Centos installation JDK Tomcat

CentOS 6.5 64-bit

Jdk-8u66-linux-x64.gz

Apache-tomcat-7.0.67.tar.gz

First, I'm using SECURECRT to connect to the server.

#rpm-qa | grep java

See the JDK that is already installed on this machine generally, there will be openjdk

Download OpenJDK

#rpm-E--nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64#rpm-e--nodeps java_cup-0.10k-5.el6.x86_64#rpm-e --nodeps java-1.6.0-openjdk-devel-1.6.0.0-1.66.1.13.0.el6.x86_64#rpm-e--nodeps tzdata-java-2013g-1.el6.noarch# Rpm-e--nodeps java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64#rpm-e--nodeps gcc-java-4.4.7-16.el6.x86_64

Download Sun company JDK I was downloaded locally because I this weak chicken don't know how to get up and down on the server

Uploading to the JDK and Tomcat to the server, I used to build a folder in Windows to store the installation package, so I also built a new folder under Linux storage

This is a problem, where should this folder be built, on the internet to look up the home//is the user's main directory so let's go.

#mkdir/home/software_bak

#rz

And then we move them to the files I've stored in the installation

#mv jdk-8u66-linux-x64.gz Apache-tomcat-7.0.67.tar.gz/home/software_bak

Create a new Java and Tomcat file under/usr

#mkdir/usr/java

#mkdir/usr/tomcat

Move the installation files to the development folder

#mv/home/software_bak Jdk-8u66-linux-x64.gz/usr/java

#mv/home/software_bak Apache-tomcat-7.0.67.tar.gz/usr/tomcat

Install the JDK first

#cd/usr/java

# TAR-ZXVF Jdk-8u66-linux-x64.gz

Configure the environment variable bar

# Vim +/etc/profile (go in and press I then copy the contents in, Last click ESC, enter: Wq return)

# jdk8 Settingsjava_home=/usr/java/jdk1.8.0_66jre_home= $JAVA _home/jrepath= $PATH: $JAVA _home/bin: $JRE _home/ Binclasspath=: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar: $JRE _home/libexport java_home jre_home PATH CLASSPATH

#source/etc/profile

Installing Tomcat

#cd Usr/tomcat

#tar-ZXVF apache-tomcat-7.0.67.tar.gz

I don't know if Tomcat is going to be configuring environment variables. I remember the Windows installation I do not configure I just let go of the firewall port open a few to see if you can access

The first time I got a firewall, I was going to go to the sky and tell you this. Don't add the rule to the last line of the firewall configuration and open the MySQL port.

#vi/etc/sysconfig/iptables

Reboot, take effect

#service iptables Restart

MD, engaged in a half-day, unexpectedly can't open the site, the original is Tomcat port has not changed

#vi Tomcat/apache-tomcat-7.0.67/conf/server.xml

Change 8080 to 80

But I am so distressed. Telnet can't get through. I'm going to the sky. The result is a little cold on the platform, thinking that the original was not started Tomcat, so I came down again

#cd/usr/tomcat/apache-tomcat-7.0.67

#bin/startup.sh

I can open it, too.
