       mysql_ssl_rsa_setup - create SSL/RSA files

       mysql_ssl_rsa_setup [options]

       This program creates the SSL certificate and key files and RSA key-pair
       files required to support secure connections using SSL and secure
       password exchange using RSA over unencrypted connections, if those
       files are missing.  mysql_ssl_rsa_setup can also be used to create new
       SSL files if the existing ones have expired.

           mysql_ssl_rsa_setup uses the openssl command, so its use is
           contingent on having OpenSSL installed on your machine.

           Another way to generate SSL and RSA files, for MySQL distributions
           compiled using OpenSSL, is to have the server generate them
           automatically. See Section, "Creating SSL and RSA
           Certificates and Keys using MySQL".

           mysql_ssl_rsa_setup helps lower the barrier to using SSL by making
           it easier to generate the required files. However, certificates
           generated by mysql_ssl_rsa_setup are self-signed, which is not very
           secure. After you gain experience using the files created by
           mysql_ssl_rsa_setup, consider obtaining a CA certificate from a
           registered certificate authority.

       Invoke mysql_ssl_rsa_setup like this:

           mysql_ssl_rsa_setup [options]

       Typical options are --datadir to specify where to create the files, and
       --verbose to see the openssl commands that mysql_ssl_rsa_setup

       mysql_ssl_rsa_setup attempts to create SSL and RSA files using a
       default set of file names. It works as follows:

        1. mysql_ssl_rsa_setup checks for the openssl binary at the locations
           specified by the PATH environment variable. If openssl is not
           found, mysql_ssl_rsa_setup does nothing. If openssl is present,
           mysql_ssl_rsa_setup looks for default SSL and RSA files in the
           MySQL data directory specified by the --datadir option, or the
           compiled-in data directory if the --datadir option is not given.

        2. mysql_ssl_rsa_setup checks the data directory for SSL files with
           the following names:


        3. If any of those files are present, mysql_ssl_rsa_setup creates no
           SSL files. Otherwise, it invokes openssl to create them, plus some
           additional files:

               ca.pem               Self-signed CA certificate
               ca-key.pem           CA private key
               server-cert.pem      Server certificate
               server-key.pem       Server private key
               client-cert.pem      Client certificate
               client-key.pem       Client private key

           These files enable secure client connections using SSL; see
           Section 6.3.1, "Configuring MySQL to Use Encrypted Connections".

        4. mysql_ssl_rsa_setup checks the data directory for RSA files with
           the following names:

               private_key.pem      Private member of private/public key pair
               public_key.pem       Public member of private/public key pair

        5. If any of these files are present, mysql_ssl_rsa_setup creates no
           RSA files. Otherwise, it invokes openssl to create them. These
           files enable secure password exchange using RSA over unencrypted
           connections for accounts authenticated by the sha256_password
           plugin; see Section, "SHA-256 Pluggable Authentication".

       For information about the characteristics of files created by
       mysql_ssl_rsa_setup, see Section, "Creating SSL and RSA
       Certificates and Keys using MySQL".

       At startup, the MySQL server automatically uses the SSL files created
       by mysql_ssl_rsa_setup to enable SSL if no explicit SSL options are
       given other than --ssl (possibly along with ssl_cipher). If you prefer
       to designate the files explicitly, invoke clients with the --ssl-ca,
       --ssl-cert, and --ssl-key options at startup to name the ca.pem,
       server-cert.pem, and server-key.pem files, respectively.

       The server also automatically uses the RSA files created by
       mysql_ssl_rsa_setup to enable RSA if no explicit RSA options are given.

       If the server is SSL-enabled, clients use SSL by default for the
       connection. To specify certificate and key files explicitly, use the
       --ssl-ca, --ssl-cert, and --ssl-key options to name the ca.pem,
       client-cert.pem, and client-key.pem files, respectively. However, some
       additional client setup may be required first because
       mysql_ssl_rsa_setup by default creates those files in the data
       directory. The permissions for the data directory normally enable
       access only to the system account that runs the MySQL server, so client
       programs cannot use files located there. To make the files available,
       copy them to a directory that is readable (but not writable) by

       o   For local clients, the MySQL installation directory can be used.
           For example, if the data directory is a subdirectory of the
           installation directory and your current location is the data
           directory, you can copy the files like this:

               cp ca.pem client-cert.pem client-key.pem ..

       o   For remote clients, distribute the files using a secure channel to
           ensure they are not tampered with during transit.

       If the SSL files used for a MySQL installation have expired, you can
       use mysql_ssl_rsa_setup to create new ones:

        1. Stop the server.

        2. Rename or remove the existing SSL files. You may wish to make a
           backup of them first. (The RSA files do not expire, so you need not
           remove them.  mysql_ssl_rsa_setup sees that they exist and not
           overwrite them.)

        3. Run mysql_ssl_rsa_setup with the --datadir option to specify where
           to create the new files.

        4. Restart the server.

       mysql_ssl_rsa_setup supports the following command-line options, which
       can be specified on the command line or in the [mysql_ssl_rsa_setup],
       [mysql_install_db], and [mysqld] groups of an option file. For
       information about option files used by MySQL programs, see
       Section, "Using Option Files".

       o   --help, ?  Display a help message and exit.

       o   --datadir=dir_name The path to the directory that
           mysql_ssl_rsa_setup should check for default SSL and RSA files and
           in which it should create files if they are missing. The default is
           the compiled-in data directory.

       o   --suffix=str The suffix for the Common Name attribute in X.509
           certificates. The suffix value is limited to 17 characters. The
           default is based on the MySQL version number.

       o   --uid=name, -v The name of the user who should be the owner of any
           created files. The value is a user name, not a numeric user ID. In
           the absence of this option, files created by mysql_ssl_rsa_setup
           are owned by the user who executes it. This option is valid only if
           you execute the program as root on a system that supports the
           chown() system call.

       o   --verbose, -v Verbose mode. Produce more output about what the
           program does. For example, the program shows the openssl commands
           it runs, and produces output to indicate whether it skips SSL or
           RSA file creation because some default file already exists.

       o   --version, -V Display version information and exit.
