The invention discloses a method and device for realizing load balancing, wherein the method includes: receiving a domain name resolution request, judging whether the pre-created shared status bit is in the status of an existing process and performing domain name resolution; if not, modifying the shared status bit It is the state that the domain name resolution is being performed by the existing process, and the domain name resolution is performed on the received domain name resolution request; if it is, wait until it is determined that the shared status bit is the state that the non-existing process is performing domain name resolution, and then modify the shared status bit to exist. In the state of domain name resolution, the domain name resolution is performed on the received domain name resolution request; after the domain name resolution is completed, the control sharing status bit returns to the state that no process is in progress of domain name resolution. The above technical solution ensures that only one domain name resolution is in progress at the same time through the state constraint of the shared status bits, so that the domain name resolution can be executed according to a preset load balancing strategy to achieve load balancing.
