Data synchronization method of main application server, storage medium and electronic equipment

The invention discloses a data synchronization method of a main application server. The method comprises the following steps: analyzing an instruction sent by external equipment and obtaining a plurality of types of instruction data; each type of instruction data is to be synchronized to a target; generating a plurality of log files according to each target; each log file comprises a generation timestamp of the file and a host name of a target; generating an index file according to all the log files corresponding to the same target; each index file comprises a host name of a target, current write file information and current synchronization information; obtaining a to-be-written log file according to the host name of the target and the current write file information so as to write corresponding instruction data into the to-be-written log file; obtaining a to-be-synchronized log file according to the host name of the target and the current synchronization information to read instruction data written in the to-
