How does NGINX count the PV, UV, and independent IP of the website?
How does NGINX count the PV, UV, and independent IP of the website?
May 19, 2023 am 09:13 AM
概念：
uv(unique visitor)：獨立訪客，將每個獨立上網(wǎng)電腦（以cookie為依據(jù)）視為一位訪客，一天之內(nèi)（00:00-24:00），訪問您網(wǎng)站的訪客數(shù)量。一天之內(nèi)相同cookie的訪問只被計算1次
PV（頁面瀏覽量）是指用戶每次訪問網(wǎng)站時所產(chǎn)生的點擊量或頁面瀏覽量，記錄為1次。用戶對同一頁面的多次訪問，訪問量值累計
統(tǒng)計獨立ip：00:00-24:00內(nèi)相同ip地址只被計算一次,做網(wǎng)站優(yōu)化的朋友最關(guān)心這個
先聲明下環(huán)境，此次運行的nginx版本1.7，后端tomcat運行的是動態(tài)交互程序（需進行用戶認(rèn)證，如果是靜態(tài)頁面則抓不到cache值，$http_cookie是空值），就是這樣；
nginx日志文件配置
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - [$time_local] "$request" '
' - $status "user_cookie:$guid" ';
#user_cookie為日志顯示字符，$guid為變量，具體內(nèi)容在下面定義，也可在日志格式里寫入$http_cookie 顯示完整的cookie內(nèi)容<br>
sendfile on;
keepalive_timeout 65;
upstream backserver {
ip_hash;
server 1.1.2.2:8080;
server 1.1.2.3:8080;
}
server {
listen 80;
server_name localhost;
#if ( $http_cookie ~* "(.*)$") 匹配所有內(nèi)容
if ( $http_cookie ~* "csid=([a-z0-9]*)"){
set $guid $1;
} #只匹配csid字符信息，此處為正則表達式<br>
access_log logs/host.access.log main;
location ~* ^(.*)$ {
#limit_req zone=allips burst=1 nodelay;
proxy_pass http://backserver;
proxy_set_header host $host;
proxy_set_header x-real-ip $remote_addr;
proxy_set_header remote-host $remote_addr;
proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
client_max_body_size 8m;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}注：$http_cookie這個里面的值是一個一個cookie的值，中間以“;”分隔

[root@localhost logs]# grep index.shtml host.access.log | wc -l

Apr 21, 2025 am 12:08 AM
NGINX is more suitable for handling high concurrent connections, while Apache is more suitable for scenarios where complex configurations and module extensions are required. 1.NGINX is known for its high performance and low resource consumption, and is suitable for high concurrency. 2.Apache is known for its stability and rich module extensions, which are suitable for complex configuration needs.
NGINX and Apache: Understanding the Key Differences
Apr 26, 2025 am 12:01 AM
NGINX and Apache each have their own advantages and disadvantages, and the choice should be based on specific needs. 1.NGINX is suitable for high concurrency scenarios because of its asynchronous non-blocking architecture. 2. Apache is suitable for low-concurrency scenarios that require complex configurations, because of its modular design.
How to execute php code after writing php code? Several common ways to execute php code
May 23, 2025 pm 08:33 PM
PHP code can be executed in many ways: 1. Use the command line to directly enter the "php file name" to execute the script; 2. Put the file into the document root directory and access it through the browser through the web server; 3. Run it in the IDE and use the built-in debugging tool; 4. Use the online PHP sandbox or code execution platform for testing.
After installing Nginx, the configuration file path and initial settings
May 16, 2025 pm 10:54 PM
Understanding Nginx's configuration file path and initial settings is very important because it is the first step in optimizing and managing a web server. 1) The configuration file path is usually /etc/nginx/nginx.conf. The syntax can be found and tested using the nginx-t command. 2) The initial settings include global settings (such as user, worker_processes) and HTTP settings (such as include, log_format). These settings allow customization and extension according to requirements. Incorrect configuration may lead to performance issues and security vulnerabilities.
How to limit user resources in Linux? How to configure ulimit?
May 29, 2025 pm 11:09 PM
Linux system restricts user resources through the ulimit command to prevent excessive use of resources. 1.ulimit is a built-in shell command that can limit the number of file descriptors (-n), memory size (-v), thread count (-u), etc., which are divided into soft limit (current effective value) and hard limit (maximum upper limit). 2. Use the ulimit command directly for temporary modification, such as ulimit-n2048, but it is only valid for the current session. 3. For permanent effect, you need to modify /etc/security/limits.conf and PAM configuration files, and add sessionrequiredpam_limits.so. 4. The systemd service needs to set Lim in the unit file
What are the Debian Nginx configuration skills?
May 29, 2025 pm 11:06 PM
When configuring Nginx on Debian system, the following are some practical tips: The basic structure of the configuration file global settings: Define behavioral parameters that affect the entire Nginx service, such as the number of worker threads and the permissions of running users. Event handling part: Deciding how Nginx deals with network connections is a key configuration for improving performance. HTTP service part: contains a large number of settings related to HTTP service, and can embed multiple servers and location blocks. Core configuration options worker_connections: Define the maximum number of connections that each worker thread can handle, usually set to 1024. multi_accept: Activate the multi-connection reception mode and enhance the ability of concurrent processing. s
