1 证书和私钥的生成

1.创建服务器证书密钥文件 server.key：
openssl genrsa -des3 -out server.key 2048
输入密码，确认密码，自己随便定义，但是要记住，后面会用到。
2.创建服务器证书的申请文件 server.csr
openssl req -new -key server.key -out server.csr
输出内容为：
Enter pass phrase for root.key: ← 输入前面创建的密码
Country Name (2 letter code) [AU]:CN ← 国家代号，中国输入CN
State or Province Name (full name) [Some-State]:BeiJing ← 省的全名，拼音
Locality Name (eg, city) []:BeiJing ← 市的全名，拼音
Organization Name (eg, company) [Internet Widgits Pty Ltd]:MyCompany Corp. ← 公司英文名
Organizational Unit Name (eg, section) []: ← 可以不输入
Common Name (eg, YOUR name) []: ← 输入域名，如：iot.conet.com
Email Address []:admin@mycompany.com ← 电子邮箱，可随意填
Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password []: ← 可以不输入
An optional company name []: ← 可以不输入
4.备份一份服务器密钥文件
cp server.key server.key.org
5.去除文件口令
openssl rsa -in server.key.org -out server.key
6.生成证书文件server.crt，365=一年
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

在能连接互联网的服务器执行证书生成命令；

server.crt 和 server.key 上传到服务器执行目录下

2 配置证书

server {
       listen            80;
       server_name       localhost;
       rewrite ^(.*)$ https://$host$1 permanent;
    }
# https 配置
server {
   listen       443 ssl;
	server_name  localhost;
    # 证书地址配置
	ssl_certificate      /home/data/nginx/cert/server.crt;
	ssl_certificate_key  /home/data/nginx/cert/server.key;  

	ssl_session_cache    shared:SSL:1m;
	ssl_session_timeout  5m;

	ssl_ciphers  ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
	ssl_prefer_server_ciphers  on;

    # 前端页面配置
	location / {
		root   /home/data/html;
		index  index.html index.htm;
	}
    # 后端接口地址代理
	location /secEvent/ {
		proxy_set_header Host $host;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection "Upgrade";
		proxy_set_header X-Real-IP $remote_addr;
		proxy_pass http://IP:8811/secEvent/;
	}
	location /transerManger/ {
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection "Upgrade";
		proxy_set_header Host $host;
		proxy_set_header X-Real-IP $remote_addr;
		proxy_pass http://IP:8810/transerManger/;
	}
}
