准备3台服务器,一台做nginx负载均衡,两台为Apache的web服务器
1.首先源码安装nginx
配置nginx负载均衡和nginx负载均衡调度算法为加权轮询,加权轮询比例为1:3,下列代码有注释。
vim /usr/local/nginx/conf/nginx.conf
http { include mime.types; default_type application/octet-stream; #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 logs/access.log main; upstream webservers { #添加nginx反向代理 server 192.168.189.130 weight=1; #nginx需要代理的服务器,可以根据情况加端口 server 192.168.189.131 weight=3; #服务器2 } sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { proxy_pass http://webservers; #反向代理设置为web群组 }
为两台服务器创建测试页面
采用Apache服务,路径:
/var/www/html vim /var/www/html/index.html
web1 web2
测试访问nginx的ip,并测试负载均衡和加权轮询
可以看到1:3的web1/2出现次数
nginx负载均衡的日志:
tail -f /usr/local/nginx/logs/access.log
