如果觉得速度慢，可以先去wireguard源下载rpm包

wget https://copr-be.cloud.fedoraproject.org/results/jdoss/wireguard/epel-7-x86_64/02151984-wireguard-dkms/wireguard-dkms-1.0.20210424-1.el7.noarch.rpm

第一次启动服务用restart

systemctl restart wg-quick@wg0.service;

后续更改配置后重启用reload

systemctl reload wg-quick@wg0.service;

两端能正常通讯才设置服务开机自启动
