and UI

To make the Abiquo API use the virtual IP, log in to the server and do the following steps:

1. Go to the configuration folder:

   Code Block
   cd /opt/abiquo/tomcat/conf/Catalina/localhost/

2. Edit the api.xml file

3. Remove configuration that uses the services nodes:
   driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://ip1.example.com:3306,ip2.example.com:3306,ip3.example.com:3306/kinton?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8"/>

4. Add the virtual IP configuration:
   driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://"VirtualIP":3306/kinton?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8"/>Check the default configuration in this format.

   Code Block

   <Context> <Resource name="jdbc/abiquoDB" auth="Container" type="javax.sql.DataSource" factory="com.zaxxer.hikari.HikariJNDIFactory" dataSourceClassName="org.mariadb.jdbc.MariaDbDataSource" connectionTimeout="120000" maximumPoolSize="100" username="${server.database.username}" password="${server.database.password}" dataSource.url="jdbc:mariadb://${server.database.host}:${server.database.port}/kinton" /> </Context>

5. Remove the ${server.database.host} and replace it with the virtual IP

   Code Block
   dataSource.url="jdbc:mariadb://${virtual.ip}:${database.port}/kinton"

6. Restart the tomcat service

   Code Block
   service abiquo-tomcat restart
