Three ways to install programs under Ubuntu

Introduction

In Ubuntu, install the application I know there are three ways, respectively, apt-get,dpkg install Deb and make install Source package three. For each of the following methods, for example.

First, Apt-get method

Installing an application using Apt-get install is one of the most common installation methods, such as I want to install build-essential this software, using the following, he will help me to put all the dependencies are installed together.

sudo apt-get install build-essential

After executing the above command, we can see the information, thefollowing extra packages will is installed: represents all the dependent packages that need to be reinstalled.

The various parameters of Apt-get are given below:

Apt-get Install XXX. If there are parameters, then-d means download only, -f means mandatory installation   
apt-get remove xxx     Uninstall XXX  
apt-get update             Update software information database   
apt-get upgrade         & nbsp; system upgrade   
apt-cache search         Search packages    
Tips: It is recommended that you use the "apt-get Update" command frequently to update your software information database

Apt-get in theory is required to be able to network, but if the local source is created, there is no need for networking, the production of local sources can be consulted: Ubuntu production local source

Second, dpkg installation Deb package

The Ubuntu package format is Deb and the installation method is as follows:

sudo  dpkg-  I.  

Dpkg's detailed use method, there are many online, below a few simple list:

Dpkg-i Package.deb	Install package
Dpkg-r Package	Delete Package
Dpkg-p Package	Delete package (including configuration file)
Dpkg-l Package	List the files associated with the package
Dpkg-l Package	Displays the version of the package
Dpkg–unpack Package.deb	Unpack the contents of the Deb package
dpkg-s keyword	Search for the package content that belongs to
Dpkg-l	List the packages that are currently installed
Dpkg-c Package.deb	List the contents of the Deb package
Dpkg–configure Package	Configuration Package

Third, make install source code installation

If you want to use make installation, then you have to install build-essential this dependency package, the installation method has been mentioned earlier. After the installation is complete, we can install the source code. The source installation can be broadly divided into three steps: (./configure) –> compilation (sudo make) –> installation (sudo make install).

2. Configuration : This is the first step in compiling the source code and is done through the ./configure command. Perform this step to prepare the source code for compilation. Common options are -- prefix=prefix to specify where the program is installed. More options are available through Help -- queries. There are also some programs that do not need to perform this step.
4. Compile : Once configured, you can use make the instructions to execute the source code compilation process immediately. Depending on the specifics of the software, the time required for compiling is different, and all we have to do is to wait patiently and watch it change. Although this step is only a simple instruction, sometimes the problems encountered are very complex. The more frequently encountered scenario is that the program compiles halfway through but does not end satisfactorily. At this point, you need to analyze the error message to find a strategy.
6. Installation : If the compilation is not a problem, then execution sudo make install can install the program into the system.

The following example illustrates the installation of Nagios.

1. Unzip the TAR-ZXF nagios-4.0.2.tar.gz  //2. Enter the directory CD NAGIOS-4.0.2//3. Configuration./configure--prefix=/usr/local/nagios     // 4. Compile make ALL//5. Installing make install && make Install-init && make Install-commandmode && make Install-c Onfig
