systemctl限制- solr投诉

Question

我正在构建一个solr服务器(在Ubuntu18.04上，使用回购solr通用和solr-jetty)。在启动时，solr报告说nfile和nproc (1024,6721 resp)设置得太低了。我运行了systemctl edit solr并创建了一个覆盖如下：

[Service]
LimitNOFILE=65000
LimitNPROC=65000

然后我重新启动了服务- solr仍然报告了同样的问题。

我增加了/etc/security/limits.d.d/solr，其中包括：

solr hard nofile 65535
solr soft nofile 65535
solr hard nproc 65535
solr soft nproc 65535

在重新启动服务之后，它仍然报告同样的问题：

我在这里做错什么了？

修改/etc/systemd/system.conf后进行更新，以包含.

DefaultLimitNOFILE=65000
DefaultLimitNPROC=65000

Solr不再抱怨文件限制，但仍然抱怨进程限制。WTF便餐？

修改user.conf以匹配没有帮助。

更新2--好吧，这只会越来越好。nfile警告的消失发生在主机重新启动之后。当我随后运行systemctl restart solr时，我得到了以下内容：

Mar 30 15:39:21 dev-a01-si-solr.bip solr[2503]: *** [WARN] *** Your open file limit is currently 1024.
Mar 30 15:39:21 dev-a01-si-solr.bip solr[2503]:  It should be set to 65000 to avoid operational disruption.

FFS！

我把Centos 5光盘放哪儿了？

更新3

事实证明，这不再是包装的solr。在我看来，有人在让最初的构建开始工作时遇到了问题，并在互联网上找到了一个关于如何从tarball安装的教程。所以我现在有了一个系统，它有半个tarball/半个repo solr，我们不能修补/升级。

Answer 1

在Ubuntu18.04上，solr实际上是由从systemd调用的initV脚本启动的。

我已经消除了警告

1)删除/etc/security/limits.d s.d/solr，并在/etc/security/limits.d s.conf中添加以下内容：

*                hard   nofile 2048
*                hard   nproc  2048

root             hard   nofile unlimited
root             soft   nofile unlimited
root             hard   nproc  unlimited
root             soft   nproc  unlimited

solr hard nofile 65535
solr soft nofile 65535
solr hard nproc 65535
solr soft nproc 65535

2)将其添加到/etc/init.d/solr的顶部。

ulimit -n 65000
ulimit -u 65000

(尽管-u行似乎没有做任何事情)

3)运行systemctl daemon-reload

( 4)重新启动

当我运行systemctl reload solr时，警告就会远离。

但我现在的配置机器人遍布各地，我需要修剪掉其中的一些。
