云监控 Ganglia 安装步骤（云端监控怎么安装）

Ganglia是一个监控服务器，集群的开源软件，能够用曲线图表现最近一个小时，最近一天，最近一周，最近一月，最近一年的服务器或者集群的cpu负载,内存,网络,硬盘等指标

Ganglia的强大在于：ganglia服务端能够通过一台客户端收集到同一个网段的所有客户端的数据，ganglia集群服务端能够通过一台服务端收集到它下属的所有客户端数据。这个体系设计表示一台服务器能够通过不同的分层能够管理上万台机器。这个功能是其他mrtg,nagios,cacti所不能比拟

1.相关环境

全部主机确认:

iptables关闭

SELinux disabled

2.部署规划

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

安装路径规划

3.代码获取

ganglia-web-3.5.10.tar.gz

httpd-2.2.23.tar.gz

php-5.4.10.tar.gz

4.前提依赖

4.1 主机环境检查(全部主机节点)

5.编译安装

5.1 安装ganglia (全部节点都要安装)

# tar -zxf ganglia-3.6.0.tar.gz

# cd ganglia-3.6.0

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

Copyright (c) 2005 University of California, Berkeley

Version: 3.6.0

Library: Release 3.6.0 0:0:0

Type "make" to compile.

# make && make install

5.2 安装ganglia-web (主节点安装)

# tar -zxf ganglia-web-3.5.10.tar.gz -C /export/home/ganglia/

# cd /export/home/ganglia/ganglia-web-3.5.10

# cp conf_default.php conf.php

vi conf.php 调整为如下内容

$conf['gweb_confdir'] = "/export/home/ganglia/ganglia-web-3.5.10";

$conf['gmetad_root'] = "/export/home/ganglia";

vi header.php

session_start();

ini_set('date.timezone','PRC'); --修改时区为本地时区

if (isset($_GET['date_only'])) {

$d = date("r");

echo $d;

exit(0);

}

配置临时目录

cd /export/home/ganglia/ganglia-web-3.5.10/dwoo

mkdir cache

chmod 777 cache

mkdir compiled

chmod 777 compiled

5.3 安装apache (主节点安装)

tar -zxf httpd-2.2.23.tar.gz

cd httpd-2.2.23

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

make && make install

5.4 安装php (主节点安装)

tar -zxf php-5.4.10.tar.gz

cd php-5.4.10

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

make && make install

5.5 使用apache发布ganglia-web (主节点安装)

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

....

Listen 80

....

odule dir_module>

DirectoryIndex index.html index.php

AddType application/x-httpd-php .php

Module>

....

# 在文件最后增加如下内容

# ganglia

Alias /ganglia "/export/home/ganglia/ganglia-web-3.5.10"

ectory "/export/home/ganglia/ganglia-web-3.5.10">

AuthType Basic

Options None

AllowOverride None

Order allow,deny

Allow from all

rectory>

启动httpd服务

/usr/local/apache2/bin/apachectl restart

6.配置Ganglia

6.1 配置gmetad (主节点配置)

cd ganglia-3.6.0

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

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

vi /etc/init.d/gmetad --修改如下内容

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

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

data_source "duangr-cluster" 10 duangr-1 duangr-2 duangr-3

xml_port 8651

interactive_port 8652

rrd_rootdir "/export/home/ganglia/rrds"

case_sensitive_hostnames 0

修改rrds数据目录所有者

chown -R nobody:nobody /export/home/ganglia/rrds

启动gmetad服务,并设为开机自动运行

service gmetad restart

chkconfig --add gmetad

6.2 配置gmond (全部节点配置)

cd ganglia-3.6.0

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

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

/etc/init.d/gmond --修改如下内容

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

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

cluster {

name = "duangr-cluster"

owner = "nobody"

latlong = "unspecified"

url = "unspecified"

}

复制python module到ganglia部署目录

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

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

安装程序ganglia-3.6.0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

若对默认提供的这些监控脚本不太关心,可以跳过下面这步:

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

启动gmond服务,并设为开机自动运行

service gmond restart

chkconfig --add gmond
