If a Linux server does not have proper hostname entries in the /etc/hosts file, it is possible to get installer errors.
The installer carries out an import operation in order to load the core, minimal data into the repository database. This import operation can fail if the host is not configured.
If the import operation fails during installation, the installation will also fail. However, there should be an installation.log in the root of the installation folder to help debug the problem. The installation.log is located here:
<js-install>/installation.log
An improperly configured hosts file typically causes the log, or error messages displayed on the console, to contain error messages such as these:
Caused by: java.net.NoRouteToHostException: No route to host com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure ERROR Cache:145 - Unable to set localhost. This prevents creation of a GUID java.net.UnknownHostException org.quartz.SchedulerException: Couldn't get host name! |
To fix the /etc/hosts file:
| 1. | Include entries that look similar to these: |
127.0.0.1 localhost.localdomain
172.17.5.0 myhost.mydomain.com myhost
For instance:
127.0.0.1 localhost.localdomain localhost
172.17.5.0 myhost.jaspersoft.com myhost
| 2. | Also, you can double check the file /etc/sysconfig/network (if it exists). |
In this file it would be similar to the following:
HOSTNAME=myhost
| 3. | After fixing the /etc/hosts file, reinstall JasperReports Server. |
