IP变更导致fdfs文件上传服务不可用解决流程

一、问题：

公司新拉了一条专线，外网IP和内网IP都变更了。导致文件服务器直接扑该了，无法预览也无法上传。我们文件服务器通过docker启动的fastdfs容器。
装个命令提示工具

yun install bash-completion -y

二、排查问题,进去看看fastds里面到底有什么

1、查看fastdfs文件服务器docker容器

[root@file-ser-1-225 3B]# docker ps
CONTAINER ID        IMAGE                COMMAND             CREATED             STATUS              PORTS               NAMES
379036e21744        morunchang/fastdfs   "sh storage.sh"     22 hours ago        Up 22 hours                             storage
348d8b43bc3f        morunchang/fastdfs   "sh tracker.sh"     22 hours ago        Up 22 hours                             tracker

fastdfs文件服务器分为storage和tracker两部分。tracker就是调度器，storage就是执行器。那意思就是远程客户端请求文件服务器就是先连接tracker调度器，调度器将选举出来的storage执行器返回给客户端，客户端再去请求storage执行文件操作的请求。
说明这个fastdfs还是一个设计出来就支持分布式部署的工具。
去hub.docker.com搜一下这个镜像：

https://hub.docker.com/search?context=explore&q=fastdfs

morunchang/fastdfs这个镜像是比较老的了。

点进去看看这个镜像

docker pull morunchang/fastdfs
#Run as a tracker
docker run -d --name tracker --net=host morunchang/fastdfs sh tracker.sh
#Run as a storage server
docker run -d --name storage --net=host -e TRACKER_IP=<your tracker server address>:22122 -e GROUP_NAME=<group name> morunchang/

这里的tracker和group name是需要自定义的，自己改。

docker pull morunchang/fastdfs
#Run as a tracker
docker run -d --name tracker --net=host morunchang/fastdfs sh tracker.sh
#Run as a storage server
docker run -d --name storage --net=host -v /opt/fastdfs/data:/data/fast_data -v /etc/localtime:/etc/localtime -e TRACKER_IP=192.168.101.225:22122 -e GROUP_NAME=group1 morunchang/

[root@file-ser-1-225 3B]# docker logs -f --tail 100 storage

正常情况下内网ip是没有问题的，我这里启动的时候指定了外网ip就无法启动storage。

在搭建的过程中主要出现这几个错误信息：
-----------response status 2 != 0

-----------Transport endpoint is not connected
121.218.45.164:22502这里是我启动容器的时候指定的外网地址，对应到内网的也是22122

正常情况下进入storage容器查看一下执行器是否正常是这样的

fdfs服务器部署时出错：Failed to start fdfs_trackerd.service: Unit fdfs_trackerd.service not found.
解决方案：

sudo /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
sudo /usr/bin/fdfs_storaged /etc/fdfs/storage.conf start

ip更改后fastfds如何更改配置
1.修改/etc/fdfs下client.conf和storaged.conf中的tracker_server的ip地址，更改为你现在的ip地址
2.尝试启动，如果tracker没有启动起来，则去更改【文件库】基地址/tracker/data (就是log日志所在目录的兄弟目录)下的storage_servers_new.dat与storage_sync_timestamp.dat，将2者的ip地址对应即可。
参考了很多博客的解决办法，基本上没有解决，ip更更删除容器重启后重新指定也不太行：
https://blog.csdn.net/xxwwh/article/details/121038817?utm_medium=distribute.pc_relevant.none-task-blog-2_defaultbaidujs_title~default-4-121038817-blog-105245972.pc_relevant_multi_platform_whitelistv1&spm=1001.2101.3001.4242.3&utm_relevant_index=7
排查一下磁盘的目录是否满了，我这里就遇到pool满了的问题
df -h

既然fastdfs有自带的nginx，进去nginx配置里面看看

[root@localhost conf]# cd /usr/local/nginx/conf
[root@localhost conf]# cat nginx.confuser  nobody;
worker_processes  2;error_log  logs/error.log warn;
pid        /var/run/nginx.pid;events {worker_connections  1024;
}

}

include conf.d/storage.conf;
容器里面的数据目录：/var/fdfs/data/

2、自定义docker-compose
最后想通过挂载的方式将配置文件挂载出来，在外网修改。最后发生storage怎么改，容器重启以后都会被还原。

将容器至于同一个网络环境下。查看是否是网络的问题
将之前的docker启动的容器直接删掉。将文件压缩备份一下。

tar cfz fdsdate.tgz /opt/fastdfs

docker-compose安装

docker-compose up -d[root@file-ser-1-225 3B]# docker  ps

最终问题可能出在网络方面。现在预览是完全好的，直接将80端口暴漏出去，内网外网都可以访问。但是tracker-list配置内网地址，在内网服务器上可以访问和上传，配置外网地址就无法上传。

三、最终方案-服务器迁移

直接迁移到阿里云，大概70个G的文件，迁移时间一个下午。
文件服务的地址是拼接域名和文件地址。所以整个目录迁移过去。创建文件桶，创建/group1/M00.将整个挂载出来的文件目录通过阿里云提供的工具cp出去。

[root@file-ser-1-225 home]# cd 111.txt/
[root@file-ser-1-225 111.txt]# touch 111.txt
[root@file-ser-1-225 111.txt]#
[root@file-ser-1-225 111.txt]#
[root@file-ser-1-225 111.txt]# cd ..
[root@file-ser-1-225 home]# ./ossutil64 cp -r 111.txt/ oss://longyanglao/
Succeed: Total num: 1, size: 0. OK num: 1(upload 1 files).average speed 0(byte/s)0.125076(s) elapsed
[root@file-ser-1-225 home]# ./ossutil64 cp -r /opt/fastdfs/data/data oss://longyanglao/group1/M00/
Succeed: Total num: 226393, size: 78,860,068,548. OK num: 226393(upload 160600 files, 65793 directories).                                                           average speed 5975000(byte/s)13196.677786(s) elapsed

如果老的文件域名不能换，直接通过域名绑定的方式，也可以通过原来的域名解析到阿里云的域名，无感知的文件迁移。

老的文件域名配置CNAME，解析到阿里云的外网文件域名地址。

四、经过后期排查

发现是路由器的配置的问题。
