将fastdfs改为https存取主要有几个步骤：

1. 将/etc/fdfs/目录下的tracker.conf，storage.conf，client.conf 的http.server_port改为443
2. 配置nginx 的SSL模块：https://www.cnblogs.com/ghjbk/p/6744131.html
3. 配置SSL证书 ：https://www.cnblogs.com/grimm/p/5938496.html

一．将/etc/fdfs/目录下的conf配置文件的http.server_port都改为443

1. cd  /etc/fdfs/

#sudo vim tracker.conf 

http.server_port=443

#sudo/usr/bin/fdfs_trackerd  /etc/fdfs/tracker.conf restart  重启

#sudo vim storage.conf

http.server_port=443

#sudo /usr/bin/fdfs_storaged  /etc/fdfs/storage.conf  restart重启

#sudo vim client.conf

http.tracker_server_port=443

查看 Storage 是否成功启动，23000 端口正在被监听，就算 Storage 启动成功。

#sudo netstat -unltp|grep fdfs

tcp        0      0 0.0.0.0:22122           0.0.0.0:*               LISTEN      52750/fdfs_trackerd

tcp        0      0 0.0.0.0:23000           0.0.0.0:*               LISTEN      53017/fdfs_storaged

查看Storage和Tracker是否在通信：

#/usr/bin/fdfs_monitor /etc/fdfs/storage.conf

Storage 1:

id = 192.168.1.108

ip_addr = 192.168.1.108  ACTIVE

http domain =

version = 5.11

join time = 2018-11-13 12:07:21

up time = 2018-11-13 14:28:07

Storage 2:

id = 192.168.1.113

ip_addr = 192.168.1.113  ACTIVE

http domain =

version = 5.11

join time = 2018-11-14 14:14:13

up time = 2018-11-14 14:14:13

total storage = 19067 MB

free storage = 11907 MB

upload priority = 10

store_path_count = 1

subdir_count_per_path = 256

storage_port = 23000

二．配置nginx 的SSL模块

# cd nginx-1.13.12

#/usr/local/nginx/sbin/nginx –V 查看原有的模块

configure arguments: --add-module=../fastdfs-nginx-module-master/src

那么我们的新配置信息就应该这样写：

#./configure--add-module=../fastdfs-nginx-module-master/src --with-http_ssl_module

#make

然后备份原有已安装好的nginx

#cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak

然后将刚刚编译好的nginx覆盖掉原有的nginx（这个时候nginx要停止状态）

停止nginx

#cd /usr/local/nginx/sbin/

#sudo ./nginx -s stop

# cd nginx-1.13.12

覆盖掉原有的nginx

# sudo cp ./objs/nginx /usr/local/nginx/sbin/

然后启动nginx，仍可以通过命令查看是否已经加入成功

# cd /usr/local/nginx/sbin/

#sudo ./nginx

仍可以通过命令查看是否已经加入成功

#/usr/local/nginx/sbin/nginx -V

二．配置SSL证书https://www.cnblogs.com/grimm/p/5938496.html

按照上面链接生成证书文件后配置nginx

# sudo vim /usr/local/nginx/conf/nginx.conf

配置：

# HTTPS server

    server {

       listen       443 ssl;

        server_name  localhost;

        ssl_certificate      /usr/local/nginx/conf/33iq.crt;

        ssl_certificate_key  /usr/local/nginx/conf/33iq_nopass.key;

        ssl on;

        #ssl_session_cache    shared:SSL:1m;

        #ssl_session_timeout  5m;

        #ssl_ciphers  HIGH:!aNULL:!MD5;

       # ssl_prefer_server_ciphers  on;

        location / {

            root   html;

            index  index.html index.htm;

        }

        location ~/group([0-9])/M00 {

             ngx_fastdfs_module;

       }

}

重启nginx

# cd /usr/local/nginx/sbin/

#sudo ./nginx -s reload

配置完成后可以测试使用https存取文件

Java fastdfs 工具类要该端口位443

fastdfs.http_tracker_http_port=433
