操作系統：centos 7 (x86)
一、問題描述：使用root啟動時，一直反饋 SonarQube is not running
問題原因：不能夠使用root用戶進行啟動
解決方案：①創建一個其他用戶（如sonar) adduser sonar 設置密碼 passwd sonar
②更改sonarqube的安裝目錄的用戶組 chown -R sonar:sonar sonarqube-XXX
③切換用戶啟動 su sonar xxxx/sonar.sh start
二、啟動時可能會遇到一個現象， 服務一會掛掉或者啟動不起來，使用sonar.sh console 命令查看后，輸出日志如下：

問題原因： 用root啟動過會創建temp目錄，該目錄為root用戶所有，使用自己創建的sonar用戶啟動時就會報錯
解決方案：使用root用戶修改該文件夾的用戶組（temp)，讓它屬於sonarqube的啟動用戶（自己創建的那個），再次啟動就ok了
chown -Rf sonar:sonar /opt/sonarqube-7.6/temp
