Question

获取错误“ Neo4j无法启动，因为数据库文件需要在配置中进行升级和升级。请在配置文件中将”dbms.allow_upgrade“设置为”true“ / strong>“当我尝试通过其Java驱动程序连接neo4j时。

尽管我已在dbms.allow_upgrade文件中将属性true设置为neo4j.conf，但没有任何更改。

Answer 1

这对我有用，升级到3.3.1 neo4j Docker镜像！我试过以下但是这对于3.0：

都不起作用

 docker run \
  --publish=7474:7474 --publish=7687:7687 \
  --volume=$HOME/neo4j/data:/data \
  --volume=$HOME/neo4j/logs:/logs \
  --env=NEO4J_dbms_allow_upgrade=true \
  --env=NEO4J_dbms_allow_format_migration=true \
  neo4j:3.0

Answer 2

在我的情况下，问题是配置文件不是我想的那个。

根据this documentation，它应该在<neo4j-home>/conf/neo4j.conf

之下

然而，运行neo4j stop然后neo4j start打印出几条关键路径。

Directories in use: home: /var/lib/neo4j config: /etc/neo4j logs: /var/log/neo4j plugins: /var/lib/neo4j/plugins import: /var/lib/neo4j/import data: /var/lib/neo4j/data certificates: /var/lib/neo4j/certificates run: /var/run/neo4j

因此，编辑/etc/neo4j下的配置工作。

无法启动Neo4j，因为数据库文件需要升级，并且配置中禁用了升级
