Question

我遇到在远程memcache服务器上存储会话数据的问题。这是我得到的错误：

[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

在同一台服务器上，如果我尝试使用telnet，它可以工作：

[root@centos ~]# 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"

当我在php.ini中使用memcached时会发生同样的事情：

session.save_handler=memcached
session.save_path="192.168.247.111:11211"

在error_log中提供更多信息

php文件只有3行：

<?
session_start();
$_SESSION['somekey'] = "someval";
print_r($_SESSION);

经过几天的测试和谷歌搜索后，我发现SElinux就是问题所在。禁用后，一切都开始工作了。
