如何在没有安装pg_receivewal服务器的情况下用pg_basebackup和PostgreSQL安装Barman？

Question

按照正式文件，只需要用yum或apt直接安装酒保：

http://docs.pgbarman.org/release/2.10/#installation

无需在酒吧服务员服务器上安装PostgreSQL服务器。

但是为了使用barman，这两个库是必需的：pg_receivewal和pg_basebackup。如果安装/usr/pgsql-10/bin/服务器，则它们位于路径PostgreSQL中。

如何在不安装PostgreSQL服务器的情况下完成它们？反正有吗？

Answer 1

实际上，给定的URL还在系统需求部分中表示：

>= /UnixPython3.4Python模块: argh >= 0.21.2 psycopg2 >= 2.4.2 Python setuptools PostgreSQL >= 8.3 rsync >= 3.0.4 ( PostgreSQL >= 9.2可选)

看起来您需要安装PostgreSQL服务器。

Answer 2

我在PostgreSQL客户端10上做了一个CentOS 7测试：

# yum info postgresql10

Description : PostgreSQL is an advanced Object-Relational database management system (DBMS).
            : The base postgresql package contains the client programs that you'll need to
            : access a PostgreSQL DBMS server, as well as HTML documentation for the whole
            : system.  These client programs can be located on the same machine as the
            : PostgreSQL server, or on a remote machine that accesses a PostgreSQL server
            : over a network connection.  The PostgreSQL server can be found in the
            : postgresql10-server sub-package.
            : 
            : If you want to manipulate a PostgreSQL database on a local or remote PostgreSQL
            : server, you need this package. You also need to install this package
            : if you're installing the postgresql10-server package.

它有以下可执行文件

这意味着应该可以只为barman安装PostgreSQL客户端。
