在數(shù)據(jù)目錄下編輯postgresql.conf文件，找到如下內(nèi)容：#listen_addresses = 'localhost'   # what IP address(es) to listen on;#port = 5432       # (change requires restart)listen_addresses表示要監(jiān)聽的地址，要讓網(wǎng)絡(luò)上的主機(jī)登錄這臺數(shù)據(jù)庫，需要把這個地址改成"*"，或者0.0.0.0。port表示監(jiān)聽的端口，可以不更改，修改這兩個參數(shù)后，需要重啟才能生效。#與數(shù)據(jù)庫Log相關(guān)的參數(shù)logging_collector = on #日志的收集，on表示打開log_directory = 'pg_log' #定義日志的收集目錄日志的切換和是否選擇覆蓋則可以使用如下幾種方案方案一：每天生產(chǎn)一個新的日志文件log_filename = ‘postgresql-%Y-%m-%d_%H%M%S.log'log_truncate_on_rotation = offlog_rotation_age = 1dlog_rotation_size = 0方案二：每當(dāng)日志寫滿一定的大?。ㄈ?0MB空間），則切換一個日志log_filename = ‘postgresql-%Y-%m-%d_%H%M%S.log'log_truncate_on_rotation = offlog_rotation_age = 0log_rotation_size = 10M方案三：只保留7天的日志，進(jìn)行循環(huán)覆蓋 log_filename = ‘postgresql-%a.log'log_truncate_on_rotation = offlog_rotation_age = 1dlog_rotation_size = 0
