Centos7服务器之间共享盘挂载

NFS (Network File System) Mounts
Master: 192.168.138.129
Client: 192.168.138.128

ROOT用户下操作设置服务器端(192.168.138.129)
yum -y install rpcbind nfs-utils
mkdir /share/
chmod 755 -R /share/

vi /etc/exports
添加
/share/ 192.168.138.128(rw,no_root_squash,no_all_squash,sync)

exportfs -r
rpcinfo -p
启动服务
systemctl start rpcbind
systemctl start nfs
开机启动
systemctl enable rpcbind
systemctl enable nfs
查看本机是否可连
showmount -e localhost

ROOT用户下操作设置客户端(192.168.138.128)
yum -y install rpcbind nfs-utils
showmount -e 192.168.138.129(查看服务器端挂载)
mkdir -p /client/share
mount -t nfs 192.168.138.129:/share /client/share/ -o nolock,nfsvers=3,vers=4

开机自动启动
vim /etc/rc.d/rc.local
末尾添加
mount -t nfs 192.168.138.129:/share /client/share/ -o nolock,nfsvers=3,vers=4
无效的话，开下权限
chmod +x /etc/rc.d/rc.local

此时在/client/share/目录下可看到192.168.138.129:/share 下相同的文件信息

mount -l 查看所有挂载
umount /c/share  卸载
