PHP設定session定期自動清理的例子

配置完成php後,預設php會將session產生到/tmp目錄下,導致/tmp目錄檔案很多,因此需要對session進行週期性清理:

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:www.t4x.org
# 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

定時任務:

[root@hz scripts]# echo '#This is a config php session BY:BYRD AT:2014-03-31' >>/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


備忘:因為此配置修改了php.ini因此需要重新啟動php進程。
