Question

我在Ubuntu 16.04虚拟机上有一个本地neo4j-community-3.5.6目录和一个数据库。

我想在启动时启动此服务，所以我在neo4j中创建了一个/etc/init.d脚本并将其符号链接到目录/etc/rcS.d

如果启动脚本如下：

./home/my_user/custom_folder/neo4j-community-3.5.6/bin/neo4j start

该服务正常启动，我可以从本地网络访问它。

但是，如果我修改neo4j社区发布的默认/etc/init.d脚本，如下所示：

#!/bin/sh

该服务无法启动，甚至尝试sudo service neo4j start。查看建议的journalctl -xe输出，我注意到此权限错误：

Jul 04 14:42:14 my-machine neo4j [3155]： /home/my_user/custom_folder/neo4j-community-3.5.6/bin/neo4j：第450行： /home/my_user/custom_folder/neo4j-community-3.5.6/logs/neo4j.log：权限被拒绝

我查看了/etc/init.d中文件的权限，它们对我来说看起来不错。由于从第一种情况开始启动服务，因此我认为这也不是文件/home/my_user/custom_folder/neo4j-community-3.5.6/bin/neo4j的问题。

什么原因导致此问题？

/etc/init.d/脚本文件生成权限被拒绝错误
