1.安装java（最新版本sonar需要至少JDK 1.8及以上版本）
[root@Centos7-1 ~]# yum -y install java
[root@Centos7-1 ~]# java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-b10)
OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode)
2.安装mysql数据库（这里使用mysql 5.7）
[https://dev.mysql.com/downloads/repo/yum/](https://dev.mysql.com/downloads/repo/yum/)
下载yum源，然后安装
[root@Centos7-1 ~]# rpm -ivh mysql80-community-release-el7-1.noarch.rpm
编辑yum库，开启5.7的yum源，关闭8.0
[root@Centos7-1 ~]# vim /etc/yum.repos.d/mysql-community.repo
# Enable to use MySQL 5.7
[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
[mysql80-community]
name=MySQL 8.0 Community Server
baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/7/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
[root@Centos7-1 ~]# yum -y install mysql-community-client mysql-community-server
[root@Centos7-1 ~]# mysql --version
mysql Ver 14.14 Distrib 5.7.22, for Linux (x86_64) using EditLine wrapper
3.修改mysql配置，并启动
[root@Centos7-1 ~]# vim /etc/my.cnf
[mysqld]
validate-password=OFF #关闭复杂密码验证
max_allowed_packet=1024M #限制Server接受的数据包大小
#限制过小，会引起扫描结果无法上传到服务器
[root@Centos7-1 ~]# systemctl restart mysqld; systemctl enable mysqld
初始化数据库
初次安装的mysql密码在/var/log/mysql.log里面
[root@Centos7-1 ~]# cat /var/log/mysqld.log | grep password
2018-06-14T06:15:31.925974Z 1 [Note] A temporary password is generated for root@localhost: c;G5_ldQkI1I
[root@Centos7-1 ~]# mysql_secure_installation
4.创建sonar数据库及用户
[root@Centos7-1 ~]# mysql -u root -p123
mysql> CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;
mysql> GRANT ALL ON sonar.* TO 'sonar'@'%' IDENTIFIED BY 'sonar';
mysql> FLUSH PRIVILEGES;
5.下载sonarqube（这里使用的sonarqube 7.1版本）
https://www.sonarqube.org/
解压压缩包到/usr/local/sonarqube-7.1
[root@Centos7-1 ~]# unzip sonarqube-7.1.zip -d /usr/local/sonarqube
6.修改sonarqube配置文件
[root@Centos7-1 ~]# vim /usr/local/sonarqube-7.1/conf/sonar.properties
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar #去掉注释添加数据库账号密码
sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance&useSSL=false #去掉注释
sonar.web.host=0.0.0.0 #去掉注释
sonar.web.port=9000 #去掉注释
：wq！
7.启动sonarqube
创建一个新用户（由于elasticsearch默认不能以root身份启动）
[root@Centos7-1 ~]# useradd sonar
[root@Centos7-1 ~]# passwd sonar
Changing password for user sonar.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@Centos7-1 ~]# chown -R sonar.sonar /usr/local/sonarqube-7.1/
[root@Centos7-1 ~]# su - sonar
[sonar@Centos7-1 ~]$ /usr/local/sonarqube-7.1/bin/linux-x86-64/sonar.sh start
Starting SonarQube...
Started SonarQube.
查看服务是否启动
[sonar@Centos7-1 ~]$ netstat -lntp
