如何判断我的Postgresql服务器是否正在运行?如何检查PostgreSQL服务器的状态Mac OS X
我得到这个消息:
[~/dev/working/sw] sudo bundle exec rake db:migrate
rake aborted!
could not connect to server: Connection refused
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
更新:
> which postgres
/usr/local/bin/postgres
> pg_ctl -D /usr/local/bin/postgres -l /usr/local/bin/postgres/server.log start
pg_ctl: could not open PID file "/usr/local/bin/postgres/postmaster.pid": Not a directory
更新2:
>pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
server starting
sh: /usr/local/var/postgres/server.log: No such file or directory
您还应该在Mac OS/X上寻找多个版本的postgres。如果你已经通过homebrew安装了postgres,那么当你的路径设置不正确时,你可以得到上述错误 - 我只是意外地欺骗了我的路径,一切开始使用postgres的系统安装,直到我调整路径使用brew安装 –
