Linux/Ubuntu 16.04/18.04/19.10搭建NFS和TFTP服務器

1. NFS Server

1.1 Server (IP: 192.168.31.111)

• 安裝依賴

sudo apt-get install nfs-kernel-server nfs-common

• 創建共享目錄

mkdir -p /home/jiazhao/nfs
chmod 777 /home/jiazhao/nfs

• 修改/etc/exports配置文件

sudo vim /etc/exports

# **Add follow content**
/home/jiazhao/nfs 192.168.31.0/24(rw,sync,insecure,no_subtree_check,no_root_squash) 
#all client
/home/jiazhao/nfs *(rw,sync,insecure,no_subtree_check,no_root_squash) 

• 開啓rpcbind服務

sudo service rpcbind start 

• 重啓nfs-kernel-server服務

sudo service nfs-kernel-server restart

• 查看NFS server端口

rpcinfo -p localhost


# Verify /etc/exports is valid
showmount -e localhost

1.2 Client

sudo apt-get install nfs-common
showmount -e 192.168.31.111

# WSL1 not support now(2019-11-24)
sudo mount -t nfs 192.168.31.111:/home/jiazhao/nfs ./nfs

2. TFTP Server

2.1 Server (IP: 192.168.31.111)

• 安裝依賴

sudo apt-get install tftp-hpa tftpd-hpa

• 創建共享文件夾並添加權限

mkdir -p /home/jiazhao/tftp
chmod 777 /home/jiazhao/tftp

• 配置 xinetd.conf

sudo vim /etc/xinetd.conf

# 添加如下內容
defaults
{
    # Please note that you need a log_type line to be able to use log_on_success
    # and log_on_failure. The default is the following :
    # log_type = SYSLOG daemon info
}                                                                                                                                    
includedir /etc/xinetd.d  

• 配置/etc/default/tftpd-hpa

sudo vim /etc/default/tftpd-hpa

#添加如下內容
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/jiazhao/tftp"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="-l -c -s"

• **在/etc目錄下新建xinetd.d目錄，進入目錄創建tftp文件

sudo vim /etc/xinetd.d/tftp

# 添加如下內容
service tftp
{
    socket_type = dgram
    wait        = yes 
    disable     = no
    user        = root
    protocol    = udp 
    server      = /usr/sbin/in.tftpd
    server_args = -s /home/jiazhao/tftp
    per_source  = 11
    cps         = 100 2
    flags       =IPv4
}

• **重啓tftpd-hpa服務

sudo service tftpd-hpa restart

2.2 本地驗證

在tftp目錄下新建server.txt，在非tftp目錄下新建client.txt文件, 進入client.txt所在目錄，運行如下命令，完成後在client.txt目錄下多了個server.txt，在tftp目錄下多了個client.txt

tftp localhost 

# Get file from Server /home/jiazhao/tftp
get server.txt  

# put client file client.txt to Server /home/jiazhao/tftp
put client.txt

# Exit tftp mode
