Modify 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 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 scheduled task: [root @ hz scripts] # echo '# This is a config php session BY: byrd: 2015-11-12 '>/var/spool/cron/root [root @ hz scripts] # echo '0 3 ** 0/bin/bash/byrd/scripts/speheat Sion. sh>/dev/null 2> & 1'>/var/spool/cron/root
