SSL免费证书申请好了，那么我就来看看nginx监听443端口配置SSL证书吧
如果还没安装nginx请看我另外一篇博文安装nginx教程：https://blog.csdn.net/lc8023xq/article/details/107430072

nginx配置：

http {
    include       mime.types;
    default_type  application/octet-stream;
    gzip on;
    gzip_min_length 1024;
    gzip_types text/css application/x-javascript application/vnd.api+json;
    gzip_disable "MSIE [1-6]\.";
    gzip_comp_level 2;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
	server {
        listen       443 ssl;
        server_name  javakfz.com;
        root   /home/www/discuz/public;
        index  index.php;
		#ssl on;
    ssl_certificate  /opt/install/Nginx_SSL/1_javakfz.com_bundle.pem;
    ssl_certificate_key /opt/install/Nginx_SSL/0_javakfz.com.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;
        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        #location / {
        #    try_files $uri $uri/ /index.php?$query_string;
        #}
        location ~ \.php$ {
                include fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME /home/www/discuz/public$fastcgi_script_name;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
		
   }
   #配置80端口重定向443端口
    server {
        listen 80;
        server_name  javakfz.com;
        rewrite ^(.*)$ https://${server_name}$1 permanent;

    }
}

如果在Nginx配置好SSL相关配置之后报错:
检查配置：/usr/local/nginx/sbin/nginx
报错:nginx: [emerg] unknown directive “ssl” in /usr/local/nginx/conf/nginx.conf:26

以上说明没有安装SSL模块，那么我们需要重新安装相关模块
1.在nginx的安装目录执行
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
2.在nginx的安装目录执行
make

最后
/usr/local/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/nginx/sbin/nginx -s reopen # 重启 Nginx
