To add a simple index to a database, login to /phpMyAdmin with your da_admin account ( /usr/local/directadmin/conf/nf), and go to the " mysql" database. Where, I believe the biggest gain was mysql.db:db. To optimize things, one can added 3 new index files on the related tables: The short of it is that DA was looking at a few rows that were not specifically indexes, thus the lookup would have been done in a linear fashion (I believe), hence very slow response time, as this server had 45,000 database accounts (yes this is a lot, but there is no limit). We had a report of slow response time for deleting database, where DA does some fancy queries to figure out if a User is on mysql databases or not, so it would only delete the User if it's only on the one being deleted. # MariaDb 10.4: Deleting Databases is slow / causes timeoutĪs of version 10.4, MariaDB has replaced the er table with mysql.globa_priv table, and er becomes a view:įor the most part, this really shouldn't matter, as DA would be using the mysql_use_new_user_methods=1 (for ALTER USER, etc, instead of direct er control). Note: DirectAdmin 1.56.0 and up will use -force by default, so you'd only need to make this edit for older versions. Where the -force option simply skips those DNS checks.ĭirectAdmin already makes sure that localhost exists in the /etc/hosts, so we're not concerned about these checks. Login to /phpMyAdmin with the da_admin user/pass found in /usr/local/directadmin/conf/nf
To do this, we need to login to /phpMyAdmin. The solution is to simply add the username account onto username_db. There is no username on username_db # Solution There is no username dbuser on usernamedb If you're seeing a total count of -1 on a given database, this would mean that: When DA counts the Users in mysql, it subtracts 1 from this count to show the total number in the "Number of Users" column.ĭA User Login: DB Name: username_ # Issue So if there is 1 username_dbuser on username_db, there is also username on username_db.
However, DA does not show the fact that the DA system User account (that User's DA login name) is also able to access this database (as it's highly discouraged to use it in scripts, etc.) When you click the DB, you can see these accounts. open in new window # MySQL: Number of Users shows -1, or one less than it shouldįor a User, the "MySQL Management" page listing the databases has a column called "Number of Users" which represents the number of MySQL accounts set up to use it. It is safe to delete this file, but only if MariaDB is not running: Do not run this if you need to restore your backups to get non-corrupted data: Run the following, but only if your data itself is still valid.
It's also recommended to have a copy of the MySQL data directory, so you can copy it back if things go south.ĬustomBuild can make the plain-text sql files for you. Before anything else, ensure you have full.It will essentially dump all databases to sql files, drop all databases, stop mysqld, delete the ib* data files, and restart mysqld and restore the sql files. If you want to change to use innodb_file_per_table, then you'd need to use this guide. On most operating systems innodb_file_per_table is set to “on” by default. Changing it after databases already exist could break things and force you to use this guide.
CENTOS MYSQL DELETE USER INSTALL
Note, that we recommend using the innodb_file_per_table in the section of your my.cnf from install time. This is never really a good position to be in, but there are ways of rebuilding these files into a clean slate. proc/sys/fs/aio-max-nr # I have a corrupted ibdata1 and related innodb files, I need to rebuild them. pass1 will be the root mysql password, and pass2 will be the da_admin MySQL password.Īnother reported solution is to increase your kernel setting: Where pass1 and pass2 can be set to any passwords you want.
