OpenStack collectd的从零安装客户端

1.查看是否需要增加yum 源

发现没有我们需要的collectd软件包。需要增加软件源epel.

可以知道已经有了我们需要的软件包。

安装collectd软件包

1	yum install collectd collect-*

这里可能会有下面的错误：

表示缺少这方面的包，如果没有该错误，请跳过下面的解决办法。

1	Requires: perl(URI::Escape)

表示perl程序没有URI::Escape包。 将其他标准版本的Centos的镜像里的/etc/yum.repo.d/Centos-Base.repo到这台新的计算节点。因为新的计算节点是使用的fuel-web的源，并且国内的163.sohu等源都不好用。 重新执行安装collectd-*程序正常。

验证collectd可用

编辑/etc/collectd.conf配置文件

启动服务

1	service collectd start

刷新:http://172.17.46.3:8084/的服务，可以看到服务可libvirt监控的虚拟机增加了。
