安裝Ganglia Web
cd /opt/soft
tar -zxvf ganglia-web-3.7.2.tar.gz
cd ganglia-web-3.7.2
vi Makefile
GDESTDIR = /var/www/ganglia
APACHE_USER = apache                    # 與 /etc/php-fpm.d/www.conf 中user保持一致

安裝rsync
 yum install nginx -y --downloadonly --downloaddir=/opt/soft/rsync rsync
 yum localinstall -y /opt/soft/rsync/*.rpm  
 make install


配置nginx訪問ganglia


Nginx新增ganglia檔案目錄訪問配置
 vi /etc/nginx/nginx.conf
location /ganglia {
   root   /var/www;
   index  index.html index.htm index.php;
}    

cd /var/www
chown -R apache:apache ganglia/


配置Ganglia Web

  cd /var/www/ganglia
  cp conf_default.php conf.php
  
 mkdir  /var/www/ganglia/dwoo/compiled
 mkdir /var/www/ganglia/dwoo/cache
  vi conf.php
##conf.php中有些預設配置和以上設定不一樣的需要進行修改：
============================================================================================
$conf['gweb_root'] = "/var/www/ganglia";
$conf['gweb_confdir'] = "/var/www/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";  ##如果不存在可以手動建立並注意許可權
$conf['dwoo_cache_dir'] = "${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';


# Where to find filter configuration files, if not set filtering
# will be disabled
#$conf['filter_dir'] = "${conf['gweb_confdir']}/filters";


# Leave this alone if rrdtool is installed in $conf['gmetad_root'],
# otherwise, change it if it is installed elsewhere (like /usr/bin)
$conf['rrdtool'] = "/usr/bin/rrdtool"   


    service gmond restart
    service gmetad restart
    service php-fpm restart
    service nginx restart

     chmod +666 /usr/local/ganglia/var/run

    //要讓這個使用者可以寫入：apache 有寫許可權即可。
    chmod +666 /var/www/ganglia/dwoo/compiled
    chmod +666 /var/www/ganglia/dwoo/cache

注意 服務的啟動 start 與restart的區別。

其他需要監控的要裝:

       5 監控端安裝gmond及gmeta

cd /opt/soft
tar zxf ganglia-3.7.2.tar.gz
  cd ganglia-3.7.2
 ./configure --prefix=/usr/local/ganglia  --enable-gexec #這裡要去掉--with-gmetad，只啟用gmond
 make && make install

測試是否成功：

1 gmond ：要用nc localhost 8649

2 gmetad：直接去看特定目錄下是否有即時生成的檔案 如預設位置：

/var/lib/ganglia/rrds/master
