配置完成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 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 {} \;
#find /tmp/session -amin +180 | xargs rm -f
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

[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;

for x in $i;

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 {} \;

#find /tmp/session -amin +180 | xargs rm -f

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

定时任务：

[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
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
