Joe Brockmeier commented on CLOUDSTACK-400:
-------------------------------------------
Added in commit 2bd877616bd7f17c592385e60e01459dd27097bd to master, but I
haven't documented the other encryption types yet.
> Document procedure to update CloudStack MySQL account password

> Key: CLOUDSTACK-400
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-400
> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Doc
> Affects Versions: 4.0.0
> Reporter: Kirk Kosinski
> Assignee: Joe Brockmeier
> Priority: Minor
> Labels: adminguide, database, mysql

> An administrator may occasionally want to change the password for the MySQL
> account used by CloudStack. When password encryption is used as recommended,
> this procedure is complicated and should be documented. I wrote the following
> procedure for the "file" encryption type and QA verified it. The procedure
> for "web" encryption is likely similar. It may also be useful to include a
> procedure for no encryption.
> 1. Stop CloudStack and (if applicable) the usage engine.
> service cloud-management stop
> service cloud-usage stop
> 2. Update the password for the CloudStack user on the MySQL server. Open a
> MySQL prompt:
> mysql -u root -p
> Run the following:
> update mysql.user set password=PASSWORD("newpassword123") where User='cloud';
> flush privileges;
> And exit the prompt:
> quit
> 3. Encrypt the password and copy the resulting ciphertext:
> java -classpath /usr/share/java/cloud-jasypt-1.8.jar
> org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI encrypt.sh
> input="newpassword123" password="`cat /etc/cloud/management/key`"
> verbose=false
> Note: If using db.cloud.encryption.type=web, use:
> password="management_server_secret_key"
> 4. Update /etc/cloud/management/db.properties with the new ciphertext:
> db.cloud.password=ENC(encrypted_password_from_above)
> db.usage.password=ENC(encrypted_password_from_above)
> 5. Start CloudStack and (if applicable) the usage engine.
> service cloud-management start
> service cloud-usage start
