搭建nfs服务器见：
修改想挂载的文件：vim /etc/exports
添加挂在目录
/home/share *(rw,no_root_squash)重新加载：
exportfs -rv其他机器访问测试：换个机子查看，会看到挂载路径
showmount -e 172.26.144.159在其他机器youxi2上挂载NFS：
mkdir /home/html获取挂载：
mount -t nfs 172.26.144.159:/home/share /home/html我是搭建在/home/share
在home/share下创建yaml文件 nfs-client.yaml
内容格式：
nfs:
server: "172.26.144.159" # This is the server IP address. Replace it with your own.
path: "/home/share" # Replace the exported directory with your own.

(1).实验环境
NFS服务器youxi1 192.168.1.6
测试主机youxi2 192.168.1.7
NFS是C/S模式，监听2049端口。
(2).实验
1）在NFS服务器youxi1上安装NFS
1
[root@youxi1 ~]# yum -y install rpcbind nfs-utils
2）启动NFS，并开机自启

[root@youxi1 ~]# systemctl start rpcbind
[root@youxi1 ~]# systemctl enable rpcbind
[root@youxi1 ~]# systemctl start nfs-server //NFS依赖rpcbind进行通讯，所以要先启动rpcbind
[root@youxi1 ~]# systemctl enable nfs-server
[root@youxi1 ~]# netstat -antup | grep 2049
tcp 0 0 0.0.0.0:2049 0.0.0.0:* LISTEN -
tcp6 0 0 :::2049 :::* LISTEN -
udp 0 0 0.0.0.0:2049 0.0.0.0:* -
udp6 0 0 :::2049 :::* -
3）测试主机youxi2安装nfs-utils
1
[root@youxi2 ~]# yum -y install nfs-utils
4）测试主机youxi2第一次测试
1
2
[root@youxi2 ~]# showmount -e 192.168.1.6
Export list for 192.168.1.6: //提示是空的
5）修改NFS服务器的配置文件/etc/exports，将已有的/www/html/文件夹共享出去

[root@youxi1 ~]# ll -d /www/html/
drwxr-xrwx 2 root root 20 5月 19 19:37 /www/html/
[root@youxi1 ~]# vim /etc/exports
/www/html/ 192.168.1.7(rw,no_root_squash) //可以共享给指定IP（192.168.1.7），也可以共享给指定网段（192.168.1.0），还可以共享给所有IP（*）.rw代表读写权限。
[root@youxi1 ~]# exportfs -rv //重新读取配置文件，而不中断服务
exporting 192.168.1.7:/www/html
/etc/exports配置文件中权限参数常用的有如下五个：
ro只读权限
rw读写权限
sync同步写入内存与磁盘当中
no_all_squash保留共享文件的UID和GID（默认）
no_root_squash使得root用户具有根目录的完全访问权限
6）测试主机youxi2第二次测试

[root@youxi2 ~]# showmount -e 192.168.1.6
Export list for 192.168.1.6:
/www/html 192.168.1.7
7）在测试主机youxi2上挂载NFS
1

[root@youxi2 ~]# mkdir /html
[root@youxi2 ~]# mount -t nfs 192.168.1.6:/www/html/ /html //这时候共享才开始正常使用
[root@youxi2 ~]# ls /html
passwd
还可以做开机挂载
1
2
[root@youxi2 ~]# vim /etc/fstab
192.168.1.6:/www/html /html nfs defaults 0 0 //添加一行
新建一个文件
1
2
3
[root@youxi2 ~]# touch /html/1.txt
[root@youxi2 ~]# ls /html/
1.txt passwd
8）NFS高并发下挂载优化常用参数（mount -o选项）
async：异步同步，此参数会提高I/O性能，但会降低数据安全（除非对性能要求很高，对数据可靠性不要求的场合。一般生产环境，不推荐使用）。
noatime：取消更新文件系统上的inode访问时间,提升I/O性能，优化I/O目的，推荐使用。
nodiratime：取消更新文件系统上的directory inode访问时间，高并发环境，推荐显式应用该选项，提高系统性能，推荐使用。
当然也可以写入/etc/fstab配置文件
