本文介绍使用ha和lvs部署负载均衡环境,希望对于初学Nginx服务器相关的朋友有帮助,更多Nginx安装、配置、报错处理等资源请本站内搜索。。
公司发展的需求,先在本地做测试,把测试步骤贴出来。

------------------------------------------------

环境说明:

VirtualBOX 

ubuntu-real1  192.168.1.201

ubuntu-real2  192.168.1.202

Centos        192.168.1.202

VIP           192.168.1.200

# 安装Ubuntu 10 Server  Centos 

# 克隆Ubuntu     ubuntu-real1   ---ubuntu-real2

# 克隆完后 会出现网络无法启动

sudo mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.old

Reboot

#设置静态IP

vim /etc/network/interfaces

auto eth0

iface eth0 inet static    

address 192.168.1.201

netmask 255.255.255.0

gateway 192.168.1.1

/etc/init.d/networking restart

#结束个用户 

pkill -9 -t pts/0

# 更换源  (不一定需要操作 )

apt-key adv --keyserver keyserver.Ubuntu.com --recv-keys C300EE8C
