worker_connections 设置可由? 一个 worker 进程同时打开的最? 大连接数
- events {
- worker_connections 2048;
- multi_accept on;
- use epoll;
- }
upstream 负载均衡列列表
weigth 表示权重, 权重越? 大分配? 比例例越?;
如下例子:
- upstream www.abc.com {
- server 192.168.16.3:8080 weight=1;
- server 192.168.26.3:8080 weight=2;
- server 192.168.36.3:8080 weight=3;
- }
- server
设置访问的负载均衡处理理的域名
server_name 代表域名, listen 代表监听的端口
location 配置域名下的路径地址
location 配置域可以配置? 一下静态? 文件的处理, 也可以配置请求的端口转发;
检查 nginx.conf 的正确性
nginx -t
nginx 重新载入配置文件
nginx -s reload
重启 nginx
