I use the remote function to import data from remote servers in another clickhouse cluster, when I use the sql like :
INSERT INTO dataplugin.ods_stb_info_all_local
SELECT evtTime,evtCode,pVer,sdkVer,sdkSortId,stbID,manufacturer,model,cpName,macAddress,wifiMacAddress,romVer,apkVer,accessMethod,provinceCode,cityCode,now() as writeTime
FROM remote('xxx.xxx.xxx.xxx:19000','dataplugin','ods_stb_info_all','default','');
the error happens like this:
Code: 491. DB::Exception: Received from localhost:9000. DB::Exception: URL "xxx.xx.xxx.xxx:19000" is not allowed in config.xml.
I really can not understand what happened, I wish for someone's helps
It needs to define remote_url_allow_hosts-section in config.xml:
<yandex>
<!-- The list of hosts allowed to use in URL-related storage engines and table functions.
If this section is not present in configuration, all hosts are allowed.
-->
<remote_url_allow_hosts>
<!-- Host should be specified exactly as in URL. The name is checked before DNS resolution.
Example: "yandex.ru", "yandex.ru." and "www.yandex.ru" are different hosts.
If port is explicitly specified in URL, the host:port is checked as a whole.
If host specified here without port, any port with this host allowed.
"yandex.ru" -> "yandex.ru:443", "yandex.ru:80" etc. is allowed, but "yandex.ru:80" -> only "yandex.ru:80" is allowed.
If the host is specified as IP address, it is checked as specified in URL. Example: "[2a02:6b8:a::a]".
If there are redirects and support for redirects is enabled, every redirect (the Location field) is checked.
-->
<!-- Regular expression can be specified. RE2 engine is used for regexps.
Regexps are not aligned: don't forget to add ^ and $. Also don't forget to escape dot (.) metacharacter
(forgetting to do so is a common source of error).
-->
</remote_url_allow_hosts>
</yandex>
Example from test test_allowed_url_from_config:
<remote_url_allow_hosts>
<host>host:80</host>
<host_regexp>^[a-z]*\.ru$</host_regexp>
</remote_url_allow_hosts>
Steps:
open config.xm for editing
sudo nano /etc/clickhouse-server/config.d/config.xml
define the required settings
config.xml:
<yandex>
..
<remote_url_allow_hosts>..</remote_url_allow_hosts>
..
</yandex>
restart service to apply settings
sudo service clickhouse-server restart
Hey guys I'm trying to change in httpd.conf using ruby code 1.8.5 could you help me with it please
Apache configuration file The Apache configuration file must be configured specifically
for the server you have installed it on, i.e. the ServerName configuration item must be set to the IP address of the VM, not to 127.0.0.1 or any other generic address. TheServerAdmin configuration item must be set to cit470-sp2014-teamYOUR_TEAM_NUMBER#gmail.com. Create a gmail account with that name if you
have not done so already.
SSL All content must also be accessible using encrypted https versions of your URLs.
User directories Configure the server so that individual users can create their own web
sites by putting files in the public_html subdirectory of their home directory. These files should be available by both URLs of the form http://your_ip/~username and of the form http://your_ip/users/username. This may require that you create rewrite rules with mod_rewrite.

I am running WordPress on my localhost and trying to send request from a file of my plugin to another file called photos.php using ajax, I have correctly written the address of file in xmlhttp.open function but it runs into following error.
Not Found
The requested URL /wordpress/wp-admin/wp-content/plugins/myphoto/photos.php was not found on this server.
the actual address of the file is /wordpress/wp-content/plugins/myphoto/photos.php
xmlhttp.open("GET","wp-content/plugins/myphoto/photos.php?c="+option,true);
xmlhttp.send();
Try setting the absolute path:
xmlhttp.open("GET","/wordpress/wp-content/plugins/myphoto/photos.php?c="+option,true);
Your error implies you're using the relative path. Directory /wordpress/wp-admin/wp-content... does not exist.
i get this error while using Phpass 0.3 on my CI Controller
Message: is_readable() [function.is-readable]: open_basedir restriction in effect. File(/dev/urandom) is not within the allowed path(s): (/home/:/usr/lib/php:/usr/local/lib/php:/tmp)
Filename: phpass-0.3/PasswordHash.php
can someone tell me the problem is?
open_basedir is a directive defined in your php.ini file.
It is set to the lowest directory that you are allowed to access from a PHP script, usually your webroot.
Trying to access a file/directory further down the tree such as in /dev/ will then be dissallowed and you will get the message you have.
You will have to edit your php.ini and set open_basedir to your server root, which is generally a bad thing security-wise as if anyone managed to inject malicious code into your script they would have access to the entire system.
It would be safer to exececute a script (Perl, Python, etc) that lives in your web folder to read /dev/urandom if you really need to.
$output = `/scripts/get_urandom.pl`;
// Process output
Version 1.8 of phpass resolves this issue by suppressing the error:
Changes since revision 1.7: +2 -2 lines:
Prefixed is_readable() with "#" to suppress warning when open_basedir
restriction is in effect.

Fatal error: Call to undefined function mysql_connect() in C:\Apache\htdocs\test.php on line 2
(2 answers)
Closed 3 months ago.
I just installed PHP and Apache on my home PC. When I try to call function mysql_connect I get:
fatal error: call to undefined function mysql_connect.
I have loaded php.ini where I have uncommented lines extension=php_mysql.dll and
extension=php_mysqli.dll and changed extension directory to extension_dir = "C:\php\ext" - which is the directory where files php_mysql.dll and php_mysqli.dll are. How can I fix this problem?
Output of phpinfo():
http://jsfiddle.net/MMTwA/
After looking at your phpinfo() output, it appears the mysql extensions are not being loaded. I suspect you might be editing the wrong php.ini file (there might be multiple copies). Make sure you are editing the php file at C:\php\php.ini (also check to make sure there is no second copy in C:\Windows).
Also, you should check your Apache logs for errors (should be in the \logs\ directory in your Apache install.
If you haven't read the below, I would take a look at the comments section, because it seems like a lot of people experience quirks with setting this up. A few commenters offer solutions they used to get it working.
http://php.net/manual/en/install.windows.extensions.php
Another common solution seems to be to copy libmysql.dll and php_mysql.dll from c:\PHP to C:\Windows\System32.
Background about my (similar) problem:
I was asked to fix a PHP project, which made use of short tags. My WAMP server's PHP.ini had short_open_tag = off.
In order to run the project for the first time, I modified this setting to short_open_tag = off.
PROBLEM Surfaced:
Immediately after this change, all my mysql_connect() calls failed. It threw an error
fatal error: call to undefined function mysql_connect.
Solution:
Simply set short_open_tag = off.
My PC is running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes.
You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:
<?php
echo phpinfo();
?>
There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from
PHPIniDir 'c:\PHP\'
to
PHPIniDir 'c:\PHP'
Pay the attention that the last slash disturbed everything!
Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!
You have probably forgotten to restart apache/wamp/xamp/whatever webserver you use, you need to do that in order to make it work
Check your php.ini, I'm using Apache2.2 + php 5.3. and I had the same problem and after modify the php.ini in order to set the libraries directory of PHP, it worked correctly. The problem is the default extension_dir configuration value.
The default (and WRONG) value for my work enviroment is
; extension_dir="ext"
without any full path and commented with a semicolon.
There are two solution that worked fine for me.
1.- Including this line at php.ini file
extension_dir="X:/[PathToYourPHPDirectory]/ext
Where X: is your drive letter instalation (normally C: or D: )
2.- You can try to simply uncomment, deleting semicolon. Include the next line at php.ini file
extension_dir="ext"
Both ways worked fine for me but choose yours. Don't forget restart Apache before try again.
I hope this help you.
Hi I got this error because I left out the ampersand (&) in
; php.ini
error_reporting = E_ALL & ~E_DEPRECATED
Be sure you edited php.ini in /php folder, I lost all day to detect error and finally I found I edited php.ini in wrong location.
After change our php.ini, make sure to restart Apache web server.
Just for future reference, copying all these extension files to Windows/System or Windows/System32 is unnecessary.
All that is required is a copy of the php.ini file you edit in the PHP dir to copied to the root Windows dir.
phpinfo will clearly explain the below:
Configuration File (php.ini) Path C:\Windows
Logical sense will explain that php wants to load a config located in the Windows dir. :-)
One time I had a problem while using Off instead of off. And also check the pads one more time... The path has to be exact. Also add the following line to your environmental variable.
C:\your-apache-path\bin; C:\your-php-path\bin;C:\your-mysql-path\bin
If you are in Windows, right click My Computer, select properties, and navigate to the Advanced tab... (is Windows 7). Click on Advanced system settings first then select the Advanced tab and then Environmental variables. Select PATH and click on Edit. Make a copy of the string in a .txt file for back up (it might be empty)--- set your environmental variables... Log out and log back in.
Since mysql_connect This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.
by default xampp does not load it automatically
in your php.ini file you should uncomment
;; extension=php_mysql.dll
to
extension=php_mysql.dll
Then restart your apache you should be fine
This same problem drove me nuts (Windows 10, Apache 2.4, MySql 5.7). For some reason (likely PATH related), the .dlls would not load after uncommenting the correct exension dlls and extension_dir = "ext" in php.ini. After trying numerous things, I simply changed "ext" to use the full directory path. For example. extension_dir = "c:/phpinstall/ext" and it worked.
I think that you should use mysqli_connect instead of mysql_connect
