在 Neo4j 3.1 中手动合并 neo4j-wrapper.conf 到 neo4j.conf

Neo4j 3.1 将 Neo4j 3.0 中进行的配置更改更进一步，并附带一个配置文件：conf/neo4j.conf。这是合并conf/neo4j.conf和conf/neo4j-wrapper.conf内容的结果。升级不会自动合并这些文件，并且conf/neo4j-wrapper.conf已弃用，但在 3.x 结束前仍受支持。因此，合并这两个文件在此时是可选的，但在为将来版本做准备时是一个好的步骤。

可以简单地复制conf/neo4j-wrapper.conf的全部内容，并将其粘贴到conf/neo4j.conf的末尾。或者，使用下面的示例脚本。只需复制脚本，将其粘贴到$NEO4J_HOME/bin中具有执行权限的新文件中，然后运行它。

#!/usr/bin/env bash
# This script will merge an existing neo4j.conf and neo4j-wrapper.conf
# This script is designed to be run from the bin/ directory of Neo4j, and expects both neo4j.conf
# and neo4j-wrapper.conf to be located in the conf/ directory.
# This is a sample script that is not part of the Neo4j project.
# Please be sure to read, understand and adapt this script as appropriate for your environment
