NFS 实战

版权声明: https://blog.csdn.net/shadow2017/article/details/84784023

本文是操作过程稍微整理而成。。。

注意:共享文件目录,关闭seliunx iptables

客户端:192.168.1.141

服务端:192.168.1.145

在服务端安装配置操作:

[root@xie2 ~]# yum install nfs* -y

[root@xie2 ~]# rpm -ql nfs-utils|more

[root@xie2 etc]# rpm -qa  | egrep "nfs|rpcbind"

nfs-utils-lib-1.1.5-13.el6.x86_64

rpcbind-0.2.0-16.el6.x86_64

nfs-utils-1.2.3-78.el6_10.1.x86_64

nfs4-acl-tools-0.3.3-8.el6.x86_64

nfs-utils-lib-devel-1.1.5-13.el6.x86_64

[root@xie2 etc]#  rpm -ql nfs-utils

保存默认配置文件

[root@xie2 ~]# vim /etc/nfsmount.conf

共享配置文件

[root@xie2 ~]# mkdir -p /data/mydata

[root@xie2 ~]# ll /data/

总用量 4

drwxr-xr-x. 2 root root 4096 12月  4 00:32 mydata

[root@xie2 ~]# chmod 666 /data/mydata/

[root@xie2 etc]# chown -R nfsnobody:nfsnobody /data/

NFS 主要配置文件:添加共享目录

[root@xie2 etc]# vim exports

/data/      *(rw,no_root_squash,no_all_squash,sync)

#/data/ 需要共享的目录ro                      只读访问

#rw                      读写访问

#sync                    所有数据在请求时写入共享

#all_squash              共享文件的UID和GID映射匿名用户anonymous,适合公用目录。

#no_all_squash           保留共享文件的UID和GID(默认)

#root_squash             root用户的所有请求映射成如anonymous用户一样的权

#限(默认)

#no_root_squash           root用户具有根目录的完全管理访问权限

#Linux客户端,如何想使用这个NFS文件系统,需要在客户端挂载,挂载命令为:

[root@xie2 mydata]# mkdir 20181203

[root@xie2 mydata]# touch test_jfedu.txt

[root@xie2 mydata]# ls

20181203 test_jfedu.txt

[root@xie2 mydata]#

[root@xie2 mydata]#

[root@xie2 mydata]# cd

[root@xie2 etc]#  /etc/init.d/rpcbind start  

[root@xie2 etc]# /etc/init.d/nfs start

                                  

[root@xie2 etc]# chkconfig nfs on

[root@xie2 etc]# chkconfig --list nfs

nfs             0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

[root@xie2 etc]# chkconfig --list rpcbind

rpcbind         0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

[root@xie2 ~]# netstat -tnl

[root@xie2 ~]# yum install telnet -y

[root@xie2 ~]# telnet 192.168.1.141

Trying 192.168.1.141...

telnet: connect to address 192.168.1.141: No route to host

[root@xie2 ~]# telnet 192.168.1.141 111

Trying 192.168.1.141...

telnet: connect to address 192.168.1.141: No route to host

不通;;;、

关闭防火墙,selinux iptable

[root@xie2 ~]# /etc/init.d/iptables stop

iptables:将链设置为政策 ACCEPT:filter [确定]

iptables:清除防火墙规则: [确定]

iptables:正在卸载模块: [确定]

[root@xie2 ~]# cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

# targeted - Targeted processes are protected,

# mls - Multi Level Security protection.

SELINUXTYPE=targeted

[root@xie2 ~]# telnet 192.168.1.141 111

Trying 192.168.1.141...

Connected to 192.168.1.141.
