ganglia配置

gmetad配置

在ganglia安装目录履行以下操作

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.修正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

修正 cluster中 name 为在gmetad.conf 中的data_source

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

Ganglia-web环境安排

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中有些默许配置和以上设置不一样的须要进行修正：

# 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";

问题及解决方法

编译rrdtool 毛病

ganglia编译必需依附rrdtool，而rrdtool安装不同机器可能涌现莫名的安装毛病，此时如果机器可以衔接网络可以应用 yum -y install rrdtool 方法安装，但此时安装后，编译ganglia时依然没法找到rrdtool相应的库，此时可以采取以下办法,使ganglia编译安装胜利：

下载rrdtool-1.4.8.tar.gz ，解压后，将rrdtool-1.4.8/src/.libs 中相应库拷贝到以下目录：

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
