openstack中heat组件实现nginx负载均衡

前置操作

1.需要ceilometer监控服务以及alarm监控服务
2.可以将计算节点改造为http文件服务器,yum -y install httpd
特别注意装的是Apache2.4版本,默认没有文件列表,修改/etc/httpd/conf.d/welcome.conf

<LocationMatch "^/+$">
    Options +Indexes    修改这行
    ErrorDocument 403 /.noindex.html
</LocationMatch>

3.scp /etc/xiandian/* 192.168.100.20:/var/www/html/
4.虚拟机环境控制节点和云主机无法通信
vi /etc/sysconfig/network-scripts/ifcfg-be-ex

DEVICE=br-ex
DEVICETYPE=OVS
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=192.168.200.10
NETMASK=255.255.255.0

修改计算节点注释部分lb-server.yaml

vi /var/www/html/lb-server.yaml
