How to achieve high availability of WEB services in PHP7.0?

In today's Internet era, WEB services have become an indispensable service in people's daily lives, and the high availability of WEB services is one of the issues that WEB service providers must pay attention to. How to achieve high availability of WEB services in PHP7.0?

1. Load balancing technology

Load balancing refers to allocating traffic to multiple WEB service nodes to ensure that each node bears reasonable traffic pressure, thereby improving service availability and performance. . In PHP7.0, you can use Nginx, Apache and other WEB servers to achieve load balancing. During configuration, client requests need to be distributed to multiple WEB server nodes to avoid any node failure causing service stoppage.

2. Database master-slave replication technology

Since back-end data storage in WEB services usually uses databases such as MySQL, and a single database node has the risk of failure, database master-slave replication technology can Avoid the risk of unavailability caused by single points of failure. In PHP7.0, you can build a MySQL master-slave replication environment to concentrate the write operations of the database on the master node and disperse the read operations to multiple slave nodes to achieve high availability.

3. Real-time monitoring technology

In order to quickly discover and solve problems, real-time monitoring technology is an essential technology. In PHP7.0, you can use Zabbix, Nagios and other monitoring tools to realize real-time monitoring of servers, WEB services, databases and other resources. Through real-time monitoring, problems such as node performance and load can be discovered in time, and corresponding measures can be taken to prevent the problem from expanding.

4. High availability architecture design

In PHP7.0, the high availability of WEB services can be ensured through reasonable architecture design. Factors such as system availability, system resources, and data consistency must be fully considered when designing the architecture. For example, the use of distributed, containerization and other technologies can realize the microservice architecture, and the introduction of containerization technologies such as Docker can provide unified management of services and rapid expansion to cope with traffic pressure during peak business periods.

In short, improving the high availability of WEB services requires consideration from many aspects, such as monitoring and protecting the system through technologies such as load balancing, database master-slave replication, and real-time monitoring. In PHP7.0, high-availability architecture design is also a very important link. Only on the basis of high availability can WEB services provide better user experience and service quality while ensuring stability.
