[[email protected] mnt]# php-m |grep memcache # # # can see PHP does not support memcached

[Email protected] ~]# cd/mnt/

[[email protected] mnt]# ls

Memcache-2.2.5.tgz

[Email protected] mnt]# tar-zxf memcache-2.2.5.tgz # # #解压 tar zxf memcache-2.2.5.tgz

[Email protected] mnt]# CD memcache-2.2.5 # # #进入解压目录

[[email protected] memcache-2.2.5]# ls

[Email protected] memcache-2.2.5]# Phpize # #会自动生成configure
