本文操作是在CentOS7下操作的

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
   sudo yum -y install epel-release
   sudo yum -y install ganglia-gmetad
   sudo yum -y install ganglia-web
   sudo yum install -y ganglia-gmond
4. 修改配置文件ganglia.conf
   sudo vim /etc/httpd/conf.d/ganglia.conf

#
# Ganglia monitoring system php web frontend
#
Alias /ganglia /usr/share/ganglia
<Location /ganglia>
  Require all granted
  # Require local
  # Require ip 10.1.2.3
  # Require host example.org
</Location>

5. 修改配置文件gmetad.conf
   sudo vim /etc/ganglia/gmetad.conf
   修改，其中hadoop-101是主机名，192.168.114.101是ip
   data_source "hadoop-101" 192.168.114.101
6. 修改配置文件gmond.conf
   sudo vim /etc/ganglia/gmond.conf
   修改为，主机名和ip与上面配置一致

cluster {
  name = "hadoop-101"
  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
  host = 192.168.114.101
  port = 8649
  ttl = 1
}
udp_recv_channel {
  # mcast_join = 239.2.11.71
  port = 8649
  bind = 192.168.114.101
  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
}

7. 修改配置文件config
   sudo vim /etc/selinux/config
   修改为
   SELINUX=disabled
   注意，selinux本次生效关闭必须重启，如果此时不想重启，可以执行下面命令临时生效之
   sudo setenforce 0
8. 启动ganglia
   sudo service httpd start
   sudo service gmetad start
   sudo service gmond start
9. 打开网页浏览ganglia页面
   192.168.114.101/ganglia
   注意，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，执行下面命令
   sudo chmod -R 777 /var/lib/ganglia

操作Flume测试监控

1. 修改/opt/module/flume/conf目录下的flume-env.sh配置
   export JAVA_OPTS="-Dflume.monitoring.type=ganglia -Dflume.monitoring.hosts=192.168.9.102:8649 -Xm
   s100m -Xmx200m"
2. 启动flume任务
   bin/flume-ng agent --conf conf/ --name a1 --conf-file job/flume-telnet-logger.conf -Dflume.root.logger==INFO,console -Dflume.monitoring.type=ganglia -Dflume.monitoring.hosts=192.168.114.100:8649

3. 查看监控结果
