<b>Nginx+Keepalived在Ubuntu上实现负载均衡</b>[服务器安全]

1、nginx反向代理配置

翻开/etc/nginx/nginx.conf配置文件,在http下加入:



upstream ip{ #对外虚拟IP

server IP1;

server IP2;

}

server{

listen 80;

server_name ip; #i对外虚拟IP

index index.php;index.html;index.htm;

location / {

proxy_pass http://ip;

}

}

2、keepalived的配置

1安装Keepalived

sudo apt-get install keepalived

2配置keepalived

将IP1作为负载均衡的主服务器,将IP2作为“从服务器”.这是通过配置文件中的priority来实现的.在“主服务器”上设置为:101,“从服务器”上设置为:100.

在IP1上,设置/etc/keepalived/keepalived.conf

$ sudo nano /etc/keepalived/keepalived.conf

vrrp_script chk_haproxy{

script "killall -0 haproxy"

interval 2

weight 2

}

vrrp_instance VI_1 {

interface eth0

state MASTER

virtual_router_id 51

priority 101 #101为“主”,100为“从”

virtual_ipaddress {

ip #对外虚拟IP

}

track_script {

chk_haproxy

}

}

运行keepalived服务

suto /etc/init.d/keepalived start

IP2和IP1的配置基本上一样,只需求把优先级该成:100 　　以上是“<b>Nginx+Keepalived在Ubuntu上实现负载均衡</b>[服务器安全]”的内容，如果你对以上该文章内容感兴趣，你可以看看七道奇为您推荐以下文章：
