如何判断我的 Postgresql 服务器是否正在运行?
我收到这条消息:
[~/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
检查正在运行的进程的最简单方法:
ps auxwww | grep postgres
并寻找一个看起来像这样的命令(你的版本可能不是 8.3):
/Library/PostgreSQL/8.3/bin/postgres -D /Library/PostgreSQL/8.3/data
要启动服务器,请执行以下操作:
/Library/PostgreSQL/8.3/bin/pg_ctl start -D /Library/PostgreSQL/8.3/data -l postgres.log
