Troubleshooting steps for FineBI startup failure

1.1 Problem description

Sometimes due to various complicated situations, users cannot successfully start BI server after installation.

1.2 Solutions

In general, there are the following reasons for the failure to start successfully, as follows:

The following sections describe in detail how to troubleshoot and deal with them.

2.1 Start BI with administrator privileges

Confirm whether to start BI with administrator privileges , if not, you need to stop the process and start again with administrator privileges. The Windows system is shown in the following figure:

2.2 Check if BI repeatedly starts two threads

1) Enter the command  ps -ef|grep java to check how many threads are started by BI under the current path, as shown in the following figure:

2) If there are multiple threads, all of them will end, enter kill -9 process number , as shown in the following figure:

2.3 Check the port occupancy

Note: The port number can only be occupied by one process.

1) Use the lsof -i: port number command to check whether the current port is occupied. If the following figure is shown, it means that the port is not occupied:

Note: If the error-bash: lsof-i:xx: command not foundis reported, you need to enter the command yum install lsof to use the lsof command.

As shown in the figure below, it means that the java application with process ID 8152 occupies port 80:

2) The port number can only be occupied by one process. If the current port number is already occupied, you need to adjust the port number of the BI server to an unoccupied port number. For details, see: Tomcat port configuration , how to modify the FineBI port number  .

2.4 Check if there are multiple projects/no projects in the webapps directory

Enter the BI installation directory and check whether there are multiple webroot files in the%FineBI%\webapps directory . If not, you need to place the installed webroot files under webapps, as shown in the following figure:

Note: The backup files are stored in a compressed folder, or copy the backup files to a directory other than the project location to ensure that there is only one project named webroot in the web container

2.5 db.lck file error

Windows uses other tools to open the FineDB database and it is not closed, check whether there is other software connected to the FineDB built-in database, if so, close the project and restart BI.

2.6 检查 Linux 文件权限

If the project cannot be started, open fanruan.logunder %FineBI%/logs , and the log reports an error of permission denied  . You need to enter the command chmod -R 777 for the file root directory permission, and then restart it, as shown in the following figure:

2.7

 Insufficient free disk space

If the project cannot be started, open the fanruan.log log under%FineBI%/logs and report an error: insufficient disk space.

Use the df -h command to check the current disk size of each partition, as shown in the following figure:

Use the command du -sh * to view the size of each folder in the current directory, as shown in the following figure:

Clean up unnecessary files.
