nginx使用openSSL自签生成https相关证书

生成CA私钥

openssl genrsa -out ca.key 2048

生成 CA 根证书 (自签名)

openssl req -new -x509 -days 36500 -key ca.key -out ca.crt -subj "/C=CN/ST=State/L=City/O=Organization/OU=Unit/CN=Root CA"

生成服务端私钥（给 Nginx 用）

openssl genrsa -out server.key 2048

生成服务端证书签名请求，下面ip需修改为域名或部署机器的ip

openssl req -new -key server.key -out server.csr -subj "/C=CN/ST=State/L=City/O=Organization/OU=Unit/CN=192.168.2.129"

使用CA签发服务端证书，可修改签发有效期

openssl x509 -req -days 36500 -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt

生成客户端私钥（给浏览器或其它接入程序使用）

openssl genrsa -out client.key 2048

生成客户端证书签名请求，下面的client_name需修改为接入端身份标识

openssl req -new -key client.key -out client.csr -subj "/C=CN/ST=State/L=City/O=Organization/OU=Unit/CN=client_name"

使用CA签发客户端证书,可修改签发有效期

openssl x509 -req -days 36500 -in client.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out client.crt

打包客户端证书为PKCS12格式(给浏览器或其他接入程序使用)

openssl pkcs12 -export -out client.p12 -inkey client.key -in client.crt -certfile ca.crt
