一、环境准备
安装环境为centos6.5，需要准备的软件有sonarqube、sonar-scanner、jdk1.8.0、mysql。sonarqube也支持oracle(11g/12c)、postgresql(8.x/9.x)、SqlServer(2008/2012/2014 and SQL Azure)、mysql(5.6以上)多种数据库。此案例选择mysql。
1.1 SonarQube
下载地址：https://www.sonarqube.org/downloads/ 。目前官网最新版本为7.5，BI目前使用的版本为7.5。
1.2 JDK
官网信息，需要用到jdk1.8,如果你的环境已经配置了JAVA_HOME是jdk1.7，没关系我们可以手动指定sonar的运行jdk为1.8（后面配置的时候说明）。
1.3 MySQL
1.检测系统是否自带安装mysql
yum list installed | grep mysql
2.如果发现有系统自带mysql，先卸载
yum -y remove mysql-libs.x86_64
3.下载mysql的yum源
wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
4.接着执行一下命令添加yarn源,在/etc/yum.repos.d/这个目录下多出mysql-community-source.repo和mysql-community.repo
rpm -ivh mysql-community-release-el6-5.noarch.rpm
5.查看一下是否已经有mysql可安装文件
yum repolist all | grep mysql
6.安装mysql服务器命令（一路yes）：
yum install mysql-community-server
7.安装成功后
service mysqld start
8.由于mysql刚刚安装完的时候，mysql的root用户的密码默认是空的，所以我们需要及时用mysql的root用户登录（第一次回车键，不用输入密码），并修改密码
mysql -u root;
use mysql;
update user set password=PASSWORD("这里输入root用户密码") where User='root';
flush privileges;
9.查看mysql是否自启动,并且设置开启自启动命令
chkconfig --list | grep mysqld
chkconfig mysqld on
10.mysql 添加sonar用户
CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER 'sonar' IDENTIFIED BY 'sonar';
GRANT ALL ON sonar.* TO 'sonar'@'%' IDENTIFIED BY 'sonar';
GRANT ALL ON sonar.* TO 'sonar'@'localhost' IDENTIFIED BY 'sonar';
FLUSH PRIVILEGES;
二、SonarQube安装
1.新建一个用户
groupadd sonar
useradd sonar -g sonar -p sonar
2.新建sonarqube目录
mkdir -p /usr/local/sonarqube
chown sonar:sonar /usr/local/sonarqube
3.使用sonar解压软件包到目录/usr/local/sonarqube
su - sonar
unzip -d /usr/local/sonarqube sonarqube-7.5.zip
4.配置JDK
vi /usr/local/sonarqube/sonarqube-7.5/conf/wrapper.conf
wrapper.java.command=/usr/java/default
wrapper.java.command=java
5.配置数据库账号
vi /usr/local/sonarqube/sonarqube-7.5/conf/sonar.properties
sonar.jdbc.username=root
sonar.jdbc.password=root
sonar.jdbc.url=jdbc:mysql://172.17.213.205:3306/sonar?useUnicode=true&characterEncoding=utf8&useConfigs=maxPerformance&rewriteBatchedStatements=true
sonar.web.host=172.17.213.205
sonar.web.context=/sonarqube
sonar.web.port=9000
sonar.login=admin
sonar.password=admin
6.启动SonarQube
/usr/local/sonarqube/sonarqube-7.5/bin/linux-x86-64/sonar.sh start
7.查看启动日志
tail -200f ./logs/sonar.log

8.汉化SonarQube
使用admin/admin账号登录，选择Marketplace，找到Chinese Pack，点击install安装语言包，然后重启server，重新加载页面就完成汉化。

三、Maven配置SonarQube
1.安装Maven
mkdir -p /usr/local/maven3
cd /root/software
wget http://mirrors.hust.edu.cn/apache/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz
tar zxf apache-maven-3.5.4-bin.tar.gz
mv apache-maven-3.5.4 /usr/local/maven3
2.配置环境变量。
vi /etc/profile
export M2_HOME=/usr/local/maven3/apache-maven-3.5.4
export PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
3.保存退出后运行下面的命令使配置生效，或者重启服务器生效。
source /etc/profile
4.验证版本
mvn -v
5.安装maven,配置maven环境变量(过程略)。
要实行对maven项目的管理，还需要配置maven的setting.xml文件。
配置如下：
<profile>
<id>sonar</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<!-- database-->
<sonar.jdbc.url>jdbc:mysql://172.17.213.205:3306/sonar</sonar.jdbc.url>
<sonar.jdbc.driver>com.mysql.jdbc.Driver</sonar.jdbc.driver>
<sonar.jdbc.username>sonar</sonar.jdbc.username>
<sonar.jdbc.password>sonar</sonar.jdbc.password>
<!-- Optional URL to server. Default value is http://localhost:9000 -->
<sonar.host.url>http://172.17.213.205:9000</sonar.host.url>
<sonar.login>admin</sonar.login>
<sonar.password>admin</sonar.password>
</properties>
</profile>
