Step 1: Create the user in master using whichever slave should connect for streaming the WALs. This user must have REPLICATION ROLE. PgSQL 1 2 3 CREATE USER replicator WITH REPLICATION ENCRYPTED PASSWORD 'replicator'; Step 2: The following parameters on the master are considered as mandatory wh...
在# replication privilege.下面添加一行,设置replication用户及权限 host replication postgres 192.168.0.1/24 trust 4)配置postgresql.conf 配置监听,修改listen_addresses = 'localhost' listen_addresses = '*' # what IP address(es) to listen on; 配置Primary Replication参数 wal_level = hot_standby max_wal...
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...
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...
When a full+incremental synchronization task is complete, the streaming replication slot created by the task in the source database is automatically deleted. Forcibly stop a task. You need to manually update the sequence value in the destination database. For details, see Forcibly Stopping Synchroni...
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 pglogical extension for PostgreSQL implements logical streaming replication, using a similar publish and subscribe built-in approach. The pglogical extension is suitable for the following use cases if: Your database size is greater than 100 GB. ...
