Step 1: Cài đặt JDK:
Có thể download trực tiếp tại oracle sau đó copy lên Server hoặc wget rpm từ oracle.

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u91-b14/jdk-8u91-linux-i586.rpm" |
Export các biến môi trường bên dưới, tùy vào đường dẫn cài đặt Java từ rpm:

export PATH=$PATH:/usr/java/jdk1.8.0_91/bin:/usr/java/jdk1.8.0_91/jre/bin export JAVA_HOME=/usr/java/jdk1.8.0_91 export JRE_HOME=/usr/java/jdk1.8.0_91/jre |
Đối với chkconfig viết file startup như sau:

Change Port của Tomcat
Change tại file:/opt/tomcat/conf/server.xml

<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> |
Restart lại Tomcat để có hiệu quả.
