- Nginx performance optimization methods
- Linux System Parameter Optimization Some of the configurations mentioned below require a newer Linux (2.6 or above) kernel to support them. The author uses CentOS7.4, kernel version 3.10. If it does not meet the needs, it is best to upgrade accordingly. After all, patching is a thankless task. For system-level tuning, we usually just modify the file descriptor limit, buffer queue length, and number of temporary ports. File descriptor limit Since each TCP connection occupies a file descriptor, once the file descriptor is exhausted, a new connection will return an error such as "Toomanyopenfiles". In order to improve performance, we need to modify it: 1 .System level restrictions

- How to implement MySQL master-slave replication based on SSL secure connection
- There is a single point of failure in a mysql host in the production environment, so we need to ensure the high availability of mysql. That is, if one of the two MySQL servers hangs up, the other one can immediately take over its work. The principle of master-slave replication is that the master records the binary log. Before each transaction updates the data, the master records these changes in the secondary log. MySQL writes the transaction to the binary log. After the event is written to the binary log, the master notifies the storage engine to commit the transaction. The next step is for the slave to copy the master's binary log to its own relay log. First, the slave starts a worker thread—&
