Run different network services on different servers or virtual machines to reduce the impact of intrusion on other services. For example, if an attacker intrude into Apache, other services (such as MySQL and email services) on the same server can be accessed ). However, in the above example, it does
Planning for high availability in the EnterpriseLesson 1: Assessing database availability requirements1. Calculating availability(1) A = (F-(MR + r)/FA: AvailabilityF: Mean time between failuresMR: mean time to recognizeR: mean time to repair(2) availability is determined by how quickly you can recover a system after it has suffered a failure. some people call this disaster recovery. recovering a system form a failure is both disaster recovery and high availability.2.

#25: Separating services from different servers or virtual machines
For a relatively large installation configuration, we recommend that you separate the running, database, static, and dynamic content from different servers.
Run different network services on different servers or virtual machines to reduce the impact of intrusion on other services. For example, if an attacker intrude into Apache, other services (such as MySQL an

The program is as follows (this example program is stored in biz.1cn.stream, and the testfile.txt file is created in the root directory for normal operation ):
