8.2 Installing SSL Certificates

Important

The self-signed certificates are generated by the MySQL Enterprise Monitor installation or upgrade process, and are set to expire after 365 days. In the unlikely event you are running a version of MySQL Enterprise Service Manager using the default certificates for more than a year, you must generate new certificates. If you do not generate new certificates, the SSL connection between MySQL Enterprise Service Manager and the repository fails. This section describes how to generate those certificates.

These instructions guide you through the process of installing SSL certificates for your MySQL Enterprise Monitor installation.

Checking the Keystore

All certificates and keys are stored in the Tomcat keystore. To check the certificates stored in the keystore, run the following command:

keytool -keystore $INSTALL_ROOT/apache-tomcat/conf/keystore -list -v

Generating Keystore, Key, and Certificate

For all certificate-related activities, it is recommended to use the MySQL Enterprise Monitor Configuration Utility. See Chapter 11, Configuration Utilities for more information.

To generate the certificate and add it to the default keystore, run the following command with the MySQL Enterprise Monitor Configuration Utility:

  config --renew

This regenerates the self-signed certificate. If the certificate is not self-signed, an error is displayed.

MySQL Enterprise Service Manager SSL Import

To install an SSL certificate for the MySQL Enterprise Service Manager, use the MySQL Enterprise Monitor Configuration Utility to import the certificate into the keystore.

To import your certificate, run the following command:

  config --import-certificate=/path/to/client.crt

To import an existing certificate and key, run the following command:

  config --import-certificate=/path/to/client.crt --import-key=/path/to/client.key

Restart the service manager. For more information about stopping and starting the service manager, see the instructions for Unix/macOS and Microsoft Windows.

SSL for the Repository

For information on SSL and MySQL Server, see Creating SSL and RSA Certificates and Keys.

MySQL Enterprise Monitor Agent

To configure SSL-related options for the Agent, the following values may be placed in $INSTALL_ROOT/etc/bootstrap.properties:

Table 8.1 Agent SSL Configuration Options

Parameter	Description
ssl-verify-hostnames	Values: True or False (default). SSL connection between service manager and agent. Verify that the hostname of the service manager that the agent is connected to matches what is in the SSL certificate.
ssl-allow-self-signed-certs	Values:True (default) or False. SSL connection between agent and MySQL instance. If set to true self-signed certificates are permitted. If set to false, self-signed certificates are not permitted.
ssl-ca-keystore-path	Values: String SSL connection between agent and MySQL instance. Path to keystore with CA cert(s), if ssl-allow-self-signed-certs is true. This path must be defined as a URL. For example: file:///Applications/mysql/enterprise/agent/etc/mykeystore
ssl-ca-keystore-password	Values: String SSL connection between agent and MySQL instance. Password for the CA keystore, if ssl-allow-self-signed-certs is true.

An example bootstrap.properties SSL certification section:

ssl-verify-hostname=false
ssl-allow-self-signed-certs=true
ssl-ca-keystore-path=file:///Applications/mysql/enterprise/agent/etc/mykeystore
ssl-ca-keystore-password=password123

To import a CA certificate in PEM format to a new keystore on the Agent, execute the following:

$INSTALL_ROOT/java/bin/keytool -import -file /path/to/ca/ca.pem -alias CA_ALIAS -keystore $INSTALL_ROOT/etc/cacerts

The tool responds with the certificate details. For example:

Enter keystore password:  (the keystore requires at least a 6 character password)
Re-enter new password:

Owner: CN=serverName.com, O=MySQL AB, ST=Uppsala, C=SE
Issuer: O=MySQL AB, L=Uppsala, ST=Uppsala, C=SE
Serial number: 100002
Valid from: Fri Jan 29 12:56:49 CET 2010 until: Wed Jan 28 12:56:49 CET 2015
Certificate fingerprints:
     MD5:  E5:FB:56:76:78:B1:0C:D7:B0:80:9F:65:06:3E:48:3E
     SHA1: 87:59:80:28:CE:15:EF:7E:F1:75:4B:76:77:5E:64:EA:B7:1D:D1:18

             84:F4:06:6E:8E:CF:C1:F6:1B:52
     Signature algorithm name: MD5withRSA
     Version: 1
Trust this certificate? [no]: (type yes + enter)
Certificate was added to keystore

You must edit the ssl-ca-* configuration values in bootstrap.properties accordingly, to use the path to the keystore and password.

Note

The connection between the agent and service manager is also an SSL connection.

LDAP SSL Configuration

SSL configuration for LDAP is configured at the MySQL Enterprise Service Manager Java VM level. That is, it is configured in the keystore of the Java VM bundled with your MySQL Enterprise Monitor installation.

Important

The JVM shipped with MySQL Enterprise Service Manager does not support the AES256 cipher. This can prevent you using LDAP servers which implement that cipher.

To connect to LDAP servers which implement the AES256 cipher, you must download and install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 8 package. This package is available from: Java Cryptography Extension.

The steps described in this section assume your LDAP server is correctly configured and you have a root CA certificate which was used to generate the LDAP server's certificate.

To enable SSL for LDAP and MySQL Enterprise Service Manager, you must do the following:

1. Convert the LDAP server's root CA certificate from PEM to DER format, if necessary. If the CA certificate is already in DER format, continue to the next step.

     openssl x509 -in cacert.pem -inform PEM -out ~/cacert.der -outform DER

2. Import the CA certificate, in DER format, into the MySQL Enterprise Service Manager Java keystore. Run the following command from the bin directory of your MySQL Enterprise Service Manager's Java installation:

     keytool -import -trustcacerts -alias ldapssl -file ~/cacert.der -keystore lib/security/cacerts

3. Restart MySQL Enterprise Service Manager with the following command:

     mysql/enterprise/monitor/mysqlmonitorctl.sh restart
