3)复制pg_xlog下的所有文件到/storage0/database/postgres/archive目录下 4)启动Standby节点,完成Replication。 完成Streaming Replication配置。 启动pgAdmin,连接192.168.111.150节点,创建test数据库,刷新 192.168.111.151节点。可以看到在192.168.111.151上也生成了test数据库。

1.1、登录:sudo -u postgres psql 1.2、创建:postgres=#create role replica login replication encrypted password 'replica'; 2、修改认证文件:pg_hba.conf 添加如下配置: host all all 10.14.22..0/16 trust # 允许连接 host replication replica 10.14.22.0/16 trust # 允许replica用户复制本机数据 3、配置...
配置修改postgresql streaming replication 废话就不多说了,开始。。。 postgresql从9.0开始有流制复,这里录记一下贱制复的安装录记。 环境: redhat 5.5 64位 PG版本:9.1.2 master:192.168.1.168 slave:192.168.1.169 1.配置主机系统相干数参 1.1修改/etc/sysctl.conf...
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.
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,...
Again, this is needed to run pg_basebackup and the subsequent streaming connection. Even if you are using a traditional method to take the base backup, you still have to allow replication connections to stream the XLOG, so this step is mandatory. 一旦您的主服务器配置成功,您可以重新启动数据...
PostgreSQL Streaming Replication的FATAL ERROR 首先,通过代码,查看调用关系: libpqwalreceiver.c _PG_init 関数/** Module load callback*/void_PG_init(void) {/*Tell walreceiver how to reach us*/if(walrcv_connect != NULL || walrcv_receive != NULL ||walrcv_send!= NULL || walrcv_disconnect...
Logical replication:Great for streaming changes from the source to the target PostgreSQL instance in near real-time. This drastically reduces downtime and gives you breathing room for testing. Tools likepglogicalor built-inlogical replicationfeatures make this easier. ...
