Postgres 不写日志

Question

重新启动 PostgreSQL 后，日志文件已停止写入。

只出现以下日志。

FATAL:  lock file "postmaster.pid" already exists
HINT:  Is another postmaster (PID 1351) running in data directory "/var/lib/pipelinedb/9.5"?

Answer 1

您似乎已经有一个服务器实例运行。尝试连接 psql 或使用 ps aux | grep -i postgres 进行检查。如果另一个服务器实例是运行，请不要 kill -9，因为您可能会损坏数据。相反：

pg_ctl -D /var/lib/pipelinedb/9.5 stop -m fast

之后你应该正确启动你的服务器。
