DevOps之持续集成SonarQube代码质量扫描

一、SonarQube介绍

      SonarQube是一个用于代码质量检测管理的开放平台，可以集成不同的检测工具，代码分析工具，以及持续集成工具。SonarQube 并不是简单地把不同的代码检查工具结果直接显示在 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。
　　SonarQube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 SonarQube 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SonarQube，另外Sonar的插件还可以对Java以外的其他编程语言提供支持。

二、代码质量

1.编码规范：是否遵守了编码规范，遵循了最佳实践。
2.潜在的BUG：可能在最坏情况下出现问题的代码，以及存在安全漏洞的代码。
3.文档和注释：过少（缺少必要信息）、过多（没有信息量）、过时的文档或注释。
4.重复代码：违反了Don’tRepeat Yourself原则。
5.复杂度：代码结构太复杂（如圈复杂度高），难以理解、测试和维护。
6.测试覆盖率：编写单元测试，特别是针对复杂代码的测试覆盖是否足够。
7.设计与架构：是否高内聚、低耦合，依赖最少。

三、SonarQube部署

1、部署SonarQube

官方地址
https://www.sonarqube.org/downloads/

 ①Sonar需要至少JDK 1.8及以上版本

#解压上传的jdk#
tar xf jdk-8u161-linux-x64.tar.gz -C /usr/local/
ln -s /usr/local/jdk1.8.0_161 /usr/local/jdk
ln -s /usr/local/jdk/bin/java /usr/bin/java
#配置环境变量#
vim /etc/profile
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH
source  /etc/profile

②部署SonarQube数据库(mysql5.6 或者更高版本)

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum install mysql-community-server
systemctl start mysqld.service
#初次安装mysql是root账户是没有密码的#
set password for ‘root’@‘localhost’ = password('mypasswd');
flush privileges;

执行SQL语句

CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL ON sonar.* TO 'sonar'@'localhost' IDENTIFIED BY 'sonar@pw';
GRANT ALL ON sonar.* TO 'sonar'@'%' IDENTIFIED BY 'sonar@pw';
FLUSH PRIVILEGES;

配置Sonar数据库

vim /usr/local/sonarqube/conf/sonar.properties

sonar.web.host=0.0.0.0       #监听的IP地址
sonar.web.port=9003          #监听的端口
sonar.jdbc.username=sonar    #数据库用户名
sonar.jdbc.password=sonar@pw #数据库密码
sonar.jdbc.url=jdbc:mysql://192.168.29.176:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance

Oracle数据库

手动复制驱动类到${SONAR_HOME}/extensions/jdbc-driver/oracle/目录下

参考官方文档：http://docs.sonarqube.org/display/HOME/SonarQube+Platform

③启动SonarQube

/usr/local/sonarqube/bin/linux-x86-64/sonar.sh start
tail /usr/local/sonarqube/logs/sonar.log #日志文件

Web页面登陆：http://IP:9003 默认为9000端口，默认用户名密码admin/admin

④SonarQube插件

存放插件目录/usr/local/sonarqube/extensions/plugins/

Sonar页面汉化：Chinese Pack

2、SonarQube Scanner扫描器

①官方文档

https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner
#Sonar通过Scanner（扫描器）来对代码进行质量分析#

②下载Scanner扫描器

#上传插件包：sonar-scanner-2.8.zip#
unzip sonar-scanner-2.8.zip
mv sonar-scanner-2.8 /usr/local/
ln -s /usr/local/sonar-scanner-2.8/ /usr/local/sonar-scanner

③SonarQube集成Scanner

vim /usr/local/sonar-scanner/conf/sonar-scanner.properties
sonar.host.url=http://192.168.29.175:9006    #sonar地址
sonar.sourceEncoding=UTF-8                   #字符集
sonar.jdbc.username=sonar                    #数据库账号
sonar.jdbc.password=sonar@pw                 #数据库密码
sonar.jdbc.url=jdbc:mysql://192.168.29.175:3306/sonar?useUnicode=true&characterEncoding=utf8    #数据库连接地址

④项目代码库测试

github:https://github.com/SonarSource/sonar-examples 
下载软件包：https://github.com/SonarSource/sonar-examples/archive/master.zip

⑤项目代码下配置sonar-project.properties

sonar.projectKey=
sonar.projectName=#这个名称会显示在Sonar的web页面
sonar.projectVersion=
sonar.sources=.   #源码路径
sonar.language=java
sonar.sourceEncoding=UTF-8

⑥代码质量扫描

#进入到项目下执行#
/usr/local/sonar-scanner/bin/sonar-scanner

解决：SonarQube6.7.6版本下面的sonar-java插件为 sonar-java-plugin-4.15.0.12310.jar

更换为其他版本：sonar-java-plugin-4.3.0.7717.jar
