Substrate开发之二：配置wss协议、数字证书、nginx

1. 生成证书

1.1 配置文件

在/etc/ssl/下生成一个新配置文件sscert.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

1.2 生成证书

1
openssl req -nodes -x509 -days 365 -keyout ./substrate/domain.key -out ./substrate/domain.crt -config sscert.cnf
1
openssl x509 -in ./substrate/domain.crt -noout -text

2. 配置证书

2.1 nginx配置

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;
}

重启nginx

1
nginx -s reload

2.2 浏览器配置证书

在chrome浏览器设置中搜索证书，管理证书导入domain.crt，大功告成，就可以在https://polkadot.js.org/apps中使用wss连接substrate区块链了。
