两天的时间整理搭建了hadoop+ganalia监控系统
虚拟机3台 centos 6.5
192.168.24.192 h1 namenode gmond
192.168.24.190 h2 datanode ganalia监控 ganalia-web gmetad gmond
192.168.24.189 h2 datanode gmond
软件下载
confuse-2.7 http://www.nongnu.org/confuse/
http://sourceforge.net/projects/ganglia/files/?source=navbar
gmond
yum install gcc apr apr-devel libconfuse libconfuse-devel expat-devel pcre pcre-devel -y
如果需安装gmetad
yum install rrdtool rrdtool-devel -y
如果需安装gweb
yum install rsync -y
由于libconfuse库不能用yum安装，
tar –xzvf confuse-2.7.tar.gz
cd ./confuse-2.7
./configure CFLAGS=-fPIC -disable-nls
make
make install
安装ganglia(全部节点都要安装)
tar -xzvf ganglia-3.7.2.tar.gz
cd ganglia-3.7.2
./configure --prefix=/usr/local/ganglia --with-gmetad --enable-gexec --with-python=/usr/local --with-librrd=/usr/bin
make
make install
gmetad配置 （主节点配置）
进入ganglia安装文件
cd ganglia-3.6.0
cp ./gmetad/gmetad.init /etc/init.d/gmetad
chkconfig --add gmetad
vim /etc/init.d/gmetad
修改如下（find / =name 'gmetad'搜索之）：
GMETAD=/usr/local/ganglia/sbin/gmetad
mkdir -p /etc/ganglia
ln -s /usr/local/ganglia/etc/gmetad.conf /etc/ganglia/gmetad.conf
修改gmetad.conf配置文件
{每个data_source由3个字段组成 "名称" 指定轮询间隔(秒) 主机列表 }
节点分组
vim /usr/local/ganglia/etc/gmetad.conf
/////////////////////////////////////////////// #
data_source "hadoop_namenode_h1" 10 192.168.24.192:8649
data_source "hadoop_datanode" 10 192.168.24.190:8650 192.168.24.189:8650
gridname "MyGrid XF hadoop test"
xml_port 8651
interactive_port 8652
rrd_rootdir "/var/lib/ganglia/rrds"
case_sensitive_hostnames 0
//////////////////////////////////////////////
service gmetad restart (重启gmetad)
被监控节点安装ganglia
yum安装gmond：yum -y install ganglia-gmond
或以下编译方式（由于本人在centos6.5上编译安装ganglia-gmond后，出现无法启动客户端，提示未识别的标识符模块，未能解决，最后采用yum解决；centos6.6 6.7均可编译安装）
yum install gcc apr apr-devel libconfuse libconfuse-devel expat-devel pcre pcre-devel -y
libconfuse 无法yum，看上面
cd /data/tools/
tar -axvf ganglia-3.7.2.tar.gz
cd ganglia-3.7.2
./configure --prefix=/usr/local/ganglia --with-gmetad --enable-gexec --with-python=/usr/local --with-librrd=/usr/bin
make && make install
ganglia配置 所有节点
mkdir -p /etc/ganglia
cp gmond/gmond.init /etc/init.d/gmond
chkconfig --add gmond
vim /etc/init.d/gmond
修改如下（find / =name 'gmond'搜索之）：
GMOND=/usr/local/ganglia/sbin/gmond
节点使用 生成配置文件
mkdir /usr/local/ganglia/etc/
./gmond/gmond -t | tee /usr/local/ganglia/etc/gmond.conf
ln -s /usr/local/ganglia/etc/gmond.conf /etc/ganglia/gmond.conf
修改gmond.conf 分组，默认多播模式
vim /etc/ganglia/gmond.conf
send_metadata_interval = 30
cluster {
name = #对应gmetad中的data_source
...}
host {
location = "190-h2" #随意起个名字
}
udp_send_channel {
#mcast_join = 239.2.11.71 #默认多播，我这里使用的单播
port = 8650 #注意修改对应端口 gmetad配置文件的data_source
host = 192.168.24.189 #单播 gmetad配置文件的data_source
ttl = 1
}
udp_recv_channel {
#mcast_join = 239.2.11.71
port = 8650
#bind = 192.168.24.189 #本机ip
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
}
tcp_accept_channel {
port = 8650 #注意修改对应端口 gmetad配置文件的data_source
# If you want to gzip XML output
gzip_output = no
}
service gmond restart
------------------------------------------------------------------------
------------------------------------------------------------------------
节点分组 单播配置，可跨网段(多播默认配置即可)
ganglia配置文件中需要对应gmetad配置文件的data_source命名
udp_send_channel { #这段的host指向data_source命名后的配置地址即可实现单播
host = 192.168.24.189
------------------------------------------------------------------------
安装ganglia-web（仅主节点安装）
tar -zxvf ganglia-web-3.5.12.tar.gz
cd ganglia-web-3.5.12/
vim Makefile
GDESTDIR = /var/www/ganglia
APACHE_USER = apache # 与 /etc/php-fpm.d/www.conf 中user保持一致
make install
修改配置文件
mkdir -p /var/lib/ganglia/rrds
chown nobody:nobody /var/lib/ganglia/rrds
安装PHP
PHP5.3 XF
yum install php-fpm php-common php-devel php-mysqlnd php-mbstring php-mcrypt -y
PHP5.5
yum --enablerepo=remi,remi-php55 install php-fpm php-common php-devel php-mysqlnd php-mbstring php-mcrypt
service php-fpm start
装nginx-1.9.7
location ~ \.php$ {
root /var/www;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
cat /var/www/t.php
<?php
phpinfo();
?>
主配置文件 nginx.conf加入 include conf.d/*.conf;
vim /usr/local/nginx/conf/conf.d/ganglia.conf
location /ganglia {
root /var/www;
index index.html index.htm index.php;
}
