RedHat 5.5
鉴于现在用户一个项目一般都是用多台机器进行处理，那么对ArcGIS Server来说，尽管多台机器进行处理，但是地图切片的文件夹肯定是一个地方的，那么Linux的共享文件夹就需要大家掌握了，下面就试验一下怎么在Linux环境下设置共享文件夹。
机器1：RedHat，192.168.100.203
机器2：RedHatA，192.168.100.204
目的：将RedHat机器里面的两个文件夹进行共享
1：将机器1的 /opt/arcgis/server10.0/server/serverdir 共享到机器2的 /opt/arcgis/server10.0/server/serverdir
2：将机器1的 /home/aaa 共享到机器2的/home/bbb
修改机器1的/etc/exports文件
/opt/arcgis/server10.0/server/serverdir 192.168.100.204(rw,no_root_squash,async
) 192.168.100.203(rw,no_root_squash,async)
/home/aaa 192.168.100.204(rw,no_root_squash,async) 192.168.100.203(rw,no_root_sq
uash,async)
相关格式：
共享路径 共享给机器IP（rw,no_root_squash,async) 共享给机器2 IP（rw,no_root_squash,async)
重启nfs和portmap服务
[root@RedHat ~]# service nfs restart
Shutting down NFS mountd: [ OK ]
Shutting down NFS daemon: [ OK ]
Shutting down NFS quotas: [ OK ]
Shutting down NFS services:[ OK ]
Starting NFS services: [ OK ]
Starting NFS quotas: [ OK ]
Starting NFS daemon: [ OK ]
Starting NFS mountd: [ OK ]
[root@RedHat ~]# service portmap restart
Stopping portmap: [ OK ]
Starting portmap: [ OK ]
设置机器2
修改/etc/fstab，添加
192.168.100.203:/opt/arcgis/server10.0/server/serverdir /opt/arcgis/server10.0/server/serverdir nfs rsize=8192,wsize=8192,timeo=14,intr
192.168.100.203:/home/aaa /home/bbb nfs rsize=8192,wsize=8192,timeo=14,intr
格式：
共享机器的IP: 共享机器的路径 本机的映射路径 nfs rsize=8192,wsize=8192,timeo=14,intr
然后，使用mount 本机器的路径进行mount上
查询mount 会查看本机器的路径是否mount上
[root@RedHatA ~]# mount /home/bbb
[root@RedHatA ~]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /proc/fs/vmblock/mountPoint type vmblock (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
192.168.100.203:/home/aaa on /home/bbb type nfs (rw,rsize=8192,wsize=8192,timeo= 14,intr,addr=192.168.100.203)
[root@RedHatA ~]# mount /opt/arcgis/server10.0/server/serverdir/
[root@RedHatA ~]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /proc/fs/vmblock/mountPoint type vmblock (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
192.168.100.203:/home/aaa on /home/bbb type nfs (rw,rsize=8192,wsize=8192,timeo= 14,intr,addr=192.168.100.203)
192.168.100.203:/opt/arcgis/server10.0/server/serverdir on /opt/arcgis/server10. 0/server/serverdir type nfs (rw,rsize=8192,wsize=8192,timeo=14,intr,addr=192.168 .100.203)
相关测试：
在机器1上共享的路径下创建一个文件，在机器2的相关映射路径下能够看到。
Solaris 10
以一台机器为例：我的/export/home路径下有四个文件夹：aaa、bbb、ccc、ddd
目的是：
共享/export/home/aaa 映射到/export/home/bbb
共享/export/home/ccc 映射到/export/home/ddd
修改/etc/dfs/dfstab文件
bash-3.00# vi /etc/dfs/dfstab
"/etc/dfs/dfstab" 12 lines, 430 characters
# Place share(1M) commands here for automatic execution
# on entering init state 3.
#
# Issue the command 'svcadm enable network/nfs/server' to
# run the NFS daemon processes and the share commands, after adding
# the very first entry to this file.
#
# share [-F fstype] [ -o options] [-d "<text>"] <pathname> [resource]
# .e.g,
# share -F nfs -o rw=engineering -d "home dirs" /export/home2
share -F nfs -o /export/home/ccc
share -F nfs -o /export/home/aaa
因为这是在本机测试，共享给本机这两个文件夹
share -F nfs -o /export/home/aaa
如果是共享给另外一台或者两台机器
share -F nfs -o rw=app1:app2 /opt/arcgis/server/serverdir
share -F nfs -o rw=59.255.44.13 /opt/arcgis/server/serverdir
app1、app2、59.255.44.13这些都是共享目的机器的机器名和IP.
然后执行share命令
bash-3.00# share /export/home/aaa
bash-3.00# share /export/home/ccc
bash-3.00# share
- /export/home/ccc rw ""
- /export/home/aaa rw ""
我们可以看到这些文件夹已经共享上了
然后我们进行映射修改/etc/vfstab
bash-3.00# vi /etc/vfstab
"/etc/vfstab" 14 lines, 521 characters
#device device mount FS fsckmount mount
#to mount to fsck point typepassat boot options
#

/proc - /proc proc- no -
/dev/dsk/c0d0s1 - - swap- no -
/dev/dsk/c0d0s0 /dev/rdsk/c0d0s0/ ufs 1 no -
/dev/dsk/c0d0s7 /dev/rdsk/c0d0s7/export/homeufs 2 yes

192.168.205.140:/export/home/ccc - /export/home/ddd nfs - yes -
192.168.205.140:/export/home/aaa - /export/home/bbb nfs - yes -
相关格式
那个机器共享的IP：共享机器共享的路径 - 映射到本机的路径 nfs - yes -
192.168.205.140:/export/home/ccc - /export/home/ddd nfs - yes -
192.168.205.140:/export/home/aaa - /export/home/bbb nfs - yes -
如上所示，共享的/export/home/aaa文件夹，映射到/export/home/bbb即可
然后执行mount命令
bash-3.00# mount /export/home/ddd
nfs mount: mount: /export/home/ddd: Device busy
bash-3.00# mount /export/home/bbb
nfs mount: mount: /export/home/bbb: Device busy
bash-3.00# mount

取消

我们看到，原来的/export/home/ddd已经没有mount了
取消共享
bash-3.00# share
- /export/home/ccc rw ""
- /export/home/aaa rw ""
bash-3.00# unshare /export/home/ccc
bash-3.00# share
- /export/home/aaa rw ""
但是如果需要永久共享，应该屏蔽/etc/dfs/dfstab文件里面的共享信息
以上是solaris环境，RedHat可以类比。
