在openshift中安装neo4j

虽然我在/neo4j/versions/2.1/neo4j-2.1/bin中运行sh neo4j console。我收到以下错误：在openshift中安装neo4j

似乎您已达到最大文件限制。这篇文章谈论它有关的Neo4j：

Neo4j WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual

具体来说，你会上的数字，/etc/security/limits.conf。您可能需要重新启动。

这似乎是可能的OpenShift：

好像你把一个shell变量Caused by: java.lang.NumberFormatException: For input string: ""${OPENSHIFT_NEO4J_DB_PORT}"" 中的Neo4j的neo4j-server.properties这是不支持的。

尝试修改你的配置脚本，而更换口内嵌在配置文件中，就像这样：

sed -i -e "s|org.neo4j.server.webserver.port=.*|org.neo4j.server.webserver.port=${OPENSHIFT_NEO4J_DB_PORT}|g" $NEO4J_HOME/conf/neo4j-server.properties
