6.1.2 CentOS 7
From the host, install the necessary tools using yum:
% sudo yum install nfs-utils
1
From the host, allow NFS past SELinux
2
:
% sudo setsebool -P nfs_export_all_rw 1
% sudo setsebool -P use_nfs_home_dirs 1
From the host, allow NFS past the firewall:
% sudo firewall-cmd --permanent --zone=public --add-service=nfs
% sudo firewall-cmd --permanent --zone=public --add-port=2049/udp
% sudo firewall-cmd --permanent --zone=public --add-service=mountd
% sudo firewall-cmd --permanent --zone=public --add-service=rpc-bind
% sudo firewall-cmd --reload
Define the export by creating a new file that has the extension “exports”. If it does not have that extension, it
will be ignored. Add the following lines to that file and replace “XX.XX.XX.XX/MM” with a valid netmask for the
DHCP range that the SDR will be set to for your network (e.g. 192.168.0.0/16).
% sudo vi /etc/exports.d/user_ocpi.exports
/opt/opencpi XX.XX.XX.XX/MM(rw,sync,no_root_squash,crossmnt)
/home/user/ocpi_projects/core XX.XX.XX.XX/MM(rw,sync,no_root_squash,crossmnt)
/home/user/ocpi_projects/assets XX.XX.XX.XX/MM(rw,sync,no_root_squash,crossmnt)
If the file system that you are mounting is XFS, then each mount needs to have a unique fsid defined. Instead, use:
% sudo vi /etc/exports.d/user_ocpi.exports
/opt/opencpi XX.XX.XX.XX/MM(rw,sync,no_root_squash,crossmnt,fsid=33)
/home/user/ocpi_projects/core XX.XX.XX.XX/MM(rw,sync,no_root_squash,crossmnt,fsid=34)
/home/user/ocpi_projects/assets XX.XX.XX.XX/MM(rw,sync,no_root_squash,crossmnt,fsid=35)
Restart the services that have modified for the changes to take effect:
% sudo systemctl enable rpcbind
% sudo systemctl enable nfs-server
% sudo systemctl enable nfs-lock
% sudo systemctl enable nfs-idmap
% sudo systemctl restart rpcbind
% sudo systemctl restart nfs-server
% sudo systemctl restart nfs-lock
% sudo systemctl restart nfs-idmap
* Note: Some of the “enable” commands may fail based on your package selection, but should not cause any problems.
NOTE: You will need to add the ocpi.bsp.e310 project to your list of exports (in /etc/exports.d/user_ocpi.
exports).

nfs-utils-lib was rolled into nfs-utils starting with CentOS 7.2, if using eariler versions of CentOS 7, nfs-utils-lib will need
to be explicitly installed

You can use getsebool to see if these values are already set before attempting to set them. Some security to ols may interpret the
change attempt as a system attack.
