NGINX actual HTTP Request processing flow is divided into 11 stages.

The reason for this division is to perform logical subdivision request to the module as a processing unit, the various stages can contain any number of HTTP modules and pipelined manner request.

The advantage of this is to make the process more flexible, reducing the degree of coupling.

These 11 HTTP stages are as follows：

1. NGX_HTTP_POST_READ_PHASE ― The phase of the read request;

# 生成 dhparam.pem 文件, 在命令行执行任一方法:

# 方法1: 很慢
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

# 方法2: 较快
# 与方法1无明显区别. 2048位也足够用, 4096更强
openssl dhparam -dsaparam -out /etc/nginx/ssl/dhparam.pem 4096

sudo yum update # update yum
sudo yum install centos-release-scl # install SCL
