How to solve the pitfall of nginx configuration add_header

How to solve the pitfall of nginx configuration add_header

Preface add_header is an instruction defined in the headers module. As the name suggests, it is used to add http response headers. But please note that it is just "adding", not rewriting. So if a header already exists, problems will arise if you use add_header again. Moreover, in lower versions of nginx, add_header does not support use in error pages. This is an instruction with many pitfalls. Its processing stage is later than location processing. Although it can be written in location, if another location is rewritten, the unprocessed add_header in the previous location will be lost. For example: location

How to optimize Nginx and Node.js for high-load networks

How to optimize Nginx and Node.js for high-load networks

If network optimization does not first understand the underlying transmission mechanisms of nginx and node.js and carry out targeted optimization, no matter how detailed the optimization of the two is, it may be in vain. Generally, nginx connects the client and upstream applications through tcpsocket. Our system has many thresholds and restrictions for tcp, which are set through kernel parameters. The default values ​​of these parameters are often set for general purposes and cannot meet the high traffic and short life requirements of web servers. Here are some parameters that are candidates for tuning tcp. To make them effective, you can place them in the /etc/sysctl.conf file, or put them in a new configuration file, such as /etc/sysctl.
