How to configure NFS service sharing in CentOS7
This article introduces the knowledge of "how to configure NFS service sharing in CentOS7". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Detailed configuration 1. Prophase configuration
Turn off the firewall and selinux of the server and the client, where the server refers to the storage server that needs to be shared, and the client refers to the other 8 computing nodes. All of the following commands are in the CentOS7 environment
1.1 turn off the firewall
Systemctl stop firewalld
1.2 set selinux to license mode (or turn off)
Etenforce 0
(if you want to disable it, you need to change the configuration file, set SELINUX to disabled, and the restart takes effect.)
two。 Server configuration
2.1 install the required software packages (using yum)
Yum install-y rpc-bind nfs-utils
2.2 create the folder you want to share, for example, / datas
Mkdir / datas
2.3 set the permissions of the shared directory to be readable and writable for all users
Chmod-R 777 / datas
2.4 modify the main configuration file / etc/exports of the NFS service
Vim / etc/exports
# add the following rules
/ datas * (rw,sync)
The rule states: / datas represents shared files, * represents that all hosts can access, rw refers to read and write permissions, and sync indicates the use of synchronization. Other more precise options are as follows:
2.5 enable NFS service
Systemctl start nfs
Now that the nfs on the server is configured, recall that we have mainly done:
Turn off the firewall and selinux to share the directory / datas we created through the nfs main configuration file / etc/exports to open the nfs service
Ps: if you want to share one of the server's hard drives, simply mount the / datas directory to that hard disk using the mount command. The command to view the hard disk and mount is:
Df-h
For example, mount a hard disk device / dev/sdd to / datas
Mount / dev/sdd / datas
Next, configure the client
3. Client configuration
3.1 turn off the firewall and selinux
Same as above
3.2 install NFS
Same as above
Mount the shared directory on the server to the local / data-nfs directory. My ip here is the ip of the IB card. If there is no IB driver, you can use the intranet ip,/data-nfs directly. This is my custom directory.
Mount-t nfs 12.12.12.29:/datas / data-nfs
At this point, when the client is configured, accessing the / data-nfs directory is equivalent to accessing the server's / datas directory
Ps: problems may occur after the above configuration is rebooted. It is recommended to set the configuration to boot and execute.
