Linux Can'；t运行由Elasticsearch导致的Sonar服务器无法以root用户身份运行

我正在尝试安装SonarQube：我遵循了以下步骤：

总结一下：

• 下载声纳并将其移动到

  /opt/Sonar

• 将这些配置步骤添加到

  /opt/sonar/conf/sonar.properties

  ：
  sonar.jdbc.username=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

• 将声纳作为一项服务实施：

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

sudo gedit /etc/init.d/sonar

插入两行新行：

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：我尝试从以下位置运行Sonar：

localhost:9000/Sonar

，执行之后：

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已经升级了作为最新SonarQube LTS版本一部分使用的Elasticsearch工具。因此，SonarQube不能作为根运行。请参阅博客以及升级说明和问题。

更改sonar文件的根访问权限。尝试在正常用户访问中运行

chown <another user>:<user group> sonar.sh

chown:sonar.sh

我也面临同样的问题，在得到解决方案之前花了很长时间

错误与

2017.12.09 18:05:14 ERROR es[][o.e.b.Bootstrap] Exception
java.lang.RuntimeException: can not run elasticsearch as root
    at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:106) ~[elasticsearch-5.6.3.jar:5.6.3]
    at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:195) ~[elasticsearch-5.6.3.jar:5.6.3]

解决方案 使用adduser命令创建一个“sonar”用户//我使用的是linux系统 chown-R sonar sonar安装文件夹/ 在开始脚本中编辑sonar.sh文件sonar install folder/bin/linux-x86-6，并将#RUN_AS_USER改为RUN_AS_USER=sonar

然后使用下面的命令

./sonar.sh stop

优雅地停下来。。。 库贝没有跑

./sonar.sh start

正在启动声纳qube。。。 从库贝开始

./sonar.sh status

SonarQube正在运行（22100）

所以，基本上弹性搜索不需要由root用户运行。默认情况下，启动脚本会对RUN_AS_用户进行注释，该脚本会选择我当前的root用户，然后出现一些linux权限规则，原因是elasticsearch进程没有启动，导致sonar进程也停止运行

从sonar.log上可以明显看出

[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

我不知道Sonar是如何启动elasticsearch的，但可以肯定的是，elasticsearch不能以root用户身份运行。除非设置了setuid，否则更改文件的所有权不会影响其在运行时的权限。有什么原因突然不再接受此答案吗？
