  • 【PostgreSQL-9.6.3】log参数的设置

    编辑数据目录中的postgresql.conf参数文件,我的数据目录是/usr/local/pgsql/data

    vi postgresql.conf

    找到如下内容:

    ...

    #------------------------------------------------------------------------------
    # ERROR REPORTING AND LOGGING
    #------------------------------------------------------------------------------

    # - Where to Log -

    #log_destination = 'stderr'             # Valid values are combinations of
                                            # stderr, csvlog, syslog, and eventlog,
                                            # depending on platform.  csvlog
                                            # requires logging_collector to be on.

    # This is used when logging to stderr:
    #logging_collector = off                # Enable capturing of stderr and csvlog
                                            # into log files. Required to be on for
                                            # csvlogs.
                                            # (change requires restart)

    # These are only used if logging_collector is on:
    #log_directory = 'pg_log'               # directory where log files are written,
                                            # can be absolute or relative to PGDATA
    #log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'        # log file name pattern,
                                            # can include strftime() escapes
    #log_file_mode = 0600                   # creation mode for log files,
                                            # begin with 0 to use octal notation
    #log_truncate_on_rotation = off         # If on, an existing log file with the

    #log_rotation_age = 1d                  # Automatic rotation of logfiles will
                                            # happen after that time.  0 disables.
    #log_rotation_size = 10MB               # Automatic rotation of logfiles will

    ...

    日志收集功能在大部分情况下是需要打开的,所以设置为:

    logging_collector = on

    日志目录可以使用默认目录,也可以自行修改,一般选择默认目录就可以了:

    log_directory = 'pg_log'

    日志文件模式,一般选择默认就可以:

    log_file_mode = 0600

    日志保存周期及切换方式可以采用如下几种方案:

    (1)每天生成新的日志文件

    log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'

    log_truncate_on_rotation = off

    log_rotation_age = 1d

    log_rotation_size = 0

    (2)每当日志文件满10M时,进行切换

    log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'

    log_truncate_on_rotation = off

    log_rotation_age = 0

    log_rotation_size = 10M

    (3)日志保存周期为7天,循环覆盖

    log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'

    log_truncate_on_rotation = on

    log_rotation_age = 1d

    log_rotation_size = 0
