随着时间的推移，Vaultwarden 日志文件会变得很大。使用 logrotate，我们可以定期轮换日志。

    1. sudo nano /etc/logrotate.d/bitwarden
    1. /var/log/bitwarden/*.log {
    2.     # Perform logrotation as the bitwarden user and group
    3.     su bitwarden bitwarden
    4.     # Rotate daily
    5.     daily
    6.     # Rotate when the size is bigger than 5MB
    7.     size 5M
    8.     # Compress old log files
    9.     compress
    10.     # Keep 4 rotations of log files before removing or mailing to the address specified in a mail directive
    11.     rotate 4
    12.     # Truncate the original log file in place after creating a copy
    13.     copytruncate
    14.     # Don't panic if not found
    15.     missingok
    16.     # Don't rotate log if file is empty
    17.     notifempty
    18.     # Add date instaed of number to rotated log file
    19.     dateext
    20.     # Date format of dateext
    21.     dateformat -%Y-%m-%d-%s
    22. }

    要在不手动解压缩的情况下查看压缩的日志文件：

    1. zcat logfile.gz
    2. zless logfile.gz
    3. zgrep -i keyword_search logfile.gz
