  Installation under Linux to deploy Java
  Add Date : 2016-04-14      
  Java 6 installed small portion (for novice)

1, download packages

# Wget http://download.Oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz?AuthParam=1441937568_6752e90a2aa70be3cf8baa0b8905125c
Change the name of the software, I do not know why the name wget downloaded quite a mess

# Mv jdk-7u79-linux-x64.tar.gz? AuthParam = 1441937568_6752e90a2aa70be3cf8baa0b8905125c /root/jdk-7u79-linux-x64.tar.gz
# Cd
2, unzip the file jdk

# Tar zxf jdk-7u79-linux-x64.gz -C / data /
3. Create a soft link

# Ln -s /data/jdk1.7.0_79 / usr / local / java
4, edit the environment variables (Enter: $ Locate the last line of the file, and then perform the final editing o edge in the paper)

# Vim / etc / profile
1 # ------------------------------ JAVA ----------------- ------------- #
2 export JAVA_HOME = / usr / local / java
3 export PATH = $ JAVA_HOME / bin: $ PATH
4 export CLASSPATH =:. $ JAVA_HOME / lib / dt.jar: $ JAVA_HOME / lib / tools.jar
5, so java environment variables to take effect

# Source / etc / profile
6. Verify java installed successfully (This command returns the java version information)

# Java -version
1 java version "1.7.0_79"
