To use SSL connections between the MySQL server and client programs, your system must support either OpenSSL or yaSSL:
MySQL Enterprise Edition binary distributions are compiled using yaSSL.
MySQL Community Edition binary distributions are compiled using yaSSL.
MySQL Community Edition source distributions can be compiled using either OpenSSL or yaSSL.
If you compile MySQL from a source distribution, CMake configures the distribution to use yaSSL by default. To compile using OpenSSL instead, use this procedure:
Ensure OpenSSL 1.0.1 or higher is installed on your system. To obtain OpenSSL, visit http://www.openssl.org.
To use OpenSSL, add the
-DWITH_SSL=systemoption to the CMake command you normally use to configure the MySQL source distribution. For example:
cmake . -DWITH_SSL=system
That command configures the distribution to use the installed OpenSSL library. See Section 2.9.4, “MySQL Source-Configuration Options”.
Compile and install the distribution.
mysql> SHOW VARIABLES LIKE 'have_ssl'; +---------------+-------+ | Variable_name | Value | +---------------+-------+ | have_ssl | YES | +---------------+-------+
If the value is
YES, the server supports
encrypted connections. If the value is
DISABLED, the server is capable of supporting
encrypted connections but was not started with the appropriate
--ssl- options to
enable encrypted connections to be used; see
Section 6.4.1, “Configuring MySQL to Use Encrypted Connections”.
