在 Ubuntu 系统中,getconf 命令通常用于查询系统配置参数。然而,getconf 并不直接提供查看系统日志级别的功能。系统日志级别通常由 syslog 或 rsyslog 等日志服务管理。
要查看系统日志级别,你可以尝试以下方法:
查看 syslog 配置文件(适用于较旧的系统):
sudo cat /etc/syslog.conf
或者
sudo nano /etc/syslog.conf
查看 rsyslog 配置文件(适用于较新的系统):
sudo cat /etc/rsyslog.conf
或者
sudo nano /etc/rsyslog.conf
在这些配置文件中,你可以找到类似于 LogLevel 的设置,它定义了日志的详细程度。例如:
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
kern.*                                                 /dev/console
# The authpriv file has restricted access.
authpriv.*                                              /var/log/secure
# Log all the mail messages in one place.
mail.*                                                  -/var/log/maillog
# Everyone gets emergency messages
*.emerg                                                 *
# Save news errors of level crit and higher in a special file.
uucp,news.crit                                          /var/log/spooler
# Everybody gets warning messages and above.
*.warn                                                  /var/log/messages
# Save boot messages also to boot.log
kern.*                                                  /boot/log/boot.log
# Find anything that requires root privileges
authpriv.*                                              /var/log/secure
authpriv.*                                              /var/log/auth.log
# Non-privileged users should not be able to read the password file.
# Use "authpriv" instead of "auth" so that the login program can
# access it when necessary.
auth.*                                                  /var/log/auth.log
# Save all the syslogd messages in one place.
*.info;mail.none;authpriv.none;cron.none              /var/log/syslog
# Save boot messages also to boot.log
kern.*                                                  /boot/log/boot.log
# The authpriv file has restricted access.
authpriv.*                                              /var/log/secure
authpriv.*                                              /var/log/auth.log
# Non-privileged users should not be able to read the password file.
# Use "authpriv" instead of "auth" so that the login program can
# access it when necessary.
auth.*                                                  /var/log/auth.log
# Save all the syslogd messages in one place.
*.info;mail.none;authpriv.none;cron.none              /var/log/syslog
journalctl 命令如果你使用的是 systemd,可以使用 journalctl 命令来查看系统日志,并通过 -b 选项指定查看当前启动的日志,或者不加 -b 选项查看所有日志。
sudo journalctl -b
或者
sudo journalctl
在 journalctl 的输出中,你可以看到不同级别的日志消息,包括 emerg、alert、crit、err、warning、notice 和 info。
如果你想查看特定服务的日志级别,可以查看该服务的配置文件。例如,对于 Apache HTTP 服务器,你可以查看 /etc/apache2/apache2.conf 或 /etc/apache2/httpd.conf 文件中的日志级别设置。
sudo cat /etc/apache2/apache2.conf | grep LogLevel
或者
sudo nano /etc/apache2/apache2.conf
通过这些方法,你应该能够找到并查看 Ubuntu 系统的日志级别设置。
