What is PostgreSQL streaming replication? PostgreSQL streaming replication is a process that replicates data from a primary PostgreSQL database to one or more standby databases in real-time, ensuring that these standby databases mirror the primary database accurately. This replication method ensures high...
PostgreSQL使用了两种方式传输预写日志:存档式(archive)和流式(streaming)。 存档式复制的原理是主服务器将预写日志主动拷贝到一个安全的位置(可以直接到备用服务器,也可以是第三台服务器),同时备用服务器定期扫描这个位置,并将预写日志拷贝到备用服务器端然后再回放。这样即使主服务器崩溃了,备用服务器也可以从这个...
PostgreSQL: 9.1.2 版本以上才支持Streaming Replication。 1. 环境规划 Primary和Standby节点最好有相同的环境。 2. 安装PostgreSQL 1)在Primary和Standy节点上安装PostgreSQL软件,安装路径为/opt/pgsql 2)设置postgres用户的环境变量 PGHOME=/opt/pgsql PGDATA=/home/postgres/main PATH=$PG_HOME/bin:$PATH:$HOM...

Streaming replication is a core utility of PostgreSQL introduced in version 9.0. Streaming replication allows a standby server to stay more up-to-date than is possible with file-based log shipping. The standby connects to the primary, which streams WAL records to the standby as they're...
postgresql安装及Streaming_Replication配置1P2S 这篇记录文档是因为项目需要搭建postgres环境,并要求具有一定的可靠性.所以我在搭建这个环境的同时把步骤及命令记录下来的.感兴趣的朋友基本上复制粘贴这些命令就可以完成StreamingReplication的环境建设.因为我并没有为每个命令的目的性进行解释,所以为了明确每个命令的目的性,...
