A method for managing network service, comprising: when a target server is in a self-controlled "ON" state, detecting, by the target server, an actual on-and-off state of a target network service every preset period of time, and acquiring, by the target server, a standard on-and-off state of the target network service from a control center; if the target server determines that the target network service needs to be turned off based on the standard on-and-off state and the actual on-and-off state, sending, by the target server, a service turn-off request of the target network service to the control center; if the control center determines that the target server is allowed to turn off the target network service, sending, by the control center, a service turn-off notification to the target server, and updating, by the control center, the standard on-and-off state of the target network service of the target server to an "off state; and after receiving the service turn-off notification, turning off, by the target server, the target network service, characterized in that if the control center determines that the target server is allowed to turn off the target network service, sending, by the control center, a service turn-off notification to the target server, and updating, by the control center, the standard on-and-off state of the target network service of the target server to an "off state, includes: after the target network service of the target server is turned off, if a turn-off ratio of target network services of all servers is smaller than a preset ratio threshold and a received number of service turn-off requests of the target network service sent by the target server is greater than a preset number threshold, allowing, by the control center, the target server to turn off the target network service, sending, by the control center, the service turn-off notification to the target server, and updating, by the control center, the standard on-and-off state of the target network service of the target server to the "off" state. when a target server is in a self-controlled "ON" state, detecting, by the target server, an actual on-and-off state of a target network service every preset period of time, and acquiring, by the target server, a standard on-and-off state of the target network service from a control center; if the target server determines that the target network service needs to be turned off based on the standard on-and-off state and the actual on-and-off state, sending, by the target server, a service turn-off request of the target network service to the control center; if the control center determines that the target server is allowed to turn off the target network service, sending, by the control center, a service turn-off notification to the target server, and updating, by the control center, the standard on-and-off state of the target network service of the target server to an "off state; and after receiving the service turn-off notification, turning off, by the target server, the target network service, characterized in that if the control center determines that the target server is allowed to turn off the target network service, sending, by the control center, a service turn-off notification to the target server, and updating, by the control center, the standard on-and-off state of the target network service of the target server to an "off state, includes: after the target network service of the target server is turned off, if a turn-off ratio of target network services of all servers is smaller than a preset ratio threshold and a received number of service turn-off requests of the target network service sent by the target server is greater than a preset number threshold, allowing, by the control center, the target server to turn off the target network service, sending, by the control center, the service turn-off notification to the target server, and updating, by the control center, the standard on-and-off state of the target network service of the target server to the "off" state.
