无法在Ubuntu中启动Sonarqube

当我试图启动sonarqube时，它会给我以下错误

Elasticsearch未启动，请参阅日志：

2019.08.20 20:38:37错误es[][o.e.b.Bootstrap]节点验证异常 [1] 引导检查失败 [1] ：elasticsearch进程的最大文件描述符[4096]太低，至少增加到[65535]

下面是他们在书中所说的：

Elasticsearch使用大量文件描述符或文件句柄。跑步 文件外描述符可能是灾难性的，很可能导致 数据丢失。确保增加打开的数量限制 运行Elasticsearch至65536或 更高

因此，您需要增加限额：

对于.zip和.tar.gz包，在之前将ulimit-n 65535设置为root 正在启动Elasticsearch，或在中将nofile设置为65535 /etc/security/limits.conf

---

解决方案是使用sonar.service文件，该文件应保存在/etc/systemd/system.sonar.service中

您必须定义服务上的文件限制

您需要设置fs.file-max以增加max文件描述符

sysctl-w fs.file max=65535

您可能还需要设置vm.max-map-count

sysctl-w vm.max\u map\u count=262144

---

你能分享你的es.log的内容吗？@mc1arke es.log文件被添加。我这样做了，但问题仍然存在。你在启动Elasticsearch的同一个shell中执行了ulimit？我在/etc/security/limits.cong中设置了nofile。可以吗？老实说，我不知道它是如何与limits.conf一起工作的。他们给出了两种解决方案，两种都试试！是的。但一切都没有改变。ulimit-n命令的输出为65536。但这并不是全部答案。您还必须更改服务文件。
