实用脚本----Linux下Jdk和Tomcat自动安装shell脚本总结

sudo su #切换到root权限
mkdir /usr/local/java
cd /usr/local/java

#download jdk 1.7.67
wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u67-b01/jdk-7u67-linux-x64.tar.gz

#extract jdk
tar -xvf jdk-7u67-linux-x64.tar.gz

#set environment
export JAVA_HOME="/usr/local/java/jdk1.7.0_67"
if ! grep "JAVA_HOME=/usr/local/java/jdk1.7.0_67" /etc/environment 
then
    echo "JAVA_HOME=/usr/local/java/jdk1.7.0_67" | sudo tee -a /etc/environment

cd /usr/local/tomcat
wget http://apache.fayea.com/apache-mirror/tomcat/tomcat-7/v7.0.56/bin/apache-tomcat-7.0.56.tar.gz

windows:

1）在系统变量里新建JAVA_HOME变量，变量值为：C:\Java\jdk1.7.0_67（根据自己的安装路径填写）

2）新建classpath变量，变量值为：.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar

3）在path变量（已存在不用新建）添加变量值：%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin（注意变量值之间用“;”隔开）
