Install java 7, tomcat, etc. on CentOS

Hi,

I hope following steps could help you.

Install JAVA:

yum install java-(version)

Select allOpen in new window

where (version) must be a valid version of the JDK.
http://openjdk.java.net/install/index.html
(OR)

cd /usr/local/src
wget http://download.oracle.com/otn-pub/java/jdk/7u2-b13/jdk-7u2-linux-x64.rpm

Select allOpen in new window

(If your OS is 64bit)

wget http://download.oracle.com/otn-pub/java/jdk/7u2-b13/jdk-7u2-linux-i586.rpm

Select allOpen in new window

(If you are running on 32bit)

rpm -ivh jdk-7u2-linux-x64.rpm

Select allOpen in new window

Note:  Read this doc to install Java.
http://docs.oracle.com/javase/7/docs/webnotes/install/linux/linux-jdk.html

To Install Ant:
wget http://apache.osuosl.org//ant/binaries/apache-ant-1.8.2-bin.tar.gz
To install check this URL.
http://ant.apache.org/manual/install.html#getBinary


Install Tomcat 7.x.x:

cd /usr/local/
wget http://apache.cc.uoc.gr/tomcat/tomcat-7/v7.0.23/bin/apache-tomcat-7.0.23.tar.gz
tar -zxvf apache-tomcat-7.0.23.tar.gz
rm apache-tomcat-7.0.23.tar.gz
cd apache-tomcat-7.0.23/bin
./startup.sh

Select allOpen in new window

You can find the version to download from the binary distribution HERE.
http://tomcat.apache.org/download-70.cgi


Next you must install tomcat native by downloading the source from here:
http://tomcat.apache.org/download-native.cgi

cd ~
mkdir installers && cd installers
wget http://apache.cc.uoc.gr//tomcat/tomcat-connectors/native/1.1.22/source/tomcat-native-1.1.22-src.tar.gz
tar -zxvf tomcat-native-1.1.22-src.tar.gz
rm tomcat-native-1.1.22-src.tar.gz
cd tomcat-native-1.1.22-src/jni/native
./configure --with-apr=/usr/bin/apr-1-config --with-java-home=/usr/local/java-1.7.2
 
*java-1.7.2 - your Java SDK installed path
make
make install

Select allOpen in new window

Next open up the catalina.sh (where it is probably located at /usr/share/apache-tomcat-7.0.23/bin/catalina.sh) and put export LD_LIBRARY_PATH="/usr/local/apr/lib" at the start of the file.

Jay, thanks a bunch for providing so detailed info.

I wonder why I must install  tomcat native.

Also,

*java-1.7.2 - your Java SDK installed path

I wonder if something is omitted here. The jdk path in my server is /opt/jdk

What should I will this "*java-1.7.2"?

[root@cld01-01 native]# ./configure --with-apr=/usr/bin/apr-1-config --with-java-home=/opt/jdk1.7.0_02

Tomcat Native Version: 1.1.22
checking for chosen layout... tcnative
checking for APR... configure: error: the --with-apr parameter is incorrect. It must specify an install prefix, a build directory, or an apr-config file.


Jay, as u would see, the --with-apr parameter is incorrect. What is APR? How can I solve this?

Jay, please forgone the above comments. I figured out to install apr by the following command:

 yum install apr-devel openssl-devel

Also, I have followed your suggestions to put the export LD_LIBRARY_PATH="/usr/local/apr/lib" the second line of the catalina.sh.

But I don't know why I should install the tomcat native and how to test if the native has been successfully installed.

Hi,
here is the answer for your question.
Why need Tomcat Native?

Jay,

I followed ur instructions. Now how can I test if tomcat native is there to work.

wsyy,

check the difference between various connectors.(Under "Which connector?" section)
http://www.springsource.com/files/uploads/tomcat/tomcatx-performance-tuning.pdf

APR/Native is the flexible one to use. If you  want to go others for specific reasons then you can proceed.
