背景介绍
在于同学联机的过程中，由于各种网络的原因，导致p2p联机方式不是很稳定，有时候ping值能达到25000以上，所以考虑在服务器上建立七日杀server服务。参考链接：linux云服务搭建七日杀服务器 - Shiraka - 博客园 (cnblogs.com)以及官方文档7 Days to Die Dedicated Server - Valve Developer Community (valvesoftware.com)。
配置介绍
使用的服务器配置：腾讯云轻量应用服务器2核4GB（可以考虑再加2GB的虚拟内存）6M带宽Debain11操作系统，保证有18GB以上的空闲磁盘空间。应该注意的是，需要在腾讯云管理面板的安全组中开放8080,26900,26901,26902等端口，具体情况参考官方文档。因为使用steamcmd需要重新注册系统用户等，所以使用docker，docker的安装方法在此不再赘述。
具体操作
运行容器
使用SSH等链接服务器，并且使用root用户运行docker服务，不赘述。拉取官方steamcmd镜像 docker pull cm2network/steamcmd。运行该镜像的容器，注意使用-v和-p等命令挂载数据卷以及映射端口，容器下的/Steam为游戏数据目录。参考命令docker run -d -it -p 8080:8080 -p 8081:8081 -p 8082:8082 -p 26900:26900 -p 26901:26901 -p 26902:26902 cm2network/steamcmd。
登录
使用docker attach 容器ID进入容器之后，可以看到使用的用户是叫steam，现在需要用当前目录下的steamcmd.sh登录，使用命令./steamcmd.sh。之后可以选择用自己的steam账号登录，或者直接用匿名账号登录login anonymous。此时steam会更新。
下载
使用app_update 294420 validate安装七日杀的server版本，需要等待一定时间。安装完成之后可以再运行一次命令验证是否安装完全。
启动
进入到容器的~/Steam/steamapps/common/7 Days to Die Dedicated Server目录下（默认路径）使用命令./st artserver.sh -configfile=serverconfig.xml可以运行默认配置的服务器，参考图片 (我这里使用了tmux，但是实际上使用了docker的话是不用使用tmux的）此时就已经运行了游戏，可以在七日杀客户端使用ip进行链接
配置文件介绍
参考上述链接以及我的笔记Linux/docker.md · masaikk/interviewAccess - Gitee.com 下面附上我的配置文件
