如何在Mac OS X上启动PostgreSQL服务器?

最后更新:


我忘记了运行initdb命令。


</最终更新>


通过运行此命令


ps auxwww | grep postgres

我看到postgres没有运行


> ps auxwww | grep postgres

remcat          1789   0.0  0.0  2434892    480 s000  R+   11:28PM   0:00.00 grep postgres

这提出了一个问题:如何启动postgresql服务器?


更新:


>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

更新2:


触摸不成功,所以我改为这样做:


> mkdir /usr/local/var/postgres

> vi /usr/local/var/postgres/server.log

> ls /usr/local/var/postgres/          

server.log

但是,当我尝试启动Rails服务器时,仍然看到以下内容:


Is the server running on host "localhost" and accepting

TCP/IP connections on port 5432?

更新3:


> pg_ctl -D /usr/local/var/postgres status

pg_ctl: no server running

更新4:


我发现那里没有pg_hba.conf(只有pg_hba.conf.sample),所以我修改了示例并将其重命名(以删除.sample)。这里是内容:


 # IPv4 local connections:

 host    all             all             127.0.0.1/32           trust

 # IPv6 local connections:

 host    all             all             ::1/128                trust

但我不明白这一点:


> pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start     

server starting

> pg_ctl -D /usr/local/var/postgres status                                     

pg_ctl: no server running

也:


sudo find / -name postgresql.conf

find: /dev/fd/3: Not a directory

find: /dev/fd/4: Not a directory

更新5:


sudo pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

Password:

pg_ctl: cannot be run as root

Please log in (using, e.g., "su") as the (unprivileged) user that will own the server process.

更新6:


这似乎很奇怪:


> egrep 'listen|port' /usr/local/var/postgres/postgresql.conf

egrep: /usr/local/var/postgres/postgresql.conf: No such file or directory

不过,我确实这样做:


>sudo find / -name "*postgresql.conf*"

find: /dev/fd/3: Not a directory

find: /dev/fd/4: Not a directory

/usr/local/Cellar/postgresql/9.0.4/share/postgresql/postgresql.conf.sample

/usr/share/postgresql/postgresql.conf.sampl

该自制包管理器包括launchctl的Plist自动启动。有关更多信息,请运行brew info postgres。手动启动:pg_ctl -D /usr/local/var/postgres start手动停止:pg_ctl -D /usr/local/var/postgres stop自动启动:“要启动现在启动postgresql并在登录时重新启动:”brew services start postgresql是什么结果pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start?是什么结果pg_ctl -D /usr/local/var/postgres status?server.log中是否有任何错误消息?确保在pg_hba.conf中启用了tcp localhost连接:# IPv4 local connections:host&nbsp; &nbsp; all&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;all&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;127.0.0.1/32&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; trust检查postgresql.conf中的listen_addresses和端口:egrep 'listen|port' /usr/local/var/postgres/postgresql.conf#listen_addresses = 'localhost'&nbsp; &nbsp; &nbsp;# what IP address(es) to listen on;#port = 5432&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # (change requires restart)打扫干净Postgres很可能是通过Homebrew,Fink,MacPorts或EnterpriseDB安装程序安装的。检查以下命令的输出,以确定安装了哪个软件包管理器:brew && brew list|grep postgresfink && fink list|grep postgresport && port installed|grep postgres

如果要手动启动和停止postgresql(通过homebrew安装),最简单的方法是:brew services start postgresql和brew services stop postgresql
