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; dofor x in $i;domkdir -p /tmp/session/$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 ];thensed -i 's#;session.save_path = /tmp#;session.save_path = /tmp＼nsession.save_path = 2;/tmp/session#g' /usr/local/php/lib/php.ini elseexit 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。
