nginx常用技术指南读后感二

十二、负载均衡
1、nginx负载均衡基础知识
nginx的upstream目前支持四种方式的分配
简单的负载无衡实例：
vi nginx.conf
......
#loadblance my.linuxtone.org
         upstream    my.linuxtone.org {
         ip_hash;
         server    127.0.0.1:8080;
server    192.168.169.136:8080;
server    127.0.0.1:8080;
server    127.0.0.1:8080;
server    127.0.0.1:8080;
server    127.0.0.1:8080;
}
.............................
include    vhosts/linuxtone_lb.conf
.............................

#vi proxy.conf
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X_Real_IP $remote_addr;
proxy_set_header X_Forwarded-For $proxy_add_x_forwardr_for;
client_max_body_size 50m;
client_body_buffer_size 256k;
proxy_connect_timeout 30;
proxy_send_timeout 30;
proxy_read_timeout 60;

proxy_buffer_size  4k;
proxy_buffers 432k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
proxy_max_temp_file_size 128m;
proxy_store on;
proxy_store_access   user:rw  group:rw  all:r;
#nginx cache
#client_body_temp_path  /data/nginx_cache/client_body 1 2;
proxy_temp_path /data/nginx_cache/proxy_temp 1 2;

#vi linuxtone_lb.conf
server{
    listen 80;
    server_name my.linuxtone.org;
    index index.php;
    root /data/www/wwwroot/mylinuxone;
    if(-f $request_filename){
       break;
    }
    if(-f $request_filename/index.php){
      rewrite(.*)$1/index.php break;
     }
  
   error_page 403
   location /{
     if(!-e $request_filename){
         proxy_pass
         break;
     }
     include /usr/local/nginx/conf/proxy.conf;
   }
}
