??10 ?host2
data_source "cluster2" ??10 ?host6
data_source "cluster3" ??10 ?host8

/etc/init.d/gmetad restart
?
下面要分别指定节点使用的端口：
cluster1：
vi /etc/ganglia/gmond.conf
指定集群名称：
cluster {? name = "cluster1"? owner ="unspecified"? latlong ="unspecified"? url ="unspecified"}
指定端口：
udp_send_channel {? mcast_join = 239.2.11.71? port = 8661? ttl = 1}udp_recv_channel {? mcast_join =239.2.11.71? port = 8661? bind =239.2.11.71}
/etc/init.d/ganglia-monitor? restart
?
cluster2：
vi /etc/ganglia/gmond.conf
指定集群名称：
cluster {? name = "cluster2"? owner ="unspecified"? latlong ="unspecified"? url ="unspecified"}
指定端口：
udp_send_channel {? mcast_join =239.2.11.71? port = 8662? ttl = 1}udp_recv_channel {? mcast_join =239.2.11.71? port = 8662? bind =239.2.11.71}
/etc/init.d/ganglia-monitor? restart
?
cluster3:
vi /etc/ganglia/gmond.conf
指定集群名称：
cluster {? name = "cluster3"? owner ="unspecified"? latlong ="unspecified"? url ="unspecified"}
指定端口：
udp_send_channel {? mcast_join =239.2.11.71? port = 8663? ttl = 1}udp_recv_channel {? mcast_join =239.2.11.71? port = 8663? bind =239.2.11.71}
/etc/init.d/ganglia-monitor? restart
?
2、Ganglia以单播方式监控同一个网段中的多个集群
vi? /etc/ganglia/gmetad.conf
data_source "cluster1" ??10 ?host2
data_source "cluster2" ??10 ?host6
data_source "cluster3" ??10 ?host8
?
/etc/init.d/gmetad restart
?
cluster1：
vi /etc/ganglia/gmond.conf
指定集群名称：
cluster {? name = "cluster1"? owner = "unspecified"? latlong ="unspecified"? url ="unspecified"}
指定接收数据的节点：
udp_send_channel {
? # mcast_join = 239.2.11.71
? host = host2
? port = 8649
? ttl = 1
}
udp_recv_channel {
? # mcast_join = 239.2.11.71
? port = 8649
? # bind = 239.2.11.71
}
/etc/init.d/ganglia-monitor? restart
?
?
cluster2：
vi /etc/ganglia/gmond.conf
指定集群名称：
cluster {? name = "cluster2"? owner ="unspecified"? latlong ="unspecified"? url ="unspecified"}
指定接收数据的节点：
udp_send_channel {
? # mcast_join = 239.2.11.71
? host = host6
? port = 8649
? ttl = 1
}
udp_recv_channel {
? # mcast_join = 239.2.11.71
? port = 8649
? # bind = 239.2.11.71
}
/etc/init.d/ganglia-monitor? restart
?
?
cluster3：
vi /etc/ganglia/gmond.conf
指定集群名称：
cluster {? name = "cluster3"? owner ="unspecified"? latlong ="unspecified"? url ="unspecified"}
指定接收数据的节点：
udp_send_channel {
? # mcast_join = 239.2.11.71
? host = host8
? port = 8649
? ttl = 1
}
udp_recv_channel {
? # mcast_join = 239.2.11.71
? port = 8649
? # bind = 239.2.11.71
}
/etc/init.d/ganglia-monitor? restart
3、Ganglia监控不同网段中的多个集群
不同网段中的主机如果属于同一个集群，则无法使用ganglia的多播配置方法，必须使用单播。
下面把host226加入cluster1：
在host226上安装数据收集服务：
创建用户和组：
addgroup ?ganglia
adduser ?--ingroup ?ganglia ?ganglia
安装：
apt-get ?install? ?ganglia-monitor
配置gmond：
vi/etc/ganglia/gmond.conf
先找到setuid= yes,改成setuid=no;
在找到cluster块中的name，改成name=”cluster1”;
指定端口(要注意刚才第一步演示组播的时候已经把UDP端口改为8661)：
udp_send_channel {? mcast_join = 239.2.11.71? port = 8661? ttl = 1}udp_recv_channel {? mcast_join =239.2.11.71? port = 8661? bind =239.2.11.71}
重启服务：
/etc/init.d/ganglia-monitor? restart
