由于Elasticsearch无法作为root用户运行而导致无法运行Sonar Server

我正在尝试安装SonarQube：我已经遵​​循了以下步骤：

设置SOnarQube Tuto：此处

总结一下：

• 下载Sonar并将其移至 /opt/sonar

• 将这些coonfig步骤添加到/opt/sonar/conf/sonar.properties：

  sonar.jdbc.username = sonar sonar.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

• 实现声纳即服务：

须藤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

完成这些步骤之后：我试图从中运行Sonar：localhost:9000/sonar执行后：sudo /etc/init.d/sonar start`奇怪的是，它没有运行。

因此，当我运行sudo /etc/init.d/sonar status时，我发现它在几秒钟后便开始运行，并且在日志文件中引发了一些错误，如下所示：
