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:

代码如下 复制代码

user nginx;

worker_processes auto;

error_log/var/log/nginx/error.log;

pid/run/nginx.pid;

events {

worker_connections 1024;

}

http {

log_format main'$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;

sendfile on;

tcp_nopush on;

tcp_nodelay on;

keepalive_timeout 65;

types_hash_max_size 2048;

include blockip.conf; #过虑IP

include /etc/nginx/mime.types;

default_type application/octet-stream;

# Load modular configuration files from the /etc/nginx/conf.d directory.

# See http://ng*inx**.org/en/docs/ngx_core_module.html#include

# for more information.

include/etc/nginx/conf.d/*.conf;

upstream www.域名.com {

server IP1:端口; #服务器1

server IP2:端口; #服务器2

ip_hash; #负载均衡的规则

}

server {

listen 80 default_server; #NGINX 指向的服务域名

listen [::]:80 default_server;

server_name IP; #NGINX 指向的服务器 IP

root /usr/share/nginx/html;#NGINX HTML 目录

# Load configuration files for the default server block.

include/etc/nginx/default.d/*.conf;

location / {

proxy_pass http://www.**域*名.com;#nginx指向的域名

}

error_page 404/404.html;

location =/40x.html { #404页面

}

error_page 500 502 503 504/500.html;

location =/500.html { #500页面

}

}

}
