How do common users increase the maximum number of files?

How can a common user increase the maximum number of files to run a program on the server yesterday? The error "java.net. socketException: Too program open files ". You can use ulimit-a to check that the value of open files is 1024. You just want to increase the value and run ulimit-n 4096, the result shows that "ulimit: open files: cannot modify limit: The operation is not allowed." It is not a change, but a common user can only change the size, but cannot change the size ..... you can change the root user as needed, but the root user can only change the root user. Then I searched the internet and found that www.2cto.com could be modified by modifying/etc/security/limits. to solve this problem, add two configurations in the conf file. the Java code * soft nofile 65535 * hard nofile 65535 requires the root user to have the permission to modify the file. After the change, the user logs on again, and then ulimit-a checks that the number of open files is 65535.
