32位色与24位色

一、环境：

redhat5.4、keepalived-1.1.17、nginx-1.0.6

主nginx负载均衡器：192.168.0.10

辅nginx负载均衡器：192.168.9.20

vip：192.168.0.100
二、keepalived部署
1.下载最新稳定版 wget http://www.keepalived.org/software/keepalived-1.1.17.tar.gz
2.安装keepalived
tar zxvf keepalived-1.1.17.tar.gz

cd keepalived-1.1.17

./configure –prefix=/usr/local/keepalive

make ; make install
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
3.配置keepalived
#master配置

mkdir /etc/keepalived

vim /etc/keepalived/keepalived.conf
global_defs {

smtp_server 127.0.0.1

smtp_connect_timeout 30

router_id LVS_DEVEL

}

vrrp_instance VI_1 {

state MASTER

interface eth0

virtual_router_id 51

#backup ipaddress

mcast_src_ip 192.168.0.20

priority 100

advert_int 1

authentication {

auth_type PASS

auth_pass ufsoft

}

virtual_ipaddress {

192.168.0.100

}

}
#backup配置

mkdir /etc/keepalived

vim /etc/keepalived/keepalived.conf
global_defs {

smtp_server 127.0.0.1

smtp_connect_timeout 30

router_id LVS_DEVEL

}

vrrp_instance VI_1 {

state BACKUP

interface eth0

virtual_router_id 51

#master ipaddress

mcast_src_ip 192.168.0.10

priority 50

advert_int 1

authentication {

auth_type PASS

auth_pass ufsoft

}

virtual_ipaddress {

192.168.0.100

}

}
通过命令：#ip a 来检查

启动keepalived：

keepalived -f /etc/keepalived/keepalived.conf -D

//-f指定了keepalived的配置文件位置

三、nginx部署
