对Linux 系统进行简要介绍，并对其服务器安全防护部署提出具体可操作的解决措施。主要体现在用户权限 配置、系统服务配置、防火墙配置、系统优化和日志管理五个方面。在用户权限配置方面，对用户、密码、注销、权限提出命令策 略；在系统服务配置方面，对主板、蓝牙、网络接口、存储方面提出解决措施；并提出防火墙应尽量保持开启；以及在系统优化配 置方面，对交换分区，网络接口优化管理，IP 标识提出优化管理策略；并对日志管理提出具体连串的命令。希望本文提出的 Linux 服务器安全防护部署能对实际运用操作提供参考和借鉴价值。

This paper briefly introduces the Linux system, and puts forward some specific measures to solve the security of the server. It includes five aspects: user rights configuration, system service configuration, firewall configuration, system optimization and log management. In the user configuration, the order strategies of user, password, logout and permissions are proposed; in the service configuration, the solutions of the motherboard, Bluetooth, network interface and storage are put forward; it is proposed that the firewall should be kept open; in the system optimization, the optimization strategies of the swap partition, management interface network and IP logo are proposed; it puts forward a series of commands in the log management. It is hoped that the Linux server security and deployment discussed in this paper can provide reference for practical operation.
