JDK
從oracle官網上下載JDK
直接解壓，生成/usr/java/
然後創建/etc/profile.d/java.sh
export JAVA_HOME=/usr/java/jdk1.7.0_67
export PATH=$PATH:$JAVA_HOME/bin
或者
tar xf jdk-7u45-linux-x64.tar.gz
mv jdk1.7.0_45/ /usr/local/jdk
vi /etc/profile
JAVA_HOME=/usr/local/jdk
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export JAVA_HOME PATH CLASSPATH
tomcat
在tomcat.apache.org上下載tomcat
直接解壓，-C /usr/local
做個軟鏈 ln -s
然後創建/etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$PATH:$CATALINA_HOME/bin
或者
tar xf apache-tomcat-8.0.0-RC5.tar.gz
mv apache-tomcat-8.0.0-RC5 /usr/local/tomcat
tomcat安裝好後，在/usr/local/tomcat裏面有以下文件和目錄：
bin conf lib LICENSE logs NOTICE RELEASE-NOTES RUNNING.txt temp webapps work
在webapps裏面有以下5個目錄
docs examples host-manager manager ROOT
<Server>
