Redhat 7では、logrotate圧縮はまったく機能しません。

私のlogrotate圧縮はまったく機能しません。ログの回転はファイルを回転しますが、まったく圧縮しません。私が犯した簡単な間違いを教えてください。これは logrotate -v /etc/logrotate.conf の出力です。

rotating pattern: /var/log/btmp  monthly (1 rotations)
empty log files are not rotated, old logs are removed
considering log /var/log/btmp
  log does not need rotating

rotating pattern: /tmp/app/stderr  419430400 bytes (1 rotations)
empty log files are not rotated, old logs are removed
considering log /tmp/app/stderr
  log needs rotating
rotating log /tmp/app/stderr, log->rotateCount is 1
dateext suffix '-20160603'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
glob finding logs to compress failed
glob finding old rotated logs failed
fscreate context set to unconfined_u:object_r:user_tmp_t:s0
renaming /tmp/app/stderr to /tmp/app/stderr-20160603
creating new /tmp/app/stderr mode = 0755 uid = 0 gid = 0
set default create context
[root@localhost app]# ls -l 
total 2103448

これは私のconfファイルlogrotate.confです。

# 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.

/tmp/app/stderr {
     missingok
     rotate 1
     daily
     size 400M
     compress
     su
}

delaycompress構成セクションに追加することで/var/log/問題が解決しました。

からman logrotate

delaycompress

      Postpone  compression of the previous log file to the next rota‐
      tion cycle.  This only has effect when used in combination  with
      compress.   It  can  be used when some program cannot be told to
      close its logfile and thus might continue writing to the  previ‐
      ous log file for some time.

興味深いことに、私の元の設定(directivesを除くdelaycompress)は以下から直接提供されますman logrotateweeklyに変更した場合を除くdaily)。

# sample logrotate configuration file
compress

/var/log/messages {
     rotate 5
     weekly
     postrotate
         /usr/bin/killall -HUP syslogd
     endscript
 }
