Because the cluster involves Server Load balancer processing and requests need to be distributed among different machines, domain name resolution is required. In addition, machines in the cluster need to share the site configuration file and service configuration information, therefore, files must be shared between machines.

Summary of various DNS setup methods in the PDO connection database in PHP, Pdodns This paper summarizes the various DNS setting methods in the PDO connection database in PHP. Share to everyone for your reference, as follows: The DNS notation in PDO is as follows: MSSQL: Host=localhost;dbname=testdb Sybase: Host=local

DNS (Domain Name System) is a distributed database that maps domain names and IP addresses on the Internet, allowing users to access the Internet more conveniently, instead of remembering the number of IP address strings that can be directly read by machines. The process of obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution ). The
