sonar安裝問題記錄

一、啓動時日誌中提示

Caused by: java.lang.RuntimeException: can not run elasticsearch as root

錯誤緣由：由於安全問題elasticsearch 不讓用root用戶直接運行

解決方法：liunx建立新用戶sonarUser,使用該用戶（sonarUser）運行sonar便可。

步驟：

　　一、建立用戶

[root@iZbp1bb2egi7w0ueys548qZ logs]# adduser sonarUser

　　二、設置密碼，輸入兩次密碼

[root@iZbp1bb2egi7w0ueys548qZ logs]# passwd sonarUser

　　三、進入到sonarqube-6.7.6目錄的上一級更改sonarqube目錄的用戶組爲sonarUser

[root@bogon local]# chown -R sonarUser:sonarUser sonarqube-6.7.6

　　四、從新啓動sonar，要使用新建的用戶啓動

 su sonarUser ./sonar.sh restart

二、啓動時提示端口占用

org.elasticsearch.bootstrap.StartupException: BindTransportException[Failed to bind to [9001]]; nested: BindException[Address already in use];
Caused by: java.net.BindException: Address already in use

　　緣由：sonarqube須要使用9000端口，elasticsearch使用的是9001端口，可是Jenkins把9001端口占用了

　　解決：修改sonar.properties文件的ES端口，或者Jenkins端口修改成8082

三、修改完上面的問題後啓動提示：沒有權限

Caused by: java.io.IOException: Cannot run program "/usr/local/jdk1.8.0_191/jre/bin/java" (in directory "/usr/local/sonarqube-6.7.6"): error=13, Permission denied

　　解決：修改目錄權限

chmod 777 /usr/local/jdk1.8.0_191/jre/bin/java

　　再次啓動，沒有報錯，訪問一下

 四、報錯：ERROR: Please provide compiled classes of your project with sonar.java.binaries property

　　緣由：最新版本的sonarQube6.5只能掃描class文件

　　解決：新版本的須要在項目根目錄下的sonar-project.properties文件新增屬性sonar.java.binaries

　　　　　　指定class編譯路徑

　　

# must be unique in a given SonarQube instance
sonar.projectKey=cynomys:0.0.1
# this is the name and version displayed in the SonarQube UI. Was mandatory prior to SonarQube 6.1.
sonar.projectName=cynomys
sonar.projectVersion=0.0.1

# Path is relative to the sonar-project.properties file. Replace "\" by "/" on Windows.
# This property is optional if sonar.modules is set.
sonar.sources=.
sonar.exclusions=**/test/**,**/target/**

sonar.java.source=1.8
sonar.java.target=1.8

# Encoding of the source code. Default is default system encoding
sonar.sourceEncoding=UTF-8
sonar.java.binaries=/root/.jenkins/workspace/e-content/e-content-controller/target/classes                                                                       

 五、運行一段時間後服務掛掉

查看sonar.log日誌

[root@bogon logs]# tail -f sonar.log

提示這個文件訪問沒有權限：java.nio.file.AccessDeniedException: /usr/local/sonarqube-7.4/temp/conf/es/elasticsearch.yml

原來是以前可能不當心用root啓動過會建立temp目錄，該目錄爲root用戶全部，當使用本身建立的sonarUser用戶啓動時就會報錯，

解決：

修改此目錄的所屬用戶組

chown -R sonarUser:sonarUser /usr/local/sonarqube-7.4/temp
