实际上很早以前HostHatch就支持了，只不过我比较懒就一直没弄。
根据官网的文档，他们支持VPS之间部署私有网络，不过需要注意的是：
- 必须先向服务人员提交开通第二块网卡的支持票；
- 不支持DHCP，必须自己手动配置第二块网卡的网络信息。
最近不是部署了个下载站么，就索性把这个功能调整好了。
首先你看到自己网卡的状态应该类似这样：
enp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000。一开始我尝试先用了官方推荐的netplan编辑/etc/netplan/90-private.yaml文件，发现一直总是配不好。
network:
ethernets:
eth1:
addresses:
- 192.168.10.1/24
match:
macaddress: 00:22:xx:xx:xx:xx
version: 2我后来更换到了NetworkManager来管理。

[ipv6]
addr-gen-mode=stable-privacy

[ethernet]
mac-address-blacklist=接下来重新加载配置。
sudo nmcli con reload
sudo nmcli con up "enp2s0-static"接下来验证是否配置成功。如果类似于这种就算配置成功了。
root@Nicky:~# ip link show enp2s0

root@Nicky:~#如果有类似错误可能要修改权限问题。
** (process:1620): WARNING **: 15:40:42.956: Permissions for /etc/netplan/90-private.yaml are too open. Netplan configuration should NOT be accessible by others.
chmod 600 /etc/netplan/90-private.yaml# 测试配置语法
sudo netplan try --timeout 30
# 按 Enter 接受配置，如果30秒内不按Enter会自动回滚
# 或者直接应用配置
sudo netplan apply不过在RockyLinux上安装就比较痛苦了，可能跟我自己的系统有关系吧。一直提示Error: unknown connection 'enp2s0-static'.。后面用命令修复了（AI给的），IP起来了，但是巨型帧一直设置失效。
# 1. 停止 NetworkManager 临时服务（不影响网络连接）
sudo systemctl stop NetworkManager
# 2. 删除所有旧的配置文件
sudo rm -f /etc/NetworkManager/system-connections/*.nmconnection
# 3. 重启 NetworkManager
sudo systemctl start NetworkManager
# 4. 等待几秒让服务完全启动
sleep 3
# 5. 使用 nmcli 创建连接（这会自动创建正确的配置文件）
sudo nmcli connection add type ethernet \
con-name "enp2s0-internal" \
ifname enp2s0 \
ipv4.method manual \
ipv4.addresses "192.168.100.10/24" \
ipv4.gateway "192.168.100.1" \
ipv4.dns "8.8.8.8,8.8.4.4" \
ipv6.method disabled \
mtu 9000 \
autoconnect yes
# 6. 激活连接
sudo nmcli connection up "enp2s0-internal"
# 7. 验证
nmcli connection show
ip addr show enp2s0ip link show 命令运行提示mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
全部配置完成以后就可以设置NFS挂载了。
Debian Server代码
root@Nicky:~# sudo apt install nfs-kernel-server nfs-common -y
root@Nicky:~# sudo mkdir -p /data
root@Nicky:~# sudo chown -R statd:nogroup /data/
root@Nicky:~# sudo chmod -R 777 /data/
root@Nicky:~# sudo vim /etc/exports配置后按不同的步骤执行
# 格式：共享目录 客户端IP(选项)
/data 192.168.100.4(rw,sync,no_subtree_check,no_root_squash,insecure)
# 或者允许整个网段
# /data 192.168.100.0/24(rw,sync,no_subtree_check,no_root_squash,insecure)
# 选项解释：
# rw: 读写权限
# sync: 同步写入（更安全，建议内网使用async提升性能）
# no_subtree_check: 禁用子树检查，提高性能
# no_root_squash: 允许root用户访问
# insecure: 允许非特权端口连接
# async: 异步写入（性能更好，但有数据丢失风险）
# 重启NFS服务
root@Nicky:~# sudo systemctl restart nfs-kernel-server
# 查看已导出的共享
root@Nicky:~# sudo exportfs -v
# 设置开机自启

# 1. 安装NFS客户端
sudo dnf install nfs-utils -y
# 2. 创建本地挂载点
sudo mkdir -p /mnt/nfs_share
# 3. 测试连接
sudo showmount -e 192.168.100.5

sudo mount -t nfs4 -o rw,hard,intr,rsize=65536,wsize=65536,timeo=600,retrans=2,noatime,nodiratime 192.168.100.5:/shared /mnt/nfs_share
# 5. 验证挂载

创建优化的挂载配置文件
sudo nano /etc/systemd/system/mnt-nfs_share.mount[Unit]

#以上配置where部分需要和文件名一致，不然在自动挂载中会报如下错误： my-nfs.mount’s Where= setting doesn’t match unit name. Refusing.测试结果还不错。有兴趣的可以使用iperf做个测试。结果太长我就不贴了。
