nginx负载均衡器中主机的配置过程

对于一些企业，我们不用花费大把的资金去购进负载均衡设备，也可以进行负载均衡的实现。现在我们来说一下nginx负载均衡器，这种适合于中小型企业的设备，同样可以达到负载平衡的效果，现在我们就来介绍一下nginx负载均衡器的相关安装和设置问题。

一､拓扑环境:

用途 IP

主nginx负载均衡器 192.168.0.154

辅nginx负载均衡器 192.168.0.155

VIP地址 192.168.0.188

二､安装keepalived

wgethttp://www.keepalived.org/software/keepalived-1.1.15.tar.gz 
tarzxvfkeepalived-1.1.15.tar.gz cdkeepalived-1.1.15 
./configure--prefix=/usr/local/keepalived make 
makeinstall cp/usr/local/keepalived/sbin/keepalived/usr/sbin/ 
cp/usr/local/keepalived/etc/sysconfig/keepalived/etc/sysconfig/ cp/usr/local/keepalived/etc/rc.d/init.d/keepalived/etc/init.d/ 
mkdir/etc/keepalived cd/etc/keepalived/ 
vimkeepalived.conf 
!ConfigurationFileforkeepalived global_defs{ 
notification_email{ yuhongchun027@163.com 
} notification_email_fromkeepalived@chtopnet.com 
smtp_server127.0.0.1 smtp_connect_timeout30 
router_idLVS_DEVEL } 
vrrp_instanceVI_1{ stateMASTER

mcast_src_ip192.168.0.154<==主nginx负载均衡器的IP地址 priority100 
advert_int1 authentication{ 
auth_typePASS auth_passchtopnet

} #servicekeepalivedstart
