php - MySql PDO access denied when passing pdo object to another class -

-

i have 2 linux vms below configuration:

vm 1:
os: redhat enterprise linux 5.4
apache: 2.2.23
php: 5.5.3
mysql: 5.5.28
php config: './configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--prefix=/usr/local/apache2/php' '--with-config-file-path=/usr/local/apache2/php' '--disable-cgi' '--with-zlib' '--with-gettext' '--with-gdbm' '--with-sqlite3' '--enable-sqlite-utf8' '--with-mysql=/usr/local/mysql/' '--with-pdo-mysql=mysqlnd' '--enable-mbstring' '--enable-calendar' '--with-curl=/usr/lib' '--with-gd' '--with-jpeg-dir=/usr/lib/libjpeg.so' '--with-png-dir=/usr/lib/libpng.so' '--enable-soap' '--enable-bcmath'

vm 2:
os: redhat enterprise linux 6.4
apache: 2.4.6
php: 5.3.27
mysql: 5.6.13
php config: './configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--prefix=/usr/local/apache2/php' '--with-config-file-path=/usr/local/apache2/php' '--disable-cgi' '--with-zlib' '--with-gettext' '--with-gdbm' '--with-sqlite3' '--enable-sqlite-utf8' '--with-mysql=mysqlnd' '--with-pdo-mysql=mysqlnd' '--enable-mbstring' '--enable-calendar' '--with-curl=/usr/lib' '--with-gd' '--with-jpeg-dir=/usr/lib/libjpeg.so' '--with-png-dir=/usr/lib/libpng.so' '--enable-soap' '--enable-bcmath' '--with-mysqli=mysqlnd' '--with-pdo-sqlite' '--with-pear' '--enable-ftp' '--with-openssl'

i have php class connects mysql database using pdo using following code:

    try {                     $this->maindb = new pdo(pdo_mysql_host_dbname, pdo_mysql_user, pdo_mysql_password, array(pdo::attr_persistent => true));         $this->maindb->setattribute(pdo::attr_errmode, pdo::errmode_exception);                 } catch (pdoexception $e) {         die('error connecting database: ' . $e->getmessage());     }

this part works fine, , data gets inserted database expected.

strangely towards end of class, when create object of class , pass $this->maindb object 1 of methods write more data, fails 'sqlstate[28000]: invalid authorization specification: 1045 access denied user 'team'@'localhost' (using password: yes)' error.

my problem is, same code works fine on vm1, , fails on vm2 described. have tried these options:

  • with both persistent , non-persistent connections.
  • used mysql root user privileges.

i have no idea might causing problem. please me sort out.

note: prefer solution doesn't involve downgrading packages.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
