nginx负载均衡配置和nginx+keepalived负载均衡高可用

负载均衡端：192.168.163.130

     web1：192.168.163.129

负载均衡端配置：

[Shell] 纯文本查看 复制代码

worker_processes 1;
events {
worker_connections 1024;
}
http{
upstream myproject {
server 192.168.163.129:80;
}
server {
listen 80;
location / {
proxy_pass http://myproject;
}
}
}

web1配置这里不多解释

测试：在/var/www/html下分别在129和130生成index.html文件

分别写入其IP，方便测试

访问192.168.163.130

显示129说明分发成功。

当然现实的情况下我们要避免单点故障，我们这里使用nginx+keepalived来实现

虚拟IP为：192.168.163.100

安装keepalived

ld1#tar fvxz keepalived-1.1.17.tar.gz

ld1#yum install kernel-devel openssl-devel -y (不装一会安装会有问题)

ld1#ln -s /usr/src/kernels/2.6.18-238.el5-i686/ /usr/src/linux 路径用TAB补全，因为内核版本不同

cd keepalived-1.1.17

./configure --prefix=/usr/local/keepalived

make

make install

安装后，把人家提供好的文件进行对应的复制！

ld1#cp /usr/local/keepalived/etc/rc.d/init.d/keepalived  /etc/init.d/

ld1#cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

ld1#mkdir -pv /etc/keepalived

mkdir: 已创建目录 “/etc/keepalived”

ld1#cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

ld1#ln -s /usr/local/keepalived/sbin/keepalived /sbin/

定义配置文件

vi /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

notification_email {

       284648979@qq.com

  }

  notification_email_from 284648979@qq.com

  smtp_server smtp.hysec.com

  smtp_connect_timeout 30

  router_id nginx_master

}

vrrp_instance VI_1 {

   state MASTER

   interface eth0

   virtual_router_id 51

   priority 101

   advert_int 1

   authentication {

       auth_type PASS

       auth_pass 1111

   }

   virtual_ipaddress {

       192.168.163.100

   }

}

启动服务

/etc/init.d/keepalived  start

用ifconfig看不到虚IP，要用ip add sh 查看
