[linux] [java] download jdk1.7 64bit on linux and add to environment path

download jdk1.7 64bit for linux 

這樣是不行的
wget http://download.oracle.com/otn-pub/java/jdk/7u55-b13/jdk-7u55-linux-x64.tar.gz" \
-O jdk-7-linux-x64.tar.gz


要加header
wget --no-cookies \
--no-check-certificate \
--header "Cookie: oraclelicense=accept-securebackup-cookie" \
"http://download.oracle.com/otn-pub/java/jdk/7u55-b13/jdk-7u55-linux-x64.tar.gz" \
-O jdk-7-linux-x64.tar.gz


因為下載頁面有一個需要點選接受的按鈕.


解壓縮:
tar -xzf jdk-7-linux-x64.tar.gz -C /opt/

新增環境變數
export PATH=$PATH:/opt/jdk1.7.0_55/bin

export JAVA_HOME=/opt/jdk1.7.0_55/
