详解AIX 5L NFS Server的建设(1)(2)
二、配置AIX 5L NFS Client
nfs的client配置比较简单,需要portmap服务正常即可。
- #lssrc -s portmap
- Subsystem Group PID Status
- portmap portmap 225506 active
关于mount的信息,是写在/etc/filesystems中的,如
- #more /etc/filesystems
- ......
- /mydisk:
- dev = "/disk1"
- vfs = nfs
- nodename = dbbak
- mount = false
- type = nfs3
- options = soft,intr,retry=2,rsize=32768,wsize=32768,timeo=300,proto=tcp
- account = false
- ......
其中nodename指定了服务器的名字,其对应的ip在/etc/hosts中体现,dev指定了服务器的export出来的目录。
关于更多的options的设置,可以查阅更多的nfs的文档。
其详细信息,也可以在smit中获得,如smit nfs–>Network File System (NFS) –>Add a File System for Mounting或者是Change / Show Attributes of an NFS File System。如
- #smit chnfsmnt
- * PATHNAME of mount point /mydisk
- * PATHNAME of Remote Directory [/disk1]
- * HOST where remote directory resides [dbbak]
- Mount type NAME [nfs3]
- * Use SECURE mount option? no
- * Remount file system now, both
- update /etc/filesystems or both?
- * /etc/filesystems entry will mount the directory no
- on system RESTART.
- * MODE for this NFS file system read-write
- * ATTEMPT mount in background or foreground? foreground
- NUMBER of times to attempt mount [2]
- Buffer SIZE for read [32768]
- Buffer SIZE for writes [32768]
- NFS TIMEOUT. In tenths of a second [300]
- NFS version for this NFS file system any
- Transport protocol to use tcp
- Internet port NUMBER for server []
- * Allow execution of SUID and sgid programs yes
- in this file system?
- * Allow DEVICE access via this mount? yes
- * Server supports long DEVICE NUMBERS? yes
- * Mount file system soft or hard soft
验证 mountd、portmap 和 nfsd 守护程序正在 NFS 服务器上运行,请在客户机 shell 提示符下输入以下命令:
- #/usr/bin/rpcinfo -u server_name mount
- #/usr/bin/rpcinfo -u server_name portmap
- #/usr/bin/rpcinfo -u server_name nfs
如果守护程序在服务器运行,会返回以下响应:
- program 100005 version 1 ready and waiting
- program 100000 version 2 ready and waiting
- program 100003 version 2 ready and waiting
程序号分别与命令对应,如前例中所示。如果没有返回类似的响应,请在服务器控制台上登录服务器并按照获取 NFS 守护程序的当前状态中的指示信息检查守护程序的状态。
- #showmount -e server_name
该命令列出了由 server_name 当前导出的所有文件系统。
注意:如果在AIX上mount linux的nfs文件系统,可能需要特殊执行:
- #nfso -o nfs_use_reserved_ports=1
