yes I do have a righ systemd service file named 'postgresql-11' and its located /usr/lib/systemd/system/
Here what I did so far aftermake install. mkdir /usr/local/pgsql/log Run ./usr/local/pgsql/bin/pg_ctl –D/postgres_data/pgsql/data –l /usr/local/pgsql/log/logfile start psql in the psql shell psql# create user replicareplication login encrypted password ‘replicauser@’; psql# alter user postgrespassword ‘password@’; configure postgresql.conf: port = 5432 unix_socket_directorys = ’tmp’ max_files_per_process = 1000 listen_addresses = ‘localhost,192.168.2.122 ‘ à (master-server-ip) wal_level = replica max_replication_slots = 10 archive_mode = on archive_command = ‘cp –I %p/u02/postgres/main/archive/%f’ max_wal_senders = 10 wal_keep_segments = 64 for pg_hba.conf, I added: local all postgres md5 à authenticate postgres host replication replica 192.##.##.##/32 md5 à master-server host replication replica 192.##.##.##/32 md5 à slave-server $ mkdir –p/u02/postgres/main/archive $ systemctl restart postgresql === AUTHENTICATING FORorg.freedesktop.systemd1.manage-units === Autehtication is required tomanage system services or units.

The problem I think but not sureI am right, I found there’s another source on /usr/pgql-11/bin existed on theserver. When the SA installed the OS Patch, the server hadpostgres-9.6. I can run any date for Postgresql 11. He applied OSPatches updated, removed 9.6 and yum the postgresql11-11.1-1PGDG.rhel7.x86_64.rpmsuccessful, configure, make and make install and start the postgresql service without error until the configuration of pg_hba.conf and postgresql.conf. The restart service failed. Wonder if I can remove /usr/pgql-11 or not but not sure whichone is the corrected binaries. Comparing with the single node postgresserver I did last year, the /usr/local/pgsql sounds convinced right binariesone but /usr/pgsql-11 have more functions.
