1.登录阿里云，进管理控制台 - 域名与网站 - 域名
2.选择对应的域名 - ssl证书 - 单域名免费证书
3.填写www或者对应的子域名，确定 - 等待审核通过
4.进入进管理控制台 - 安全(云盾) - CA证书服务 - 下载对应证书
5.ssh连接远程服务器，进入nginx安装目录(/etc/nginx/)，新建cert目录
6.将下载下来的证书文件放到cert目录，一般包括(1526192532557.pem 1526192532557.key)
7.修改nginx配置文件
一、仍需访问http网址的情况：
server {... ???????listen 443 ssl;... ???????ssl_certificate ??/etc/nginx/cert/1526192532557.pem; ???????ssl_certificate_key ?/etc/nginx/cert/1526192532557.key; ???????ssl_session_timeout 5m; ???????ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ???????ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ???????ssl_prefer_server_ciphers on;...}二、不需访问http网址，直接都转到https网址下
server { ???????listen ??????80 default_server; ???????listen ??????[::]:80 default_server; ???????server_name ?_; ???????return 301 https://www.likefun.cn/; ???????root ????????/usr/share/nginx/html; ???????include /etc/nginx/default.d/*.conf; ???????location ~ ^/ { ???????????????proxy_pass http://127.0.0.1:3002; ???????} ???????location ~ ^/qushan/.+ { ???????????????proxy_pass http://127.0.0.1:3002; ???????} ???????error_page 404 /404.html; ???????????location = /40x.html { ???????} ???????error_page 500 502 503 504 /50x.html; ???????????location = /50x.html { ???????}}server { ???????listen ??????443 ssl http2 default_server; ???????listen ??????[::]:443 ssl http2 default_server; ???????server_name ?_; ???????root ????????/usr/share/nginx/html; ???????ssl_certificate ??/etc/nginx/cert/1526192532557.pem; ???????ssl_certificate_key ?/etc/nginx/cert/1526192532557.key; ???????ssl_session_timeout 5m; ???????ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ???????ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ???????ssl_prefer_server_ciphers on; ???????# Load configuration files for the default server block. ???????include /etc/nginx/default.d/*.conf; ???????location ~ ^/ { ???????????????proxy_pass http://127.0.0.1:3002; ???????} ???????location ~ ^/qushan/.+ { ???????????????proxy_pass http://127.0.0.1:3002; ???????} ???????error_page 404 /404.html; ???????????location = /40x.html { ???????} ???????error_page 500 502 503 504 /50x.html; ???????????location = /50x.html { ???????}}阿里云域名免费转ssl，实现https访问
