nfs 实际应用记录

CentOS

# rpm -qa nfs-utils rpcbind
nfs-utils-1.3.0-0.54.el7.x86_64
rpcbind-0.2.0-38.el7.x86_64

 

ubuntu

# 服务端
apt install nfs-kernel-server
# 客户端
apt install nfs-common

netstat -tl

vi /etc/exports/root/sharedata  *(rw,sync,no_root_squash,no_all_squash) 

 

 

# 启动 NFS 服务
$ service nfs start
# 或者使用如下命令亦可
/bin/systemctl start nfs.service# 启动 NFS 服务后 rpc 服务已经启用了对 NFS 的端口映射列表
