The replication user for Mysql does not have enough privileges in the latest version of Mysql 5.7-31 and MySql 8.0-xxx  which is included in the latest platform

(Layer7_API_PlatformUpdate_64bit_v9.X-CentOS-2020-09-23.L7P ) .

After upgrading MySQL to 5.7.31 the script to setup the slave replication or restart the replication fails on copying the database to the slave with the following error.

Do you want to clone a database from xx.xx.xx.xx (yes or no)? [no] yes
Enter name of database to clone: [ssg]

  About to drop the ssg database on localhost
  and copy from xx.xx.xx.xx

Are you sure you want to do this? [N] yes
mysql: [Warning] Using a password on the command line interface can be insecure.
mysqldump: [Warning] Using a password on the command line interface can be insecure.
mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces


Release : 9.4 10.x

Component : API GATEWAY


The user used for the replication is created with the script "" which does not include the PROCESS privilege as it was not required before MySQL 5.7.31.

The workaround  is to grant the replication users the required PROCESS privilege manual .

To do this go into a command shell and run mysql.

in MySQL do the following :

mysql> use mysql;

list all users to identify your replication users.

mysql> SELECT user,host FROM mysql. user;

| user          | host                            |
| repluser      | xx.xx.xx.xx                  |
| repluser      | yy.yy.yy.yy                   |
|    |

add the replication users the PROCESS privileges by default there are two users called 'repluser' assign both the process privileges .

mysql > GRANT PROCESS ON *.* TO 'repluser'@'replhostip/name' IDENTIFIED BY 'replpass';    

or for MySQL 8

mysql > GRANT PROCESS ON *.* TO 'repluser'@'replhostip/name'

flush privileges;

After this rerun the script to restart the replication.
