早上有同僚問了下CentOS7下/tmp目錄下檔案目錄保留多久,我記得CentOS6下預設好像是30天,CentOS7下不太确認,是以查了下:
<code>[root@kvm02 tmpfiles.d]</code><code># cd /usr/lib/tmpfiles.d/</code>
<code>[root@kvm02 tmpfiles.d]</code><code># ls</code>
<code>abrt.conf iscsi.conf net-snmp.conf rpcbind.conf spice-vdagentd.conf tuned.conf</code>
<code>cups.conf legacy.conf openlmi-storage.conf rpm.conf svnserve.conf var.conf</code>
<code>cups-lp.conf libselinux.conf pam.conf samba.conf systemd.conf x11.conf</code>
<code>etc.conf libstoragemgmt.conf ppp.conf sap.conf systemd-nologin.conf</code>
<code>gvfsd-fuse-tmpfiles.conf lvm2.conf python.conf selinux-policy.conf tmp.conf</code>
<code>initscripts.conf mdadm.conf radvd.conf setroubleshoot.conf tog-pegasus.conf</code>
<code>[root@kvm02 tmpfiles.d]</code><code># cat /usr/lib/tmpfiles.d/tmp.conf </code>

<code># Clear tmp directories separately, to make them easier to override</code>
<code>v</code> <code>/tmp</code> <code>1777 root root 10d</code>
<code>v</code> <code>/var/tmp</code> <code>1777 root root 30d</code>
<code># 預設保留時間變為了10天,如果這10天内沒做任何調整,估計會被幹掉</code>
<code># Exclude namespace mountpoints created with PrivateTmp=yes</code>
<code>x </code><code>/tmp/systemd-private-</code><code>%b-*</code>
<code>X </code><code>/tmp/systemd-private-</code><code>%b-*</code><code>/tmp</code>
<code>x </code><code>/var/tmp/systemd-private-</code><code>%b-*</code>
<code>X </code><code>/var/tmp/systemd-private-</code><code>%b-*</code><code>/tmp</code>
CentOS6的配置檔案是在/etc/cron.daily下,有興趣的朋友自己查下,網上資料比較多
