./RunInstaller-ignoreSysPrereqs
# Because Oracle does not support CentOS by default, the ignoreSysPrereqs parameter is added during installation to ignore the system check.
Tip:
1. Permission denied will be generated when runInstaller is executed.
Cd to this directory ll-a to check the file permissions. If you do not have the execution permission, use the following command to grant the execution permission
Chmod 755 userfile
2. the following error message is displayed during installation:
