NFS：on RHEL 6
NFS会依赖一些服务。
在RHEL5中，它们是：portmap
在RHEL6中，它们是：rpcbind
操作系统版本：
|
1 2 3 |
[root@oracle-me ~]# cat /etc/redhat-release CentOS release 6.8 (Final) [root@oracle-me ~]# |
启动依赖的服务：
|
1 2 3 4 5 6 7 8 9 |
[root@oracle-me ~]# service rpcbind status rpcbind is stopped [root@oracle-me ~]# [root@oracle-me ~]# service rpcbind start Starting rpcbind: [ OK ] [root@oracle-me ~]# [root@oracle-me ~]# service rpcbind status rpcbind (pid 14243) is running... [root@oracle-me ~]# |
启动NFS：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
[root@oracle-me ~]# service nfs status rpc.svcgssd is stopped rpc.mountd dead but subsys locked nfsd dead but subsys locked rpc.rquotad dead but subsys locked [root@oracle-me ~]# [root@oracle-me ~]# service nfs start Starting NFS services: [ OK ] Starting NFS quotas: [ OK ] Starting NFS mountd: [ OK ] Starting NFS daemon: [ OK ] Starting RPC idmapd: [ OK ] [root@oracle-me ~]# [root@oracle-me ~]# |
如果没有启动依赖的服务，而启动NFS服务，将会遇到下面的报错：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
[root@oracle-me ~]# service nfs status rpc.svcgssd is stopped rpc.mountd is stopped nfsd is stopped rpc.rquotad is stopped [root@oracle-me ~]# [root@oracle-me ~]# service nfs start Starting NFS services: [ OK ] Starting NFS quotas: Cannot register service: RPC: Unable to receive; errno = Connection refused rpc.rquotad: unable to register (RQUOTAPROG, RQUOTAVERS, udp). [FAILED] Starting NFS mountd: [FAILED] Starting NFS daemon: rpc.nfsd: writing fd to kernel failed: errno 111 (Connection refused) rpc.nfsd: unable to set any sockets for nfsd [FAILED] [root@oracle-me ~]# |
配置需要共享的目录：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
[root@oracle-me ~]# cat /etc/exports /nfs_me 192.168.92.0/24(rw) [root@oracle-me ~]# [root@oracle-me ~]# exportfs -auv [root@oracle-me ~]# showmount -e localhost Export list for localhost: [root@oracle-me ~]# [root@oracle-me ~]# exportfs -arv exporting 192.168.92.0/24:/nfs_me [root@oracle-me ~]# [root@oracle-me ~]# showmount -e localhost Export list for localhost: /nfs_me 192.168.92.0/24 [root@oracle-me ~]# |
客户端：
查看【showmount】命令是由什么软件包提供的：
|
1 2 3 |
[root@oracle-me ~]# rpm -qf /usr/sbin/showmount nfs-utils-1.2.3-75.el6.x86_64 [root@oracle-me ~]# |
