如何使用MongoDB支持的Apache Oak运行Sling
目标：使用Apache Oak作为JCR提供程序运行Apache Sling，并将MongoDB作为后备数据存储区。
步骤到目前为止： 安装了MongoDB（3.0.2）并验证并运行 克隆：https://github.com/apache/sling.git 使用maven构建：mvn clean install 使用以下命令在本地运行：
java -jar target/org.apache.sling.launchpad-*.jar -c test -f -
这很好用，但现在我想转而使用Apache Oak和MongoDB。 Launchpad App文档似乎描述了执行以下操作的可能性：
java -jar target/org.apache.sling.launchpad-*.jar -Dsling.run.modes=oak,oak_mongo
但是，当我这样做时，我没有看到与正在运行的Mongo实例建立任何连接。
已审核文档到目前为止：
输入启动板/构建器目录并首次启动Sling
$ cd launchpad/builder
$ java -jar target/org.apache.sling.launchpad-*.jar -c test -f -
更新：2015年5月19日
正如罗伯特建议的那样，我已经启动了一个2.6.8的Mongo实例，并尝试启动Sling以查看是否存在任何连接:( Mongo日志中出现的连接来自与RoboMongo的连接而不是据我所知，吊索。浏览http://localhost:8080/.explorer.html#，不会触发Mongo日志中的任何输出。

Per Roberts的建议：
你的日志中的runmodes不正确，你应该使用-Dsling.run.modes = oak，oak_mongo -
改变了runmodes和reran Sling。

根据罗伯特的最新建议，似乎成功连接到mongodb。如上所述，但有一些例外情况被抛出。
1 个答案:
答案 0 :(得分：0)
据我所知，我们目前在Sling中使用的Oak 1.2在MongoDB 2.6.x上进行了测试。您可以尝试使用最新的2.6.x版MongoDB而不是3.0.x吗？
如果可以，并且您想使用最新版本的MongoDB，则应使用最新的驱动程序，例如：将补丁应用于Sling git repo，如
diff --git a/launchpad/builder/src/main/provisioning/oak.txt b/launchpad/builder/src/main/provisioning/oak.txt
