Question

我在ubuntu 12.04中使用postgres-xl。

当我尝试使用createuser temp，psql postgres，createdb newdb错误是

createdb: could not connect to database template1: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

我的设置是

  listen_addresses = 'localhost'
    port = 9999             
    max_connections = 100   
    unix_socket_directory = '/usr/local/pgsql'


# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:         127.0.0.1/32  
host    all             all             0.0.0.0/0            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     apple                                trust
#host    replication     apple        127.0.0.1/32            trust
#host    replication     apple        ::1/128                 trust

Answer 1

我想您正在尝试连接到在端口5432上运行的协调器：

Unix域套接字上的连接“/tmp/.s.PGSQL.5432”？

但是你的配置文件端口是9999

listen_addresses ='localhost'
     port = 9999
     max_connections = 100

你应该像这样运行createdb命令。数据库用户必须有权创建db。

./createdb --port=9999 --host=localhost --username=<USERNAME>

您收到的错误消息可能有很多可能的原因。根据{{1}}的建议，检查配置文件。

否则，我建议您使用pgxc_ctl命令行工具自动生成基本配置文件，以后可以更改/修改。

createuser temp，psql postgres和createdb newdb在postgres-xl中不起作用？
