[Linux learning] setting environment variables in Linux

When installing Java, the environment variable settings are involved. For us, we hope that the environment variable settings will still exist after the system is restarted, the following describes how to set permanent environment variables:

 

1. Enter VI/etc/profile on the terminal

2. Enter the following content at the end of the file (Note: it is a colon, not a semicolon)

Export java_home =/usr/share/jdk1.6.0 _ 14

Export jre_home =/usr/share/jdk1.6.0 _ 14/JRE

Export Path = $ jre_home: $ java_home/bin: $ path

Export classpath =.: $ java_home/lib/dt. jar: $ java_home/lib/tools. Jar

3. log out and log on again.
