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.sample
所以我这样做:
egrep 'listen|port' /usr/local/Cellar/postgresql/9.0.4/share/postgresql/postgresql.conf.sample
#listen_addresses = 'localhost' # what IP address(es) to listen on;
#port = 5432 # (change requires restart)
# supported by the operating system:
# %r = remote host and port
所以我尝试了这个:
> cp /usr/local/Cellar/postgresql/9.0.4/share/postgresql/postgresql.conf.sample /usr/local/Cellar/postgresql/9.0.4/share/postgresql/postgresql.conf
> cp /usr/share/postgresql/postgresql.conf.sample /usr/share/postgresql/postgresql.conf
仍然得到相同的“服务器是否正在运行?” 信息。
sudo
,即sudo pg_ctl...
