我已经在Alpine Linux 3.16.2上配置了 Wireguard VPN 。手动服务器和客户端配置工作正常。

uname -mrs
# Linux 5.15.60-0-virt aarch64

ip link add dev wg0 type wireguard
ip address add dev wg0 10.0.0.4/8
wg setconf wg0 /etc/wireguard/wg0.conf
ip link set up dev wg0
wg
# interface: wg0
#   public key: 9nEynT6g.....
#   private key: (hidden)
#   listening port: 31194
# peer: A2zDuhbX6....
#   allowed ips: 10.0.0.5/32

但是当我重新启动系统设备 wg0 消失。如何做到持久？

我按照Alpine Linux 设置 WireGuard VPN 服务器的说明进行操作，但它似乎有点过时了。

在向 /etc/network/interfaces 添加接口时，我遇到了以下问题。他们不会直接向该文件添加新条目，因为NOTE: /sbin/assemble-interfaces rewrites this file. Edit files in /etc/network/interfaces.d/ to persist any customizations.

如果我添加带有接口描述的新配置文件，它不会在重新启动后加载：

nano /etc/network/interfaces.d/wg0

的内容/etc/network/interfaces.d/wg0

auto wg0
iface wg0 inet static
    address 10.0.0.4/8
    gateway 10.0.0.1
    pre-up ip link add dev wg0 type wireguard
    pre-up wg setconf wg0 /etc/wireguard/wg0.conf
    post-down ip link delete wg0

手动配置正在运行。我可以建立从远程客户端到服务器的 VPN 连接，使用私有地址 10.0.0.4 到服务器的 ssh 并访问 Internet。那么如何在 Alpine Linux 3.16.2] 1上将此接口配置为启动时启动？

我需要12288为QEMU/KVM虚拟机保留大页面。

我按照指南通过3 个简单的步骤在 RHEL/CentOS 7/8 中配置大页面，但看起来在 CentOS Stream 9 中配置文件/etc/sysctl.conf不再用于手动编辑。

grep -i huge /proc/meminfo
AnonHugePages:   1986560 kB
ShmemHugePages:        0 kB
FileHugePages:         0 kB
HugePages_Total:       0
HugePages_Free:        0
HugePages_Rsvd:        0
HugePages_Surp:        0
Hugepagesize:       2048 kB
Hugetlb:               0 kB

当我尝试修改文件nano /etc/sysctl.conf 时，它显示此设置移动到另一个地方

# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).

CentOS Stream 9 中大页面配置的正确方法是什么？
