The script given by Mr. Ye.

During the trial operation of an application system, the web end often exits. In order to ensure the emergency response of the system, the WEB end is deployed into 5 nodes, which are called zjgpwebnode1~5, and the monitoring process is executed:

1. Create a monitoring execution script file / home/monitor.sh, which contains the following contents:

Exit

Please note that the file must be edited in UltraEdit, and must be saved in unix format, mainly because of the enter newline character, otherwise the "syntax error: unexpected end of file" error is reported.

In the actual execution, it is found that when the crond system is used to plan the task, the environment variables are not consistent with the original root user login, resulting in garbled code in the system, so the environment variables needed for the operation of the business system are added to the script.

2. After creating the monitor.sh file, you must add the execution task to the scheduled task:

Execute: crontab-e, add

* / 20 * / home/monitor.sh

Note: it means to execute the monitoring program monitor.sh every 20 minutes.

3. Restart the scheduled task program after adding to make the scheduled task effective:

/ sbin/service crond restart
