PostgreSQL Extension issues

aaP_demo1

I want to create extension for my database using postgis. but it is not able to due to these errors both from command line and interface:

# CREATE EXTENSION IF NOT EXISTS "postgis";
ERROR:  extension "postgis" is not available
DETAIL:  Could not open extension control file "/www/server/pgsql/share/extension/postgis.control": No such file or directory.
HINT:  The extension must first be installed on the system where PostgreSQL is running.

Please kindly help what should I need to enable this?

I installed it using command:

sudo dnf install -y geos-devel proj-devel protobuf-c-devel
wget https://download.osgeo.org/postgis/source/postgis-3.5.3.tar.gz
tar -xvzf postgis-3.5.3.tar.gz
cd postgis-3.5.3
./configure --with-pgconfig=/www/server/pgsql/bin/pg_config --prefix=/www/server/pgsql/extension --with-geosconfig=/usr/bin/geos-config --with-projdir=/usr/include/proj --with-protobuf=/usr/include/protobuf-c --without-raster
make
make install
