Ganglia的安裝與部署

一、安裝依賴和環境

1. 安裝httpd服務與php

sudo yum -y install httpd php
           

1. 安裝其他依賴

sudo yum -y install rrdtool perl-rrdtool rrdtool-devel
sudo yum -y install apr-devel
           

1. 安裝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. 修改配置檔案/etc/httpd/conf.d/ganglia.conf

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

修改為如下：（未注釋部分）

1. 修改配置檔案/etc/ganglia/gmetad.conf

sudo vim /etc/ganglia/gmetad.conf
           

修改為：

1. 修改配置檔案/etc/ganglia/gmond.conf

sudo vim /etc/ganglia/gmond.conf
           

修改為：

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 （此處一定要注釋）
  host = 192.168.1.102（此處設定你自己的ip位址）
  port = 8649
  ttl = 1
}
           

udp_recv_channel {
  # mcast_join = 239.2.11.71（此處一定要注釋）
  port = 8649
  bind = 192.168.1.102 （此處設定你自己的ip位址）
  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
}
           

1. 修改配置檔案/etc/selinux/config

sudo vim /etc/selinux/config
           

修改為：

SELINUX=disabled
           

1. 重新開機
2. 啟動ganglia

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

如果完成以上操作依然出現權限不足錯誤，請修改/var/lib/ganglia目錄的權限：

sudo chmod -R 777 /var/lib/ganglia
           

1. 打開網頁浏覽ganglia頁面

   http://192.168.173.102/ganglia （請更換自己的ip位址）
