sonar安装问题记录

1、启动时日志中提示

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

错误原因：因为安全问题elasticsearch 不让用root用户直接运行

解决方法：liunx创建新用户sonarUser,使用该用户（sonarUser）运行sonar即可。

步骤：

　　1、创建用户

[root@iZbp1bb2egi7w0ueys548qZ logs]# adduser sonarUser

　　2、设置密码，输入两次密码

[root@iZbp1bb2egi7w0ueys548qZ logs]# passwd sonarUser

　　3、进入到sonarqube-6.7.6目录的上一级更改sonarqube目录的用户组为sonarUser

[root@bogon local]# chown -R sonarUser:sonarUser sonarqube-6.7.

　　4、重新启动sonar，要使用新建的用户启动

 su sonarUser ./sonar.sh restart

2、启动时提示端口占用

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

　　原因：sonarqube需要使用9000端口，elasticsearch使用的是9001端口，但是Jenkins把9001端口占用了

　　解决：修改sonar.properties文件的ES端口，或者Jenkins端口修改为8082

3、修改完上面的问题后启动提示：没有权限

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=, Permission denied

　　解决：修改目录权限

chmod  /usr/local/jdk1..0_191/jre/bin/java

　　再次启动，没有报错，访问一下

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

　　原因：最新版本的sonarQube6.5只能扫描class文件

　　解决：新版本的需要在项目根目录下的sonar-project.properties文件新增属性sonar.java.binaries

　　　　　　指定class编译路径

　　

# must be unique in a given SonarQube instance
sonar.projectKey=cynomys:0.0.
# 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.

# 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                                                                       

5、运行一段时间后服务挂掉

查看sonar.log日志

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

2019.05. :: INFO  app[][o.s.a.AppFileSystem] Cleaning or creating temp directory /usr/local/sonarqube-7.4/temp

WrapperSimpleApp: Encountered an error running main: java.nio.file.AccessDeniedException: /usr/local/sonarqube-7.4/temp/conf/es/elasticsearch.yml
java.nio.file.AccessDeniedException: /usr/local/sonarqube-7.4/temp/conf/es/elasticsearch.yml

提示这个文件访问没有权限：java.nio.file.AccessDeniedException: /usr/local/sonarqube-7.4/temp/conf/es/elasticsearch.yml

原来是之前可能不小心用root启动过会创建temp目录，该目录为root用户所有，当使用自己创建的sonarUser用户启动时就会报错，

解决：

修改此目录的所属用户组

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