2臺阿里服務器，系統版本
A：Linux version 3.10.0-693.2.2.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Tue Sep 12 22:26:13 UTC 201

B：Linux version 3.10.0-957.10.1.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ) #1 SMP Mon Mar 18 15:06:45 UTC

現狀是A服務器啓動不了sonar,B服務器可以啓動。都是使用sonar用戶上去解壓啓動。其中A就一直要輸入用戶密碼，很是不解。而且需要輸入的還是root用戶的密碼。啓動結果當然是ES不支持root用戶啓動了、只能是修改sonar.sh文件 指定用戶了RUN_AS_USER=sonar 這樣才能啓動
A服務器通過bash -x ./sonar.sh start啓動查看跟B服務覈對有一下差異：
能力水平不行，至今未知曉是啥原因，有知曉的童鞋，請回復。在此敬禮謝過

sonar啓動後。入手maven代碼檢查，參照官網https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner+for+Maven 操作了一番。mvn org.sonarsource.scanner.maven:sonar-maven-plugin:3.6.0.1398:sonar -Dsonar.host.url=http://127.0.0.1:9000
其中有出現以下錯誤： maven顯示的upload失敗，上傳檢測報告失敗。通過在sonar目錄下logs文件夾 web.log日誌，一目瞭然發現是mysql的max_allowed_packet太小導致。只需要將這個配置重新設置重啓下mysql，就能順利上傳
