我也遇到过这个问题，在 Centos 7 上以 root 身份运行 SonarQube，而不是在 docker 中。之前的评论中提到，问题来自SonarQube升级ElasticSearch，新版本不再允许自身以root身份运行。

在我的环境中，修复非常简单:我已经创建了一个用户(“sonar”)和组(“sonar”)来“拥有”sonarqube 文件。由于我的 SonarQube 进程一直以 root 身份运行，因此它保留了 root 拥有的日志和临时文件。
1.我停止了服务。
2.重新分配所有所有权(“chown -R sonar:sonar/opt/sonarqube-6.6”)
3. 更改#RUN_AS_USER=在/opt/sonarqube-6.6/bin/linux-x86-64/sonar.sh第 48 行到 RUN_AS_USER=sonar并且 sonarqube 服务及其 elasticsearch 服务都重新启动，没有进一步的问题。我不得不去 http://<sonarhost:port>/setup升级数据库，一切正常。
