我安裝了Centos 7,64位。安裝postgresql-9.4。 用命令初始化PostgreSQL的centos 7 postgresql未啓動
/usr/pgsql-9.4/bin/postgresql94-setup initdb
然後用這個命令啓動PostgreSQL的
systemctl start postgresql-9.4
,並顯示錯誤是這樣的:
service failed because the control process exited with error code. See "systemctl status postgresql-9.4.service" and "journalctl -xe" for details.
輸入的命令
systemctl status postgresql-9.4.service
● postgresql-9.4.service - PostgreSQL 9.4 database server
