Mysqlshow: Unknown database 'nonexistingDB' 40.4k 59 194 332 Add a comment 13 Answers Sorted by: 604 See here mysql -u USERNAME -pPASSWORD -h HOSTNAMEORIP DATABASENAME The options above means: -u: username -p: password (no space between -p and the password text) -h: host last one is name of the database that you wanted to connect. Let’s also check a non-existing database and see the result: $ mysqlshow -user user -host localhost -socket /tmp/ nonexistingDB The exit status of the command execution was 0. The output of running mysqlshow listed the tables in the database. Finally, we specified the students database. The –socket option’s the socket file to connect to the server. The –host option’s for specifying the host on which the MySQL server is running. We specified the user to connect to the MySQL server using the –user option. Disclamer: I am not associated with this blog.Let’s inspect it with an example: $ mysqlshow -user user -host localhost -socket /tmp/ students on *.* to could simply run REVOKE ALL ON *.* TO How does one identify all permissions like this? Do I have to look over every user? P.S: You might need to replace 'localhost' with your db hostname.ġ) How does one drop this permission? I assume if I run: REVOKE SELECT, INSERT. (or restart MySQL - if that's an option - often it's not). REVOKE SHOW DATABASES ON *.* FROM reload all the privileges using the command: FLUSH PRIVILEGES If SHOW DATABASES is enabled, revoke that permission. Note that any global privilege is a privilege for the database. ![]() Accounts that do not have this privilege see only databases for which they have some privileges, and cannot use the statement at all if the server was started with the -skip-show-database option. I am going to show you three different methods to get the lists using GUI. The SHOW DATABASES privilege enables the account to see database names by issuing the SHOW DATABASE statement. You might find it useful to list all the views/tables in a particular database. You should be able to view the users' grants using the command: SHOW GRANTS FOR the MySQL manual: But maybe it's best to just remove all privileges and build them back up from scratch.Ģ) How does one identify all permissions like this? Do I have to look over every user? on *.* to will remove permissions like GRANT ALL ON bobsdb.* TO I don't want to happen. ON *.* TO How does one drop this permission? I assume if I run: REVOKE SELECT, INSERT. Once you are logged into MySQL, type the following command to list all databases on the server: show databases 5. your username and password (optional if you username is root) grant you the needed access to the databases. If you request show databases without this, cmd will only show you default databases. LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW,ĬREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE MySQL Cluster is a real-time open source transactional database designed for fast, always-on access to data under high throughput conditions. Type the following command at the shell prompt, replacing USERNAME with your actual MySQL username: mysql -u USERNAME -p 3. You can even go as far as auto-compressing the output using gzip (if your DB is very big): mysqldump -u uname -p dbname gzip > . First, you have to log in using your username and password before you issue show databases command on cmd. PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, Not sure what I am missing here.Įdit: I ran SHOW GRANTS FOR and see: GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, ![]() I create a new database sometest, switch to bob's account and see that bob has access to sometest. Type the following command at the shell prompt, replacing USERNAME with your actual MySQL username: mysql -u USERNAME -p 3. Nothing jumps out like GRANT, ALL or SUPER. Assuming you have a database setup and running on a Linux server, here is how you can show databases in MySQL from the command line: 1. I run the following to see which privileges bob has: mysql -e "select * from information_er_privileges " | grep def SELECT def INSERT def UPDATE def DELETE def CREATE def FILE def CREATE USER NO The mysqlshow client can be used to quickly see which databases exist, their tables, or a tables columns or indexes. I'm trying to revoke privileges but I'm not sure how to go about it.įor example: I have a user bob who has access to every database on my server. I have a few users on my server who have access to every MySQL database. ![]()
