CentOS6以下系统（含）使用watchtmp + cron来实现定时清理临时文件的效果，这点在CentOS7发生了变化，在CentOS7下，系统使用systemd管理易变与临时文件，与之相关的系统服务有3个： 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 相关的配置文件也有3个地方： /etc/tmpfiles.d/*.conf /run/tmpfiles.d/*.conf /usr/lib/tmpfiles.d/*.conf /tmp目录的清理规则主要取决于/usr/lib/tmpfiles.d/tmp.conf文件的设定，默认的配置内容为： # 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 10d # 清理/tmp下10天前的目录和文件 v /var/tmp 1777 root root 30d # 清理/var/tmp下30天前的目录和文件 # Exclude namespace mountpoints created with PrivateTmp=yes x /tmp/systemd-private-%b-* X...

Centos7添加nginx为系统服务；经过编译安装以及解决问题，Nginx 已经运行正常，但是此时 Nginx 并没有添加进系统服务。接下来会将 Nginx 添加进系统服务并且设置开机启动。让我们看一下操作步骤吧！ 1、添加系统服务文件 $ vi /usr/lib/systemd/system/nginx.service [Unit] Description=Nginx Web Server After=network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/usr/local/nginx/logs/nginx.pid ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf ExecReload=/usr/local/nginx/sbin/nginx -s reload ExecStop=/usr/local/nginx/sbin/nginx -s stop ExecQuit=/usr/local/nginx/sbin/nginx -s quit PrivateTmp=true [Install] WantedBy=multi-user.target 2、重新加载系统配置 $ systemctl daemon-reload 3、用系统命令启停nginx服务 $ systemctl stop nginx $ systemctl start nginx $ systemctl reload nginx $ systemctl restart nginx
