LinuxPackage installation method:

1.RpmPackage Installation

2.Yum(Solves dependencies and facilitates software package upgrades)

3.Source code compilation and installation

 

I,RpmPackage management:

Redhat package management

 Example:Sudo-1.7.2pl-5.el5.i386.rpm

Software name, version number, release number, hardware platform

 

Sudo is the default software package for all linux systems.

Rpm package creation encapsulates the compiled execution program of the source code package into the rpm structure. when you install the rpm package, the third step of the source code package installation is actually executed, is to copy the execution program to the corresponding directory.

 

RpmPath ProblemsMost rpm packages do not allow you to change their installation directory. by default, the installation directory is set. It is not like windows registry, and linux uninstallation will automatically uninstall and clean.

1.InstallRpmPackage

Rpm-ivh vsftpd-2.0.5-16.el5_4.1.i386.rpm

I install v installation process information

Overwrite installationRpm-ivh vsftpd-2.0.5-16.el5_4.1.i386.rpm -- replacepkgs

File conflictAn older version of the software -- replacefiles

To solve the dependency-- NodeppsDependency is not considered and cannot be used successfully in most cases.

 

 

2.View all installedRpmPackage

Rpm-qa

Rpm-qa | grep vsftp

3. vsftpInstall many files and store them in different directories under the root directory.

Rpm-SQL vsftpd-2.0.5-16.el5_4.1

4.Which of the following is the reverse query object?RpmThe software package is installed

Rpm-qf/etc/vsftpd. conf

5.View an uninstalledRpmWhat files may be installed after the package

Rpm-qlp vsftpd-2.0.5-16.el5_4.1.i386.rpm

6.UninstallRpmPackage

Rpm e vsftpd-2.0.5-16.el5_4.1

Rpm-e -- nodeps samba forced uninstall, ignore dependencies. No longer. Not recommended

7. upgrade the software package

Rpm-Uvh software package

 

II,RpmPackage installed in three core files:

1.Applications4

/Usr/sbin/vsftpd

# Execution program

2.Configuration file

/Etc/vsftpd. conf

# A file to be read before the application starts and then loaded to the process List

3.Service script

/Etc/rc. d/init. d/vsftpd

# Better control the application to read the configuration file and load it to the process List

 

III,Run scripts:

 

1. corresponding path

./Vsftpd restart

2. absolute path

/Etc/rc. d/init. d/vsftpd restart

3. run the service

Service vsftpd restart

 

IV. attach a CD:

1.Put the CD in the optical drive

2.Check whether the optical drive is powered on.

3.Attach a CD/Media

Mount/dev/cdrom/media

4.How to check whether the mounting is successful

Df-Th

5.Enable automatic mounting of the disc/MediaLower

Vi/etc/fstab

/Dev/cdrom/media iso9660 defaults 0 0

V. SolutionRpmDependency problems:

YumTool managementRpmPackage 

All software packages areCentosSubdirectory

1.Attach a CD(Start)

2.Change Software sourceCd/etc/yum. repos. d/

Mv CentOS-Base.repo CentOS-Base.repo.bak

Software Management "src =" http://s1.sinaimg.cn/bmiddle/66ac0939g7b996b7de460&690 "/>

Suffix sensitiveSo CentOS-Base.repo change plus. bak.

3.Modify the disc source

Vi CentOS-Media.repo

C5-media

Name = CentOS-$ releasever-Media

Baseurl = file: // media

# Disk Mount destination

Gpgcheck = 0

# Go to the official website to update the signature and close it.

Enabled = 1

# Enable the CD source

Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

4.PassYumInstallRpmSoftware

Yum-y install vsftpd *

5.InstallLampEnvironment

Yum-y install httpd * mysql * php *

6.UseYumHow to uninstallRpmPackage

Yum-y remove httpd * mysql * php *

7.Force deleteRpmPackage

Rpm-e httpd-1.3.8 -- nodeps

# Nodeps truncation dependency

8.Force install oneRpmPackage Software

Rpm-ivh mysql-server-5.0.77-4.el5_4.2.i386.rpm -- force -- nodeps

Detect and upgrade yum check-update software name

Upgrade yum update

Query yum list by software package

Package information yum info

Uninstall yum remove

Help yum-help

Determine if the software is installed with rpm-q

VI,Install the source code package (compatible):

Tar.gz tar.bz2

Tar zxf Extract

1.Generate configuration file

./Configure -- prefix =/usr/local/apache2/

 

Collect system information -- prefix to specify the installation directory. There is no special uninstall command. Generally placed in usr/local

Gcc is required to be installed with yum

2.Compile

Make

3.Install

Make install

4. cd/usr/local/apache2/

1) applications

/Usr/local/apache2/bin/httpd

2) service script

/Usr/local/apache2/bin/apachectl

3) configuration file

/Usr/local/apache2/conf/httpd. conf

5.Start source code installationApache

/Usr/local/apache2/bin/apachectl restart

6.View processes

Ps-ef | grep httpd

7.How to installApacheAuto Start

Vi/etc/rc. d/rc. local

/Usr/local/apache2/bin/apachectl restart (ctl control)

 

VII,Script installation Just run. shThe script can (Similar to windows)
