The following list shows some of the most common server options. Additional options are described in
other sections:
• Options that affect security: See
• SSL-related options: See
• Binary log control options: See
• Replication-related options: See
Variables".
• Options specific to particular storage engines: See
Section 14.5.3, "BDB
Variables", and Section 17.3.4.2,
You can also set the values of server system variables by using variable names as options, as
described at the end of this section.
Some options control the size of buffers or caches. For a given buffer, the server might need to allocate
internal data structures. These structures typically are allocated from the total memory allocated to
the buffer, and the amount of space required might be platform dependent. This means that when you
assign a value to an option that controls a buffer size, the amount of space actually available might
differ from the value assigned. In some cases, the amount might be less than the value assigned. It is
also possible that the server will adjust a value upward. For example, if you assign a value of 0 to an
option for which the minimal value is 1024, the server will set the value to 1024.
Values for buffer sizes, lengths, and stack sizes are given in bytes unless otherwise specified.
Some options take file name values. Unless otherwise specified, the default file location is the data
directory if the value is a relative path name. To specify the location explicitly, use an absolute path
name. Suppose that the data directory is /var/mysql/data. If a file-valued option is given as a
relative path name, it will be located under /var/mysql/data. If the value is an absolute path name,
its location is as given by the path name.
