linux系統(tǒng)下messages日志文件怎樣輪轉(zhuǎn)

ccjsj1

如題：

生成文件如下

messages  messages.1  messages.2  messages.3  messages.4

-rw------- 1 root root  72 10-17 04:02 messages
-rw------- 1 root root 222 10-11 08:25 messages.1
-rw------- 1 root root  72 10-03 04:02 messages.2
-rw------- 1 root root 222 10-01 05:10 messages.3
-rw------- 1 root root 222 09-20 20:55 messages.4

由哪個文件生成的輪轉(zhuǎn)文件（1-4），輪轉(zhuǎn)規(guī)則是什末呢？

    配置文件在

找到了，那末syslogtate是怎樣定時執(zhí)行的呢？

cat /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

# 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 -- we'll rotate them here
/var/log/wtmp {
    monthly
    minsize 1M
    create 0664 root utmp
    rotate 1
}

cat /etc/logrotate.d/syslog
/var/log/messages /var/log/secure /var/log/maillog /var/log/spooler /var/log/boot.log /var/log/cron {
    sharedscripts
    postrotate
        /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
        /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true
    endscript
}

    它實際上用的是crontab。。。樓主google下或者找男人問問。。相關(guān)資料很多的。。。。

BangBull

1. root # cat /etc/cron.daily/logrotate
   
2. #!/bin/sh
   
3. 
   
4. /usr/sbin/logrotate /etc/logrotate.conf
   
5. EXITVALUE=$?
   
6. if [ $EXITVALUE != 0 ]; then
   
7.     /usr/bin/logger -t logrotate "ALERT exited abnormally with [$EXITVALUE]"
   
8. fi
   
9. exit 0
