我在將會話數據存儲在遠程memcache服務器上時遇到問題。這是我收到的錯誤：將會話數據存儲在memcache服務器上
[Wed Dec 14 07:33:18 2016] [error] [client 192.168.247.235] PHP Warning: Unknown: Failed to write session data (memcache). Please verify that the current setting of session.save_path is correct (tcp://192.168.247.111:11211) in Unknown on line 0
在同一臺服務器，如果我通過telnet嘗試它的工作原理：
[[email protected] ~]# telnet 192.168.247.111 11211
Trying 192.168.247.111...
Connected to 192.168.247.111.
Escape character is '^]'.
set test 0 100 3
xxx
STORED
get test
VALUE test 0 3
xxx
END
的php.ini：
session.save_handler=memcache
session.save_path="tcp://192.168.247.111:11211"
同樣的事情發生時，我在php.ini中使用memcached：
session.save_handler=memcached
session.save_path="192.168.247.111:11211"
just ab它會在error_log

php文件的詳細信息僅有3行：
<?
session_start();
$_SESSION['somekey'] = "someval";
print_r($_SESSION);
