Murat,

In the above commandline you show cities.shb as the input.  This should
be cities.shp, perhaps this was just a typo if things worked?  Generally
speaking OGR depends on the .shp, .shx and .dbf file.  The .sbn and .sbx
spatial indexes are ignored.

You would use:

CONNECTIONTYPE OGR
CONNECTION "MySQL:testogr,user=root,password=passmysql"
DATA "cities"

for your layer.

Note that a true spatial table in MySQL is handled very differently from
a table with lat and lon columns which is usually handled via ODBC and
OVF.
