docker pull postgres 2. 创建并运行主节点容器 接下来,创建一个Docker容器作为PostgreSQL的主节点。使用以下命令: bash docker run -d --name pg-primary \ -e POSTGRES_PASSWORD=mysecretpassword \ -v pgdata:/var/lib/postgresql/data \ -p 5432:5
dockerexec-it pg-primarypsql-U postgres-c "SELECT * FROM pg_create_physical_replication_slot('standby_slot');" 记下返回的复制槽名称,然后在从节点上设置复制: dockerexec-it pg-standby psql-U replicator-h pg-primary-c "CREATE DATABASE mydb WITH TEMPLATE = template0 ENCODING = 'UTF8' ...

update pg_database set encoding=pg_char_to_encoding('UTF8') where datname='postgres'; 方法二:修改模板库编码,一劳永逸。 # 修改模板库template1编码, 同理可修改 template0 update pg_database set (encoding, datctype, datcollate)=(6, 'en_US.UTF8','en_US.UTF8') where datname = 'templa...
dockerexec-it pg-primarypsql-U postgres-c "ALTER SYSTEM SET wal_level TO replica;" docker restart pg-primary 这段命令设置了最大WAL发送者数量(max_wal_senders)和WAL级别(wal_level)。 接下来,创建从节点容器,并指定主节点的连接信息:
