我没有为每一个新的Java版本都使用一个新的链接或更改现有的脚本，而是寻找一种更通用的方法来自动下载所需的Java包，然后通过yum localinstall ${JAVA_ENVIRONMENT}-${JAVA_VERSION}-linux-x64.rpm进行安装。

我使用了一种类似于手动/用户操作的简单方法来查找包并下载它。我也非常确定，通过使用其他工具(如egrep、awk等)，人们会找到一种更优雅的方式来完成它。，所以这里留一个例子:

#!/bin/bash

### Proxy settings
# If there is a company proxy 

PROXY="my.proxy.local:8080"
PROXY_TYPE="--proxy-ntlm" # or leave empty with ""
USER="user"
PASS='pass'

### Find out the links to JRE and JDK 
# To do so, got to the page http://www.oracle.com/technetwork/java/javase/downloads/

BASE_URL="technetwork/java/javase/downloads"

# Put the whole page into a single string/line

BASE_URL_OUTPUT="$(curl -s -k ${PROXY_TYPE} -x "http://${USER}:${PASS}@${PROXY}" -L0 http://www.oracle.com/${BASE_URL}/)"

# Define the environments to download 

JAVA_ENVIRONMENTS=("JRE" "JDK") # ! yet "SERVER-JRE"

for JAVA_ENVIRONMENT in "${JAVA_ENVIRONMENTS[@]}"
do

echo
echo "JAVA_ENVIRONMENT="$JAVA_ENVIRONMENT
echo

for (( JAVA_BASE_VERSION = 8; JAVA_BASE_VERSION <= 10; JAVA_BASE_VERSION += 2 ))  
do

echo "JAVA_BASE_VERSION="$JAVA_BASE_VERSION

### "Read the page"
# and follow the links for the package interested in 

DOWNLOAD_SITE="$(echo $BASE_URL_OUTPUT | grep -m 1 -io "${JAVA_ENVIRONMENT}${JAVA_BASE_VERSION}-downloads-[0-9]*.html" -- | tail -1)"
echo "DOWNLOAD_SITE="$DOWNLOAD_SITE

### Gather the necessary download links
# To do so, following the link to the download site
# reading and accept the license 
# 
# ... the greedy regular expression is to address the different syntax of the links
# and already prepared for OR .gz files 

DOWNLOAD_LINK_OUTPUT="$(curl -s -k ${PROXY_TYPE} -x "http://${USER}:${PASS}@${PROXY}" -L -j -H "Cookie: oraclelicense=accept-securebackup-cookie" http://www.oracle.com/${BASE_URL}/${DOWNLOAD_SITE} |  grep -io "filepath.*${JAVA_ENVIRONMENT}-[${JAVA_BASE_VERSION}].*linux[-_]x64[._].*\(rpm\)" -- | cut -d '"' -f 3 | tail -1)"

# and echo out the link

echo "DOWNLOAD_LINK_OUTPUT="$DOWNLOAD_LINK_OUTPUT

done

done

由于下载链接现已可用，您可以进一步使用wget或curl。

我已经为我的gentoo盒子制作了一个jdk-download脚本(特定于tar.gz)。不需要像其他类似的脚本那样更新，尝试“强制”下载您想要的任何版本的最新版本。

使用

jdk-download< <version> <platform> [<build>]

* <version> - Something like "8u40"
* <platform> - Usually i586 or x64
* <build> - The internal build number used by oracle, to avoid guessing and trying to download starting from 99 to 1 (build 0, really?!!)

下面是如何获得命令自己。 这适用于任何版本:

Access packages page here: https://www.oracle.com/java/technologies/javase-jdk11-downloads.html Click the download link for your desired package Check the box indicating that you have "reviewed and accept..." Right-click & Copy the link address from the button Paste into a text editor and then copy everything AFTER 'nexturl=', beginning with 'https://' Update the download URL in this command and you should be good to go: wget --no-check-certificate -c --header "Cookie: oraclelicense=accept-securebackup-cookie" https://download.oracle.com/otn/java/jdk/11.0.6+8/90eb79fb590d45c8971362673c5ab495/jdk-11.0.6_linux-x64_bin.tar.gz

为了进一步解释wget，——no-check-certificate应该足够清楚，但是通过使用浏览器中的Developer Tools Network选项卡可以发现头部内容(对于任何调用)。开发人员工具功能强大，非常值得花时间学习。 享受。

你应该试试:

wget \
        --no-cookies \
        --header "Cookie: oraclelicense=accept-securebackup-cookie" \
        http://download.oracle.com/otn-pub/java/jdk/8u172-b11/a58eab1ec242421181065cdc37240b08/jdk-8u172-linux-x64.tar.gz \
        -O java.tar.gz

以上所有内容似乎都假设您知道最新Java RPM的URL……

Oracle提供了到每个Java版本最新更新的持久链接 https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=397248601136938&id=1414485.1 -尽管您需要创建/登录到Oracle支持帐户。*否则，您只能访问每个Java版本的最后一次“公开”更新，例如1.6_u45(2013年3月;最新更新为u65, 2013年10月)*

一旦你知道了持久链接，你应该能够将其解析为真正的下载; 以下对我有用，尽管我还不知道“aru”引用是否发生了变化。

ME=<myOracleID>
PW=<myOraclePW>
PATCH_FILE=p13079846_17000_Linux-x86-64.zip

echo "Get real URL from the persistent link"

wget -o getrealurl.out --no-cookies --no-check-certificate --user=$ME \
--password=$PW --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com" \

REALURL=`grep "^--" getrealurl.out |tail -1 |sed -e 's/.*http/http/'`
wget -O $PATCH_FILE $REALURL
#These last steps must be done quickly, as the REALURL seems to have a short-lived 
#cookie on it and I've had no success with  --keep-session-cookies etc.
