我尝试psql时出现Postgresql错误

Question

我收到此错误，

psql: 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"?

问题是什么？我在Ubuntu 17.04 x64上使用postgresql 9.6

Answer 1

首先启动服务器：

../ bin / pg_ctl start

然后连接到数据库

psql dbname
