OpenShift中DIY盒带的JDK 8支持
我知道，但我能在实验DIY盒带上安装Java8吗？java-1.7.0是在/usr/lib上提供的最新版本。如果需要特定的JDK版本，可以下载它并设置环境变量：OpenShift中DIY盒带的JDK 8支持,openshift,java-8,Openshift,Java 8,我知道，但我能在实验DIY盒带上安装Java8吗？java-1.7.0是在/usr/lib上提供的最新版本。如果需要特定的JDK版本，可以下载它并设置环境变量： cd $OPENSHIFT_DATA_DIR wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8

嗨，我想更新上面的答案，因为我同样需要为我的Vert.x应用程序更新JDK。由于它完全是用Java8编写的（Vert.x代码看起来更好），我开始用Openshift做一些实验，直到遇到juan报告的问题 但是，我必须修复一些东西并更新到JDK1.8u20：
// connect with SSH to your application, then
cd $OPENSHIFT_DATA_DIR
wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u20-b26/jdk-8u20-linux-x64.tar.gz
tar -zxf jdk-8u20-linux-x64.tar.gz
export PATH=$OPENSHIFT_DATA_DIR/jdk1.8.0_20/bin:$PATH
export JAVA_HOME=$OPENSHIFT_DATA_DIR/jdk1.8.0_20/
// then depending on your cartridge you need to exec the following command
echo $JAVA_HOME > $OPENSHIFT_{cartridge}_DIR/env/JAVA_HOME
// in my case was
// echo $JAVA_HOME > $OPENSHIFT_VERTX_DIR/env/JAVA_HOME
// for Wildfly I presume it is
// echo $JAVA_HOME > $OPENSHIFT_WILDFLY_DIR/env/JAVA_HOME
如果您将Maven与DIY盒带一起使用，则此操作不起作用 如果查看框中“/usr/bin/mvn”中的mvn命令，您将看到执行时mvn重置$JAVA\u HOME

希望这能帮助其他像我一样花了很多时间在这方面的人：）默认的wildfly 8（8.2.1）盒带现在支持JDK8开箱即用。Java 8现在默认情况下可以使用DIY。您只需在/.openshift/action\u hooks/start.sh中设置下面给出的路径即可
export JAVA_HOME=/etc/alternatives/java_sdk_1.8.0
export PATH=$JAVA_HOME/bin:$PATH
我预计出口也将进入启动阶段。如果我错了，请纠正我！我觉得没必要，这些出口对我来说已经足够了。这是新的DIY吗？甚至在重新启动盒式磁带之后？我还需要在.OPENSHIFT/action\u hooks/pre\u start\u WILDFLY中添加“export-OPENSHIFT\u WILDFLY\u JDK8=$OPENSHIFT\u DATA\u DIR/jdk1.8.0\u 31/”到.OPENSHIFT/action\u hooks/pre\u start\u wildflyse sathish的答案中-DIY包现在包括JDK 1.8，只是默认情况下不在路径上。我有三个位置放置
action\u hooks/app root/runtime/repo/.openshift/action\u hooks
