旋转日志时出错

我对轮换有两个问题/var/log/message。以下是日志消息配置

# cat /etc/logrotate.d/logrotate-messages
/var/log/messages {
    daily
    rotate 7
    create
    dateext
    dateformat -%Y%m%d
    compress
    delaycompress
    notifempty
    nomail
    noolddir
    postrotate
        /bin/killall -HUP syslogd
    endscript
}

由于某种原因，旋转后，/var/log/messages没有任何后缀的文件没有消息，但最后一个日期的文件包含所有消息/var/log/messages-20200427

-rw-------. 1 root root 6.8M Apr 12 03:36 /var/log/messages-20200412.gz
-rw-------. 1 root root  41M Apr 19 03:30 /var/log/messages-20200417.gz
-rw-------. 1 root root  43M Apr 26 03:13 /var/log/messages-20200425.gz
-rw-------. 1 root root    0 Apr 27 03:47 /var/log/messages
-rw-------. 1 root root 3.6G Apr 30 13:15 /var/log/messages-20200427

当我手动运行时，我在旋转后只看到一个错误，如下所示。

#/sbin/logrotate -v /etc/logrotate.d/logrotate-messages
reading config file /etc/logrotate.d/logrotate-messages
Allocating hash table for state file, size 15360 B

Handling 1 logs

rotating pattern: /var/log/messages  after 1 days (7 rotations)
empty log files are not rotated, old logs are removed
considering log /var/log/messages
  log needs rotating
rotating log /var/log/messages, log->rotateCount is 7
Converted ' -%Y%m%d' -> '-%Y%m%d'
dateext suffix '-20200430'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
glob finding logs to compress failed
fscreate context set to system_u:object_r:var_log_t:s0
renaming /var/log/messages to /var/log/messages-20200430
creating new /var/log/messages mode = 0600 uid = 0 gid = 0
running postrotate script
syslogd: no process found
error: error running non-shared postrotate script for /var/log/messages of '/var/log/messages '
set default create context

写入文件的过程是

#fuser /var/log/messages-20200427
/var/log/messages-20200427: 41809
# ps -aef | grep 41809 | grep -v grep
root     41809     1  0 Apr24 ?        00:20:18 /usr/sbin/rsyslogd -n

不确定如何修复，非常感谢任何帮助。

您正尝试将 SIGHUP 发送到错误的进程：

/bin/killall -HUP syslogd

但

/usr/sbin/rsyslogd

所以你必须将其更改为

/bin/killall -HUP rsyslogd
