Install jdk1.7 under Linux CentOS 6.5, tomcat7.0 environment configuration __linux

First, jdk1.7 installation instructions

Software: jdk-7-linux-x64.rpm
Download Address: http://www.oracle.com/technetwork/java/javase/downloads/java-se-jdk-7-download-432154.html

Verify the original version of the system

[Root@zck ~]# java-version
java Version "1.6.0_24"
OpenJDK Runtime (Environment IcedTea6) ( rhel-1.45.1.11.1.el6-x86_64)
OpenJDK 64-bit Server VM (build 20.0-b12, Mixed mode)

Further view JDK information:

[Root@zck ~]# Rpm-qa | grep java
tzdata-java-2012c-1.el6.noarch
java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.x86_64

Uninstall OPENJDK and do the following:

[Root@zck ~]# rpm-e--nodeps tzdata-java-2012c-1.el6.noarch [root@zck ~]# rpm-e---nodeps
Java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.x86_64

Installing JDK

Upload the new jdk-7-linux-x64.rpm software to/usr/local/to perform the following actions:

[Root@zck local]# RPM-IVH jdk-7-linux-x64.rpm

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

Verifying installation

Do the following to see if the information is normal:

[Root@zck bin]# java
[root@zck bin]# javac
[root@zck bin]# java-version
java Version "1.7.0"
Java (TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot (TM) 64-bit Server VM (build 21.0-b17, Mixed mode)

Configure Environment variables

I did not configure the JDK environment variables without configuring the environment variables to perform the JAVAC and java–version operations properly after my machine was installed jdk-7-linux-x64.rpm. But for future discomfort, here is still a record of how to configure, the operation is as follows:
modifying system environment variable files

VI +/etc/profile

Append the following content to the file:

java_home=/usr/java/jdk1.7.0
jre_home=/usr/java/jdk1.7.0/jre
path= $PATH: $JAVA _home/bin: $JRE _home/bin
classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar: $JRE _home/lib
export java_home jre_home PATH CLASSPATH

Make the changes take effect

[Root@zck local]# source/etc/profile//   make modification take effect immediately
[Root@zck local]#        echo $PATH   //view PATH value

View System Environment Status

[Root@zck ~]# echo $PATH
/usr/local/cmake/bin:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin :/usr/sbin:/usr/bin:/usr/java/jdk1.7.0/bin:/usr/java/jdk1.7.0/jre/bin:/root/bin

two. tomcat7.0 Installation configuration

Software: apache-tomcat-7.0.29.tar.gz
Download Address: http://tomcat.apache.org/download-70.cgi

Install Tomcat:
Upload the apache-tomcat-7.0.29.tar.gz file to the/usr/local and perform the following actions:
The code is as follows:

[Root@admin local]# cd/usr/local  
[root@admin local]# wget /v7.0.57/bin/apache-tomcat-7.0.57.tar.gz  
[root@admin local]# tar-zxv-f apache-tomcat-7.0.29.tar.gz/Decompression Compression pack  
[root@admin local]# rm-rf apache-tomcat-7.0.29.tar.gz//delete zip pack  
[Root@admin local]# MV apache-tomcat-7.0.29 Tomcat  

Start Tomcat:

[Root@admin ~]#/usr/local/tomcat/bin/startup.sh//start tomcat  
using catalina_base:/usr/local/tomcat  
using Catalina_home:/usr/local/tomcat  
using Catalina_tmpdir:/usr/local/tomcat/temp  
using jre_home:/usr/java/ Jdk1.7.0/jre  

The above information appears to have started successfully.

Firewall open 8080 ports

Add 8080 ports to the firewall configuration and do the following:

[Root@admin ~]# VI +/etc/sysconfig/iptables  

Add the following code:

-A rh-firewall-1-input-m state--state new-m tcp-p TCP--dport 8080-j ACCEPT  

Reboot the firewall:

[Root@admin java]# Service iptables restart

To verify the Tomcat installation run:
Check to see if Tomcat is functioning at the following address:
http://192.168.0.54:8080/
See the Tomcat system interface to indicate that the installation was successful.
Stop Tomcat

[Root@admin ~]#  /usr/local/tomcat/bin/shutdown.sh
