Ganglia的安装与部署

1&＃xff09;安装httpd服务与php

[atguigu&＃64;hadoop102 flume]$ sudo yum -y install httpd php

2&＃xff09;安装其他依赖

[atguigu&＃64;hadoop102 flume]$ sudo yum -y install rrdtool perl-rrdtool rrdtool-devel

[atguigu&＃64;hadoop102 flume]$ sudo yum -y install apr-devel

3&＃xff09;安装ganglia

[atguigu&＃64;hadoop102 flume]$ sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[atguigu&＃64;hadoop102 flume]$ sudo yum -y install ganglia-gmetad

[atguigu&＃64;hadoop102 flume]$ sudo yum -y install ganglia-web

[atguigu&＃64;hadoop102 flume]$ sudo yum install -y ganglia-gmond

4&＃xff09;修改配置文件/etc/httpd/conf.d/ganglia.conf

[atguigu&＃64;hadoop102 flume]$ sudo vim /etc/httpd/conf.d/ganglia.conf

修改为红颜色的配置&＃xff1a;

# 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

5&＃xff09;修改配置文件/etc/ganglia/gmetad.conf

[atguigu&＃64;hadoop102 flume]$ sudo vim /etc/ganglia/gmetad.conf

修改为&＃xff1a;

data_source “hadoop102” 192.168.9.102

6&＃xff09;修改配置文件/etc/ganglia/gmond.conf

[atguigu&＃64;hadoop102 flume]$ sudo vim /etc/ganglia/gmond.conf

修改为&＃xff1a;

cluster {

  name &＃61; “hadoop102”

  owner &＃61; “unspecified”

  latlong &＃61; “unspecified”

  url &＃61; “unspecified”

}

udp_send_channel {

  #bind_hostname &＃61; 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 &＃61; 239.2.11.71

  host &＃61; 192.168.9.102

  port &＃61; 8649

  ttl &＃61; 1

}

udp_recv_channel {

  # mcast_join &＃61; 239.2.11.71

  port &＃61; 8649

  bind &＃61; 192.168.9.102

  retry_bind &＃61; 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 &＃61; 10485760

}

7&＃xff09;修改配置文件/etc/selinux/config

[atguigu&＃64;hadoop102 flume]$ sudo vim /etc/selinux/config

修改为&＃xff1a;

# This file controls the state of SELinux on the system.

# SELINUX&＃61; can take one of these three values:

#     enforcing – SELinux security policy is enforced.

#     permissive – SELinux prints warnings instead of enforcing.

#     disabled – No SELinux policy is loaded.

SELINUX&＃61;disabled

# SELINUXTYPE&＃61; can take one of these two values:

#     targeted – Targeted processes are protected,

#     mls – Multi Level Security protection.

SELINUXTYPE&＃61;targeted

尖叫提示&＃xff1a;selinux本次生效关闭必须重启&＃xff0c;如果此时不想重启&＃xff0c;可以临时生效之&＃xff1a;

[atguigu&＃64;hadoop102 flume]$ sudo setenforce 0

8&＃xff09;启动ganglia

[atguigu&＃64;hadoop102 flume]$ sudo service httpd start

[atguigu&＃64;hadoop102 flume]$ sudo service gmetad start

[atguigu&＃64;hadoop102 flume]$ sudo service gmond start

9&＃xff09;打开网页浏览ganglia页面

http://192.168.9.102/ganglia

尖叫提示&＃xff1a;如果完成以上操作依然出现权限不足错误&＃xff0c;请修改/var/lib/ganglia目录的权限&＃xff1a;

[atguigu&＃64;hadoop102 flume]$ sudo chmod -R 777 /var/lib/ganglia。
