Issues with mysql and logmysql passwords

Issue:

Due to wrong passwords in the database mysql/logmysql is not able to connect to the database with the existing password.

We need to change the passwords manually.

Error:

1. logmysql

ERROR 1044: Access denied for user 'zimbra'@'localhost' to database 'zimbra_logger'

1. mysql

ERROR 1044: Access denied for user 'zimbra'@'localhost' to database 'zimbra'

Steps:

   1) For Mysql:

   a) Stop the mysql service. [Run as Zimbra: mysql.server stop]

   b) Run as ROOT vi /opt/zimbra/bin/mysql.server

   c) Modify the following:

     --defaults-file=${mysql_mycnf} \
     --external-locking \
     --ledir=${mysql_directory}/libexec < /dev/null > /dev/null 2>&1 &
   
   TO

     --defaults-file=${mysql_mycnf} \
     --external-locking \
     --ledir=${mysql_directory}/libexec < /dev/null > /dev/null 2>&1 --skip-grant-tables &

   Save and Exit the file.

   d) Start the mysql service. [Run as Zimbra: mysql.server start]

   e) Connect to the database.

   # mysql

   Welcome to the MySQL monitor.  Commands end with ; or \g.
   Your MySQL connection id is 6883

   Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

   mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';      ----> Root user.

   mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='zimbra';    ----> Zimbra user.

   Make sure the password you specify is should be same as  

   zmlocalconfig -s | grep mysql_root_password and zmlocalconfig -s | grep zimbra_mysql_password. 

   mysql> FLUSH PRIVILEGES;

   mysql> exit

   f) Go back to the file remove the --skip-grant-tables and save and exit the file.

   g) Stop and start the mysql service. [mysql.server stop and start]

   h) Now try to connect without the --skip-grant-tables option and check.
