在阿里云服务器安装FastDFS测试fdfs_upload_file出错：Connection refused的解决

将22122和2300端口授权就可以了。
↓

一、配置阿里云的安全组规则

1. 找到实例列表，进入安全组配置
   
2. 进入配置规则
   
3. 点击添加安全组规则
4. 重复【3】，分别添加22122和23000端口
   

二、重启FastDFS的Tracker和Storage

1. 重启

[root@iZm5e1qnvovd6uzsn5cdblZ nginx-1.15.4]# fdfs_upload_file /etc/fdfs/client.conf /usr/local/src/nginx-1.15.4.tar.gz
[2020-03-02 17:34:52] ERROR - file: connection_pool.c, line: 144, connect to server xxx.xxx.xxx.xxx:22122 fail, errno: 111, error info: Connection refused
[root@iZm5e1qnvovd6uzsn5cdblZ nginx-1.15.4]# /etc/init.d/fdfs_trackerd start
Starting fdfs_trackerd (via systemctl):                    [  OK  ]
[root@iZm5e1qnvovd6uzsn5cdblZ nginx-1.15.4]# /etc/init.d/fdfs_storaged start
Starting fdfs_storaged (via systemctl):                    [  OK  ]

2. 查看监听

[root@iZm5e1qnvovd6uzsn5cdblZ nginx-1.15.4]# netstat -unltp|grep fdfs
tcp        0      0 0.0.0.0:23000           0.0.0.0:*               LISTEN      8050/fdfs_storaged  
tcp        0      0 0.0.0.0:22122           0.0.0.0:*               LISTEN      8026/fdfs_trackerd  

3. 再次测试

[root@iZm5e1qnvovd6uzsn5cdblZ nginx-1.15.4]# fdfs_upload_file /etc/fdfs/client.conf /usr/local/src/nginx-1.15.4.tar.gz
group1/M00/00/00/rB-lRF5c02qAYK77AA-itrfn0m4.tar.gz

好了，成功。 ^ _ ^
