\[color=green\]\[size=large\]Ganglia的安装，可以使用yum和rpm来进行，对于刚装的系统需要分别执行以下几个命令，来完成初始化安装：  
  
\[/size\]\[/color\]

yum install –y wget 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 rrdtool*
    
    rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
    rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
     rpm -ivh http://github.com/downloads/jmxtrans/jmxtrans/jmxtrans-20121016.145842.6a28c97fbb-0.noarch.rpm
    
    yum install ganglia*

\[color=green\]\[size=large\]安装完成后，即可配置。  
  
1， 修改ganglia的conf配置，  
修改 /etc/ganglia/gmetad.conf，数据源的配置  
data\_source "solr cluster" 127.0.0.1  
集群IP，可以设置多个IP地址，也可以设置多个数据源。  
  
  
2，修改 /etc/ganglia/gmond.conf的配置，把name对应起来  
cluster \{  
name = "solr cluster"  
owner = "unspecified"  
latlong = "unspecified"  
url = "unspecified"  
\}  
3，修改/etc/httpd/conf.d/ganglia.conf，Apache的配置，不拦截ganglia的数据包  
Alias /ganglia /usr/share/ganglia  
  
<Location /ganglia>  
Order deny,allow  
Allow from all  
Allow from 192.168.46.21  
Allow from ::1  
\# Allow from .example.com  
</Location>  
  
\[/size\]\[/color\]  
\[color=olive\]\[size=large\]4，cd /var/lib/jmxtrans  
配置jmxtrans  
添加solr.json  
  
solr.json的配置如下：  
\[/size\]\[/color\]

{
       
        "servers" : [
        {
       
            "host" : "192.168.46.23",

                         "port" : "8649"
                     }
                 }]
            },

                     }
                 }]
            },
            {

                         "port" : "8649"
                     }
                 }]
            },
            {
       
                "obj" : "solr/collection1:type=queryResultCache,id=org.apache.solr.search.LRUCache",
                "resultAlias": "solr23.queryCache",

                    "settings" : {
       
                        "groupName" : "Solr-JVM",
                        "host" : "239.2.11.71",
                        "port" : "8649"
                    }
                }]
            },
            {
       
                "obj" : "solr/collection1:type=searcher,id=org.apache.solr.search.SolrIndexSearcher",
               "resultAlias": "solr23.searcher",

                "outputWriters" : [

                    "@class" : "com.googlecode.jmxtrans.model.output.GangliaWriter",
                    "settings" : {
       
                        "groupName" : "Solr-JVM",
                        "host" : "239.2.11.71",
                        "port" : "8649"
                    }
                }]
            }]
        }]
    }

\[color=olive\]\[size=large\]配置完成后，需要依次，启动如下服务：\[/size\]  
\[/color\]

service httpd start  //启动apache服务
    /etc/init.d/gmetad start   //启动绘图服务
    /etc/init.d/gmond start   //启动数据收集服务
    这个放在solr前执行  jmx
    /etc/init.d/jmxtrans start  //启动jmx
    /home/solr/start-solr.sh  //启动solr

\[color=olive\]\[size=large\]注意，solr启动的jetty的jar需要加上JMX的监控参数，内容如下：\[/size\]\[/color\]

java -Djava.rmi.server.hostname=192.168.46.23    -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=3000 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -jar start.jar

\[color=olive\]\[size=large\]最后需要注意一点，为了防止访问apache服务出错，  
如果出现：There was an error collecting ganglia data (127.0.0.1:8652): fsockopen error: Permission denied . 错误，我们需要进行以下的设置：\[/size\]\[/color\]

（1）：临时可以使用命令setenforce 0来关闭selinux而不需要重启，刷新页面，即可访问！
    （2）:永久的使用，需要关闭selinux：vi /etc/selinux/config，把SELINUX=enforcing改成SELINUX=disable；需要重启机器。

\[color=olive\]\[size=large\]一切完成后，我们就是访问我们本机的ip地址，看到的界面如下所示：\[/size\]\[/color\]

\[color=green\]\[size=large\]到此，我们的单机监控solr的demo，就部署成功了，以同样的方式，我们还可以对hadoop进行监控，另外我们还可以配置多个datasource来监控多个应用。\[/size\]\[/color\]
