neo4j 和最大打开文件 [英] neo4j and max open files

问题描述

我在 ubuntu 上使用 neo4j 1.8M06.当我启动它时，我收到此警告:

I'm using neo4j 1.8M06 on ubuntu. When I start it, I get this warning:

WARNING: Max 1024 open files allowed, minimum of 40 000 recommended.

是什么意思?如果需要，我该如何调整这个设置?

what does it mean? If it is required, how can I adjust this setting?

我已经在这个问题上看到了这个主题，但是还是没看懂.

I've seen this thread on the issue but still could not understand it.

推荐答案

这意味着您只能打开1024"(默认)文件进行写入.但是NEO4J推荐这个值是40K.这可以通过如下所述的修复来实现.

It means that you can open only '1024'(default) files for writing. But NEO4J recommends this value to be 40K. This can be achieved with the fix as described below.

编辑 /etc/security/limits.conf 并添加以下两行:

Edit /etc/security/limits.conf and add these two lines:

root   soft    nofile  40000
root   hard    nofile  40000

neo4j 在这里推荐使用neo4j"代替root".那行不通.

The neo4j recommends "neo4j" in place of "root" here. That won't work.

您还需要编辑 /etc/pam.d/common-session* 并在末尾添加以下行:

You also need to edit /etc/pam.d/common-session* and add the following line to the end:

session required pam_limits.so

是的，最后你必须重新启动 NEO4J.

And yes, finally you've to restart NEO4J.

sudo service neo4j-service restart
