• Shell——查看基础信息脚本

    文章目录

    脚本简介

    1. 基于运维统一脚本中，19、脚本安装下的检查服务器脚本安装
    2. 使用yum安装(yum仓库)，系统版本Centos7

    脚本注解

    1. 该脚本为了快速查看Centos7服务器上的基础配置
    2. 基础配置:OS、CPU、Memory、DISK、Network 的基础配置信息
    3. 脚本在检查磁盘读写是需要安装sysstat,检查网络配置是需要安装net-tools安装包
    4. 脚本自动判断，如果没有安装，则退出脚本，提示需要安装对应的软件包

    安装方式

    cd /usr/local/bin
vim infosystem
...
# 保存退出后，赋予脚本可执行权限
chomd +x infosystem

    1. 脚本存放在/usr/local/bin/目录下，文件名: infosystem
    2. 存放完成后，添加可执行权限

    执行方式

    infosystem

    • 1
    1. 在当前已安装的服务器上的任意路径输入infosystem
    2. 服务器上已安装bash-completion的则可使用tab键进行自动补全
    执行结果
    [root@localhost ~]# infosystem

    脚本内容

    新版本
    1. 新版本新增中文注解，同时可通过脚本变量进行修改，默认中文，可执行修改
    2. 新增CPU使用状态内容
    3. 优化网卡的显示内容，(k8s安装calico生成的虚拟网卡除外)
