A system and method for installing software with reduced downtime

摘要

A computer-implemented method (1) for installing software in a system comprising slave nodes (200) executing a slave server installer component (201) and a master node (100) executing a master server installer component (101), comprising:
- upgrading said master server installer component (101) on said master node (100) and said slave server installer component (201) on said slave nodes (200) without interrupting client service;
- installing said master server installer component (101) on said master node (100) without interrupting client service;
- preparing said master server installer component (101) without interrupting client service;
- distributing said slave server installer component (201) to said slave nodes (200) without interrupting client service;
- preparing said slave server installer component (201) without interrupting client service; and
- activating said master server installer component (101) without interrupting client service;
- activating said slave server installer component (201).
