ganglia安装配置

一、安装 
1)安装httpd服务与php: sudo yum -y install httpd php  
2)安装其他依赖: sudo yum -y install rrdtool perl-rrdtool rrdtool-devel  
 sudo yum -y install apr-devel 
3)安装ganglia 
sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm 
sudo yum -y install ganglia-gmetad 
sudo yum -y install ganglia-web 
sudo yum -y install ganglia-gmond

二、配置 
1)vi /etc/httpd/conf.d/ganglia.conf 
#Ganglia monitoring system php web frontend 

#Alias/ganglia /usr/share/ganglia 

<Location/ganglia>

  Order deny,allow

  Deny from all

 Allow from all

  # Allow from 127.0.0.1

  # Allow from ::1

  # Allow from .example.com

</Location> 
2)vi /etc/ganglia/gmetad.conf 
data_source "linux" 192.168.216.20 
3)vi /etc/ganglia/gmond.conf 
cluster{

 name ="linux" (此处修改)

  owner = "unspecified"

  latlong = "unspecified"

  url = "unspecified"

}

udp_send_channel {

#bind_hostname= yes # Highly recommended, soon to be default.

                       # This option tellsgmond to use a source address

                       # that resolves to themachine's hostname.  Without

                       # this, the metrics mayappear to come from any

                       # interface and the DNS names associated with

                       # those IPs will be usedto create the RRDs.

  # mcast_join = 239.2.11.71

  host = 192.168.216.20   (此处修改)

  port = 8649

  ttl = 1

}

udp_recv_channel{

  # mcast_join = 239.2.11.71

  port = 8649

 bind = 192.168.216.20 (此处修改)

  retry_bind = true

  # Size of the UDP buffer. If you are handlinglots of metrics you really

  # should bump it up to e.g. 10MB or evenhigher.

  # buffer = 10485760

} 
3)vi /etc/selinux/config 
# Thisfile controls the state of SELinux on the system.

#SELINUX= can take one of these three values:

#     enforcing - SELinux security policy isenforced.

#     permissive - SELinux prints warningsinstead of enforcing.

#     disabled -No SELinux policy is loaded.

SELINUX=disabled

#SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes areprotected,

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

selinux本次生效关闭必须重启，如果此时不想重启，可以临时生效之:sudo setenforce 0 
5)启动ganglia 
sudo service httpd start 
sudo service gmetad start 
sudo service gmond start

http://192.168.216.20/ganglia 
如果完成以上操作依然出现权限不足错误，请修改/var/lib/ganglia目录的权限：sudo chmod -R 777 /var/lib/ganglia

修改/opt/module/flume-1.9.0/conf/flume-env.sh配置

JAVA_OPTS="-Dflume.monitoring.type=ganglia

-Dflume.monitoring.hosts=192.168.216.20:8649

-Xms100m

-Xmx200m"
