Linux非root用户安装rpm包_linux 普通用户添加rpm

情况

使用root用户，因为权限足够大，所以做什么事都好弄

非root用户，权限低时，连yum install都没法使用，那怎么安装软件呢

安装rpm包

1、以安装wget工具为例

首先在windows浏览器上下载一个wget的rpm包

http://www.rpmfind.net/linux/centos/7.9.2009/os/x86_64/Packages/wget-1.14-18.el7_6.1.x86_64.rpm

然后模拟离线安装

2、使用非root用户登录linux系统

# 尝试安装yumdownloader，不行的，需要root权限
[nim01@svngit root]$ yum install yumdownloader
Loaded plugins: fastestmirror
You need to be root to perform this command.

# 尝试执行wget命令，不行，没有安装
[nim01@svngit root]$ wget
bash: wget: command not found

# 尝试安装wget，不行的，需要root权限
[nim01@svngit root]$ yum install wget
Loaded plugins: fastestmirror
You need to be root to perform this command.

将我们下载的wget.***.rpm包，上传到linux系统中

3、安装rpm包

提取文件

# 执行下面指令，从安装包中提取文件
[nim01@svngit ~]$ rpm2cpio wget-1.14-18.el7_6.1.x86_64.rpm | cpio -idvm

4、设置环境变量

在家目录中，直接编辑.bashrc文件，增加可执行程序的路径到系统PATH中
这样，可以直接执行wget指令了

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

export PATH=$PATH:$HOME/usr/bin

保存退出后

# 执行source，让修改生效
[nim01@svngit ~]$ source .bashrc
# 执行wget，可正常使用
[nim01@svngit ~]$ wget
wget: missing URL
Usage: wget [OPTION]... [URL]...

Try `wget --help' for more options.
