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/;}
