Postgres數據庫本地安裝/運行

Question

試圖在OSX Mountain Lion上設置Postgres/PostGIS以與Django一起使用。然而，有些事情是錯誤的，我不知道如何解決它。

$ createdb geo 
createdb: 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/pgsql_socket/.s.PGSQL.5432"? 

$ postgres -D /usr/local/var/postgres 
FATAL: lock file "postmaster.pid" already exists 
HINT: Is another postmaster (PID 221) running in data directory "/usr/local/var/postgres"? 

$ pg_ctl -D /usr/local/var/postgres -l logfile start 
pg_ctl: another server might be running; trying to start server anyway 
server starting 

然後，我發現this gist說，如何解決它在獅子。然而，它並沒有爲我工作：

$ kill -9 221 
$ pg_ctl -D /usr/local/var/postgres stop 
waiting for server to shut down.... done 
server stopped 

$ pg_ctl -D /usr/local/var/postgres start 
pg_ctl: another server might be running; trying to start server anyway 
server starting 
FATAL: lock file "postmaster.pid" already exists 
HINT: Is another postmaster (PID 1436) running in data directory "/usr/local/var/postgres"? 

的另一種嘗試：

$ cd /usr/local/var/postgres 
$ mv postmaster.pid postmaster.backup 
$ pg_ctl -D /usr/local/var/postgres start 
server starting 

$ LOG: could not bind IPv6 socket: Address already in use 
HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry. 
LOG: could not bind IPv4 socket: Address already in use 
HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry. 
LOG: could not bind IPv6 socket: Address already in use 
HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry. 
WARNING: could not create listen socket for "localhost" 
FATAL: could not create any TCP/IP sockets 

有沒有人成功地做到了這一點與美洲獅？如果是這樣，我錯過了什麼？感謝您對此問題的幫助！

此消息：

CREATEDB：無法連接到數據庫的Postgres：無法連接到 服務器：沒有這樣的文件或目錄 是在本地運行和驗收Unix域套接字 連接服務器「/ VAR/pgsql_socket/.s.PGSQL.5432" ？

表明你的PostgreSQL服務器不使用/var/pgsql_socket作爲其Unix域套接字目錄，這是在服務器和客戶端之間的會合點。這很常見，因爲只有Apple發佈的PostgreSQL和OSX服務器使用該路徑。順便說一下，這就是爲什麼Apple提供的createdb命令會嘗試連接到Apple配置的服務器。

從這一點出發，有很多不同的解決方案可以解決這個問題，但更明顯的是使用PostgreSQL安裝附帶的createdb命令，而不是系統中預安裝的命令。

如果你需要進一步的幫助，你應該指定你安裝PostgreSQL的方式，因爲有很多不同的包提供它，並且它們都使用不同的路徑來避免相互之間的踐踏。

如果使用BREW，我建議應用在superuser.com答案： How should I set the PATH variable on my Mac so the Hombrew-installed tools are found?

想必你指的是Postgres的+ PostGIS的教程的作者已經改變它很早以前就忘記在他的文本中提及它。

完成後，命令which createdb應返回/usr/local/bin/psql，這是自制軟件版本，而不是原始版本/usr/bin/psql，它是Apple版本。
