MySQL DB instance using RDS
---------------------------
Create a Mysql DB instance in AWS with default settings

DB   - sonardb
User/Password  - sonardbadmin/Sonar123


Create an AWS ECS instance (Atleast t2.small instance as sonarqube require 1 GB free memory )
login to the machine as ec2-user

Install Java and Mysql client
-----------------------------

sudo su -
sudo yum install mysql java-1.8* -y   //Community Edition
sudo amazon-linux-extras install java-openjdk11 //Dev edition 


Sonarqube Installation
----------------------
CD to /opt 
#wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-7.6.zip
#unzip sonarqube-7.6.zip
#mv sonarqube-7.6  sonarqube


#useradd sonaradmin
#passwd  sonaradmin
Sonar@admin123

Give the sonaradmin user the permission to run the sonarqube 
#chown -R sonaradmin:sonaradmin sonarqube

#mysql -h <AWS RDS instance service name> -u sonardbadmin -p
Password: Sonar123

MySQL>create database sonar CHARACTER SET utf8 COLLATE utf8_general_ci;

Create a local and remote user for sonarqube

MySQL> create user sonar@localhost identified by 'sonar';

MySQL > create user sonar@'%' identified by 'sonar';


Grant database access permission to sonar user

MySQL > grant all on sonar.* to sonar@localhost;

MySQL > grant all on sonar.* to sonar@'%';


Check whether the users and database created 

MySQL>use mysql
MySQL>show databases;
MySQL>select user from mysql.user;      
Make sure a user with name 'sonar' exists.

MySQL>FLUSH PRIVILEGES;
MySQL>QUIT

Configure Sonarqube to use the RDS instance
-------------------------------------------
#cd /opt/sonarqube/conf/
Update the DB details in sonar.properties file

Uncomment the below entries and input the DB details 

sonar.jdbc.username=sonardbadmin
sonar.jdbc.password=Sonar123
sonar.jdbc.url=<Replace the localhost with RDS DB instance name>  

sonar.web.context=/sonar


#>su - sonaradmin
sonaradmin@..>cd /opt/sonarqube/bin/linux-x86-64/
sonaradmin@..>./sonar.sh start
sonaradmin@..>./sonar.sh status


Register SonarQube at boot time (RedHat, CentOS, 64 bit):
sudo ln -s $SONAR_HOME/bin/linux-x86-64/sonar.sh /usr/bin/sonar
sudo chmod 755 /etc/init.d/sonar
sudo chkconfig --add sonar


Configure Reverse Proxy to route the request through 80



[root@ip-1...]# yum install epel-release
[root@ip-1...]# yum install nginx
[root@ip-1...]# sudo amazon-linux-extras install nginx1.12



Update the config file to proxy the connection to port 9000 to 80.


[root@ip-1...]# vi /etc/nginx/nginx.conf

# the server directive is nginx's virtual host directive
server {
  # port to listen on. Can also be set to an IP:PORT
  listen 80;
 
  # sets the domain[s] that this vhost server requests for
  server_name www.somecompany.com;   //Only if domain exists.
 
  location / {
    proxy_pass http://sonarhost:sonarport;
  }
}


[root@ip-linux-x86-64]# systemctl start nginx
[root@ip-linux-x86-64]# systemctl enable nginx
