openlitespeed-1.4.40.tgz is the pre-built package, extract and run install.sh to quickly install OpenLiteSpeed on Linux 64 bit platforms. If you need to change the default installation settings, update the ols.conf file before running install.sh.
Two special binaries, openlitespeed-1.4.40.asan and openlitespeed-1.4.40.dbg, are also provided for use when debugging special cases. The .dbg binary is useful when debugging crash issues while the .asan binary is better suited for debugging memory leak issues.
