/share

The corresponding mount directory is / mnt/nfs/public. Do not create these folders manually. Autofs will handle them automatically.

# start systemctl start autofs# start self-start systemctl enable autofs# stop systemctl stop autofs# close self-start systemctl disable autofs after reading this article, I believe you have some understanding of "how to set up NFS server file sharing on CentOS7 server".
