- 如果安装过程中还有其他包缺失。可以执行如下命令，从本地源安装
- yum -y install apr-devel apr-util check-devel cairo-devel pango-devel libxml2-devel rpmbuild glib2-devel dbus-devel freetype-devel fontconfig-devel gcc-c++ expat-devel python-devel libXrender-devel
ganglia配置
gMetad配置
在ganglia安装目录执行如下操作
配置gMetad.conf
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
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
Metad: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
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
