'''Steps''':
==For Mysql Database==


1) For Mysql:
1. Stop the mysql service. [Run as Zimbra]


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


b) Run as ROOT vi /opt/zimbra/bin/mysql.server
2. Modify the /opt/zimbra/bin/mysql.server to start the mysql with skipping the grant tables. [Run as ROOT]


c) Modify the following:
  # vi /opt/zimbra/bin/mysql.server
Modify the following:
       --defaults-file=${mysql_mycnf} \
       --defaults-file=${mysql_mycnf} \
       --external-locking \
       --external-locking \
       --ledir=${mysql_directory}/libexec < /dev/null > /dev/null 2>&1 &

The Problem

Due to wrong passwords in the database of mysql/logmysql is not able to connect to the database with the existing password. We need to change the passwords manually.

The Error

The error might looks like this. 

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

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

For Mysql Database

1. Stop the mysql service. [Run as Zimbra] 

 $ mysql.server stop

2. Modify the /opt/zimbra/bin/mysql.server to start the mysql with skipping the grant tables. [Run as ROOT] 

 # vi /opt/zimbra/bin/mysql.server

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.

3. Start the mysql service. [Run as Zimbra] 

 $ mysql.server start

4. Connect to the database and change the passwords. 

   # mysql
   Welcome to the MySQL monitor.  Commands end with ; or \g.
   Your MySQL connection id is 6883
   Server version: 5.0.45-log Source distribution
   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 in the localconfig. Run following command to check those passwords. 

 zmlocalconfig -s | grep mysql_root_password
 zmlocalconfig -s | grep zimbra_mysql_password

Flush the privileges and exit. 

 mysql> FLUSH PRIVILEGES;
 mysql> exit

5. Go back to the file remove the --skip-grant-tables from /opt/zimbra/bin/mysql.server and save and exit the file. You will need to do it as root.

6. Stop and start the mysql service. [Run as zimbra] 

 $ mysql.server stop
 $ mysql.server start

7. Now you should be able to connect to the mysql. 

 $ mysql zimbra

For logger database

1. Stop the logger mysql service. [Run as Zimbra] 

 $ logmysql.server stop

2. Modify the /opt/zimbra/bin/logmysql.server to start the logmysql with skipping the grant tables. [Run as ROOT] 

 # vi /opt/zimbra/bin/logmysql.server

Modify the following: 

     --defaults-file=${logger_mysql_mycnf} \
     --external-locking \
     --ledir=${logger_mysql_directory}/libexec &

   TO

     --defaults-file=${logger_mysql_mycnf} \
     --external-locking \
     --ledir=${logger_mysql_directory}/libexec --skip-grant-tables &

Save and Exit the file.

3. Start the logmysql service. [Run as Zimbra] 

 $ logmysql.server start

4. Connect to the database and change the passwords. 

   # logmysql
   Welcome to the MySQL monitor.  Commands end with ; or \g.
   Your MySQL connection id is 6883
   Server version: 5.0.45-log Source distribution
   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 in the localconfig. Run following command to check those passwords. 

 zmlocalconfig -s | grep mysql_logger_root_password
 zmlocalconfig -s | grep zimbra_logger_mysql_password

Flush the privileges and exit. 

  mysql> FLUSH PRIVILEGES;
  mysql> exit

5. Go back to the file remove the --skip-grant-tables from /opt/zimbra/bin/logmysql.server and save and exit the file. You will need to do it as root.

6. Stop and start the mysql service. [Run as zimbra]
