标签:yum软件管理 yum仓库 linux

基于RPM包构建的软件更新机制。

自动解决软件包安装依赖关系

所有软件包由集中的Yum软件提供

 

软件仓库提供的方式:

本地:file://

FTPHTTPftp://http://

 

Yum配置文件解析:

基本设置:/etc/yum.conf

仓库设置:/etc/yum.repos.d/*.repo

日志文件:/var/log/yum.log

 

Yum缓存目录:

存放下载的软件包,仓库记录等文件

/var/cache/yum/$baserach/$releaserver

 

Yum*.repo文件解析:

[base]  # 定义名称,具有唯一性。

name=CentOS-$releasever - Base  # 软件源描述字符串

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra   # Yum源地址

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

enabled   # 是否使用该频道

gpgcheck=1 # 是否验证待安装的RPM包文件

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 # 用于RPM软件包检验的密钥

 

检查*.repo文件:

[root@node0 ~]# yum repolist

Loaded plugins: fastestmirror, security

Loading mirror speeds from cached hostfile

repo id              repo name                           status                                                    

dvd_                 added from: file:///dvd/          6,575

repolist: 6,575

 

查看软件信息:

yum list 软件名称

[root@node0 ~]# yum list lrzsz

Name and summary matches only, use "search all" for everything.

yum info 软件名称

[root@node0 ~]# yum info lynx

Available Packages

Name        : lynx

Arch        : x86_64

Version     : 2.8.6

Release     : 27.el6

Repo        : dvd_

Summary     : A text-based Web browser

URL         : http://lynx.isc.org/

License     : GPLv2

Description : Lynx is a text-based Web browser. Lynx does not display any images,

            : but it does support frames, tables, and most other HTML tags. One

            : advantage Lynx has over graphical browsers is speed; Lynx starts and

            : exits quickly and swiftly displays web pages.

yum provides 命令绝对路径

安装卸载软件:

 

yum 选项 软件名称

install:安装

update:升级指定软件

remove:卸载指定软件

 

清空Yum缓存:一般用于Yum是否有效

[root@node0 ~]# yum clean all

Loaded plugins: fastestmirror, security

Cleaning repos: dvd_

Cleaning up Everything

Cleaning up list of fastest mirrors

************************************************************************************************

安装软件的时候使用yum进行安装,卸载软件的时候使用rpm命令进行卸载,因为使用yum卸载有可能会卸载其他软件导致系统运行不稳定。

************************************************************************************************

查询安装卸载软件包组:

yum 选项 软件包组名

grouplist:查看软件组列表

groupinfo:查看软件组的说明信息

groupinstall:安装指定软件组

groupupdate:升级指定软件组

groupremove:卸载指定软件组

 

源码编译安装:

源码释放到/src目录,安装到/app目录。

检查gccmake是否安装:

[root@node0 lnmp_soft]# rpm -qa make gcc

make-3.81-20.el6.x86_64

gcc-4.4.7-16.el6.x86_64

创建源码和安装目录:

[root@node0 lnmp_soft]# mkdir /src /app

[root@node0 lnmp_soft]# ll /src /app/

/app/:

total 0

 

/src:

total 0

解压文件:

[root@node0 lnmp_soft]# tar -zxvf ./nginx-1.8.0.tar.gz -C /src

指定编译参数,进行安装:

checking for PCRE library in /opt/local/ ... not found

# 导致编译检查不通过报错,由于缺少pcerpcre-devel导致

./configure: error: the HTTP rewrite module requires the PCRE library.

You can either disable the module by using --without-http_rewrite_module

option, or install the PCRE library into the system, or build the PCRE library

statically from the source with nginx by using --with-pcre=<path> option.

执行一个命令的时候没有找到可能的原因:

[root@node0 test]# mycommand

-bash: mycommand: command not found

1.这个命令对应的软件包没有安装。

2.这个软件对应的命令名称不同。

3.这个命令的路径没有在环境变量中设置。

4.这个命令所在的磁盘没有挂载或者是所在磁盘损坏。

5.这个命令所在位置是LVM分区,启动时LVM失败或者是LVM损坏。
