概述
为方便获取服务器系统及服务相关信息，根据业务实际以及系统相关情况特编写该脚本。
脚本功能
- 可查询服务器主板、BIOS、CPU、内存卡、网卡硬件信息；
- 可查询系统基础信息、SElinux状态、语言编码、启动时间等信息；
- 可查询默认网卡配置信息、外网地址、本地网卡地址等信息；
- 可检查OpenSSH服务版本、运行状态、协议版本、监听端口、信任主机等信息;
- 可查询Firewalld&IPtables防火墙状态、版本、规则信息;
- 可检查JAVA工具部署情况;
- 可检查Sudoers授权信息;
- 可查询UDP&TCP端口监听信息;
- 可查询系统自启动执行命令内容;
- 可查询历史用户登录窗口和时间等信息;
- 可查询最近10个软件安装信息;
- 可查询系统各用户所配置的计划任务;
- 可查询随系统自启动的服务以及当前系统运行的服务;
- 可查询僵尸进程、CPU&内存占用前十进程;
- 可检查SNMP服务运行状态;
- 可检查NTP服务运行状态;
- 可检查Syslog服务运行状态;
- 可检查用户密码过期时间、密码策略;
- 可检查特权用户、空密码用户、相同ID用户、可登录用户列表;
- 可检查磁盘分区、分区大小、可用率等信息;
- 可检查内存使用情况、缓存、交换分区等信息。
