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 {      
  name = "hadoop201"
  owner = "nobody"
  latlong = "unspecified"
  url = "unspecified"
}

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：

# Gmetad-webfrontend version. Used to check for updates.#$conf['gweb_root'] = "/var/www/html/ganglia";
$conf['gweb_confdir'] = "/var/www/html/ganglia";

问题及解决方式

1. 编译rrdtool 错误 
   /.libs/librrd.so: undefined reference to xmlTextReaderValue@LIBXML2_2.4.30' 
./.libs/librrd.so: undefined reference toxmlTextReaderNodeType@LIBXML2_2.4.30’ 
   ./.libs/librrd.so: undefined reference to xmlStrdup@LIBXML2_2.4.30' 
./.libs/librrd.so: undefined reference toxmlTextReaderName@LIBXML2_2.4.30’ 
   ./.libs/librrd.so: undefined reference to xmlNewTextReaderFilename@LIBXML2_2.4.30'

   ./.libs/librrd.so: undefined reference to `xmlStrcasecmp@LIBXML2_2.4.30’

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
