yum install ganglia*

配置 Ganglia（仅指出必要配置部分）

编辑配置文件：

vim /etc/ganglia/gmetad.conf

data_source "solrcluster" 127.0.0.1 # 运行 gmod 机器的 IP
```  

```bash
vim /etc/ganglia/gmond.conf

cluster {
    name = "solrcluster"
    owner = "unspecified"
    latlong = "unspecified"
    url = "unspecified"
}
```  
 

```bash
vim /etc/httpd/conf.d/ganglia.conf

<Location /ganglia>
    Order deny,allow
    Allow from all
    Allow from 127.0.0.1
    Allow from ::1
    # Allow from .example.com
</Location>

配置 Solr 启动参数

必要参数配置：

# /home/solr/start-solr.sh
java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=3000 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=127.0.0.1 -jar start.jar

配置 JMXTrans

配置文件路径：/var/lib/jmxtrans/solr.json

注意： host 的 IP 地址必须与 -Djava.rmi.server.hostname=IP_OR_HOSTNAME 参数指定的 IP 相同

启动服务

注意： JMXTrans 要最后启动

/etc/init.d/httpd start
/etc/init.d/gmetad start
/etc/init.d/gmond start
/home/solr/start-solr.sh
/etc/init.d/jmxtrans start
