我已经安装了 logrotate 3.8.6 的 CentOS 7.4。我有一个自定义 logrotate 文件，/etc/logrotate.d/用于轮换安装在同一台机器上的 Tomcat（例如 catalina.out）上的一些日志。

/opt/test/apache-tomcat-8.5.15-client/logs/catalina.out {
copytruncate
daily
rotate 30 
olddir /opt/test/apache-tomcat-8.5.15-client/logs/backup
compress
missingok
maxsize 50M
dateext
dateformat .%Y-%m-%d
}

我希望日志每天轮换，或者如果大小达到 50MB。发生这种情况时，日志文件会被压缩并复制到备份文件夹中，并在被删除之前保留 30 天。

我已经使用以下命令在调试模式下手动运行 logrotate 并且没有显示错误（并且创建了预期的压缩日志文件）：

/usr/sbin/logrotate -d /etc/logrotate.d/openncp-tomcat-backoffice 2> /tmp/logrotate.debug

在/var/lib/logrotate/logrotate.status没有问题的情况下，文件显示为已旋转，但实际上并非如此：

"/var/log/yum.log" 2017-11-27-19:0:0
"/opt/test/apache-tomcat-8.5.15-server/logs/catalina.out" 2017-12-15-3:41:1
"/var/log/boot.log" 2017-12-15-3:41:1
"/var/log/up2date" 2017-11-27-19:0:0

我有默认值/etc/logrotate.conf：

# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# use date as a suffix of the rotated file
dateext

# uncomment this if you want your log files compressed
#compress

# RPM packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp and btmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    create 0664 root utmp
        minsize 1M
    rotate 1
}

/var/log/btmp {
    missingok
    monthly
    create 0600 root utmp
    rotate 1
}

# system-specific logs may be also be configured here.

我也有默认值/etc/cron.daily/logrotate：

#!/bin/sh

/usr/sbin/logrotate -s /var/lib/logrotate/logrotate.status /etc/logrotate.conf
EXITVALUE=$?
if [ $EXITVALUE != 0 ]; then
    /usr/bin/logger -t logrotate "ALERT exited abnormally with [$EXITVALUE]"
fi
exit 0

根据logrotate 联机帮助页：

maxsize size
    Log files are rotated when they grow bigger than size bytes even before the additionally specified time interval ( daily, weekly, monthly, or yearly). The related size option is similar except that it is mutually exclusive with the time interval options, and it causes log files to be rotated without regard for the last rotation time. When maxsize is used, both the size and timestamp of a log file are considered.

我注意到，到目前为止，日志还没有达到 50MB，而且几天过去了，没有任何轮换。

我要求您指导如何适当地配置它。

centos logrotate
