一、Sonar 介绍
Sonar 是一个用于代码质量管理的开放平台。通过插件机制，Sonar可以集成不同的测试工具，代码分析工具，以及持续集成工具。与持续集成工具（例如 Hudson/Jenkins 等）不同，Sonar 并不是简单地把不同的代码检查工具结果（例如 FindBugs，PMD 等）直接显示在 Web 页面上，而是通过不同的插件对这些结果进行再加工处理，通过量化的方式度量代码质量的变化，从而可以方便地对不同规模和种类的工程进行代码质量管理。
在对其他工具的支持方面，Sonar 不仅提供了对 IDE 的支持，可以在 Eclipse和 IntelliJ IDEA 这些工具里联机查看结果；同时 Sonar 还对大量的持续集成工具提供了接口支持，可以很方便地在持续集成中使用 Sonar。
此外，Sonar 的插件还可以对 Java 以外的其他编程语言提供支持，对国际化以及报告文档化也有良好的支持。
二、Sonar 安装
Sonar 的相关下载和文档可以在下面的链接中找到：http://www.sonarqube.org/downloads 。 需要注意最新版的 Sonar 需要至少JDK 1.8及以上版本。
之前我们已经可以成功的使用 git 进行拉取，Sonar 的功能就是来检查代码是否有BUG。除了检查代码是否有 bug 还有其他的功能，比如说：你的代码注释率是多少，代码有一些建议，编写语法的建议。所以我们叫质量管理
Sonar 还可以给代码打分，并且引用了技术宅的功能（告诉你有很多地方没改）
1、安装 jdk
JDK 可以去 Oracle 官网去下载，也可以使用 yum 仓库的 JDK。
rpm -ivh jdk-8u45-linux-x64.rpm2、下载安装包
我这里下载的是长期维护的一个版本6.7.5。
wget https://sonarsource.bintray.com/Distribution/sonarqube/sonarqube-6.7.5.zip3、解压
unzip sonarqube-6.7.5.zip
mv sonarqube-6.7.5 /usr/local/sonarqube三、准备数据库
因为 sonar 会用到数据库，所以我们要事先准备好数据库，它支持多种数据库，我们这里选择的是 MySQL/Mariadb，注意 MySQL 的版本最低要5.6，因为我这里有现有的数据库，所以安装过程省略。
mysql> CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;
mysql> GRANT ALL ON sonar.* TO 'sonar'@'localhost' IDENTIFIED BY 'sonar@pw';
mysql> GRANT ALL ON sonar.* TO 'sonar'@'%' IDENTIFIED BY 'sonar@pw';
mysql> FLUSH PRIVILEGES;四、配置 Sonar
1、配置数据库连接
编辑/usr/local/sonarqube/conf/sonar.properties，修改内容如下：
# 数据库连接
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar@pw
sonar.jdbc.url=jdbc:mysql://10.0.1.13:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance&useSSL=false
# Web 端口
sonar.web.host=0.0.0.0
sonar.web.port=90002、创建用户 sonar
因为程序不允许我们使用 root 执行，所以我们需要注册一个普通用户
useradd sonar
chown sonar.sonar /usr/local/sonarqube -R3、启动 sonar
[sonar@monitor ~]$ /usr/local/sonarqube/bin/linux-x86-64/sonar.sh start
Starting SonarQube...
Started SonarQube.4、检查是否启动成功
[root@monitor ~]# netstat -tlnp
Active Internet connections (only servers)

tcp 0 0 :::80 :::* LISTEN 4841/httpd 五、登录 sonar
Web登录：IP:9000
sonar跟jenkins类似，也是以插件为主。
sonar安装插件有2种方式：第一种将插件下载完存放在sonar的插件目录，第二种使用web界面来使用安装存放插件路径[/usr/local/sonarqube/extensions/plugins/]。
1、安装中文插件
登陆：用户名：admin 密码：admin。
重启才会生效。
生效后界面如下。
和 jenkins 一样，需要什么插件直接去应用市场下载即可。
2、安装 sonar 扫描器
Sonar通过SonarQube Scanner（扫描器）来对代码进行分析。
wget https://sonarsource.bintray.com/Distribution/sonar-scanner-cli/sonar-scanner-2.8.zip
unzip sonar-scanner-2.8.zip
mv sonar-scanner-2.8 /usr/local/sonar-scanner3、扫描器和 sonar 关联起来
编辑文件/usr/local/sonar-scanner/conf/sonar-scanner.properties，修改为如下内容：
sonar.host.url=http://localhost:9000
sonar.sourceEncoding=UTF-8
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar@pw
sonar.jdbc.url=jdbc:mysql:/10.0.1.13:3306/sonar?useUnicode=true&characterEncoding=utf8六、代码扫描
1、下载代码
sonar 插件提供了一个测试的代码库。
github：https://github.com/SonarSource/sonar-scanning-examples
下载地址：https://codeload.github.com/SonarSource/sonar-scanning-examples/zip/master
wget https://codeload.github.com/SonarSource/sonar-scanning-examples/zip/master
unzip master
cd sonar-scanning-examples-master/sonarqube-scanner2、sonar-project.properties
我们会看到项目下面有一个文件 sonar-project.properties，如果想要代码被扫描，就需要在代码路径下放一个配置文件。
[root@monitor sonarqube-scanner]# cat sonar-project.properties
sonar.projectKey=org.sonarqube:sonarqube-scanner #Key
sonar.projectName=Example of SonarQube Scanner Usage #这里的名称会显示在web上面
sonar.projectVersion=1.0 #版本，也会显示在web上面
sonar.sources=src,copybooks 软件包存放路径
sonar.sourceEncoding=UTF-8 #字体编码
## Cobol Specific Properties
# comma-separated paths to directories with copybooks
sonar.cobol.copy.directories=copybooks
# comma-separated list of suffixes
sonar.cobol.file.suffixes=cbl,cpy
sonar.cobol.copy.suffixes=cpy
## Flex Specific Properties
# retrieve code coverage data from the Cobertura report
sonar.flex.cobertura.reportPath=coverage-report/coverage-cobertua-flex.xml
# PL/I Specific Properties
sonar.pli.marginLeft=2
sonar.pli.marginRight=03、扫描
需要在项目文件里面进行执行，程序会在当面目录下扫描sonar-project.properties文件，根据配置文件进行扫描工作。扫描之后我们在web界面上就可以看到代码的扫描结果。
