os: centos 7.4.1708
db: postgresql 11.8
Slony-I: 2.2.8
Slony-I is a “master to multiple slaves” replication system for PostgreSQL supporting cascading (e.g. - a node can feed another node which feeds another node…) and failover.
個人猜測 Slony-I 是 postgresql stream replication 出現之前比較流行的複製工具。
查看官網時發現 Slony-I 有幾點優勢
-
You need to interact between PostgreSQL versions. Slony (and similar systems like Londiste and Bucardo) can cope with having nodes running different versions of PostgreSQL.
WAL-based replication requires that all databases use identical versions of PostgreSQL, running on identical architectures. -
You only want to replicate parts of the changes that are going on.
WAL-based replication duplicates absolutely everything. -
You need for there to be extra behaviours taking place on subscribers, for instance, populating cache management information.
WAL-based replication duplicates absolutely everything, and nothing extra that changes data can run on a WAL-based replica.

這3個節點都需要安裝 postgresql 11 及 Slony-I
