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';

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,拷贝后可以不用再编译将rrdtool：

进入rrdtool-1.4.8所在目录执行如下拷贝操作：

cp src/.libs/*.so* /usr/local/lib/

cp src/.libs/*.a /usr/local/lib/

cp src/.libs/*.la /usr/local/lib/

cp src/rrd*.h /usr/local/include

metad: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

解决方法

执行如下命令：

whereis libpcre.so.1
显示如下：
libpcre.so: /lib64/libpcre.so.0 /usr/local/lib/libpcre.so.1 /usr/local/lib/libpcre.so

然后建立连接：
ln -s /usr/local/lib/libpcre.so /lib64/libpcre.so.1

效果展示
