[req]
distinguished_name = req_distinguished_name
req_extensions = v3_req

[req_distinguished_name]
countryName = Country Name (2 letter code)
countryName_default = CH
stateOrProvinceName = State or Province Name (full name)
stateOrProvinceName_default = GD
localityName = Locality Name (eg, city)
localityName_default = ShenZhen
organizationalUnitName  = Organizational Unit Name (eg, section)
organizationalUnitName_default  = organizationalUnitName
commonName = Internet Widgits Ltd
commonName_max  = 64

[ v3_req ]
# Extensions to add to a certificate request
basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names

[alt_names]

# 改成自己的域名
#DNS.1 = kb.example.com
#DNS.2 = helpdesk.example.org
#DNS.3 = systems.example.net

# 改成自己的ip
IP.1 = 172.16.24.143
IP.2 = 172.16.24.85

openssl genrsa -out my_ip.key 2048

openssl req -new -out my_ip.csr -key my_ip.key -config openssl.cnf

openssl x509 -req -days 3650 -in my_ip.csr -signkey my_ip.key -out my_ip.crt -extensions v3_req -extfile openssl.cnf

server {
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;

    ssl_certificate /root/openssl/my_ip.crt;
    ssl_certificate_key /root/openssl/my_ip.key;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_ciphers         HIGH:!aNULL:!MD5;

    ...
}

再配置一个server，将80接口重定向到443

server {
    listen 80;
    listen [::]:80;

    server_name _;

    # 将请求转成https
    rewrite ^(.*)$ https://$host$1 permanent;
}

然后nginx -s reload即可~
