一、Ganglia安装

1.1 三台机器安装epel源

[usr@node01 flume]$ sudo yum install -y epel-release

[usr@node02 flume]$ sudo yum install -y epel-release

[usr@node03 flume]$ sudo yum install -y epel-release

1.2 在node01安装web,meta和monitor

[usr@node01 flume]$ sudo yum -y install ganglia-gmetad ganglia-web ganglia-gmond

1.3 在node02、node03安装monitor

[usr@node02 flume]$ sudo yum -y install ganglia-gmond
[usr@node03 flume]$ sudo yum -y install ganglia-gmond

1.4 node01修改配置文件/etc/httpd/conf.d/ganglia.conf

#
# 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
  Require all granted

1.5 node01修改配置文件/etc/ganglia/gmetad.conf

data_source "node01" node01 #第44行

1.6 node01,node02,node03上修改/etc/ganglia/gmond.conf

cluster {
  name = "node01" 
  owner = "unspecified"
  latlong = "unspecified"
  url = "unspecified"
}


host {
  location = "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 = node01        
  ttl = 1
}


udp_recv_channel {
  #mcast_join = 239.2.11.71 
  port = 8649
  bind = 0.0.0.0
  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
}

1.7 修改配置文件/etc/selinux/config

# 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

1.8 三台机器各自启动服务

[usr@node01 flume]$ sudo systemctl start httpd
[usr@node01 flume]$ sudo systemctl start gmetad
[usr@node01 flume]$ sudo systemctl start gmond
[usr@node02 flume]$ sudo systemctl start gmond
[usr@node03 flume]$ sudo systemctl start gmond

1.9 打开监控页面

http://node01/ganglia

在红框处进行数据源选择，可以看到选择自己关注的机器进行查看。

二、功能测试

2.1 Flume conf编写

#Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = node03
a1.sources.r1.port = 44444

# Describe the sink
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

2.2 启动服务

[usr@node03 flume]# bin/flume-ng agent --conf conf/ --name a1 --conf-file job/flume-netcat-logger.conf -Dflume.root.logger=INFO,console -Dflume.monitoring.type=ganglia -Dflume.monitoring.hosts=node01:8649

2.3 启动netcat发送数据

[usr@node03flume]$ nc node03 44444
