FastDFS的一次报错分析
1、故障描述：配置好fdfs后，测试上传一个/etc/passwd的文件,发现有报错信息（之前已经重启过FastDFS相关的服务过了）
# fdfs_upload_file /etc/fdfs/client.conf /etc/passwd
ERROR - file: tracker_proto.c, line: 48, server: 192.168.1.136:22122, response status 2 != 0
tracker_query_storage fail, error no: 2, error info: No such file or directory
2、检查trackerd.log发现如下报错：
ERROR - file: connection_pool.c, line: 110, connect to 192.168.1.137:22122 fail, errno: 113, error info: No route to host
ERROR - file: tracker_mem.c, line: 4297, get sys files from other trackers fail, errno: 113
ERROR - file: connection_pool.c, line: 110, connect to 192.168.1.137:22122 fail, errno: 113, error info: No route to host
ERROR - file: tracker_mem.c, line: 4297, get sys files from other trackers fail, errno: 113
ERROR - file: tracker_proto.c, line: 48, server: 192.168.1.136:22122, response status 11 != 0
INFO - file: tracker_client_thread.c, line: 310, successfully connect to tracker server 192.168.1.136:22122, as a tracker client, my ip is 192.168.1.136 3、解决方法：
1、关闭防火墙：sudo systemctl stop firewalld.service
2、关闭开机启动：sudo systemctl disable firewalld.service
备注：需要在几个节点上分别执行 4、重新上传：
# fdfs_upload_file /etc/fdfs/client.conf /etc/shells
group1/M00/00/00/wKgBiFcBNwKAM6FxAAAAXzJ-yp83094006
#fdfs_upload_file /etc/fdfs/client.conf /etc/passwd
group1/M00/00/00/wKgBiFcBNCSAP497AAAIfEUcfXc0851118 5、在Docker-01上进行测试：
# dd if=/dev/zero of=/tmp/tmp.iso bs=1M count=512
