I am trying to build mysql-5.0.33 client library with SSL support. For which I am using
./configure --prefix=<some dir> --exec-prefix=<some dir> --with-openssl=<path to openssl dir> --without-server`
to configure and then make
and make install
Version of OpenSSL linked to is 1.0.0a. There is no problem or error in above process.
Now I have program as follows
#include <mysql.h>
#include <stdio.h>
int main() {
MYSQL *conn;
MYSQL_RES *res;
MYSQL_ROW row;
char *server = "192.168.1.62";
char *user = "testssl";
char *password = "testssl"; /* set me first */
char *database = "mysql";
int port = 3321;
conn = mysql_init(NULL);
mysql_ssl_set(conn, "client-key.pem", "client-cert.pem", "ca-cert.pem", NULL, "DHE-RSA-AES256-SHA");
mysql_options(conn, MYSQL_OPT_CONNECT_TIMEOUT, "30");
/* Connect to database */
if (!mysql_real_connect(conn, server,
user, password, database, port, NULL, 0)) {
fprintf(stderr, "Real connect: %d: %s\n", mysql_errno(conn), mysql_error(conn));
return 1;
}
printf("SSL cipher used: %s \n", mysql_get_ssl_cipher(conn));
/* send SQL query */
if (mysql_query(conn, "show tables;")) {
fprintf(stderr, "\nQuery: %s\n", mysql_error(conn));
return 1;
}
res = mysql_use_result(conn);
/* output table name */
printf("Results:\n");
while ((row = mysql_fetch_row(res)) != NULL)
printf("%s \n", row[0]);
/* close connection */
mysql_free_result(res);
mysql_close(conn);
return 0;
}
This program is build as follows :
gcc -o mysql-ssl-test -I <some dir>/include/mysql/ mysql-ssl-test.c -L <some dir>/lib/mysql/ -lmysqlclient -lpthread -lz -lm -lrt -lssl -lcrypto -ldl`
The mysql server (192.168.1.62) which i am connecting has ssl enabled and the User testssl can connect over ssl only (GRANT ... REQUIRE SSL
). I have no problem connecting to the server using mysql command line or other mysql client line like Sqlyog.
Now i am getting error Real connect: 2026: SSL connection error
, when i trying to run the program with this command LD_LIBRARY_PATH=<some dir>/lib/mysql/ ./mysql-ssl-test
but it runs fine when tring to run with this command ./mysql-ssl-test
(Here it trys to link with system libmysqlclient which is v5.5.25 and OpenSSL 1.0.0-fips)
Interestingly if i replace the line
mysql_ssl_set(conn, "client-key.pem", "client-cert.pem", "ca-cert.pem", NULL, "DHE-RSA-AES256-SHA");`
with
mysql_ssl_set(conn, "client-key.pem", "client-cert.pem", "ca-cert.pem", NULL, NULL);`
it runs fine even with LD_LIBRARY_PATH=<some dir>/lib/mysql/ ./mysql-ssl-test
.
Is this a bug of mysql 5.0.33 or OpenSSL 1.0.0a that i have came across (googling for such bug was of no help) or I am doing some blunder while building libmysqlclient.
Fixed : It was some kind of bug in MySQL 5.0.33. Fixed by upgrading to 5.0.86.
