How to Fix MySQL Error - ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG

MySQL is a popular open-source relational database management system used by many websites and applications. However, like any software, it can encounter errors that need to be resolved. One such error is the ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG error. In this article, we will explore what causes this error and how to fix it.

Understanding the ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG Error

The ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG error occurs when attempting to set up replication between a master and a slave MySQL server. This error message indicates that the password provided for the replication user is too long.

When setting up replication, MySQL requires a replication user on the master server and a corresponding user on the slave server. The password for these users must match. However, there is a limitation on the maximum length of the password, which is 32 characters by default.

If the password provided for the replication user exceeds this limit, MySQL throws the ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG error.

Fixing the ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG Error

To fix the ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG error, you need to ensure that the password for the replication user is within the allowed length limit. Here are the steps to follow:

Step 1: Update the Master Server Password

First, you need to update the password for the replication user on the master server. Make sure the new password is within the allowed length limit of 32 characters.

You can update the password using the following SQL command:

SET PASSWORD FOR 'replication_user'@'master_server' = PASSWORD('new_password');

Replace 'replication_user' with the actual username of the replication user and 'master_server' with the hostname or IP address of the master server.

Step 2: Update the Slave Server Password

Next, you need to update the password for the replication user on the slave server to match the new password set on the master server.

Use the following SQL command to update the password:

SET PASSWORD FOR 'replication_user'@'slave_server' = PASSWORD('new_password');

Replace 'replication_user' with the actual username of the replication user and 'slave_server' with the hostname or IP address of the slave server.

Step 3: Restart the MySQL Service

After updating the passwords on both the master and slave servers, you need to restart the MySQL service on both servers for the changes to take effect.

You can restart the MySQL service using the following command:

sudo service mysql restart

Make sure to execute this command on both the master and slave servers.

Summary

The ER_SYNC_SLAVE_REPORT_PASSWORD_TOO_LONG error in MySQL occurs when the password for the replication user exceeds the allowed length limit. To fix this error, you need to update the passwords on both the master and slave servers to ensure they are within the limit. After updating the passwords, restart the MySQL service on both servers.
