Ganglia安装

1.前期准备

1.1.节点准备

修改主机名、ip、iptables关闭；时间同步

关闭防火墙

service iptables stop

查看防火墙开机启动状态

chkconfig iptables –list

关闭防火墙的开机启动

chkconfig iptables off

1.2.软件准备

ganglia-3.7.1.tar.gz、ganglia-web-3.7.0.tar.gz 地址：http://ganglia.info/?page_id=66

confuse-2.7.tar.gz 地址：http://www.nongnu.org/confuse/

Python-2.7.10.tgz 地址：https://www.python.org/downloads/release/python-2710/

httpd-2.2.31.tar.gz 地址：http://httpd.apache.org/download

php-5.6.12.tar.gz 地址：http://php.net/downloads.php

2.集群规划

2.1

1主 2从

2.2.软件规划

Ganglia监控服务的主节点需要安装:ganglia、ganglia-web、php、apache

Ganglia被监控从节点需要安装:ganglia

2.3.安装路径

ganglia-core安装路径 /usr/local/ganglia

php安装路径 /usr/local/php

apache安装路径 /usr/local/apache2

ganglia-web安装路径 /opt/ganglia/ganglia-web

rrds数据路径 /opt/ganglia/rrds

3.安装框架

3.1.检查依赖[或者安装过程中发现缺少再安装]

rpm -q gcc glibc glibc-common rrdtool rrdtool-devel expat expat-devel pcre pcre-devel dejavu-lgc-sans-mono-fonts dejavu-sans-mono-fonts zlib-devel pcre pcre-devel apr apr-devel apr-util apr-util-devel

yum安装：

yum install -y gcc glibc glibc-common rrdtool rrdtool-devel expat expat-devel dejavu-lgc-sans-mono-fonts dejavu-sans-mono-fonts zlib-devel pcre pcre-devel apr apr-devel apr-util apr-util-devel perl libxml2 libxml2-devel

3.2.安装ganglia

将要安装的源文件传到一个节点的/opt/src下

cd /opt/src

3.2.1.confuse

//libconfuse 是一个用C实现配置文件解析器库

tar zvxf confuse-2.7.tar.gz

cd confuse-2.7

./configure CFLAGS=-fPIC –disable-nls

//-fPIC 作用于编译阶段，告诉编译器产生与位置无关代码(Position-Independent Code)则产生的代码中，没有绝对地址，全部使用相对地址，故而代码可以被加载器加载到内存的任意位置，都可以正确的执行。这正是共享库所要求的，共享库被加载时，在内存的位置不是固定的。

//–disable-nls:禁止对国际化支持

make && make install

3.2.2.python

// ganglia-gmond-modules-python

//很慢

python[默认的python.so路径/usr/lib64/]

cd /opt/src

tar -zvxf Python-2.7.10.tgz

cd /opt/src/Python-2.7.10

./configure –prefix=/usr/local –enable-shared

make && make install

//安装后libpython2.7.so在/usr/local/lib下

配置共享库

vi /etc/ld.so.conf

– 增加如下内容#python.so所在位置

/usr/local/lib



ldconfig

//ldconfig 命令的用途,主要是在默认搜寻目录(/lib和/usr/lib)以及动态库配置文件/etc/ld.so.conf内所列的目录下,搜索出可共享的动态链接库(格式如前介绍,lib*.so*),

检查是否生效

ldconfig -v |grep “libpython2.7.so”

3.2.3.ganglia

3.2.3.1.安装

cd /opt/src

tar zvxf ganglia-3.7.1.tar.gz

cd ganglia-3.7.1

./configure –prefix=/usr/local/ganglia –with-gmetad –enable-gexec –with-python=/usr/local

make && make install

3.2.3.2.配置gmond（所有节点）

cd /opt/src/ganglia-3.7.1

//初始化gmond配置文件

./gmond/gmond -t > /usr/local/ganglia/etc/gmond.conf

vi /usr/local/ganglia/etc/gmond.conf – 修改如下内容

cluster {
name = "cloud-cluster"
owner = "nobody"
latlong = "unspecified"
url = "unspecified"
}

udp_send_channel {
#bind_hostname = yes # Highly recommended, soon to be default.
# This option tells gmond to use a source address
# that resolves to the machine's hostname.  Without
# this, the metrics may appear to come from any
# interface and the DNS names associated with
# those IPs will be used to create the RRDs.
mcast_join = 239.2.11.71
port = 8649
ttl = 1
}
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8649
bind = 239.2.11.71
retry_bind = true
# Size of the UDP buffer. If you are handling lots of metrics you really
# should bump it up to e.g. 10MB or even higher.
# buffer = 10485760
}

###################################添加python指标Begin

复制python module到ganglia部署目录

mkdir /usr/local/ganglia/lib64/ganglia/python_modules

cd /opt/src/ganglia-3.7.1

cp ./gmond/python_modules//.py /usr/local/ganglia/lib64/ganglia/python_modules

安装程序ganglia-3.7.1默认提供了一些python module的配置文件,只需要部署到 /usr/local/ganglia/etc/conf.d 目录下面即可生效

cp ./gmond/python_modules/conf.d/*.pyconf /usr/local/ganglia/etc/conf.d

###################################添加python指标End

//添加开机启动

cd /opt/src/ganglia-3.7.1

cp ./gmond/gmond.init /etc/init.d/gmond

cp /usr/local/ganglia/etc/gmond.conf /etc/ganglia/

vi /etc/init.d/gmond –修改如下内容

GMOND=/usr/local/ganglia/sbin/gmond



//添加开机启动

chkconfig –add gmond

开启服务：

service gmond start/restart

在gmond机器上测试

telnet localhost 8649

3.2.3.3.配置gmetad(主节点)

cd /opt/src/ganglia-3.7.1

vi /usr/local/ganglia/etc/gmetad.conf – 修改如下内容

##如果此文件没有 cp ./gmetad/gmetad.conf /usr/local/ganglia/etc/

－－从第一台响应主机开始收集状态数据

data_source “cloud-cluster” 10 fuze246 fuze247 fuze248

gridname “cloud-grid”

－－gmetad侦听端口

xml_port 8651

－－gmetad交互式侦听端口

interactive_port 8652

rrd_rootdir “/opt/ganglia/rrds”

case_sensitive_hostnames 0

创建和修改rrds数据目录所有者

mkdir -p /opt/ganglia/rrds

chown -R nobody:nobody /opt/ganglia/rrds

启动gmetad服务

service gmetad restart

设置开机启动

cd /opt/src/ganglia-3.7.1

cp ./gmetad/gmetad.init /etc/init.d/

cp /usr/local/ganglia/etc/gmetad.conf /etc/ganglia/

vi /etc/init.d/gmetad 修改如下内容

GMETAD=/usr/local/ganglia/sbin/gmetad



chkconfig –add gmetad

在gmetad机器上测试

telnet localhost 8651

3.2.3.4.安装ganglia-web (主节点)

3.2.3.4.1.安装apache

cd /opt/src

tar zvxf httpd-2.2.31.tar.gz

cd httpd-2.2.31

./configure –prefix=/usr/local/apache2

make && make install

3.2.3.4.2.安装php(安装很慢)

#vi /usr/local/apache2/bin/apxs

#有的版本要将第一行改为perl位置即：#!/usr/bin/perl -w

cd /opt/src

tar zvxf php-5.6.12.tar.gz

cd php-5.6.12

./configure –prefix=/usr/local/php –with-apxs2=/usr/local/apache2/bin/apxs

make && make install

3.2.3.4.3.ganglia-web

cd /opt/src

tar zvxf ganglia-web-3.7.0.tar.gz -C /opt/ganglia

mv /opt/ganglia/ganglia-web-3.7.0 /opt/ganglia/ganglia-web

cd /opt/ganglia/ganglia-web

cp conf_default.php conf.php

vi conf.php

$conf['gweb_confdir'] = "/opt/ganglia/ganglia-web";
# Where gmetad stores the rrd archives.
$conf['gmetad_root'] = "/opt/ganglia";
$conf['rrds'] = "${conf['gmetad_root']}/rrds";

vi header.php

<?php
session_start();
ini_set('date.timezone','PRC');      --修改时区为本地时区
# If you want to grab data from a different ganglia source specify it here.
# Although, it would be strange to alter the IP since the Round-Robin
# databases need to be local to be read.
$conf['ganglia_ip'] = "127.0.0.1";
$conf['ganglia_port'] = 8652;

配置临时目录:[dwoo是php的模版引擎]

cd /opt/ganglia/ganglia-web/dwoo

mkdir cache compiled

chmod 777 cache compiled

配置服务器设置

vi /usr/local/apache2/conf/httpd.conf

....
Listen 80
....

<IfModule dir_module>
DirectoryIndex index.html index.php
AddType application/x-httpd-php .php
</IfModule>
