Ganglia的安装与部署

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

yum -y install epel-release
sudo yum -y install ganglia-gmetad 
sudo yum -y install ganglia-web
sudo yum install -y ganglia-gmond

二丶配置

1.修改配置文件/etc/httpd/conf.d/ganglia.conf

sudo vim /etc/httpd/conf.d/ganglia.conf

修改为如下：（未注释部分）

<Location /ganglia>Require all granted#Order deny,allow#Deny from all# Allow from 127.0.0.1# Allow from ::1# Allow from .example.com
</Location>

2.修改配置文件/etc/ganglia/gmetad.conf

sudo vim /etc/ganglia/gmetad.conf

修改为：

data_source "hadoop102" （192.168.173.102）#102的ip地址 自己根据自己的设定

3.修改配置文件/etc/ganglia/gmond.conf

sudo vim /etc/ganglia/gmond.conf

修改为：

cluster {name = "hadoop102"owner = "unspecified"latlong = "unspecified"url = "unspecified"
}

udp_send_channel {#bind_hostname = yes # 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 （此处一定要注释）host = 192.168.1.102（此处设置你自己的ip地址）port = 8649ttl = 1
}

udp_recv_channel {# mcast_join = 239.2.11.71（此处一定要注释）port = 8649bind = 192.168.1.102 （此处设置你自己的ip地址）retry_bind = true# 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
}

4.修改配置文件/etc/selinux/config

sudo vim /etc/selinux/config

修改为：

SELINUX=disabled

5.重启

6.启动ganglia

sudo service httpd start
sudo service gmetad start
sudo service gmond start

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

7.打开网页浏览ganglia页面
   http://192.168.173.102/ganglia （请更换自己的ip地址）
