Also sudo does not do anything to help this problem.Beginners may face problems accessing MySql by the root.For example: $cfg = 'type your password here' To be able to reset the root rights, you should enter the following commands:Mysql> GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY ' your current password ' WITH GRANT Insert the host and passwordThis section will allow to insert the host's name and user account by default and set them up with the correct password, as allocated to them in the php.ini folder. Failed to connect to mysql at 127.0.0.1:3306 with user root access denied for user 'root''localhost'(using password:YES) Solution which worked for me: type in mysql command line client. As soon as you open you will be prompted with password-> mysql -u root -p -h 127.0.0.1 -P 3306.
Access Denied For User 'Root'@'Localhost' (Using No) When Trying To Connect How To Install MysqlAlso, this library by itself is written in python program and does not have any other external dependencies, which makes it easier to maintain.This tutorial explains how to install mysql-connector-python library. While there are few of these libraries available, the most popular and stable is mysql-connector-python library.The mysql-connector-python library uses APIs that are complaint with the Python Database API Specification v2.0 (PEP 249). Default password for mysqli_connect() (doesn't apply in safe mode):Note: It is generally a bad idea to store passwords in this file as any user with PHP access can view it Default user for mysql_connect() (doesn't apply in safe mode): Default host for mysql_connect() (doesn't apply in safe mode): From a Python program, you can connect to MySQL database to access the tables and manipulate your data.For this, you should use one of the Python MySQL Libraries. Using the IP address forces the connection to go over TCP instead of a unix socket (a special type of file that lets programs talk to each other).Where $cfg = '' is displayed, alter the command to $cfg = 'localhost/phpmyadmin/' Step 3: Concerning the server commands, change $cfg = 'localhost' to $cfg = 'Localhost' This can be easily configured using the following steps:My root user is enabled and I checked to see that the password is the same as my user login (and the same as it's always been) - but every time I try to run it, whether it be through Terminal or through Sequel Pro, I always get the same: Access denied for user 'root''localhost' (using password: YES)Step 2: Through phpMyAdmin/librarires, you should edit config.inc.php.See if setting the server name to127.0.0.1 instead of localhost does the trick.Verify Python MySQL Library is InstalledIn the following example, this server has Python 2.7.5 version installed. # rpm -ivh mysql-connector-python-2.1.3-1.el7.x86_64.rpm1:mysql-connector-python-2.1.3-1.el# 2. All you need is just this package. This does not have any other additional package dependencies. It is also available for Windows.You can download the mysql-connector-python from this download page.In the following example, I’m using wget command to directly download the RPM file to install it on CentOS 7.Next, use rpm command to install the mysql-connector-python library as shown below. 3 root root 78 Jun 9 08:14 mysql-rw-r-r-. # ls -l /usr/lib/python2.7/site-packages | grep -i mysqlDrwxr-xr-x. Verify whether we got the mysql_connector_python is available under that directory as shown below. # python> from distutils.sysconfig import get_python_libAs we see from the above output, on this particular system python libraries are installed under /usr/lib/python2.7/site-packages directory. Before you can use the get_python_lib function, you should also import that function as shown below. > print get_python_lib()NameError: name 'get_python_lib' is not definedNext, let us make sure the mysql library that we installed is valid, and we are able to import it without any issue. > print get_python_lib()Also, if you try to executing the get_python_lib without importing it, you’ll see the following error message. If you have any extra space in front of “print”, it will display the “IndentationError: unexpected indent” error message. This function will return a connection object, which we are storing in the “conn” variable. Connect to MySQL Database from Python ProgramNext, let us write a quick small sample python program that will connect to a specific MySQL database using an user name and password.In the following example, this python program will try to connect to a MySQL database called “thegeekstuff” that is running on the localhost (127.0.0.1), with the given username and password.Mysql.connector.connect is a mysql-python library function that will create this connection as shown below. > import mysql.connectorImportError: No module named mysql.connector4. # pythonIf you get the following error, then something is wrong with the Python MySQL library installation. From this point on-awards, you can start using any MySQL python library commands and get it going. Outlook 2011 for mac will not connect to exchange# python con-test.pyFile "/usr/lib/python2.7/site-packages/mysql/connector/_init_.py", line 179, in connectFile "/usr/lib/python2.7/site-packages/mysql/connector/connection.py", line 95, in _init_File "/usr/lib/python2.7/site-packages/mysql/connector/abstracts.py", line 719, in connectFile "/usr/lib/python2.7/site-packages/mysql/connector/connection.py", line 210, in _open_connectionFile "/usr/lib/python2.7/site-packages/mysql/connector/connection.py", line 144, in _do_authSelf._auth_switch_request(username, password)File "/usr/lib/python2.7/site-packages/mysql/connector/connection.py", line 177, in _auth_switch_requestMysql.connector.errors.ProgrammingError: 1045 (28000): Access denied for user (using password: YES)5. In the following example, it gives “Access denied” error message, which means that the given username and password combination is invalid. # python con-test.pyIf there is an error while making the connection, it will throw an error messages as shown below. # cat con-test.pyIf you are trying to connect to a MySQL database that is running on a different server, then change the ip-address in the host parameter accordingly.If you execute the above sample python program as shown below, if it doesn’t return any error message, then it means that the program was able to successfully make the connection to given MySQL database using the given username and password. Finally, we are using conn.close(), which will simply close the MySQL connection that was opened. conn = mysql.connector.connect – Connects to a specific MySQL datbase using the given db name, username, password and host. import mysql.connector – Imports the mysql connector python library. # cat employee.pyPrint("".format(id, name,dept,salary)) In this python script example, it will connect to “thegeekstuff” MySQL database, and retrieve data from employee table, and display it. query = (“SELECT … ) – Here we are definting our MySQL query. The cursor object will be stored in the “cur” variable. cur = conn.cursor() – Using the connection object that we just created, we are creating a new cursor to retrieve and manipulate our query. I.e id, name, dept and salary. Since this table has 4 columns, there are 4 variables defined inside the for loop. for (…) in cur – This command just loops through the cursor and gets all the values in the rows and stores them in the given parameter. Since the cursor is already tied to a specific connection, it knows exactly where to execute the SQL query and get the output. cur.execute(query) – Using the “cur” cursor variable that we created above, we are executing the given query.
