Software Installation

1. Software name recognition

[abrt-addon-ccpp]-[2.1.11-19]. [El7]. [X86_64].rpm # #rpm结尾的适用与redhat操作系统

||         ||       || ||

Software name software version software application System 64-bit

2. How to install the software

1.rpm

RPM-IVHNAME.RPM # #安装,-V display procedure,-h specifies the encryption method is hash

-ename # #卸载

-qlname # #查询软件生成文件

-QLPNAME.RPM # #查询软件安装后会生成什么文件

-QA # #查询系统中安装的所有软件名称

-QA |grep Name # #查询软件是否安装

-Q Name # # ....

-QP name.rpm # #查询软件安装包安装后的名字

-QF FileName # #查看filename属于那个安装包

-IVH name.rpm--force # #强制安装

-qi Name # #查看软件信息

-KV name.rpm # #检测软件包是否被篡改

-QP name.rpm--scripts # #检测软件在安装或卸载过程中执行的动作

2.yum

Yum

Top software management tools, the most important function is to solve the dependency relationship of software

Yum can be put into use only if there is a Yum source, and the configuration source points to the file

Server Source Side

1. iso image file matching from the network up-down native system version

Rhel-server-7.1-x86_64-dvd.iso

2. Hang the Rhel-server-7.1-x86_64-dvd.iso to/mnt to access the files in the image

Mount Rhel-server-7.1-x86_64-dvd.iso/mnt

650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M00/90/1D/wKiom1jvNkuDE06hAAAyryMrYd4674.jpg "title=" 36020170413162633508.jpg "alt=" Wkiom1jvnkude06haaayrymryd4674.jpg "/>

3. Configure the native Yum source to point to

rm-fr/etc/yum.repos.d/*

Vim/etc/yum.repos.d/yum.repo

[Server]

name=rhel7.1

Baseurl=file:///mnt

Gpgcheck=0

650) this.width=650; "src=" Https://s1.51cto.com/wyfs02/M00/90/1D/wKiom1jvNmySrbQmAAATN33sjO4276.jpg "title=" 36020170413162710368.jpg "alt=" Wkiom1jvnmysrbqmaaatn33sjo4276.jpg "/>

4. Installing Resource sharing services

Yum Install Httpd-y

Systemctl Stop FIREWLSH-PLUGIN-11.2.202.451-RELEASE.X86_64.RPMLD

Systemctl Disable FIREWALLD

Systemctl Start httpd

Systemctl Enable httpd

5. Create a shared directory and hang it on the image file to a shared directory

mkdir/var/www/html/rhel7.1

Umount/mnt

Mount rhel-server-7.1-x86_64-dvd.iso/var/www/html/rhel7.1

6. Testing

Enter in the browser:/HTTP//native ip/rhel7.1

You can see what's in the image

650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M01/90/1C/wKioL1jvNfTyzuhmAABI46hPsgk990.jpg "title=" 36020170413162437746.jpg "alt=" Wkiol1jvnftyzuhmaabi46hpsgk990.jpg "/>

7. Modify the native Yum source to point to

[Server]

name=rhel7.1

baseurl=file:///var/www/html/rhel7.1

Gpgcheck=0

650) this.width=650; "src=" Https://s1.51cto.com/wyfs02/M00/90/1D/wKiom1jvNgLQvWCDAAAbtmA8r3Q770.jpg "title=" 36020170413162448840.jpg "alt=" Wkiom1jvnglqvwcdaaabtma8r3q770.jpg "/>

8. Boot automatically hangs in ISO

Vim/etc/rc.d/rc.local

Mount rhel-server-7.1-x86_64-dvd.iso/var/www/html/rhel7.1

: Wq

chmod +x/etc/rc.d/rc.local

650) this.width=650; "src=" Https://s2.51cto.com/wyfs02/M02/90/1C/wKioL1jvNheRif47AABNemcKiYQ955.jpg "title=" 36020170413162455720.jpg "alt=" Wkiol1jvnherif47aabnemckiyq955.jpg "/>

9. Building of third-party software repositories

Put all rpm packages in a directory where only the RPM files exist

Createrepo-v/rpm Storage Directory

Vim/etc/yum.repos.d/xxx.repo

[Software]

Name=software

BASEURL=FILE:///RPM Storage Directory

Gpgcheck=0

# # # #client指向端 # #

Vim/etc/yum.repos.d/xxxx.repo # #仓库指向文件位置

[xxxx]# #自定义软件仓库名称

name=xxxx# #自定义软件仓库描述

baseurl=ftp://|http://|file://# #仓库位置

Gpgcheck=0 # #不检测gpgkey

# #gpgkey表示软件的出品logo

Example:

Vim/etc/yum.repos.d/yum.repo

[Server]

name=rhel7.1

baseurl=ftp://172.25.0.254/pub/rhel7.1

Gpgcheck=0

: Wq
