详解Linux系统配置nginx的负载均衡
负载均衡的几种方式:
1.轮询:默认按照时间顺序对所有服务器一个一个的访问,如果有服务器宕机,会自动剔除;
2.weight:服务器的方位几率和weight成正比,这个可以在服务器配置不均的时候进行配置;
3.ip_hash:对每个请求的ip进行hash计算,并按照一定的规则分配对应的服务器(可解决session共享);
4.fair:按照每台服务器的响应时间(rt)来分配请求,rt知道优先分配;
5.url_hash:按照访问url的hash值来分配请求;
NGINX配置文件:
?

/var/log/nginx/error
.log;
pid
/run/nginx
.pid;
events {
worker_connections 1024;
}

'$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"'
;
access_log
/var/log/nginx/access
.log main;
