Ganglia源码安装

太久没写博客了，突然心血来潮，记录下自己折腾了一个上午的ganglia安装流程。

安装:

tar -xz -f expat-2.1.0.tar.gz && cd expat-2.1.0 ./configure --prefix=/apps/svr/expat-2.1.0 make && make install tar -xz -f confuse-2.7.tar.gz && cd confuse-2.7 ./configure --prefix=/apps/svr/confuse-2.7 CFLAGS=-fPIC --disable-nls make && make install #如果系统是64位的还需要(编译ganglia时候需要用到该库)：cp -a /apps/svr/confuse-2.7/lib /apps/svr/confuse-2.7/lib64 tar -xz -f apr-1.6.2.tar.gz && cd apr-1.6.2 ./configure --prefix=/apps/svr/apr-1.6.2 make && make install #因为ganglia编译时候会去/apps/svr/apr-1.6.2/include下寻找库文件，所以需要做：cp -a /apps/svr/apr-1.6.2/include/apr-1/* /apps/svr/apr-1.6.2/include/ ,如果系统是64位的还需要:cp -a /apps/svr/apr-1.6.2/lib /apps/svr/apr-1.6.2/lib64 tar -xz -f pcre-8.32.tar.gz && cd pcre-8.32 ./configure --prefix=/apps/svr/pcre-8.32 make && make install tar -xz -f rrdtool-1.5.0.tar.gz && cd rrdtool-1.5.0 ./configure --prefix=/apps/svr/rrdtool-1.5.0 --disable-tcl make && make install tar -xz -f httpd-2.2.34.tar.gz && cd httpd-2.2.34 ./configure --prefix=/apps/svr/httpd-2.2.34 --enable-so --enable-mods-shared=most make && make install #复制源码包(httpd-2.2.34/build/httpd.init)启动脚本去/apps/sh,修改：httpd=${HTTPD-/apps/svr/httpd-2.2.34/bin/httpd} pidfile=${PIDFILE-/apps/run/httpd/httpd.pid} CONFFILE=/apps/svr/httpd-2.2.34/conf/httpd.conf 修改/apps/svr/httpd-2.2.34/conf/httpd.conf User apps Group apps #添加index.php

直接读取监控数据：除 了使用ganglia内置的网页页面外，也可以自行得到xml文件去进行自己的分析。通常需要自己编写一个脚本来完成该任务。通过直接telnet gmond或者gmetad的tcp服务监听端口，可以直接得到xml文件，然后我们就可以对该xml文件进行需要的处理了。在单播模式下，应该 telnet那个gmond的中央节点，登录该节点才能得到集群内所有节点的信息，否则只能得到单独节点的信息。
