现在核心的「双栈访问 + IPv4优先 + 防CC+安全头

现在核心的「双栈访问 + IPv4优先 + 防CC+安全头，在宝塔Nginx主配置文件的

.到宝塔终端执行命令，验证并重启Nginx：

nginx -t
nginx -s reload

1. 监听IPv6 80/443

​

2. IPv4优先访问

​

3. 防CC限流

这个在网站配置文件中

server
{
    listen 80;
    listen [::]:80;
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name swhswl.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/wwwroot/swhswl.com/wordpress;

nginx -t
nginx -s reload
