I am a linux newbie and I have a very basic question. I have three machines in production -
machineA 10.66.136.129 machineB 10.66.138.181 machineC 10.66.138.183
and all those machines have Ubuntu 12.04 installed in it and I have root access to all those three machines.
Now I am supposed to do below things in my above machines -
Create mount point /opt/exhibitor/conf Mount the directory in all servers. sudo mount <NFS-SERVER>:/opt/exhibitor/conf /opt/exhibitor/conf/
I have already created
/opt/exhibitor/conf directory in all those three machines as mentioned above.
Now I am trying to create a Mount Point. So I followed the below process -
Install NFS support files and NFS kernel server in all the above three machines
$ sudo apt-get install nfs-common nfs-kernel-server
Create the shared directory in all the above three machines
$ mkdir /opt/exhibitor/conf/
/etc/exports and added the entry like this in all the above three machines -
# /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /opt/exhibitor/conf/ 10.66.136.129(rw) /opt/exhibitor/conf/ 10.66.138.181(rw) /opt/exhibitor/conf/ 10.66.138.183(rw)
I have tried mounting on machineA like below from machineB and machineC and it gives me this error-
root@machineB:/# sudo mount -t nfs 10.66.136.129:/opt/exhibitor/conf /opt/exhibitor/conf/ mount.nfs: access denied by server while mounting 10.66.136.129:/opt/exhibitor/conf root@machineC:/# sudo mount -t nfs 10.66.136.129:/opt/exhibitor/conf /opt/exhibitor/conf/ mount.nfs: access denied by server while mounting 10.66.136.129:/opt/exhibitor/conf
/etc/exports file looks good? I am pretty sure, I have messed up my
exports file. As I have the same content in all the three machines in exports file.
Any idea what wrong I am doing here? And what will be the correct
/exports file here?
