Ganglia的安装与部署

1）安装httpd服务与php

[atguigu@hadoop102 flume]$ sudo yum -y install httpd php

2）安装其他依赖

[atguigu@hadoop102 flume]$ sudo yum -y install rrdtool perl-rrdtool rrdtool-devel

[atguigu@hadoop102 flume]$ sudo yum -y install apr-devel

3）安装ganglia

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

[atguigu@hadoop102 flume]$ sudo yum -y install ganglia-gmetad

[atguigu@hadoop102 flume]$ sudo yum -y install ganglia-web

[atguigu@hadoop102 flume]$ sudo yum install -y ganglia-gmond

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

[atguigu@hadoop102 flume]$ sudo vim /etc/httpd/conf.d/ganglia.conf

修改为红颜色的配置：

# Ganglia monitoring system php web frontend

Alias /ganglia /usr/share/ganglia

<Location /ganglia>

Order deny,allow

#Deny from all

Allow from all

# Allow from 127.0.0.1

# Allow from ::1

# Allow from .example.com

</Location>

5）修改配置文件/etc/ganglia/gmetad.conf

[atguigu@hadoop102 flume]$ sudo vim /etc/ganglia/gmetad.conf

修改为：

data_source “hadoop102” 192.168.9.102

6）修改配置文件/etc/ganglia/gmond.conf

[atguigu@hadoop102 flume]$ 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

host = 192.168.9.102

port = 8649

ttl = 1

}

udp_recv_channel {

# mcast_join = 239.2.11.71

port = 8649

bind = 192.168.9.102

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/etc/selinux/config

[atguigu@hadoop102 flume]$ sudo vim /etc/selinux/config

修改为：

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

# SELINUX= 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=disabled

# SELINUXTYPE= can take one of these two values:

# targeted – Targeted processes are protected,

# mls – Multi Level Security protection.

SELINUXTYPE=targeted

尖叫提示：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：

[atguigu@hadoop102 flume]$ sudo setenforce 0

8）启动ganglia

[atguigu@hadoop102 flume]$ sudo service httpd start

[atguigu@hadoop102 flume]$ sudo service gmetad start

[atguigu@hadoop102 flume]$ sudo service gmond start

9）打开网页浏览ganglia页面

http://192.168.9.102/ganglia

尖叫提示：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：

[atguigu@hadoop102 flume]$ sudo chmod -R 777 /var/lib/ganglia
