What this article shares to you is about the use of the standard time synchronization server in MySQL. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

The standard time synchronization server receives the satellite time signal, and the front panel displays the information such as the year, month, day, minute and second, the number of satellite collection, the working status of the system, the power supply status and so on, and transmits the standard UTC time information through the network to provide accurate, standard, safe, reliable and multi-functional ntp time correction service for network equipment.

The clock system consists of a GPS antenna and a time server, which are connected by a coaxial cable with a prefabricated BNC connector. The SYN2151 clock server is used with two 10max 100 / 1000Mb/s adaptive Ethernet interfaces, which can set different network segments for network timing of field equipment.

There are generally two ways of timing for standard time servers: point-to-point timing and hierarchical timing.

(1) in the point-to-point time mode, the external GPS clock server is set to the first NTPServer, and the system server is used as the second NTPServer. That is, all the devices of the system (controller, engineer station, operator station, etc.) are first synchronized with the GPS clock server. When the GPS is not working or the network is not working, the time is synchronized by the system server of Ovation itself. Because of the large number of clients, this method requires a high level of GPS clock server. It is precisely because all equipment directly give priority to timing, compared with the hierarchical timing mode, the danger is dispersed.

(2) the hierarchical timing mode sets the two computers of the system as the client of GPS, which is directly synchronized with GPS and serves as the NTPServer of other devices in the Ovation system. This method greatly reduces the burden of the GPS clock server, but has higher requirements for the operator station or engineer station of the NTP Server. SYN2151 clock server

Point-to-point timing mode and hierarchical timing mode have their own characteristics, and the scheme chosen depends on the performance and quality of the equipment selected, such as GPS clock server, operator station or engineer station. The choice of either way depends on the safe and reliable operation of the standard time server.

Installation and debugging process:

1. Connect the erected antenna to the antenna / ANT interface of the clock server, observe the front panel, and so on, after receiving the satellite, connect the network cable to the clock server and connect directly to the computer / local area network, and log in to the management interface of the device through software or WEB to configure.

2. Change the default IP and gateway in the server to the IP and gateway that are the same as the current local area network.

3, click on the time in the lower right corner of the computer, select "Internet time"-change the setting, select "Internet time server synchronization" in the input box to modify the default "time.windows.com" to the clock server modified IP, and click "Update now".

4. When you click "Update now" and indicate that the synchronization is successful, it means that the synchronization is successful. If the synchronization error is prompted, it means that the synchronization failed, and you need to check whether the IP is correct and the network is smooth.

5. After checking the IP and network lines, you need to check whether the windowstime function of the computer is enabled, in addition, check whether the NTP client function is enabled, fill in the IP of the clock server in the NTP configuration, and then click "Update now".

The above is how to use the standard time synchronization server in MySQL. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
