Wireguard服务器/客户端配置

wg安装
Centos8

$ sudo yum install elrepo-release epel-release
$ sudo yum install kmod-wireguard wireguard-tools

Centos7

$ sudo yum install epel-release https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm
$ sudo yum install yum-plugin-elrepo
$ sudo yum install kmod-wireguard wireguard-tools

服务器配置

# 生成服务器私钥
wg genkey > privatekey
# 生成服务器公钥
wg pubkey < privatekey > publickey
# 生成口令（每一个peer一个）
wg genpsk > presharedkey

# 服务器配置文件设置
cat /etc/wireguard/wg0.conf
[Interface]
Address = 192.168.8.1/24
PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
ListenPort = 53   # 注意该端口是UDP端口
PrivateKey = 服务器私钥

[Peer]
PublicKey = 客户端公钥
PresharedKey = 口令
AllowedIPs = 192.168.8.10/32

[Peer]
PublicKey = 客户端公钥
PresharedKey = 口令
AllowedIPs = 192.168.8.10/32

若是在Centos7操做，注意跑下yum update（对内核版本有要求）
系统转发注意开启
net.ipv4.ip_forward = 1

开启关闭wg指令：

wg-quick up wg0
wg-quick down wg0

客户端配置文件

[Interface]
PrivateKey = 客户端私钥
Address = 192.168.8.10/32
DNS = 114.114.114.114

[Peer]
PublicKey = 服务器公钥
PresharedKey = 口令
AllowedIPs = 0.0.0.0/0
Endpoint = 服务器IP:服务器端口
PersistentKeepalive = 30
