waiting for server to start…2020-09-18 15:00:21.403 CST [9609] LOG: listening on IPv4 address “0.0.0.0”, port 5432 2020-09-18 15:00:21.403 CST [9609] LOG: listening on IPv6 address “::”, port 5432 2020-09-18 15:00:21.405 CST [9609] LOG: listening on Unix socket “/tmp...
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。
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...
15. 16. 17. 18. 然后删除掉 postgres-02容器,重启启动: docker compose down postgres-02 docekr compose up -d postgres-02 1. 2. 另一个节点也是一样操作。 测试 在主节点的psql中执行:SELECT * FROM pg_stat_replication; postgres=# SELECT * FROM pg_stat_replication; ...
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,...
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'r...
PostgreSQL’s streaming replication gives you the freedom to pick how consistent your business requires the primary and standbys to be, by using bothsynchronous_commitandsynchronous_standby_names. How? Synchronous_commit Synchronous_commit, articulated in the documentationhere, allows you to d...
PostgreSQL高可用的核心在于其多种成熟的集群方案。主从复制(Streaming Replication)实现数据的实时同步,而逻辑复制(Logical Replication)则支持更灵活的数据分发。借助Patroni等管理工具,可以自动化故障检测与主备切换,大幅减少人工干预。 (拼课 wwit1024)
