In order to use a password to connect to MySQL as root, you will need to switch its authentication method from auth_socket to mysql_native_password. To do this, open up the MySQL prompt from your terminal:
Note that, at this point, you do not need to run the FLUSH PRIVILEGES command again. This command is only needed when you modify the grant tables using statements like INSERT, UPDATE, or DELETE. Because you created a new user, instead of modifying an existing one, FLUSH PRIVILEGES is unnecessary here.
Looking At MySQL Again
For an additional check, you can try connecting to the database using the mysqladmin tool, which is a client that lets you run administrative commands. For example, this command says to connect to MySQL as root (-u root), prompt for a password (-p), and return the version.

... against unexpected changes: like most disk-backed storage systems, MySQLis as reliable as the disks and filesystems its data lives on. MySQL providesno additional functionality in terms of mirroring or hardware failure tolerance(such as Oracle ASM).However this is a limitation shared with many, many other systems.
I ran an sql via the mysql command prompt, but it was taking too long so I decided to stop it. I closed the window, but I could see in Task Manager that mysqld.exe was still using 50% of my CPU. I therefore ended that process via the task manager. But now I don't know how to reconnect to MySQL. If I try to start a mysql command prompt again, I'm told that it can't connnect. I also tried "net start MySQL" but it says that the service name is invalid. Last time, I ended up restarting my computer.
The socket file can be in a non-standard path. In this case, the socket option is probably written in the my.cnf file. Check that its value is identical in the [mysqld] and [client] sections; if not, the client will look for a socket in a wrong place.
or can connect to a particular database, but not another, for examplemysql -u name db1 works but not mysql -u name db2, you have not been granted permission for the particular database. See the GRANT article.
It's possible that option files or environment variables may be providing incorrect connection parameters. Check the values provided in any option files read by the client you are using (see mysqld Configuration Files and Groups and the documentation for the particular client you're using - see Clients and Utilities).
Then try accessing the MySQL prompt again. If you still receive the socket error, double check the location where your MySQL installation is looking for the socket file. This information can be found in the mysqld.cnf file:
When I ran you php script (many thanks for that!!) I get this message for every ALTER/MODIFY command:PHP Notice: Undefined variable: res in /usr/home/bbking/mysql-convert-latin1-to-utf8.php on line 201
Full-Text Search in MySQL server lets users run full-text queries against character-based data in MySQL tables. You must create a full-text index on the table before you run full-text queries on a table. The full-text index can include one or more character-based columns in the table.
Natural language full-text search interprets the search string as a free text (natural human language) and no special operators are required. Full-text searches are natural language searches if the IN NATURAL LANGUAGE MODE modifier (see the following syntax) is given or not. MATCH() function searches a string against a text collection (A set of one or more columns included in a FULLTEXT index.). For each row in the table, MATCH() returns a relevance value; that is, a similarity measure between the search string (given as the argument to AGAINST() function) and the text in that row in the columns named in the MATCH() list.
So what we are looking at is basically a spreadsheet and the spreadsheet is basically a huge table a large table, right? And, and what what we are going to do is basically design a table for a ecommerce website, an e commerce website is basically like an amazing zone, or E Bay, or whatever, like online business, like online e commerce website, like Alibaba, or whatever, right? Let's say like, you have only one table in this database, right? And you start, as the orders come in, through this website, you start putting data into this table, right? You have, you know, let's look at some of the things that you will record in this table, right, you obviously need like a count of your orders.
Once I take out the customer information, I have the Orders table, the initial table, I'm calling Orders table looking like this now, right? And you can see that I've got like customer ID column over here.
And if you are wanting to delete a particular row, again, similar to the update, you can use a where clause to actually like narrow down the data that you want to delete this particular statement, which is delete from a table name, and then where column name equals or the column value.
So basically, you have the similar query where you're joining T one and T two, a left join first on this, there's one column that we have, and then you have another query, again, joining T one and T two on this, just one column, but then we are doing a union of these two, and that's going to return the data from both the tables, we have one, two, these two are matching, then for two, there is no matching value.
But if I try to update this value from two to three, another update, that is basically going to wait on the Select, basically this transaction that is running right now because the Select again, select is just a read, it is just reading the data.
So if you run the same query, again, is ready, you can see that this index has been created on products three table, which is maintained internally by my SQL, for just the purpose of clustering this table, actually.
You will need to remove any " you have from your MySQL root password. Once this has been done, the error should be resolved. Never put any " into your MySQL root password or else this problem will occur again.
Hello! I'm looking to build a distinct list of applications from Macs within a certain building. I've modified a sample query to give me a list of all applications on all computers, but I don't want a report of computer names with all applications installed on them. I want a distinct list of applications.
If you are looking to migrate large databases with database sizes more than 1 TBs, you may want to consider using community tools like mydumper/myloader which supports parallel export and import. Learn how to migrate large MySQL databases.
Create an empty database on the target Azure Database for MySQL server where you want to migrate the data. Use a tool such as MySQL Workbench or mysql.exe to create the database. The database can have the same name as the database that is contained the dumped data or you can create a database with a different name.
I am currently using MySQL 5.1 version (all my tables are innodb, most tables on latin and some on utf8).. if I want to upgrade to mysql 8.0, will it be an easy upgrade? or is it better I upgrade to mysql 5.7 first and then 8.0?
There are several ways to add data into the database: (a) manually issue the INSERT commands; (b) run the INSERT commands from a script; or (c) load raw data from a file using LOAD DATA or via mysqlimport utility.
Restore: The utility mysqldump produces a SQL script (consisting of CREATE TABLE and INSERT commands to re-create the tables and loading their data). You can restore from the backup by running the script either:
MySQL provides a command-line utility, mysqldump, that can be utilized to create backups by exporting databases as raw SQL files. You can run the command manually every day or install an automation script, like automysql backup, that will do it for you on a daily basis.
Be sure to save this content into a separate text editor; you will need it later in the article when you reiterate the steps of deleting a pod and re-creating your MySQL data. Also, note that by default, MySQL saves the data into a path called /var/lib/mysql. We'll use this path as the reference for our PersistentVolumeClaim when we redeploy the application later.
We used a DeploymentConfig with ReplicaSet, so a new instance spins up to replace the one that we've just deleted. Wait a short time, then execute the OpenShift oc get pods command. You should see that a new pod is running. Connect to the new pod with the oc rsh command. For my example, the command is oc rsh pod/mysql pnpq4. When you log in to MySQL, check for the created database table. Unfortunately, the table is empty, as shown in Figure 18.
Next, introduce a new line after terminationMessagePolicy. Enter volumeMounts: and add a mountPath with the value set to /var/lib/mysql. Enter mysql-volume, which is the volume name that you created in the previous step.
Use the rsh pod/POD_NAME command again to ssh into the pod, then enter printenv grep MYSQL. As shown in Figure 25, you should see that the environment variables were successfully picked up from the secret.
You might find that you are looking for an account number, but you only have 5 of the 6 digits. The example above, would retrieve potentially 10 records back (where the missing value could equal anything from 0 to 9). For example, it could return suppliers whose account numbers are:
Redis provides an alternative caching backend, taking that work off the database, which is vital for scaling to a larger number of logged-in users. It also provides a number of other nice features for developers looking to use it to manage queues, or do custom caching of their own. 2ff7e9595c
