linux中可以使用logrotate 用来进行日志的管理

logrotate的默认配置文件为 /etc/logrotate.conf

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

# keep 9 weeks worth of backlogs
rotate 9

# 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 9
}

/var/log/btmp {
    missingok
    monthly
    create 0600 root utmp
    rotate 9
}

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

注意到其中有一个 include，它包含了/etc/logrotate.d/目录

所以可以将自定义配置放入到该目录下

当系统（使用crontab）或者手动调用logrotate /etc/logrotate.conf 时候，会自动调用/etc/logrotate.d/目录下的所有配置文件，同时，该目录中的配置文件会继承到/etc/logrotate.conf 中的全局参数

而手动调用 logrotate /etc/logrotate.d/XXX 的时候， XXX并不能继承到 /etc/logrotate.conf 中定义的全局变量
