Nginx がセッション永続性を実装する方法は何ですか?

在Nginx代理服务器（负载均衡服务器）中配置：===========================================upstream test {   ip_hash;      server 10.20.151.112:80;      server 10.20.151.113:80;}

yum install -y pcre* openssl* gcc gcc-c++ make   --安装编译环境
wget  https://bitbucket.org/nginx-goodies/nginx-sticky-module-ng/get/08a395c66e42.zip   --下载sticky模块
nginx -v  --查看Nginx版本，因为要下载和yum安装nginx对应版本的源码包
wget  http://nginx.org/download/nginx-1.18.0.tar.gz
yum install -y unzip   --安装解压工具
unzip 08a395c66e42.zip --解压模块包
mv nginx-goodies-nginx-sticky-module-ng-08a395c66e42/ nginx-sticky-module-ng/  --改名
tar xzvf nginx-1.18.0.tar.gz -C /usr/local/  --解压nginx的源码包
cd /usr/local/nginx-1.18.0/
nginx -V   --查看yum安装nginx所有模块

======================================================================================
make && make install
Nginx -V  --再次查看Nginx模块，添加成功

vim upstream.conf   --在子配置文件conf.d中创建upstream.conf
=====================================================================================
upstream qfedu {
        server 192.168.198.143;
        server 192.168.198.145;
        sticky;
}

vim proxy.conf     ----在子配置文件conf.d中创建proxy.conf
=====================================================================================
server {
    listen       80;
    server_name  localhost;
    
    location / {
        proxy_pass http://testweb;
    }
}

nginx -t    --检查配置文件语法是否有错
nginx -s reload   --重新加载配置文件
