1 首先启动Substrate
./target/release/node-template --dev --tmp
输出如下：
2 其次用polkadot.js.org来看
出现ERR_CERT_AUTHORITY_INVALID和ERR_CERT_COMMON_NAME_INVALID错误
3 原因调查
从上面的截图数据，很容易判断出是Web socket over SSL 链接有问题，即wss协议（wss://47.104.136.172:9900）的配置问题。
所以需要配置针对特定IP的self-signed certificate证书。
4 解决方案
4.1 生成新配置文件
在/etc/ssl/下生成一个新配置文件ssert.cnf：
[req]
default_bits = 4096
default_md = sha256
distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no
[req_distinguished_name]
C = US
ST = VA
L = SomeCity
O = MyCompany
OU = MyDivision
CN = 127.0.0.1
[v3_req]
keyUsage = keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
[alt_names]
IP.1 = 127.0.0.1
4.2 生成证书
root@btcpool:/etc/ssl# openssl req -nodes -x509 -days 365 -keyout domain.key -out domain.crt -config sscert.cnf
Generating a RSA private key
...............................................................................................................................................................................................................................................................................................................................................++++
..........................................................................................................................................++++
writing new private key to 'domain.key'
-----
验证一下
root@btcpool:/etc/ssl# ls -al
total 60
drwxr-xr-x 4 root root 4096 Dec 24 10:04 .
drwxr-xr-x 107 root root 4096 Dec 24 00:45 ..
drwxr-xr-x 3 root root 20480 Dec 23 10:54 certs
-rw-r--r-- 1 root root 2013 Dec 24 10:04 domain.crt
-rw------- 1 root root 3268 Dec 24 10:04 domain.key
-rw-r--r-- 1 root root 10998 Nov 13 2019 openssl.cnf
drwx--x--- 2 root ssl-cert 4096 Dec 23 10:51 private
-rw-r--r-- 1 root root 437 Dec 24 09:44 san.cnf
-rw-r--r-- 1 root root 379 Dec 24 10:03 sscert.cnf
可以看到已经生成证书文件：domain.crt和domain.key
4.3 验证一下证书内容
输入下面的命令
root@btcpool:/etc/ssl# openssl x509 -in domain.crt -noout -text
输出如下：

4.4 给nginx服务器配置证书
在/etc/nginx/conf.d/下创建substrate配置文件：
server {
listen 9900 ssl http2; # 将端口转发为9900
ssl on;
location / {
proxy_pass http://localhost:9944/; # 指向本地服务端口
proxy_http_version 1.1;
proxy_read_timeout 120s;
proxy_redirect off;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
ssl_certificate domain.crt;
ssl_certificate_key domain.key;
ssl_session_cache shared:cache_nginx_SSL:1m;
ssl_session_timeout 1440m;
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;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
}
重启nginx
nginx -s reload
这时候，用Chrome访问，还是会出现ERR_CERT_AUTHORITY_INVALID和ERR_CERT_COMMON_NAME_INVALID错误
4.5 配置Chrome浏览器里的证书
点击上面的“Manage certificate”：
点击“Import"，把上面生成的domain.crt导入。
4.6 然后，验证
Hola！！！
