@Write at the beginning: after testing, this kind of problem occurs when centos8 installs Oracle 11g R2

@There will also be no response after lsnrctl start. After checking the lsnrctl file, it is found that the file is also 0kb

@It may be a compatibility problem. It is recommended to install Oracle help center with the system recommended by Oracle
