最近学会了用 WireGuard 来打洞，在此记录一下以备忘。
概述
cd /etc/wireguard
wg genkey > private && chmod 600 private
wg pubkey < private > public && chmod 600 public将配置文件写在 /etc/wireguard/${name}.conf 中，可全局通过 wg-quick [up/down] ${name} 来进行启停，配置文档详见：Quick Start - WireGuard。
如果需要作为常驻服务，更推荐使用 systemctl [enable/disable/start/stop] wg-quick@${name}.service 来进行管理。
懒人脚本
在服务端，我们执行：
#!/usr/bin/env sh
CONFIG_NAME="wg"
SERVER_PRIVATE_KEY="$(cat private)"
SERVER_INTERNAL_IP="192.168.1.2"
SERVER_PORT="10086"
CLIENT_PUBLIC_KEY="this_is_a_public_key_copy_from_your_client"
CLIENT_INTERNAL_IP="192.168.1.3"
cat << EOF > "/etc/wireguard/${CONFIG_NAME}.conf"
[Interface]
PrivateKey = ${SERVER_PRIVATE_KEY}
Address = ${SERVER_INTERNAL_IP}/24
ListenPort = ${SERVER_PORT}
[Peer]
PublicKey = ${CLIENT_PUBLIC_KEY}
AllowedIPs = ${CLIENT_INTERNAL_IP}/24
PersistentKeepalive = 25
EOF
systemctl enable "wg-quick@${CONFIG_NAME}.service"
systemctl start "wg-quick@${CONFIG_NAME}.service"在客户端，我们执行：
#!/usr/bin/env sh
CONFIG_NAME="wg"
SERVER_PUBLIC_IP="server_public_ip_or_domain"
SERVER_PORT="10086"
SERVER_PUBLIC_KEY="this_is_a_public_key_copy_from_your_server"
SERVER_INTERNAL_IP="192.168.1.2"
CLIENT_PRIVATE_KEY="$(cat private)"
CLIENT_INTERNAL_IP="192.168.1.3"
cat << EOF > "/etc/wireguard/${CONFIG_NAME}.conf"
[Interface]
PrivateKey = ${CLIENT_PRIVATE_KEY}
Address = ${CLIENT_INTERNAL_IP}/24
# aliyun
[Peer]
Endpoint = ${SERVER_PUBLIC_IP}:${SERVER_PORT}
PublicKey = ${SERVER_PUBLIC_KEY}
AllowedIPs = ${SERVER_INTERNAL_IP}/24
PersistentKeepalive = 25
EOF
systemctl enable "wg-quick@${CONFIG_NAME}.service"
systemctl start "wg-quick@${CONFIG_NAME}.service"
