centos上一键安装jdk、tomcat脚本

下载jdk

Oracle不允许直接从他们的服务器下载jdk，看这里[http://www.oracle.com/technetwork/java/javase/terms/license/index.html]

所以如果你尝试这样：

wget "http://download.oracle.com/otn-pub/java/jdk/7u4-b20/jdk-7u4-linux-x64.tar.gz"

你将得到一个许可条款的页面，幸运的是,你需要一个cookie可以绕过这个：

Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie

所以,如果你想下载64位的Linux(例如jdk7u4使用wget,Ubuntu),您可以使用:

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/8u60-b27/jdk-8u60-linux-x64.tar.gz"

仅供参考,以下是JDK8的下载项目，其他的可以在oracle官网找到

安装脚本

#!/bin/bash

# 授予此脚本可执行权限(chmod +x install_jdk.sh)
# 在终端执行此脚本开始安装(./文件名)
# 注意：不可有多个版本的jdk包！
#      为了使配置的环境变量生效，安装完成后你应该重新登陆。

以上脚本中下载JDK的方式根据自己需求修改即可。

卸载JDK脚本

#!/bin/bash

echo "正在删除相关文件"
sudo rm -rf /usr/local/java/
wait
echo "删除相关文件成功"

echo "恢复配置文件"
# sudo rm -f /etc/environment
# sudo mv /etc/environment.backup.java /etc/environment
sudo rm /usr/bin/java /usr/bin/javac
sudo rm /etc/alternatives/java /etc/alternatives/javac
mv ~/.bashrc.backup.java ~/.bashrc
echo "恢复配置文件成功"
