Linux High-reliability technology

1, the process hangs dead, has the background monitoring program detection to pull up again.

2, the process occupies the system resources more than ulimit qualified resources, will be killed by Ulimit, at the same time with the background monitoring program, re-pull the process to achieve process reliability.

3, the high reliability of Linux system, is dependent on the Linux cluster, cluster is divided into 4-tier and based on 7-tier load balancing technology.

4, the Linux cluster relies on the LVS and Nginx, haproxy distribution, the reliability of the load balancer itself through the keepalive implementation.

5. The backend server of the Linux cluster is implemented by multiple devices.
