Substrate节点wss配置

申请ssl

ssl免费申请网站

将crt文件和key文件，复制粘贴到节点服务器上。

sudo vim /etc/ssl/certs/nginx-selfsigned.crt
sudo vim /etc/ssl/private/nginx-selfsigned.key
//分配把crt文件和key文件复制粘贴上去
sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

配置nginx

节点服务器上配置：

sudo apt-get install nginx
sudo vim /etc/nginx/nginx.conf 

在 ssl_prefer_server_ciphers on;后面添加下面内容：

server {

        server_name polka.listen.io;


        root /var/www/html;
        index index.html;

        location / {
                try_files $uri $uri/ =404;

                proxy_pass http://localhost:9944;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
        }

        listen [::]:443 ssl ipv6only=on;
        listen 443 ssl;
        ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
        ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;

        ssl_session_cache shared:cache_nginx_SSL:1m;
        ssl_session_timeout 1440m;

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;

        ssl_ciphers "ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS";

        ssl_dhparam /etc/ssl/certs/dhparam.pem;

}

server_name 是域名，设置好自己的域名。

上面的9944端口是节点的外部访问端口，可以设置。

重启nginx

sudo service nginx restart
