Ganglia的安装与部署

1. 安装httpd服务与php
   
   

   # yum -y install httpd php

2. 安装其他依赖
   
   

   # yum -y install rrdtool perl-rrdtoolrrdtool-devel # yum -y install apr-devel

3. 安装ganglia
   
   

   # rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm # yum -y install ganglia-gmetad # yum -y install ganglia-web # yum install -y ganglia-gmond

4. 修改配置文件
   文件ganglia.conf:
   
   

   # vi/etc/httpd/conf.d/ganglia.conf 修改为： # #Ganglia monitoring system php web frontend #   Alias/ganglia /usr/share/ganglia     Order deny,allow   Deny from all   Allow from all   # Allow from 127.0.0.1   # Allow from ::1   # Allow from .example.com

   文件gmetad.conf：
   
   

   # vi /etc/ganglia/gmetad.conf 修改为： data_source "linux" 192.168.216.20

   文件gmond.conf：
   
   

   # vi /etc/ganglia/gmond.conf 修改为： cluster{   name ="linux"   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   port = 8649   ttl = 1 } udp_recv_channel{   # mcast_join = 239.2.11.71   port = 8649   bind = 192.168.216.20   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 }

   文件config：
   
   

   # vi /etc/selinux/config 修改为： # 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

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 打开网页浏览ganglia页面

配置Flume测试监控

修改flume-env.sh配置 JAVA_OPTS="-Dflume.monitoring.type=ganglia -Dflume.monitoring.hosts=192.168.216.20:8649 -Xms100m -Xmx200m" 启动flume任务 $ bin/flume-ngagent \ --confconf/ \ --namea1 \ --conf-filejob/group-job0/flume-telnet.conf \ -Dflume.root.logger==INFO,console \ $ bin/flume-ngagent \ --confconf/ \ --namea1 \ --conf-filejob/group-job0/flume-telnet.conf \ -Dflume.root.logger==INFO,console \
