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";include_once $conf['gweb_root'] . "/version.php";## 'readonly': No authentication is required.  All users may view all resources.  No edits are allowed.#  'enabled': Guest users may view public clusters.  Login is required to make changes.  #             An administrator must configure an authentication scheme and ACL rules.# 'disabled': Guest users may perform any actions, including edits.  No authentication is required.$conf['auth_system'] = 'readonly';## The name of the directory in "./templates" which contains the# templates that you want to use. Templates are like a skin for the# site that can alter its look and feel.#$conf['template_name'] = "default";## If you installed gmetad in a directory other than the default# make sure you change it here.## Where gmetad stores the rrd archives.$conf['gmetad_root'] = "/var/lib/ganglia";$conf['rrds'] = "${conf['gmetad_root']}/rrds";# Where Dwoo (PHP templating engine) store compiled templates$conf['dwoo_compiled_dir'] = "${conf['gweb_confdir']}/dwoo/compiled";$conf['dwoo_cache_dir'] = "${conf['gweb_confdir']}/dwoo/cache";# Where to store web-based configuration$conf['views_dir'] = $conf['gweb_confdir'] . '/conf';$conf['conf_dir'] = $conf['gweb_confdir'] . '/conf';

`问题及解决方式`

编译rrdtool 错误

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
