vim /etc/ganglia/gmetad.conf
# 修改 data_source，这里也就是cluster的名字了，具体说明看配置文件内的介绍
data_source "my cluster"
vim /etc/ganglia/gmond.conf
# 修改 cluster name
cluster {
name = "k8s-spark"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
/* The host section describes attributes of the host, like the location */
host {
location = "unspecified"
}

used to only support having a single channel */

3.编辑从节点gmond.conf
cluster {
name = "k8s-spark"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
/* The host section describes attributes of the host, like the location */
host {
location = "unspecified"
}
/* Feel free to specify as many udp_send_channels as you like. Gmond
used to only support having a single channel */
udp_send_channel {
bind_hostname = yes（这个是否要查看从节点，如果注释则只能看到主节点） # Highly recommended, soon to be default.
# This option tells gmond to use a source address
# that resolves to the machine's hostname. Without
# this, the metrics may appear to come from any
# interface and the DNS names associated with
# those IPs will be used to create the RRDs.
#mcast_join = 239.2.11.71
host = 192.168.66.30
port = 8649
ttl = 1
}
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
# mcast_join = 239.2.11.71
port = 8649
# Size of the UDP buffer. If you are handling lots of metrics you really
# should bump it up to e.g. 10MB or even higher.
# buffer = 10485760
}
/* You can specify as many tcp_accept_channels as you like to share
an xml description of the state of the cluster */
tcp_accept_channel {
port = 8649
# If you want to gzip XML output
gzip_output = no
}
/* Channel to receive sFlow datagrams */
#udp_recv_channel {
# port = 6343
#}
4.将安装完成的ganglia软连接到/var/www/中
ln -s /usr/share/ganglia /var/www/
4.nginx服务器配置ganglia页面
打开php-fpm后，在/etc/php-fpm.d/www.conf中可以看到listen，将这个改为空闲端口
编写ganglia的网页文件
vim /usr/local/websites/sites-enabled/ganglia
server {
listen 9255;(你要在网页查看的端口）
server_name 192.168.66.30;（主节点ip）
index index.html index.htm index.php;
root /var/www/ganglia;（软连接目录）
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9600; （监听的php端口）
fastcgi_index index.php;
include fastcgi_params;
include fastcgi.conf;
}
}
