1.編寫installJdkTomcat.sh指令碼

   #!/bin/bash
        
        myDir=`pwd`
        
        rpm -qa | grep jdk > jdk.txt
        
        grep "jdk" $myDir/jdk.txt > /dev/null
        if [ $? -eq 0 ]; then
                echo "Install JDK"
        else
                rpm -ivh jdk-7u21-linux-x64.rpm
                rpm -qa | grep jdk > jdk.txt
        fi
        
        rpm -ql `cat jdk.txt | awk '{print $1}'` | grep /release > jdk2.txt
        
        myJdk=`cat jdk2.txt`
        
        javaHome=${myJdk//release/""}
        
        echo ${javaHome}
        
        grep "JAVA_HOME" /etc/profile > /dev/null
        if [ $? -eq 0 ]; then
                echo "Has JAVA HOME"
        else
                echo "export JAVA_HOME=$javaHome" >> /etc/profile
                echo "export PATH=\$PATH:$javaHome/bin" >> /etc/profile
                source /etc/profile
        fi
     if [ ! -d "$myDir/apache-tomcat-7.0.33" ];then
                unzip -x apache-tomcat-7.0.33.zip
        fi
 

2.修改installJdkTomcat.sh的執行屬性

chmod +x installJdk.sh

3.執行installJdk.sh將安裝Jdk&Tomcat，並配置JDK環境變數，解壓Tomcat
