LVS+keepalived+nginx realizes dual-machine hot standby load balancing

LVS+Keepalived+Nginx realizes dual-machine hot standby load balancing, which is a high-availability load balancing deployment commonly used in enterprises. The network topology is as follows:

In the picture above, lvs+keepalived is used to load nginx and achieve high availability, and nginx then loads the tomcat web service (business service system) . Nodes at each level can be expanded horizontally.

We have already talked about lvs+keepalived in the previous section to achieve high availability load. This section mainly uses nginx load to expand the overall architecture to achieve better high availability, high load, and high concurrency. Regarding the load configuration of nginx, you can take a look at http://www.cnblogs.com/skyblue/archive/2013/05/14/3077334.html, which will not be tested here.

The above introduces LVS+keepalived+nginx to achieve dual-machine hot standby load balancing, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
