1、实验环境
Centos6.4
2、安装rrdtool(注rrdtool-1.5.3不支持3.6.1)

#!/bin/sh
#安装confuse
tar zxf confuse-2.7. tar .gz
cd confuse-2.7

cd ..
#安装ganglia
tar zxf ganglia-3.6.1. tar .gz
cd ganglia-3.6.1
#server

cd gmetad
cp gmetad.conf /opt/modules/ganglia/etc/
cp gmetad.init /etc/init .d /gmetad

#我的服务器有两块网卡,eth1使用公网地址,eth2使用局域网地址,监控服务器和被监控服务器之间的通信通过局域网地址实现以减少公网网卡的负载,使用以下命令:(此IP可以在/etc/ganglia/gmond.conf中修改)
ip route add 239.2.11.71 dev eth2
service gmetad start
|
组播方式一定要使用ip route add 239.2.11.71 dev eth2如果只有一个网卡就指定那一个网卡就好
查看service gmetad status
报错gmetad dead but subsys locked
查看tail -f /var/log/messages发现需要增加目录以及修改gmetad.conf文件
(1)mkdir -p /var/lib/ganglia/rrds (此目录是配置rrd数据保存文件的路径,给web界面用的,这个是固定的,最好放在web文件夹下,并赋予正确的权限,默认即是这个路径,可以自行在/opt/modules/ganglia/etc/gmetad.conf中修改rrd_rootdir变量的值)
在安装完成httpd之后会有apache此用户,执行以下语句给rrds目录相应权限
chown -R apache:apache /var/lib/ganglia/rrds
(2)在gmetad.conf中修改setuid_username "apache" 这里需要username和rrd数据目录的owner一致
备注:
gmetad.conf修改内容如下:
data_source "MyCluster" 192.168.56.101:8649
gridname "MyGrid"
setuid_username "apache"
重新启动
service gmetad restart

#!/bin/sh
tar zxf confuse-2.7. tar .gz
cd confuse-2.7

tar zxf ganglia-3.6.1. tar .gz
cd ganglia-3.6.1
#server

cd gmond
. /gmond -t > /opt/modules/ganglia/etc/gmond .conf
cp gmond.init /etc/init .d /gmond
sed -i "s/^GMOND=\/usr\/sbin\/gmond/GMOND=\/opt\/modules\/ganglia\/sbin\/gmond/g" /etc/init .d /gmond
chkconfig --add gmond
ip route add 239.2.11.71 dev eth2
service gmond start
|
备注:gmond.conf修改如下(与gmetad.conf文件修改相对应):
cluster {
name = "MyCluster"
owner = "unspecified"
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
}
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8649
bind = 239.2.11.71
retry_bind = true
}
tcp_accept_channel {
port = 8649
# If you want to gzip XML output
gzip_output = no
}
以上都是组播方式的安装,如果使用单播的方式,需要修改gmond.conf文件
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
host = hostname
port = 8649
ttl = 1
}
udp_recv_channel {
#mcast_join = 239.2.11.71
port = 8649
#bind = 239.2.11.71
#retry_bind = true
}
