使用root用户linux使用root用户linux压缩命令，由于权限足够大，所以做哪些事都好弄
非root用户，权限低时linux系统怎么样，连yuminstall都无法使用，那如何安装软件呢
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
之后模拟离线安装
2、使用非root用户登入linux系统
# 尝试安装yumdownloader，不行的，需要root权限[nim01@svngit root]$ yum install yumdownloaderLoaded plugins: fastestmirrorYou need to be root to perform this command.# 尝试执行wget命令，不行，没有安装[nim01@svngit root]$ wgetbash: wget: command not found# 尝试安装wget，不行的，需要root权限[nim01@svngit root]$ yum install wgetLoaded plugins: fastestmirrorYou need to be root to perform this command.
将我们下载的wget.***.rpm包，上传到linux系统中
Last login: Wed Dec2 09:44:05 2020[nim01@svngit ~]$ pwd/home/nim01# root已经安装lrzsz了，直接上传[nim01@svngit ~]$ rz[nim01@svngit ~]$ lltotal 548-rw-r--r--. 1 nim01 nim01 560272 Dec22020 wget-1.14-18.el7_6.1.x86_64.rpm
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./etc/wgetrc./usr/bin/wget./usr/share/doc/wget-1.14./usr/share/doc/wget-1.14/AUTHORS./usr/share/doc/wget-1.14/COPYING./usr/share/doc/wget-1.14/MAILING-LIST./usr/share/doc/wget-1.14/NEWS./usr/share/doc/wget-1.14/README./usr/share/doc/wget-1.14/sample.wgetrc./usr/share/info/wget.info.gz./usr/share/locale/be/LC_MESSAGES/wget.mo./usr/share/locale/bg/LC_MESSAGES/wget.mo./usr/share/locale/ca/LC_MESSAGES/wget.mo./usr/share/locale/cs/LC_MESSAGES/wget.mo./usr/share/locale/da/LC_MESSAGES/wget.mo./usr/share/locale/de/LC_MESSAGES/wget.mo./usr/share/locale/el/LC_MESSAGES/wget.mo./usr/share/locale/en_GB/LC_MESSAGES/wget.mo./usr/share/locale/eo/LC_MESSAGES/wget.mo./usr/share/locale/es/LC_MESSAGES/wget.mo./usr/share/locale/et/LC_MESSAGES/wget.mo./usr/share/locale/eu/LC_MESSAGES/wget.mo./usr/share/locale/fi/LC_MESSAGES/wget.mo./usr/share/locale/fr/LC_MESSAGES/wget.mo./usr/share/locale/ga/LC_MESSAGES/wget.mo./usr/share/locale/gl/LC_MESSAGES/wget.mo./usr/share/locale/he/LC_MESSAGES/wget.mo./usr/share/locale/hr/LC_MESSAGES/wget.mo./usr/share/locale/hu/LC_MESSAGES/wget.mo./usr/share/locale/id/LC_MESSAGES/wget.mo./usr/share/locale/it/LC_MESSAGES/wget.mo./usr/share/locale/ja/LC_MESSAGES/wget.mo./usr/share/locale/lt/LC_MESSAGES/wget.mo./usr/share/locale/nb/LC_MESSAGES/wget.mo./usr/share/locale/nl/LC_MESSAGES/wget.mo./usr/share/locale/pl/LC_MESSAGES/wget.mo./usr/share/locale/pt/LC_MESSAGES/wget.mo./usr/share/locale/pt_BR/LC_MESSAGES/wget.mo./usr/share/locale/ro/LC_MESSAGES/wget.mo./usr/share/locale/ru/LC_MESSAGES/wget.mo./usr/share/locale/sk/LC_MESSAGES/wget.mo./usr/share/locale/sl/LC_MESSAGES/wget.mo./usr/share/locale/sr/LC_MESSAGES/wget.mo./usr/share/locale/sv/LC_MESSAGES/wget.mo./usr/share/locale/tr/LC_MESSAGES/wget.mo./usr/share/locale/uk/LC_MESSAGES/wget.mo./usr/share/locale/vi/LC_MESSAGES/wget.mo./usr/share/locale/zh_CN/LC_MESSAGES/wget.mo./usr/share/locale/zh_TW/LC_MESSAGES/wget.mo./usr/share/man/man1/wget.1.gz4030 blocks
查看
# 提取完之后，当前目录多了etc和usr两个目录[nim01@svngit ~]$ lltotal 548drwxrwxr-x. 2 nim01 nim01 20 Dec2 10:13 etcdrwxrwxr-x. 4 nim01 nim01 30 Dec2 10:13 usr-rw-r--r--. 1 nim01 nim01 560272 Dec22020 wget-1.14-18.el7_6.1.x86_64.rpm
查看
# 进入usr/bin目录，可以看到可执行的wget文件[nim01@svngit ~]$ cd usr/[nim01@svngit usr]$ lltotal 0drwxrwxr-x. 2 nim01 nim01 18 Dec2 10:13 bindrwxrwxr-x. 6 nim01 nim01 54 Dec2 10:13 share[nim01@svngit usr]$ cd bin/[nim01@svngit bin]$ lltotal 412-rwxr-xr-x. 1 nim01 nim01 418776 May 162019 wget
4、设置环境变量
在家目录中，直接编辑.bashrc文件，降低可执行程序的路径到系统PATH中
这样linux使用root用户，可以直接执行wget指令了
# .bashrc# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfi# Uncomment the following line if you don't like systemctl's auto-paging feature:# export SYSTEMD_PAGER=# User specific aliases and functionsexport 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 ~]$ wgetwget: missing URLUsage: wget [OPTION]... [URL]...Try `wget --help' for more options.
以上就是如何在非 root 用户权限下安装软件并设置环境变量？的详细内容，更多请关注创想鸟其它相关文章！
