卸载它们然后尝试使用http://openies.com/blog/install-openerp-odoo-9-on-ubuntu-server-14-04-lts/安装odoo 9

本教程.

但是当我试着执行命令时

createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo

然后它给出以下错误：

createuser: could not connect to database postgres: could not connect
to server: No such file or directory Is the server running locally
and accepting connections on Unix domain socket
“/var/run/postgresql/.s.PGsql.5432”?

sudo netstat -nltp | grep 5432没有显示任何结果.

的pg_hba.conf
