CentOS7下，系統使用systemd管理易變與臨時檔案，與之相關的系統服務有3個：

systemd-tmpfiles-setup.service ：Create Volatile Files and Directories
systemd-tmpfiles-setup-dev.service：Create static device nodes in /dev
systemd-tmpfiles-clean.service ：Cleanup of Temporary Directories
配置檔案也有3個地方：

/etc/tmpfiles.d/*.conf
/run/tmpfiles.d/*.conf
/usr/lib/tmpfiles.d/*.conf
/tmp目錄的清理規則主要取決於/usr/lib/tmpfiles.d/tmp.conf檔案的設定，預設的配置內容為：

# This file is part of systemd.
#
# systemd is free software; you can redistribute it and/or modify it
# under the terms of the GNU Lesser General Public License as published by
# the Free Software Foundation; either version 2.1 of the License, or
# (at your option) any later version.

# See tmpfiles.d(5) for details

# Clear tmp directories separately, to make them easier to override
v /tmp 1777 root root 7d
v /var/tmp 1777 root root 30d

# Exclude namespace mountpoints created with PrivateTmp=yes
x /tmp/systemd-private-%b-*
X /tmp/systemd-private-%b-*/tmp
x /var/tmp/systemd-private-%b-*
X /var/tmp/systemd-private-%b-*/tmp
如你不想讓系統自動清理/tmp下以tomcat開頭的目錄，那麼增加下面這條內容到配置檔案中即可：

x /tmp/tomcat.*
