nfs的安装和配置

nfs的安装和配置，经常安装，做个比较复制快些。 1. yum 安装 yum install nfs-utils -yyum install rpcbind -yyum install mount.n

nfs的安装和配置，经常安装，做个比较复制快些。

1. yum 安装

yum install nfs-utils -yyum install rpcbind -yyum install mount.nfs -y

 

2. 选择好要nfs的目录

mkdir /var/exportfsmkdir /var/exportfs/uploadmkdir /var/exportfs/share

如果是挂载的其它盘则使用

cat /etc/fstab/dev/vdb1		/var/redis		ext4	defaults	0 0/dev/vdb2		/var/exports		ext4	defaults	0 0

mount -a    //挂载

或者:

mount [-t type] [-o option] device dirmount -t ext4 /dev/vdb1 /var/redis//卸载umount /dev/vdb1    或umount /var/redis

 

3. 编写exports文件（nfs配置文件）

cat /etc/exports/var/exportfs/upload		10.30.196.147/32(rw,no_root_squash,no_all_squash,sync) 10.30.196.142/32(rw,no_root_squash,no_all_squash,sync) 10.27.109.112/32(rw,no_root_squash,no_all_squash,sync) 10.27.110.20/32(rw,no_root_squash,no_all_squash,sync) 10.27.110.13/32(rw,no_root_squash,no_all_squash,sync)/var/exportfs/share		10.30.196.147/32(rw,no_root_squash,no_all_squash,sync) 10.30.196.142/32(rw,no_root_squash,no_all_squash,sync) 10.27.109.112/32(rw,no_root_squash,no_all_squash,sync) 10.27.110.20/32(rw,no_root_squash,no_all_squash,sync) 10.27.110.13/32(rw,no_root_squash,no_all_squash,sync) 10.27.60.27/32(rw,no_root_squash,no_all_squash,sync) 10.28.109.8/32(rw,no_root_squash,no_all_squash,sync) 10.28.142.168/32(rw,no_root_squash,no_all_squash,sync) 10.27.210.240/32(rw,no_root_squash,no_all_squash,sync)

设定那些机器具有那些权限

 

4. 启动nfs

service rpcbind startservice nfs start

如果出现

Starting NFS mountd: rpc.mountd: svc_tli_create: could not open connection for udp6rpc.mountd: svc_tli_create: could not open connection for tcp6rpc.mountd: svc_tli_create: could not open connection for udp6rpc.mountd: svc_tli_create: could not open connection for tcp6rpc.mountd: svc_tli_create: could not open connection for udp6rpc.mountd: svc_tli_create: could not open connection for tcp6                                                           [FAILED]

这个是ipv6的支持，不需要则可以

vi /etc/netconfig udp tpi_clts v inet udp - -tcp tpi_cots_ord v inet tcp - -#udp6 tpi_clts v inet6 udp - -#tcp6 tpi_cots_ord v inet6 tcp - -rawip tpi_raw - inet - - -local tpi_cots_ord - loopback - - -unix tpi_cots_ord - loopback - - -

如果出现

Starting NFS daemon: rpc.nfsd: writing fd to kernel failed: errno 111 (Connection refused)rpc.nfsd: address family inet6 not supported by protocol TCPrpc.nfsd: unable to set any sockets for nfsd

这是rpcbind没有启动，需要先启动rpcbind, service rpcbind start

6. 需要主要的地方：

service rpcbind startrpcbind需要比nfs先启动然后在service nfs start过程中需要确保nfs 和rpcbind 服务会开机启动。chkconfig rpcbind --listchkconfig nfs --listchkconfig rpcbind onchkconfig nfs on

 

7. nfs客户机

也需要rpcbind，和nfs。

使用showmount -e 192.168.111.111来查看

使用mount -t nfs 192.168.111.111:/var/exportfs/share /opt/share

还可以是用 /etc/fstab里添加如下代码实现开机自动挂载

10.27.110.25:/var/exportfs/upload	/usr/local/upload	nfs	defaults	0 010.27.110.25:/var/exportfs/share		/opt/share		nfs	defaults	0 0
