Today, we’ve seen the causes for the error and how our Support Engineers fix it.These instructions apply to Confluence 7.3 and later. “ Stopping mysql database server: mysqld failed!” is an error that occurs mainly due to wrong MySQL user password. After changing the password, we do a MySQL restart again using: /etc/init.d/mysql restart

Here, “mypassword” is the new password set. > SET PASSWORD FOR = PASSWORD('mypassword')

In order to fix the mismatch, our Support Engineers do the following commands from the Mysql prompt of the server. To view the current password for this user, we check the file / etc / mysql / debian. Now, if there is no problem with the root mysql user, we need to check the password for MySQL user “debian-sys-maint”. Fix mysql password for “debian-sys-maint” This ensures MySQL connectivity on the server.ģ. If there is problem with the root user password, we reset the password. For this, we use : mysql -p -u root password 'mypassword' Secondly, we check and confirm that we can connect to the MySQL server using root password. So we avoid doing this in normal situations. But, this often causes the loss of data, particularly if an actual write happens in the database. We can simply stop the mysqld process by using the “Kill” command. Here, we note down the process id of the working mysqld process. Mysql 2082 0.6 10.7 752544 111188 ?

It also stores the user’s details in the “users” table in the database too.īut, when we do actions like copying databases to another server, upgrade the MySQL installation, etc., there are chances that these passwords may differ. In Debian servers, there is a special MySQL user called “ debian-sys-maint“.ĭuring the installation, MySQL generates a random password for “ debian-sys-maint” and stores its credentials inside the file /etc/mysql/debian.cnf. But, server did not accept this password. Since, there was a part that stated “ using password: YES“, it means that the password was correct. Here, it showed an additional error that there was access restriction for the MySQL user. usr/bin/mysqladmin: connect to server at 'localhost' failedĮrror: 'Access denied for user (using password: YES)' Starting MySQL database server: mysqld already running. Stopping MySQL database server: mysqld failed!

The typical error message was : # /etc/init.d/mysql restart Recently, in a Debian server, mysqld failed to restart after copying the databases. And, the changes will be effective, only if the restart is successful.

MySQL server often needs restart in various situations like data migration, version upgrade, etc. What causes “Stopping mysql database server: mysqld failed!” error? Today, let’s discuss on the top causes for this error and how we fix it. And, sometimes this restart can fail with errors like “Stopping mysql database server: mysqld failed!”Īt Bobcares, we help server owners to fix MySQL server errors as part of our Support Services for Web Hosts. They need continuous updates to avoid performance problems.Īfter any configuration change, MySQL server needs a restart to bring the changes into effect. Database servers functions as the backbone for websites.
