这篇文章主要介绍了php中session定期自动清理的方法，如何设置php实现session定期自动清理，本文会给大家详细介绍，需要的朋友可以参考下
配置完成php/2013102659340.html">php后默认php会将session生成到/tmp目录下，导致/tmp目录文件很多，因此需要对session进行定期的清理。
修改php.ini：
[root@hz scripts]# grep "session.save_path = " /usr/local/php/lib/php.ini ; session.save_path = "N;/path" ; session.save_path = "N;MODE;/path" ;session.save_path = "/tmp" session.save_path = "2;/tmp/session" [root@hz ~]# cat /byrd/script/Cleartmpsen.sh #!/bin/bash # Version:1.0 # Author:Byrd # Site: # Contact:root#t4x.org # This is script will clear php session before 3 hours. i="0 1 2 3 4 5 6 7 8 9 a b c d e f" for byrd in $i; do for x in $i; do mkdir -p /tmp/session/$byrd/$x; done; done chown -R bywww:bywww /tmp/session chmod -R 1777 /tmp/session find /tmp/session -amin +180 -exec rm -rf {} ＼; if [ `grep 'session.save_path =' /usr/local/php/lib/php.ini | wc -l` -eq 3 ];then sed -i 's#;session.save_path = "/tmp"#;session.save_path = "/tmp"＼nsession.save_path = "2;/tmp/session"#g' /usr/local/php/lib/php.ini else exit 1 fi 定时任务： [root@hz scripts]# echo '#This is a config php session BY:BYRD AT:2015-11-12' >>/var/spool/cron/root [root@hz scripts]# echo '0 3 * * 0 /bin/bash /byrd/scripts/spehspsion.sh >/dev/null 2>&1' >>/var/spool/cron/root
备注：因为此配置修改了php.ini因此需要重新启动php进程。
