We have an application that is running on RHEL6/32 bit and RHEL6/64 bit. This application uses postgresql 8.4 from the beginning. Now, we want to provide support for this application on RHEL7/64 bit. RHEL7 comes with default postgresql 9.2 in its yum list and this is getting installed and its related services are running properly as well. But after installing postgresql 8.4 on RHEL7, it seems like the services are never running. Please find below the logs:

[root@linpubn218 postgres]# service postgresql status

Can postgresql 8.4 be installed on RHEL7, which is a systemd based OS? If yes, then what should I do to remove the above error?

/etc/init.d/postgresql-8.4宣言された変数があることに気付きました：

pidfile="/var/run/postmaster-${PGMAJORVERSION}.${PGPORT}.pid"

しかしsystemctl、PIDfileは同じではありません:

# systemctl show postgresql-8.4.service -p PIDFile PIDFile=/var/run/postmaster-8.4.pid

したがって、問題を修正するには、編集/etc/init.d/postgresql-8.4して置き換えます

pidfile="/var/run/postmaster-${PGMAJORVERSION}.${PGPORT}.pid"

と

pidfile="/var/run/postmaster-${PGMAJORVERSION}.pid"

次にリロードしsystemctlます：

# systemctl daemon-reload
#/etc/init.d/postgresql-8.4 start
Starting postgresql-8.4 (via systemctl):                   [  OK  ]

通常、パーミッションはこのタイプのエラーを引き起こしました

su - postgres

その後：

chmod 700 -R <data_directory>

また、SELinux も確認する必要があります。
