linux - Elasticsearch cannot running as root导致无法运行Sonar Server

Question

我正在尝试安装 SonarQube:我已按照这些步骤操作:

Setting up SOnarQube Tuto : here

总结一下:

• 下载 Sonar 并将其移动到 /opt/sonar

• 将这些配置步骤添加到 /opt/sonar/conf/sonar.properties :

  sonar.jdbc.username=sonarsonar.jdbc.password=sonar

sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance

和

sonar.web.host=127.0.0.1
sonar.web.context=/sonar
sonar.web.port=9000

• 将sonar作为服务实现:

sudo cp/opt/sonar/bin/linux-x86-64/sonar.sh/etc/init.d/sonar

sudo gedit /etc/init.d/sonar

插入两行:

SONAR_HOME=/opt/sonar
PLATFORM=linux-x86-64
Modify the following lines:

WRAPPER_CMD="${SONAR_HOME}/bin/${PLATFORM}/wrapper"
WRAPPER_CONF="${SONAR_HOME}/conf/wrapper.conf"

...

PIDDIR="/var/run"
Register as a Linux service:

sudo update-rc.d -f sonar remove
sudo chmod 755 /etc/init.d/sonar
sudo update-rc.d sonar defaults

在这些步骤之后:我尝试从 localhost:9000/sonar 运行 Sonar 并在执行之后:sudo/etc/init.d/sonar start`奇怪的是，它没有运行。

所以当我运行 `sudo/etc/init.d/sonar status 时，我发现它会在几秒钟后执行步骤，并在日志文件中抛出一些错误，如下所示:

有什么建议吗？？

SonarSource 升级了用作最新 SonarQube LTS 版本一部分的 Elasticsearch 工具。因此，SonarQube 不能以 root 身份运行。参见 this博客和 SonarQube 6.6升级说明和this SO问题。
