Specify the installation path for the rpm package

Specify the installation path for the rpm package

The rpm package usually has a default installation path. How do you change the default path? Of course. Let's take a look at the example below.
For example, when JDK (Java Development Kit) or JRE (Java Runtime Environment) is installed, the default installation path of the RedHat package file is/usr/java. What if you want to install it in another path, such as the/home/java directory?
1. First, view the rpm package details

Summary: Java (TM) Platform Standard Edition Development Kit
Description:
The Java Platform Standard Edition Development Kit (JDK) includes des both
The runtime environment (Java virtual machine, the Java platform classes
And supporting files) and development tools (compilers, debuggers,
Tool libraries and other tools ).

The JDK is a development environment for building applications, applets
And components that can be deployed with the Java Platform Standard
Edition Runtime Environment.

This JDK is installed in/usr/java by default.

 

In this way, we can set the parameters so that JDK can be installed in the directory you specified.

Parameter description:
Badreloc forces the file to be installed wherever you want.
Relocate only installs the files that should be installed in the oldpath to newpath, so as to install some files to other paths, rather than replacing all the files in this package.
But neither prefix nor relocate can really be used, because some packages or files are not allowed to be mounted to other paths, such as oracleasm-support-2.1.8-1.el6.x86_64.rpm

Not relocatable cannot be relocated, and the installation directory cannot be modified. Only the -- prefix parameter is removed.

The JAVA version is not displayed because the environment variable has not been modified.
Next, modify the JAVA environment variables.
[Root @ bkjia jdk1.6.0 _ 43] # vi/etc/profile
JAVA_HOME =/home/java/jdk1.6.0 _ 43
PATH = $ JAVA_HOME/bin: $ PATH
CLASSPATH =.: $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jar
Export JAVA_HOME
Export PATH
Export CLASSPATH
"/Etc/profile" 85L, 1961C written

[Root @ bkjia jdk1.6.0 _ 43] # source/etc/profile
Make environment variables take effect.
Check that the JAVA version number is displayed.
[Root @ bkjia jdk1.6.0 _ 43] # java-version
Java version "1.6.0 _ 43"
Java (TM) SE Runtime Environment (build 1.6.0 _ 43-b01)
Java HotSpot (TM) 64-Bit Server VM (build pipeline 14-b01, mixed mode)

 

Add:
When installing JDK, you need to check whether the original system has other JAVA version numbers. if the version numbers are inconsistent with the ones you want to install, uninstall them and install them again.
[Root @ bkjia ~] # Java-version
Java version "1.7.0 _ 45"
