php – MYSQLi和ssl连接到数据库服务器

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

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, NULL, 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文件中添加了一行:

[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 \

证书用户/组/权限

[root@web-01 newcerts]# ls -alZ
drwxr-xr-x root root ?                                .
drwxr-xr-x root root ?                                ..

-rw-r--r-- root root ?                                client-cert.pem
-rw-r--r-- root root ?                                client-key.pem
-rw-r--r-- root root ?                                client-key-rsa.pem
-rw-r--r-- root root ?                                client-req.pem
-rw-r--r-- root root ?                                server-cert.pem
-rw-r--r-- root root ?                                server-key.pem
-rw-r--r-- root root ?                                server-req.pem

SELinux被禁用:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted
我也面临同样的错误,我在推文下面做了并为我工作.

$link = mysqli_real_connect ($db, '10.1.1.1', 'root', 'xxxxxx', 'mysql', 3306, NULL, MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT);
