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:
<pre name="code" class="java">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* </pre> 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 &lt;Location /ganglia&gt; Order deny,allow Allow from all Allow from 192.168.46.21 Allow from ::1 # Allow from .example.com &lt;/Location&gt; 4,cd /var/lib/jmxtrans 配置jmxtrans 添加solr.json solr.json的配置如下: <pre name="code" class="java">{ "servers" : [ { "host" : "192.168.46.23", "alias" : "solr23", "port" : "3000", "queries" : [ { "obj" : "java.lang:type=Memory", "resultAlias": "solr23.heap", "attr" : [ "HeapMemoryUsage", "NonHeapMemoryUsage" ], "outputWriters" : [ { "@class" : "com.googlecode.jmxtrans.model.output.GangliaWriter", "settings" : { "groupName" : "Solr-JVM", "host" : "239.2.11.71", "port" : "8649" } }] }, { "obj" : "java.lang:name=CMS Old Gen,type=MemoryPool", "resultAlias": "solr23.cmsoldgen", "attr" : [ "Usage" ], "outputWriters" : [ { "@class" : "com.googlecode.jmxtrans.model.output.GangliaWriter", "settings" : { "groupName" : "Solr-JVM", "host" : "239.2.11.71", "port" : "8649" } }] }, { "obj" : "java.lang:type=GarbageCollector,name=*", "resultAlias": "solr23.gc", "attr" : [ "CollectionCount", "CollectionTime" ], "outputWriters" : [ { "@class" : "com.googlecode.jmxtrans.model.output.GangliaWriter", "settings" : { "groupName" : "Solr-JVM", "host" : "239.2.11.71", "port" : "8649" } }] }, { "obj" : "java.lang:type=Threading", "resultAlias": "solr23.threads", "attr" : [ "DaemonThreadCount", "PeakThreadCount", "ThreadCount", "TotalStartedThreadCount" ], "outputWriters" : [ { "@class" : "com.googlecode.jmxtrans.model.output.GangliaWriter", "settings" : { "groupName" : "Solr-JVM", "host" : "239.2.11.71", "port" : "8649" } }] }, { "obj" : "solr/collection1:type=queryResultCache,id=org.apache.solr.search.LRUCache", "resultAlias": "solr23.queryCache", "attr" : [ "warmupTime","size","lookups","evictions","hits","hitratio","inserts","cumulative_lookups","cumulative_hits","cumulative_hits","cumulative_hitratio","cumulative_inserts","cumulative_evictions" ], "outputWriters" : [ { "@class" : "com.googlecode.jmxtrans.model.output.GangliaWriter", "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", "attr" : [ "maxDoc","numDocs","warmupTime" ], "outputWriters" : [ { "@class" : "com.googlecode.jmxtrans.model.output.GangliaWriter", "settings" : { "groupName" : "Solr-JVM", "host" : "239.2.11.71", "port" : "8649" } }] }] }] } </pre> 配置完成后,需要依次,启动如下服务: <pre name="code" class="java">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 </pre> 注意,solr启动的jetty的jar需要加上JMX的监控参数,内容如下: <pre name="code" class="java">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 </pre> 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: <pre name="code" class="java">(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。 </pre> 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: 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。 声明:ITeye文章版权属于作者,受法律保护。没有作者书面许可不得转载。
