Install JDK and tomcat on centos

Recently, the company's internal servers were built using the lamp environment, but Tomcat access was required, while I used the yum installation when setting up the environment, if you are too troublesome, you can go to the yum installation of Apache + PHP + MySQL + Tomcat article. Of course, I compile and install Tomcat after the yum lamp environment, which is equivalent to letting Tomcat run separately. let's take a look at the tutorial.

System: centos 5.5
Software: apache-tomcat-7.0.26.tar.gz jdk-7u3-linux-i586.rpm required
I. preparations:

(1) install centos with minimal installation.

(2) introduce the 163 source.

Wget-P/etc/yum. Repos. d/http://mirrors.163.com/.help/CentOS5-Base-163.repo
(3) install common compilers and tools using yum

Yum-y install GCC gcc-C ++ Autoconf libjpeg-devel libpng-devel FreeType-devel libxml2 libxml2-devel zlib-devel glibc-devel glib2 glib2-devel Bzip2 bzip2-devel ncurses- devel curl-devel Vim ntsysv

2. Go to the official website to download JDK on the Linux platform.

Address: http://www.oracle.com/technetwork/java/javase/downloads/jdk-7u3-download-1501626.html

3. Download tomcat.

Address: http://labs.mop.com/apache-mirror/tomcat/tomcat-7/v7.0.26/bin/apache-tomcat-7.0.26.tar.gz

4. Install software

(1) install JDK: # rpm-IVH jdk-7u3-linux-i586.rpm

Install JDK in the/usr/Java directory.
(2) unzip and install Tomcat: # tar zxf apache-tomcat-7.0.26.tar.gz

5. Configure environment variables:
# Vi/etc/profile

(1) Add at the end of the file

Export java_home =/usr/Java/jdk1.7.0 _ 03
Export jre_home =/usr/Java/jdk1.7.0 _ 03/JRE
Export classpath =.: $ java_home/lib/dt. jar: $ java_home/lib/tools. Jar
Export maid =/usr/local/Apache-Tomcat-7.0.26
Export catalina_home =/usr/local/Apache-Tomcat-7.0.26
Export Path = $ path:/sbin:/bin:/usr/sbin:/usr/bin:/usr/x11r6/bin: $ java_home/bin
(2) Use the following command to make the configuration take effect and view the JDK version.

# Source/etc/profile
# Java-version

6. Configure Tomcat

(1) Add tomcat to start automatically

# Echo "/usr/local/Apache-Tomcat-7.0.26/bin/startup. Sh">/etc/rc. Local

(2) Enable the firewall to open Tomcat ports

Iptables-A RH-Firewall-1-INPUT-M state -- state new-m tcp-p tcp -- dport 8080-J accept
Service iptables save
Service iptables restart

VII. Test

# Cd/usr/local/Apache-Tomcat-7.0.26/bin/
# Chmod 777 *.*
#./Startup. Sh

Open the browser: http: // ip: 8080
