nginx五种负载均衡算法实现方式

1、轮询

upstream test {

         server 192.168.1.160:80;

         server 192.168.1.167:80;

               }

2、for i in $(seq 100); do curl http://192.168.1.43;done>1.txt

root@fabu-10-221:~# cat 1.txt |grep "192.168.1.160"|wc -l

50

root@fabu-10-221:~# cat 1.txt |grep "192.168.1.167"|wc -l

50

3、weight

upstream test {

         server 192.168.1.160:80  weight=1;

         server 192.168.1.167:80  weight=5;

               }

4、100刚好是20的5倍

5、ip_hash

upstream test {

         ip_hash;

         server 192.168.1.160:80;

         server 192.168.1.167:80;

               }

6、root@fabu-10-221:~# cat 1.txt |grep "192.168.1.167"|wc -l

120

root@fabu-10-221:~# cat 1.txt |grep "192.168.1.160"|wc -l

0

root@fabu-10-221:~# for i in $(seq 120); do curl http://192.168.1.43;done >1.txt 

结果锁定在同一台机器上

7、fair

upstream test {

         server 192.168.1.160:80;

         server 192.168.1.167:80;

         fair;
