Question

我已经从此处下载了Windows版本的PostgreSQL：https://www.enterprisedb.com/products-services-training/pgbindownload

我解压缩了该文件，并执行了以下命令以运行服务器，并且该服务器在Windows 10中可以正常工作：

D:\postmaster_standalone\postgresql-11.0-2-windows-x64-binaries\pgsql\bin>initdb -D C:/Users/myuser/pgdataTest -U postgres -E UTF8

D:\postmaster_standalone\postgresql-11.0-2-windows-x64-binaries\pgsql\bin>pg_ctl -D C:/Users/myuser/pgdataTest start

postgres=#

在我的CentOS中，我用uname -m command检查了一下，它返回了x86_64。从上面的链接中，我下载了Linux x86-64版本10.6的二进制文件。

然后，我按照以下顺序在Windows中执行了类似的步骤，但是服务器未启动：

[cloudera@quickstart bin]$ initdb -D /home/cloudera/pgdata -U postgres -E UTF8 
The files belonging to this database system will be owned by user "cloudera".
This user must also own the server process.
-----
-----
The database cluster will be initialized with locale en_US.UTF-8.
Success. You can now start the database server using:

    postgres -D /home/cloudera/pgdata
or
    pg_ctl -D /home/cloudera/pgdata -l logfile start

[cloudera@quickstart bin]$ pg_ctl -D /home/cloudera/pgdata/ start
server starting
[cloudera@quickstart bin]$ psql 
psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
[cloudera@quickstart bin]$ psql -U postgres
psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

我犯错了吗？请帮助。

Answer 1

您使用的PostgreSQL二进制文件必须为unix_socket_directories使用更改后的默认值，并且启动服务器的用户无权在其中写入。

编辑/home/cloudera/pgdata/postgresql.conf并设置

unix_socket_directories = /tmp

或通过以下方式启动服务器

pg_ctl -D /home/cloudera/pgdata/ -o '-k /tmp' start

要连接，请使用

psql -h /tmp -U postgres -d postgres

没有安装的PostgreSQL在Windows中运行但服务器未在CentOS Linux中启动
