ganglia安装配置.docx

ganglia安装配置一、 基本环境apache+php+mysqlyum install httpd httpd-devel php*二、 安装ganglia1.ganglia相关依赖包1. yum install rrdtool rrdtool-devel2. libconfuse：rpm安装：官方网站下载失败，下载了版本稍旧一点rpm包：/libconfuse/wget /libconfuse/libconfuse-2.6-2.el5.rf.x86_64.rpmwget /libconfuse/libconfuse-devel-2.6-2.el5.rf.x86_64.rpmrpm -ivh libconfuse-*源码安装：wget /download/confuse/confuse-2.7.tar.gztar zxvf confuse-2.7.tar.gzcd confuse-2.7./configure CFLAGS=-fPIC -disable-nls make & make install调整lib库的位置：echo /usr/local/lib /etc/ld.so.conf.d/libconfuse.confldconfig -v3. yum install pcre*4. yum install expat*5. 其他依赖yum install 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 make*2.安装ganglia管理端（gmetad）wget /projects/ganglia/files/ganglia%20monitoring%20core/3.5.0/ganglia-3.5.0.tar.gz/downloadtar zxvf ganglia-3.5.0.tar.gzcd ganglia-3.5.0./configure -prefix=/usr/local/ganglia -with-librrd -with-libapr -with-libexpat -with-libconfuse -with-gmetad -enable-gexec -enable-statusmakemake install为rrdtool创建数据存放目录mkdir -p /var/lib/ganglia/rrdschown -R nobody:nobody /var/lib/ganglia/rrds将gmetad添加到系统服务cp ganglia解压目录gmetad/gmetad.init /etc/init.d/gmetad将gmetad命令加入到/usr/sbin/目录cp /usr/local/ganglia/sbin/gmetad /usr/sbin/gmetad给 chkconfig托管chkconfig -add gmetad开启gmetad服务service gmetad startStarting GANGLIA gmetad: OK 见到OK字样说明启动成功。3. 安装ganglia节点（gmond）ps：主控端也需要安装依赖：yum install prce* expat* apr-devel apr-util check-devel cairo-devel pango-devel libxml2-devel rpmbuild glib2-devel dbus-devel freetype-devel fontconfig-devel gcc-c+ python-devel libXrender-devel安装libconfuserpm安装：官方网站下载失败，下载了版本稍旧一点rpm包：/libconfuse/wget /libconfuse/libconfuse-2.6-2.el5.rf.x86_64.rpmwget /libconfuse/libconfuse-devel-2.6-2.el5.rf.x86_64.rpmrpm -ivh libconfuse-*wget /projects/ganglia/files/ganglia%20monitoring%20core/3.5.0/ganglia-3.5.0.tar.gz/download（1） 解压同gmetad（2） ./configure -prefix=/usr/local/ganglia -with-librrd -with-libapr -with-libexpat -with-libconfuse -enable-gexec -enable-status -sysconfdir=/etc/ganglia ./configure -prefix=/usr/local/ganglia -sysconfdir=/etc/ganglia（3） make & make install（4） 将gmond加入系统服务ganglia解压目录cp gmond/gmond.init /etc/init.d/gmond（5） 将gmond命令加入到/usr/sbin/目录cp /usr/local/ganglia/sbin/gmond /usr/sbin/（9） 生成gmond的默认配置文件mkdir /etc/ganglia/usr/local/ganglia/sbin/gmond -t |tee /etc/ganglia/gmond.conf（10） 将gmond给 chkconfig托管chkconfig -add gmond（11） 修改gmond配置文件/etc/ganglia/gmond.confcluster name = test clusterowner = nobodylatlong = unspecifiedurl = unspecified（12） 开启gmond服务service gmond startStarting GANGLIA gmetad: OK （6） 见到OK字样说明启动成功。4. 安装ganglia web页面4.2. 构建web服务器wget /projects/ganglia/files/ganglia-web/3.5.4/ganglia-web-3.5.4.tar.gz/downloadtar -xf ganglia-web-3.5.4.tar.gzcp -r ganglia-web-3.5.4 /apache：wwwroot/gangliacd /apache：wwwroot/gangliavim Makefile，修改参数GDESTDIR和APACHE_USER，然后执行make install进行安装：GDESTDIR=/usr/local/apache2/htdocs/gangliaAPACHE_USER=daemonmake installcp conf_default.php conf.phpvim conf.php，修改如下参数：$confgmetad_root = /var/lib/ganglia;$confrrds = $confgmetad_root/rrds;$confrrdtool = /usr/local/bin/rrdtool;$confexternal_location = http:/SERVER:10000/ganglia; /把SERVER替换成自己的g$confcase_sensitive_hostnames = false;禁用 SELinuxsetenforce 0启动并访问：service gmetad startservice gmond starthttp:/SERVER/ganglia/ /把SERVER替换成自己的ganglia服务器IP三. 集群式部署集群的部署依靠配置文件：vim /usr/local/ganglia/etc/gmetad.conf这里需要配置的是集群名称和server端地址data_source my cluster localhost? /etc/ganglia/gmond.conf这里需要配置cluster下的name和owner属性与gmetad端一致cluster name = my clusterowner = nobodylatlong = unspecifiedurl = unspecified? 如果修改owner，同时也要修改Rrdtool的数据文件目录的owner：chown -R nobody:nobody /var/lib/ganglia/rrds四添加apache监控插件（客户端）1.下载插件插件下载：/hirose31/ganglia-pymodule_apache_statusgit clone git://hirose31/ganglia-pymodule_apache_status.git apache_statuscp apache_status/conf.d/apache_status.conf /etc/ganglia/conf.d/cp -R apache_status/python_modules /etc/ganglia/2.修改apache_status地址vim /etc/ganglia/conf.d/apache_status.confmodules module name = apache_status language = python param url value = 42/server-status?auto #指向本机ip。 param virtual_host value = health 3.修改modpython.conf配置vim /etc/ganglia/conf.d/modpython.confmodules module name = python_module path = modpython.so params = /etc/ganglia/python_modules#指向上面拷贝到/etc/ganglia/下的python_modules目录 4.重启service gmond restart5.效果如下点击某个节点的详细监控信息页面：6.集群apache监控如果需要看整个集群的监控画面，则需要做一些配置，如下：修改/var/www/html/ganglia/conf.php，找到 $optional_graphs，去掉注释，修改为 $optional_graphs = array( apache)，保存，刷新监控页面即可看到监控图。五.安装过程中遇到的问题1 安装rrdtool过程中提示pkg-config错误一般是库没有装全，记得要安装dev库2 安装ganglia过程中找不到confuse，expat，apr等库如果是64位机，ganglia会在依赖库的lib64目录下去查找文件，所以需要将lib目录下文件拷贝到lib64目录下3 gmetad启动失败：查看gmetad状态：service gmetad statusgmetad dead but subsys locked在gmetad.conf中修改了用户setuid_username root 这里需要username和rrd数据目录的owner一致4 gmond启动失败：查看gmond状态：service gmond statusgmond dead but subsys locked可能是没有配置网关或者cluster的owner配置有问题5 访问网页保错：Ganglia cannot find a data source. Is gmond running?There was an error collecting ganglia data XML error : Invalid document现象是页面只有一行错误信息解决办法是修改conf.php中的$ganglia_ip = ;这里不能使用
