一、开发测试环境搭建与测试
1.1 Linux运行环境的搭建与测试
虽然CentOS已经更新到Stream 9 版本但基于大多数企业和单位多数使用CentOS 7版本作为运行底座7版本也一直在更行维护此实践基于CentOS 7 Mini版本搭建。8和9版本的CentOS系统命令少有差别但主要用到的其实都差不多最大的差别在于系统内核与自带的软件组件和库比较新。如果企业开发部署对兼容性有要求应选择其要求或匹配版本。
1.1.1 CentOS 7 运行环境搭建与测试
下载安装CentOS 7 mini 安装教程网上很多不再赘述
安装镜像下载地址
http://isoredirect.centos.org/centos/7/isos/x86_64/按提示安装完系统后进入系统逐步骤配置。
有的Mini版本默认不带ifconfig命令安装完成后可使用dhclient和 ip add命令查询IP地址信息先让CentOS 连入互联网
[rootlocalhost ~]# dhclient
[rootlocalhost ~]# ip add

[rootlocalhost ~]# 查出本地ip地址为 192.168.2.150 和192.168.2.231本地客户端ping测试一下IP能通即可使用远程管理工具使用SSH命令登入方便命令复制粘贴和整理。
ssh root192.168.2.231出现“Are you sure you want to continue connecting (yes/no/[fingerprint])? ” 时输入“yes”连接CentOS主机
输出信息如下

[rootlocalhost ~]#
安装ifconfig命令
首先让我们找出哪个包提供了ifconfig命令。要完成这项任务输入以下命令
yum provides ifconfig输出
[rootlocalhost ~]# yum provides ifconfig
Failed to set locale, defaulting to C
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile* base: mirrors.ustc.edu.cn* extras: mirrors.ustc.edu.cn* updates: mirrors.ustc.edu.cn

Matched from:
Filename : /usr/sbin/ifconfig[rootlocalhost ~]# 2.就像你在上面的输出中所看到的net-tools包提供了ifconfig命令。因此让我们安装net-tools包来使用ifconfig命令。
yum install net-tools3.现在你就可以像以往一样使用ifconfig命令了。
[rootlocalhost ~]# ifconfig
