auditd 在轮换期间不压缩日志

审核不会压缩任何日志。也许这是一个配置问题。您能告诉我下面的配置中是什么原因导致的吗？

local_events = yes
write_logs = yes
log_file = /var/log/audit/audit.log
log_group = root
log_format = RAW
flush = INCREMENTAL_ASYNC
freq = 50
max_log_file = 100
num_logs = 5
priority_boost = 4
disp_qos = lossy
dispatcher = /sbin/audispd
name_format = NONE
##name = mydomain
max_log_file_action = keep_logs
space_left = 75
space_left_action = email
action_mail_acct = root
admin_space_left = 50
admin_space_left_action = SUSPEND
disk_full_action = SUSPEND
disk_error_action = SUSPEND
use_libwrap = yes
##tcp_listen_port =
tcp_listen_queue = 5
tcp_max_per_addr = 1
##tcp_client_ports = 1024-65535
tcp_client_max_idle = 0
enable_krb5 = no
krb5_principal = auditd
##krb5_key_file = /etc/audit/audit.key
distribute_network = no

auditd 无法压缩自己的日志，您需要为此设置 logrotate。欲了解更多信息，请查看：

或者 https://www.stigviewer.com/stig/vmware_vrealize_operations_manager_6.x_sles/2018-10-11/finding/V-88747

两者都有点过时，但你可以简单地替换service restart auditd为systemctl restart auditd

auditd.conf 所需的更改（默认情况下它会自行轮换文件，这不是我们想要的）：

max_log_file             =  0
max_log_file_action      =  ignore

logrotate 文件示例，例如/etc/logrotate.d/audit

/var/log/audit/*.log {
        weekly
        missingok
        compress
        #copytruncate
        rotate 30
        minsize 100k
        maxsize 200M
        postrotate
                touch /var/log/audit/audit.log ||:
                chmod 0600 /var/log/audit/audit.log ||:
                service auditd restart
        endscript
}
