要在nginx中配置https，就必须安装ssl模块，也就是: http_ssl_module
进入到nginx的解压目录： /home/software/nginx-1.16.1
新增ssl模块(原来的那些模块需要保留)
./configure \
--prefix=/usr/local/nginx \
--pid-path=/var/run/nginx/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/temp/nginx/client \
--http-proxy-temp-path=/var/temp/nginx/proxy \
--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
--http-scgi-temp-path=/var/temp/nginx/scgi \
--with-http_ssl_module
make
make install
把ssl证书 *.crt 和 私钥 *.key 拷贝到 /usr/local/nginx/conf 目录中。
新增 server 监听 443 端口：
server {
listen 443;
server_name www.imoocdsp.com;
# 开启ssl
ssl on;
# 配置ssl证书
ssl_certificate xxxxx.crt;
# 配置证书秘钥
ssl_certificate_key xxxxx.key;
# ssl会话cache
ssl_session_cache shared:SSL:1m;
# ssl会话超时时间
ssl_session_timeout 5m;
# 配置加密套件，写法遵循 openssl 标准
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
ssl_prefer_server_ciphers on;
