Linux软件包安装和卸载

linux系统下安装软件包的三种方法：
1.rpm工具：下载软件rpm包安装，类似Windows的exe文件
2.yum工具：类似应用商店，相比rpm安装优势在于更方便快捷，会自动安装依赖包
3.源码包：下载源码包到linux系统中，需要编译器编译安装

rpm工具用法：
rpm包的格式如下图：（zsh为包名，5.0.2为版本号，-31.el7为发布版本号）

[root@localhost Packages]# zsh-5.0.2-31.el7.x86_64.rpm

安装rpm包命令：rpm -ivh 包名

[root@localhost Packages]# rpm -ivh zsh-5.0.2-31.el7.x86_64.rpm 准备中... ################################# [100%] 正在升级/安装... 1:zsh-5.0.2-31.el7 ################################# [100%]

升级rpm包命令：rpm -Uvh 包名

[root@localhost Packages]# rpm -Uvh zsh-5.0.2-31.el7.x86_64.rpm

*当系统中有高版本的zsh包的时候，可以使用rpm -Uvh 升级包

卸载rpm包：rpm -e 包名

[root@localhost Packages]# rpm -e zsh #卸载不需要写包的全名

查询系统已安装的rpm包： rpm -qa

[root@localhost Packages]# rpm -qa

查询指定的包是否安装：rpm -q 包名

[root@localhost Packages]# rpm -q zsh #前文安装zsh包后已卸载所以提示未安装 未安装软件包 zsh [root@localhost Packages]# rpm -q vim-enhanced #已安装的包会列出包的信息 vim-enhanced-7.4.160-6.el7_6.x86_64

查询指定包的详细信息： rpm -qi 包名

[root@localhost Packages]# rpm -qi vim-enhanced Name : vim-enhanced Epoch : 2 Version : 7.4.160 Release : 6.el7_6 Architecture: x86_64 Install Date: 2019年08月28日 星期三 11时22分18秒 Group : Applications/Editors Size : 2296674 License : Vim Signature : RSA/SHA256, 2019年07月01日 星期一 21时34分29秒, Key ID 24c6a8a7f4a80eb5 Source RPM : vim-7.4.160-6.el7_6.src.rpm Build Date : 2019年06月28日 星期五 21时59分48秒 Build Host : x86-02.bsys.centos.org Relocations : (not relocatable) Packager : CentOS BuildSystem <http://bugs.centos.org> Vendor : CentOS URL : http://www.vim.org/ Summary : A version of the VIM editor which includes recent enhancements Description : VIM (VIsual editor iMproved) is an updated and improved version of the vi editor. Vi was the first real screen-based editor for UNIX, and is still very popular. VIM improves on vi by adding new features: multiple windows, multi-level undo, block highlighting and more. The vim-enhanced package contains a version of VIM with extra, recently introduced features like Python and Perl interpreters. Install the vim-enhanced package if you'd like to use a version of the VIM editor which includes recently added enhancements like interpreters for the Python and Perl scripting languages. You'll also need to install the vim-common package.

列出包的安装文件：rpm -ql 包名

[root@localhost Packages]# rpm -ql vim-enhanced /etc/profile.d/vim.csh /etc/profile.d/vim.sh /usr/bin/rvim /usr/bin/vim /usr/bin/vimdiff /usr/bin/vimtutor

查看文件由什么包安装： rpm -qf 文件绝对路径

[root@localhost Packages]# rpm -qf /usr/bin/vimdiff vim-enhanced-7.4.160-6.el7_6.x86_64

yum工具的用法：
yum list ：列出yum仓库中可以安装的rpm包

[root@localhost ~]# yum list

*第三列表示仓库名，带@符号表示已安装

查看yum仓库配置文件：

[root@localhost ~]# ls /etc/yum.repos.d/ CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Sources.repo CentOS-Vault.repo

yum search 包名：搜索yum仓库中的包

[root@localhost ~]# yum search tomcat 已加载插件：fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.huaweicloud.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com =========================================================================== N/S matched: tomcat =========================================================================== tomcat-admin-webapps.noarch : The host-manager and manager web applications for Apache Tomcat tomcat-docs-webapp.noarch : The docs web application for Apache Tomcat tomcat-javadoc.noarch : Javadoc generated documentation for Apache Tomcat tomcat-jsp-2.2-api.noarch : Apache Tomcat JSP API implementation classes tomcat-jsvc.noarch : Apache jsvc wrapper for Apache Tomcat as separate service tomcat-lib.noarch : Libraries needed to run the Tomcat Web container tomcat-servlet-3.0-api.noarch : Apache Tomcat Servlet API implementation classes tomcat-webapps.noarch : The ROOT and examples web applications for Apache Tomcat tomcatjss.noarch : JSS Connector for Apache Tomcat, a JSSE module for Apache Tomcat that uses JSS tomcat.noarch : Apache Servlet/JSP Engine, RI for Servlet 3.0/JSP 2.2 API tomcat-el-2.2-api.noarch : Expression Language v2.2 API

yum list | grep 包名：第二种搜索包的方式，显示信息更简洁

[root@localhost ~]# yum list | grep tomcat tomcat.noarch 7.0.76-9.el7_6 updates tomcat-admin-webapps.noarch 7.0.76-9.el7_6 updates tomcat-docs-webapp.noarch 7.0.76-9.el7_6 updates tomcat-el-2.2-api.noarch 7.0.76-9.el7_6 updates tomcat-javadoc.noarch 7.0.76-9.el7_6 updates tomcat-jsp-2.2-api.noarch 7.0.76-9.el7_6 updates tomcat-jsvc.noarch 7.0.76-9.el7_6 updates tomcat-lib.noarch 7.0.76-9.el7_6 updates tomcat-servlet-3.0-api.noarch 7.0.76-9.el7_6 updates tomcat-webapps.noarch 7.0.76-9.el7_6 updates tomcatjss.noarch 7.2.1-8.el7_6 updates 

yum -y install 包名：安装包

[root@localhost ~]# yum -y install vim-enhanced

yum grouplist：列出可以安装的环境分组和拓展组

[root@localhost ~]# yum grouplist Failed to set locale, defaulting to C Loaded plugins: fastestmirror There is no installed groups file. Maybe run: yum groups mark convert (see man yum) Loading mirror speeds from cached hostfile * base: mirrors.huaweicloud.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Available Environment Groups: Minimal Install Compute Node Infrastructure Server File and Print Server Basic Web Server Virtualization Host Server with GUI GNOME Desktop KDE Plasma Workspaces Development and Creative Workstation Available Groups: Compatibility Libraries Console Internet Tools Development Tools Graphical Administration Tools Legacy UNIX Compatibility Scientific Support Security Tools Smart Card Support System Administration Tools System Management Done

yum -y groupinstall 分组名：安装分组 （分组名有多个单词的情况下加单引号）

[root@localhost ~]# yum -y groupinstall 'Basic Web Server'

yum -y remove 包名：卸载包

[root@localhost ~]# yum -y remove tomcat

yum -y update 包名：更新包

[root@localhost ~]# yum -y update vim-enhancde

yum provides "/*/命令"：查看命令由什么包安装以及安装路径
*当遇到命令名称与包名不一样的情况时，使用yum list | grep 包名可能找不到具体信息，使用yum provides可以根据命令找到包名以及安装路径，比如：pstree命令，pstree命令的包名为psmisc

[root@localhost ~]# yum provides "/*/pstree" 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.huaweicloud.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com psmisc-22.20-15.el7.x86_64 : Utilities for managing processes on your system 源 ：base 匹配来源： 文件名 ：/usr/bin/pstree

yum搭建本地仓库：
挂载带有centos镜像的光盘：

[root@localhost ~]# mount /dev/cdrom /mnt/gp/ mount: /dev/sr0 写保护，将以只读方式挂载

备份yum配置文件：

[root@localhost ~]# cp -r /etc/yum.repos.d/ /etc/yum.repos.d.bak

清空配置文件：

[root@localhost ~]# rm -rf /etc/yum.repos.d/*

新建本地yum仓库配置文件：

[root@localhost ~]# vim /etc/yum.repos.d/yumck.repo

添加以下内容：

[yumck] name=install yumck #自定义描述字符 baseurl=file:///mnt/gp/ #仓库中rpm包的路径 enable=1 #是否可用，改为0改仓库即变为不可用 gpgcheck=0 #是否检测

清除缓存：

[root@localhost ~]# yum clean all 已加载插件：fastestmirror, langpacks 正在清理软件源： yumck Cleaning up list of fastest mirrors Other repos take up 197 M of disk space (use --verbose for details)

查看本地yum仓库中可安装的包：

[root@localhost ~]# yum list

安装测试：

[root@localhost ~]# yum -y install zsh 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile 正在解决依赖关系 --> 正在检查事务 ---> 软件包 zsh.x86_64.0.5.0.2-31.el7 将被 安装 --> 解决依赖关系完成 依赖关系解决 =========================================================================================================================================================================== Package 架构 版本 源 大小 =========================================================================================================================================================================== 正在安装: zsh x86_64 5.0.2-31.el7 yumck 2.4 M 事务概要 =========================================================================================================================================================================== 安装 1 软件包 总下载量：2.4 M 安装大小：5.6 M Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction 正在安装 : zsh-5.0.2-31.el7.x86_64 1/1 验证中 : zsh-5.0.2-31.el7.x86_64 1/1 已安装: zsh.x86_64 0:5.0.2-31.el7 完毕！

查看已安装的包：
*第三列已显示该包来源于本地yum仓库

[root@localhost ~]# yum list |grep zsh zsh.x86_64 5.0.2-31.el7 @yumck 

更换国内yum源：

*centos默认yum源是国外的，有时候安装软件速度很慢，可以更换网易yum源解决
备份系统自带的yum配置文件：/etc/yum.repos.d/CentOS-Base.repo

[root@localhost yum.repos.d]# ls CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Sources.repo CentOS-Vault.repo [root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak

wget下载对应版本的repo文件：http://mirrors.163.com/.help/CentOS7-Base-163.repo

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

或使用curl -O：

[root@localhost yum.repos.d]# curl -O http://mirrors.163.com/.help/CentOS7-Base-163.repo

清除缓存：

[root@localhost yum.repos.d]# yum clean all

查看更换完成的yum仓库rpm包列表：

[root@localhost yum.repos.d]# yum list

安装拓展yum源：

*当更换的国内yum仓库或系统默认yum仓库包不够时，可以添加yum拓展源（由redhat官方提供的yum拓展仓库，包数量更多）
安装拓展源 epel-release：

[root@localhost yum.repos.d]# yum -y install epel-release

查看配置文件：
*安装完成后可以看到目录下增加了epel拓展源（epel.repo、epel-testing.repo）配置文件

[root@localhost yum.repos.d]# ls CentOS7-Base-163.repo CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo epel.repo CentOS-Base.repo.bak CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo epel-testing.repo

查看yum仓库rpm包列表即可显示新增拓展源的rpm包：

[root@localhost yum.repos.d]# yum list 

yum下载rpm包：

*使用yum命令安装软件包时，系统会直接将yum仓库的软件包安装到系统中

yumdownloader 命令：将yum仓库中的rpm包下载到本地不安装

[root@localhost ~]# yumdownloader zsh 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile * epel: hkg.mirror.rackspace.com

查看下载好的包：

[root@localhost ~]# ls #该命令会直接把包下载到当前所在目录 mytest zsh-5.0.2-31.el7.x86_64.rpm 

- -resolve 参数：自动下载相关依赖包
*加上 - - resolve参数在下载目标rpm包时，会检查包的依赖关系并下载先关依赖包

[root@localhost ~]# yumdownloader --resolve zsh 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile * epel: hkg.mirror.rackspace.com --> 正在检查事务 ---> 软件包 zsh.x86_64.0.5.0.2-31.el7 将被 安装 --> 解决依赖关系完成 zsh-5.0.2-31.el7.x86_64.rpm 

- -destdir 参数：指定下载rpm包的存放目录
*如不指定存放目录，rpm包会存放到当前所在目录

[root@localhost ~]# yumdownloader zsh --destdir /root/mytest/ 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile * epel: hkg.mirror.rackspace.com zsh-5.0.2-31.el7.x86_64.rpm | 2.4 MB 00:00:00 [root@localhost ~]# ls /root/mytest/ zsh-5.0.2-31.el7.x86_64.rpm

源码包安装：

*以apache2.2为例，源码包存放路径/usr/local/src/，apache2.2安装路径/usr/local/apache

在安装源码包之前先安装gcc编译器：

*gcc是GNU编译器套件（GNU Compiler Collection），它包括了C、C++、Objective-C、Fortran、Java、Ada、Go语言和 D语言的前端，也包括了这些语言的库（如 libstdc++、libgcj等等）。

[root@localhost src]# yum -y install gcc

进入指定目录下载apache2.2源码包：

[root@localhost ~]# cd /usr/local/src/ [root@localhost src]# wget https://ftp.bit.nl/apache/httpd-2.2.29.tar.gz 

解压apache包：

[root@localhost src]# tar -zxvf httpd-2.2.29.tar.gz 

进入apache源码包目录执行如下命令：（指定安装目录生成makefile文件）

[root@localhost httpd-2.2.29]# ./configure --prefix=/usr/local/apache

查看上一条命令是否执行成功：（0代表成功，非0代表出错，源码安装要多查看命令执行结果避免出错）

[root@localhost httpd-2.2.29]# echo $? 0

编译：

[root@localhost httpd-2.2.29]# make

[root@localhost httpd-2.2.29]# echo $? 0

安装：

[root@localhost httpd-2.2.29]# make install

[root@localhost httpd-2.2.29]# echo $? 0

安装完成：

[root@localhost httpd-2.2.29]# cd /usr/local/apache/ | ls ABOUT_APACHE BuildBin.dsp config.log docs httpd.mak LAYOUT Makefile modules.lo README srclib acinclude.m4 buildconf config.nice emacs-style httpd.spec libhttpd.dep Makefile.in modules.o README.platforms support Apache.dsw buildmark.o config.status httpd include libhttpd.dsp Makefile.win NOTICE README-win32.txt test build CHANGES configure httpd.dep INSTALL libhttpd.mak modules NWGNUmakefile ROADMAP VERSIONING BuildAll.dsp config.layout configure.in httpd.dsp InstallBin.dsp LICENSE modules.c os server
