安装基本的php,curl,尽量装吧,相关的都安装好.

更新源

yum install wget gcc make rsync

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum makecache

安装依赖包

  yum install apr-devel
  

• zlib

  yum install zlib-devel
  

• libConfuse

  http://www.nongnu.org/confuse/
  
  yum install libconfuse-devel
  

• expat

  http://expat.sourceforge.net
  
  yum install expat-devel
  

• pcre

  yum install pcre-devel
  

• RRD

安装Ganglia

http://ganglia.info/

wget http://sourceforge.net/projects/ganglia/files/ganglia%20monitoring%20core/3.6.0/ganglia-3.6.0.tar.gz/download -O ~/ganglia-3.6.0.tar.gz

tar zxvf ganglia-3.6.0.tar.gz
cd ganglia-3.6.0

./configure --prefix=/usr/local/ganglia-3.6.0 --enable-gexec --enable-status --with-gmetad --with-librrd --with-libconfuse --with-zlib
make
make install

配置

设置软链接

ln -s /usr/local/ganglia-3.6.0/sbin/gmond /usr/bin/gmond
安装好后，声明Gmond配置文件，并修改：

gmond --default_config > /usr/local/ganglia-3.6.0/etc/gmond.conf

cluster {
    name = "ganglia.monitor"
    owner = "unspecified"
    latlong = "unspecified"
    url = "unspecified"
}

udp_send_channel {
    host = ganglia.monitor
    port = 8649
    ttl = 1
}

udp_recv_channel {
    port = 8649
}
tcp_accept_channel {
    port = 8649
}

 我们可以把Gmond添加到启动脚本

cp -f  ganglia-3.6.0/gmond/gmond.init  /etc/init.d/gmond 

vi /etc/init.d/gmond

GMOND=/usr/local/ganglia-3.6.0/sbin/gmond 

 服务器端安装配置

vi /usr/local/ganglia-3.6.0/etc/gmetad.conf 

setuid_username "nobody"
data_source "ganglia.monitor" localhost

设置RRD存储

mkdir -p /var/lib/ganglia/rrds
chown -R nobody:nobody /var/lib/ganglia/rrds

安装Web

yum install php-common php-cli php php-gd httpd  

下载
wget http://sourceforge.net/projects/ganglia/files/ganglia-web/3.5.12/ganglia-web-3.5.12.tar.gz/download -O ~/ganglia-web-3.5.12.tar.gz
tar zxvf ganglia-web-3.5.12.tar.gz 
cd ganglia-web-3.5.12

修改Makefile
vi Makefile 
# Location where gweb should be installed to (excluding conf, dwoo dirs).
GDESTDIR = /var/www/html/ganglia

# Location where default apache configuration should be installed to.
GCONFDIR = /etc/ganglia-web

# Gweb statedir (where conf dir and Dwoo templates dir are stored)
GWEB_STATEDIR = /var/lib/ganglia-web

# Gmetad rootdir (parent location of rrd folder)
GMETAD_ROOTDIR = /var/lib/ganglia

APACHE_USER = apache

安装
make install

防火墙规则设置
iptables -I INPUT 3 -p tcp -m tcp --dport 80 -j ACCEPT
iptables -I INPUT 3 -p udp -m udp --dport 8649 -j ACCEPT

service iptables save
service iptables restart

关闭selinux
vi /etc/selinux/config
SELINUX=disabled
setenforce 0

 单播模式的配置及防火墙设置的一点经验

设置多个data_source

data_source "ganglia.monitor1" localhost:6149

data_source "ganglia.monitor2" host1:6150

data_source "ganglia.monitor3" host1:6151

客户端配置:

cluster {
    name = "ganglia.monitor2"
    owner = "unspecified"
    latlong = "unspecified"
    url = "unspecified"
}

udp_send_channel {
    host = host1
    port = 8650
    ttl = 1
}

udp_recv_channel {
    port = 8650
}
tcp_accept_channel {
    port = 8650
}

根据个人经验,ganglia.monitor2小集群内的每台机器都要开放udp8650端口,同时,集群的主节点host1需要开发tcp8650端口;

其他方面,继续实践中.
