负载均衡(Load Balancer,简称 LB)是指把客户端访问的流量通过负载均衡器,然后根据指定的一些负载均衡策略进行转发,最终可以均匀的分摊到后端上游服务器上,然后上游服务器进行响应后再返回数据给客户端。负载均衡的最常见应用是充当反向代理,通过负载均衡,可以大大的提高服务的响应速度、提高并发请求、提高稳定性(防止单点...
nginx:the configuration file/usr/local/nginx/conf/nginx.conf syntax is oknginx:configuration file/usr/local/nginx/conf/nginx.conf test is successful 7、测试基于cookie 现在我们可以通过发送一些请求来测试我们的基于cookie的负载均衡器是否正常工作。假设我们已经将DNS记录配置为将myloadbalancer.example.com解析...
The simplest configuration for load balancing with nginx may look like the following: http { upstream myapp1 { server srv1.example.com; server srv2.example.com; server srv3.example.com; } server { listen 80; location / { proxy_pass http://myapp1; ...
