psql
已成功安装在我的 Linux 环境(Ubuntu)上,但使用psql
命令时我得到以下信息
psql: error: could not connect to server: 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"?
我已经尝试过以前的解决方案,但没有一个有效。服务器状态也未显示,日志文件为空,并且某些命令要求输入我从未设置的密码。
输出为dkpg -l | grep postgres
