下面都是在http{}里面进行配置

第一种配置:加权轮询,按服务器的性能给予权重

#负责压缩数据流gzip  on;  gzip_min_length   1000;  gzip_types        text/plain text/css application/x-javascript;#设定负载均衡的服务器列表#weigth参数表示权值，权值越高被分配到的几率越大upstream hello{    server 192.168.68.43:8080 weight=1;    server 192.168.68.45:8080 weight=1;            }   server {    #侦听的80端口    listen       80;    server_name  localhost;    #设定查看Nginx状态的地址    location /nginxstatus{         stub_status on;         access_log on;         auth_basic "nginxstatus";         auth_basic_user_file htpasswd;    }    #匹配以jsp结尾的，tomcat的网页文件是以jsp结尾    location / {        index index.jsp;        proxy_pass   http://hello;    #在这里设置一个代理，和upstream的名字一样            }}

第二种配置:ip_hash轮询方法,不可给服务器加权重

upstream lb {	server 192.168.196.130 fail_timeout=20s;	server 192.168.196.132 fail_timeout=20s;	ip_hash;} server {	 listen 80;	 server_name safexjt.com www.safexjt.com;	 index index.html index.htm index.php;	 location / {		 proxy_pass http://lb;		 proxy_next_upstream http_500 http_502 http_503 error timeout invalid_header;		 include proxy.conf;	 } }
