我使用PHP建立ssl连接有一些奇怪的问题.
我有网络和数据库服务器.我两个都通过oPEnssl生成了证书.它们完全一样.

所以我试图使用mysql命令从webserver连接：

MysqL -h 10.1.1.1 -uroot -p
Password
Welcome to the MysqL monITor.  Commands end with ; or \g.
Your MysqL connection id is 71

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MysqL>

所以现在我想看看它是否真的是ssl：

MysqL> status;

所以我看到建立了连接.我写了一些PHP脚本来连接我的数据库：

<?PHP
ini_set ('error_reporting',E_ALL);
ini_set ('display_errors','1');
error_reporting (E_ALL|E_STRICT);

$db = MysqLi_init();
MysqLi_options ($db,MysqLI_OPT_SSL_VERIFY_SERVER_CERT,true);

$db->ssl_set('/etc/MysqL/newcerts/client-key-rsa.pem','/etc/MysqL/newcerts/client-cert.pem','/etc/MysqL/newcerts/ca-cert.pem',NULL,NULL);
$link = MysqLi_real_connect ($db,'10.1.1.1','root','xxxxxx','MysqL',3306,MysqLI_CLIENT_SSL);
if (!$link)
{
    die ('Connect error (' . MysqLi_connect_errno() . '): ' . MysqLi_connect_error() . "\n");
} else {
    $res = $db->query('SHOW TABLES;');
    print_r ($res);
    $db->close();
}
?>

但是现在当我在我的网络服务器上运行这个脚本时,我收到了这个错误：

[root@web-01 config]# PHP test.PHP

Warning: MysqLi_real_connect(): Unable to locate peer certificate CN in /home/extranet/app/config/test.PHP on line 10

Warning: MysqLi_real_connect(): Cannot connect to MysqL by using SSL in /home/extranet/app/config/test.PHP on line 10

Warning: MysqLi_real_connect(): [2002]  (trying to connect via tcp://10.1.1.1:3306) in /home/extranet/app/config/test.PHP on line 10

Warning: MysqLi_real_connect(): (HY000/2002):  in /home/extranet/app/config/test.PHP on line 10
Connect error (2002):

这太奇怪了.我试过MysqL_connet(),它有效……

有任何想法吗 ？？

我使用的是PHP 5.6.25

编辑：
当然,我还在我的网络服务器.my.cnf@L_126_50@中添加了一行：

[client]
port=3306
ssl-ca=/etc/MysqL/newcerts/ca-cert.pem
ssl-cert=/etc/MysqL/newcerts/client-cert.pem
ssl-key=/etc/MysqL/newcerts/client-key-rsa.pem

从webserver命令行也可以正常工作：

MysqL -h 10.1.1.1 -u root --password \
    --ssl \
    --ssl-ca /etc/MysqL/newcerts/ca-cert.pem \
    --ssl-cert /etc/MysqL/newcerts/client-cert.pem \
    --ssl-key /etc/MysqL/newcerts/client-key-rsa.pem \
