无法在 RHEL 7.6 上启动监听器 oracle 12c

Question

I installed Oracle Database on RHEL.7.6. However, after restart server, I cannot startup listener with command though Oracle Instance already been started. :

lsnrctl start

It shows:

System parameter file is /u01/app/oracle/product/12.2.0/db1/network/admin/listener.ora
Log messages written to /u01/app/oracle/diag/tnslsnr/hungnv-fico1/listener/alert/log.xml
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=0.0.0.0)(PORT=1521)))
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521)))
TNS-01155: Incorrectly specified SID_LIST_LISTENER parameter in LISTENER.ORA
 NL-00305: the specified path name does not exist

This is my LISTENER.ORA file

SID_LIST_LISTENER= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=orcl) (ORACLE_HOME=$ORACLE_BASE/product/12.2.0/db1)(SERVICE_NAME=orcl) ) )

My first thinking is that I was properly set the path wrongly. However, I've tried to:

echo $ORACLE_HOME
/u01/app/oracle/product/12.2.0/db1

Any idea for this?

Don't use the variable in the LISTENER.ORA file. Specify the absolute path.

SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(GLOBAL_DBNAME=orcl)(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db1)(SERVICE_NAME=orcl)))
