本人在centos7上安装ganglia，实测，没有成功，可能是哪里没做对，mark一下。后来过了几天莫名其妙的用yum安装又好了。

ganglia配置
gmetad配置
在ganglia安装目录执行如下操作
- cp -a gmetad/gmetad.init /etc/init.d/gmetad
- chkconfig –add gmetad
- chkconfig –level 345 gmetad on
- gmetad -t | tee /usr/local/etc/gmetad.conf
- mkdir -p /var/lib/ganglia/rrds
- chown nobody:nobody /var/lib/ganglia/rrds
配置gmetad.conf
1.修改gmetad.conf 中 data_source
data_source "hadoop201" hadoop201
gmond配置
- cp -a gmond/gmond.init /etc/init.d/gmond
- chkconfig –add gmond
- chkconfig –level 345 gmond on
- gmond -t | tee /usr/local/etc/gmond.conf
配置gmond.conf
修改 cluster中 name 为在gmetad.conf 中的data_source
cluster { </p><p> name = "hadoop201"</p><p> owner = "nobody"</p><p> latlong = "unspecified"</p><p> url = "unspecified"</p><p>}</p><p>
Ganglia-web环境部署
- tar xvzf ganglia-web-3.6.2.tar.gz -C /var/www/html/
- cd /var/www/html/
- mv ganglia-web-3.5.12 ganglia
- chmod -R 777 /var/www/html/ganglia
- cd /var/www/html/ganglia
- cp conf_default.php conf.php
- vim conf.php
conf.php中有些默认配置和以上设置不一样的需要进行修改：

ganglia编译必须依赖rrdtool，而rrdtool安装不同机器可能出现莫名的安装错误，此时如果机器可以连接网络可以使用 yum -y install rrdtool 方式安装，但此时安装后，编译ganglia时仍然无法找到rrdtool相应的库，此时可以采用如下方法,使ganglia编译安装成功：
下载rrdtool-1.4.8.tar.gz ，解压后，将rrdtool-1.4.8/src/.libs 中相应库拷贝到如下目录：
home/hadoop/为我本机rrdtool-1.4.8所在路径：
cp /home/hadoop/rrdtool-1.4.8/src/.libs/.so /usr/local/lib/
cp /home/hadoop/rrdtool-1.4.8/src/.libs/*.a /usr/local/lib/
cp /home/hadoop/rrdtool-1.4.8/src/.libs/*.la /usr/local/lib/
cp /home/hadoop/rrdtool-1.4.8/src/rrd*.h /usr/local/include
