Thanks for you plugin set, first of all.
My environment CentOS 7, MySQL 5.5, plugin lib_mysqludf_sys has installed and works properly.
But I can't pass a variable from trigger to cmd - may be a specific wrapper is needed ?
Please, see the trigger below
AFTER INSERT ON trig_test
FOR EACH ROW
BEGIN
DECLARE cmd CHAR(255);
DECLARE result CHAR(255);
DECLARE var INT;
SET @var = (SELECT MAX(ID) FROM trig_test) ;
-- // this line does not work, tested echo @var, echo "@var" etc - or empty or 0
SET cmd = CONCAT('echo "@var" >> /test/mysqltrigger.txt');
SET result = sys_exec(cmd);
-- // this line work OK
SET cmd = CONCAT('echo "test" >> /test/mysqltrigger.txt');
SET result = sys_exec(cmd);
-- // this line also work OK
INSERT INTO test (column1,column2) VALUES (@var,'test') ;
END;
Please, hint a solution if available,

Hi All,
I am using:
MySQL 5.1.73 on Red Hat Enterprise Linux Server release 6.8 (Santiago)
When trying to install, I get following error : ERROR 1124 (HY000): No paths allowed for shared library
Has anyone faced the same issue and managed to find a fix.
Any input would be appreciated.
Thanks,

Hello,
This plugin seems promising BUT only for 32-bits systems.
Please, let us help you if you need and
Moreover, it would be nice to be able to double check the source.
Many thanks for your great work ;)
Hi guys.
Appreciate a ton of awesome works done. This is an awesome tool.
When I tried to install this on a CentOS server that have installed MariaDB 10.2+, it failed and I have figured out the reasons.
Finally this is fixed in the devel branch of mysqlclient but not yet released, it was due to a recent change in MariaDB 10.2.8 that does change the location of the server headers to a /server folder to avoid colliding headers from server and client.
from https://stackoverflow.com/questions/45905026/error-installing-mysqlclient-with-mariadb-10-2
This needs to be fixed on the side of codes. Hope my founding is helpful for any contributor.
Will we have an update for this change?
/usr/bin/ld: /tmp/ccFZ9hBW.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
Here is a patch to the above issues with sys_evail()
I found the issues while checking the function with valgrind.

Hey, thanks for your great work
I used sys_exec to execute php code from mysql trigger
What OS user (root or mysql user) that used by this function ? because, sometimes it gives me an error Permission denied when I try to create file on some root folder but it doesn't give me error when create on /tmp/ folder
Hello there,
I have gone through all the things and the installtion was successfull on my other server but when it came for my prodution server it through the error

Any idea where issue could be coming from?
One feedback from different forum suggested change of libraries at mysql end? Looking into by trying to install/use udf shipped with mysql?
Looking into it.
Any other suggestion if you have experienced the same will be of help.
Thanks

Hello!
I've compiled the lib via
gcc -DMYSQL_DYNAMIC_PLUGIN -fPIC -Wall -I/usr/include/mysql -I. -shared lib_mysqludf_sys.c -o lib_mysqludf_sys.so
I've then sym-linked it in the mysql's plugins folder. Eventually I've created the two functions:
CREATE FUNCTION sys_exec RETURNS int SONAME 'lib_mysqludf_sys.so';
CREATE FUNCTION sys_eval RETURNS int SONAME 'lib_mysqludf_sys.so';
So far so good. I've created a simple PHP script which prints out the time of execution and exits code status 0:
<?php
$date = date('Y-m-d h:i:s');
$text = sprintf("[%s] Execution\n", $date);
echo $text;
exit(0);
php is in /usr/bin/php
mysql> select sys_exec('/usr/bin/php /tmp/test/test.php');
+---------------------------------------------+
| sys_exec('/usr/bin/php /tmp/test/test.php') |
+---------------------------------------------+
| 0 |
+---------------------------------------------+
1 row in set (0.07 sec)
(fine). If I change the exit code to 1 (exit(1);
), this is the output:
mysql> select sys_exec('/usr/bin/php /tmp/test/test.php');
+---------------------------------------------+
| sys_exec('/usr/bin/php /tmp/test/test.php') |
+---------------------------------------------+
| 256 |
+---------------------------------------------+
1 row in set (0.07 sec)
256? But let's return to exit 0 and try out sys_exec:
mysql> select sys_eval('/usr/bin/php /tmp/test/test.php');
+---------------------------------------------+
| sys_eval('/usr/bin/php /tmp/test/test.php') |
+---------------------------------------------+
| NULL |
+---------------------------------------------+
1 row in set (0.07 sec)
Note: /tmp/test
has rwx permissions for all (ugo+rwx).
Let's try something easier:
mysql> select sys_eval('pwd');
+-----------------+
| sys_eval('pwd') |
+-----------------+
| NULL |
+-----------------+
1 row in set (0.02 sec)
Is my compiled library... failing?
Hi! Im looking forward in getting this set up for my raspberry project. I'm running raspbian and I opened mySQL using root and tried to create the function with
CREATE FUNCTION sys_eval RETURNS STRING SONAME 'lib_mysqludf_sys.so';
but it gives me this error:
Can't open shared library 'lib_mysqludf_sys.so' (errno: 0 /usr/lib/mysql/plugin/lib_mysqludf_sys.so: cannot open shared object file: No such file or directory)
Where is this library?
I did install libmysqlclient15-dev.
First off, thank you for writing this. I look forward to it working.
I'm getting a build error when trying to "make":
gcc -Wall -I/usr/include/mysql -I. -shared lib_mysqludf_sys.c -o /usr/lib/lib_mysqludf_sys.so /usr/bin/ld: /tmp/ccqmuRkb.o: relocation R_X86_64_32 against

/tmp/ccqmuRkb.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [install] Error 1`
I'm trying to build this on RHEL 6.3, with the Percona server (devel packages included). Any ideas?
I am running Ubuntu 16.04.5 LTS, MySQL 14.14 Distrib 5.7.22, for Linux (x86_64)
I have tried the install.sh script and I get the error:
ERROR: You need libmysqlclient development software installed
to be able to compile this UDF, on Debian/Ubuntu just run:
apt-get install libmysqlclient15-dev
But when I try to install that I get "Unable to locate package libmysqlclient15-dev"
When I try to install with out the "15" in the name I get a message saying I have the latest version:
"libmysqlclient-dev is already the newest version (5.7.22-1ubuntu14.04)"
Any thoughts on how to fix this issue?
Hi there, people!
I was wondering, if 'mysqludfsys' needs root's permission to be installed, why in the hell I would need this program to "become" a root through MySQL commands?
Would be easier whether we just command: $sudo su ?
Sudo command to install programs in owned server is not a trivial thing to be done during an invasion. So, if I have "sudo" permissions, I go to the system with it and not with mysqludfsys stuffs. Sorry!
Hi,
I try to use this plugin on a 5.5.42-MariaDB, Thus I compiled (gcc -DMYSQL_DYNAMIC_PLUGIN -fPIC -Wall -I/usr/include/mysql -shared lib_mysqludf_sys.c -o /usr/lib/mysql/plugin/lib_mysqludf_sys.so) the .so and placed it in the right folder then created the function like this:
CREATE FUNCTION sys_exec RETURNS int SONAME 'lib_mysqludf_sys.so';
CREATE FUNCTION sys_eval RETURNS string SONAME 'lib_mysqludf_sys.so';
No errors, but:
