由于内存问题，无法启动sonarqube

Question

我正在按照本教程在我的CentOS 7中设置SonarQube：https://thegeeksalive.com/how-to-install-sonarqube-on-centos/

最后我启动了我的Sonar，但它不能启动，因为这里的内存问题。

希望大家能帮我找到解决方案。谢谢!

Answer 1

检查SonarQube主目录中的logs/es.log中的内容。在Linux上启动SonarQube的许多问题都会显示消息，比如max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

如果您看到这一点，那么您应该在启动SonarQube之前运行以下命令

sysctl -w vm.max_map_count=262144
sysctl -w fs.file-max=65535

Answer 2

此错误最有可能是由于项目太大，SonarQube无法使用默认内存设置进行扫描。

尝试以下解决方法：

1. 增加系统上的Java堆大小：

export _JAVA_OPTIONS="-Xmx1g"

1. 更新$SONARQUBE_HOME/conf/sonar.properties中的javaOpts属性以授予更多内存。
