According to the method on the internet, install RED5 after JRE is installed in Ubuntu, open the test page, and use it again. So I put the program openmeetings to the webapps of RED5 and restarted RED5. As a result, the test page could not be opened, and the OM could not be opened. I tried it multiple times, including reinstalling JRE and RED5. Finally found a feasible way to put $ RED5_HOME \ webapps \ xmlcrm \ WEB-INF \ web. xml

If you delete or comment out the above content, the 404 error will not occur.
Of course, the premise for solving this problem is that JRE and RED5 are correctly installed, MYSQL is running normally, and the configuration in OPENMEETINGS is also correct.
For example, if you want to create an empty database on MYSQL
Jdbc: mysql: // localhost/openmeetings
Change the database name to "dbc: mysql: // localhost: 3306/". Do not forget the MYSQL connection user and password.
