接前面的，安装还是相对比较简单，遇到最多的问题也就是缺少某些包，这个少什么装什么就可以了
下面看一下配置服务端：
下载ganglia-web源码包,
#wget http://sourceforge.net/projects/ganglia/files/ganglia-web/3.5.12/ganglia-web-3.5.12.tar.gz
#tar -zxvf ganglia-web-3.5.12.tar.gz
#mkdir /var/www/html/ganglia
# pwd
/root/ganglia-web-3.5.12
#cp -r /root/ganglia-web-3.5.12/* /var/www/html/ganglia/
chown nobody:nobody /var/www/html/ganglia/
修改conf.php
#cp conf_default.php conf.php
#more conf.php
$conf['gweb_confdir'] = "/var/www/html/ganglia"; #修改和之前位置一致的路径
$conf['gmetad_root'] = "/var/lib/ganglia";
$conf['rrds'] = "${conf['gmetad_root']}/rrds";
$conf['dwoo_compiled_dir'] = "${conf['gmetad_root']}/dwoo/compiled";
$conf['dwoo_cache_dir'] = "${conf['gmetad_root']}/dwoo/cache"; #修改为个接下来创建的目录一致的路径
$conf['rrdtool'] = "/usr/bin/rrdtool";
添加相关服务:(gmetad和gmond)
[root@db-192-168-1-34 /]# cp /root/ganglia-3.6.0/gmetad/gmetad.init /etc/init.d/gmetad
[root@db-192-168-1-34 /]# cp -f /usr/local/ganglia/sbin/gmetad /usr/sbin/gmetad
[root@db-192-168-1-34 /]# chkconfig --add gmetad
[root@db-192-168-1-34 /]# service gmetad start
Starting GANGLIA gmetad: [ OK ]
[root@db-192-168-1-34 /]# cp /root/ganglia-3.6.0/gmond/gmond.init /etc/rc.d/init.d/gmond
[root@db-192-168-1-34 /]# cp -f /usr/local/ganglia/sbin/gmond /usr/sbin/gmond
[root@db-192-168-1-34 /]# chkconfig --add gmond
[root@db-192-168-1-34 /]# service gmond start
Starting GANGLIA gmond: Configuration file '/etc/ganglia/gmond.conf' not found.
[ OK ]
上面提示没有找到gmond的配置文件，那么手动生成一个
[root@db-192-168-1-34 /]# gmond -t |tee /etc/ganglia/gmond.conf
[root@db-192-168-1-34 /]# service gmond restart
Shutting down GANGLIA gmond: [ OK ]
Starting GANGLIA gmond: [ OK ]
修改gmond.conf
[root@db-192-168-1-34 bin]# more /etc/ganglia/gmond.conf
/* This configuration is as close to 2.5.x default behavior as possible
The values closely match ./gmond/metric.h definitions in 2.5.x */
globals {
daemonize = yes
setuid = yes
user = nobody
debug_level = 0
max_udp_msg_len = 1472
mute = no
deaf = no
allow_extra_data = yes
host_dmax = 86400 /*secs. Expires (removes from web interface) hosts in 1 day */
host_tmax = 20 /*secs */
cleanup_threshold = 300 /*secs */
gexec = no
# By default gmond will use reverse DNS resolution when displaying your hostname
# Uncommeting following value will override that value.
# override_hostname = "mywebserver.domain.com"
# If you are not using multicast this value should be set to something other than 0.
# Otherwise if you restart aggregator gmond you will get empty graphs. 60 seconds is reasonable
send_metadata_interval = 0 /*secs */
}
/*
* The cluster attributes specified will be used as part of the <CLUSTER>
* tag that will wrap all hosts collected by this instance.
*/
cluster {
name = "skycluster"
owner = "nobody"
latlong = "unspecified"
url = "unspecified"
}
这里我只修改标红的即可，修改完后记得重启服务service gmond restart
修改 /etc/ganglia/gmetad.conf配置文件
data_source "skycluster" 192.168.1.34 其他都用了默认的配置
#service gmetad restart
创建rrd存放数据的目录以及dwoo目录并修改属性
mkdir -p /var/lib/ganglia/rrds
chown nobody:nobody /var/lib/ganglia/rrds
mkdir -p /var/lib/ganglia/dwoo/cache
mkdir -p /var/lib/ganglia/dwoo/compiled
chown nobody:nobody /var/lib/ganglia/dwoo/cache
chown nobody:nobody /var/lib/ganglia/dwoo/compiled
到这里差不多就配置完成了
网页键入地址http://192.168.1.34/ganglia
提示报错：You don't have permission to access /ganglia on this server
查看apache相关配置
#cd /etc/httpd/conf.d/
# more ganglia.conf.bak
#
# Ganglia monitoring system php web frontend
#
Alias /ganglia /usr/share/ganglia
<Location /ganglia>
Order allow,deny
allow from all
# Allow from .example.com
</Location>
这里可以看到配置和我们的路径/var/www/html/ganglia/并不一致，于是我们不使用此配置
确保允许访问，这里我们配置Allow from all
# more /etc/httpd/conf/httpd.conf
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all
通过gstat测试是否输出数据
# gstat -a
