File Sharing between linux and file sharing in linux

File Sharing between linux and file sharing in linux

Because an application was loaded yesterday, the application will upload files. To ensure file synchronization, you need to share a file. In Linux, Network File Service (Network File System NFS) can be used to share files.

Generally, the NFS system is installed in linux by default. First, set host A. A directory in host A is shared and can be read and written by other hosts.

Vi/etc/exports # set in this file

/Home/work * (rw, sync, no_root_squash)

This statement indicates that all hosts can share/home/work on host A. the permissions are as follows:

Rw: read/write permission. the read-only permission is ro;

Sync: indicates that all data is written to the shared data upon request, that is, data is synchronized to the memory and hard disk;

No_root_squash: Allows clients mounted to this directory to enjoy the root identity of the host.

Edit and save and execute the following command:

Servicenfs restart ---- Enable nfs service

Showmount-e 172.16.50.21 (this command can check all mounted directories on the host)

For host B (the directory that needs to be shared with A), perform the following operations:

Vi/etc/fstab

172.16.50.21:/home/apache-tomcat-7.0.34/webapps/CHMOManager/download/softversion/home/tomcat/apache-tomcat-7.0.34/webapps/CHMOManager/download/softversion nfs ults 0 0

In this example, the file system of directory 21 is nfs, which is shared to host B/home/tomcat/apache-tomcat-7.0.34/webapps/CHMOManager/download/softversion, ults is the default configuration

Then run mount-a to mount the file. (Do not run this command in the shared directory. Otherwise, the command cannot be executed)
