Nagios监控LVS

1、在LVS上安装web和php服务
# yum install httpd php -y
2、在LVS上安装rrdtool工具
# wget  http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz
# tar zxvf rrdtool-1.4.7.tar.gz
# cd rrdtool-1.4.7
# ./configure --prefix=/usr/local/rrdtool
# make
# make install
# cd
# echo "/usr/local/rrdtool/lib"   >> /etc/ld.so.conf
# ldconfig -v
3、下载安装lvs-rrd
# wget http://tepedino.org/lvs-rrd/lvs-rrd-v0.7.tar.gz
# tar -zxvf lvs-rrd-v0.7.tar.gz
# mv lvs-rrd-v0.7 /var/www/html/lvs
# cd /var/www/html/lvs/
4、修改默认配置，主要是些命令的路径指向
# vim lvs.rrd.update
......
    RRDTOOL="/usr/local/rrdtool/bin/rrdtool"
    IPVSADM="/sbin/ipvsadm"
    WORKDIR="/var/www/html/lvs/rrd"
......
# vim graph-lvs.sh
......
    WORKDIR="/var/www/html/lvs/rrd"
    RRDTOOL="/usr/local/rrdtool/bin/rrdtool"
    GRAPHS="/var/www/html/lvs/graphs"
    WEBPATH="/lvs/graphs"
......
# vim lvs-rrd.php
......
    <?php
    header("Cache-Control: max-age=300, must-revalidate");
    system("/var/www/html/lvs/graph-lvs.sh -H");
    ?>
......
5、创建rrd绘图目录，并修改文件权限
# mkdir /var/www/html/lvs/rrd
chown  -R apache lvs/
6、配置周期收集数据，并开启服务
# vim /etc/crontab
    * * * * *  root /var/www/html/lvs/lvs.rrd.update
# /etc/init.d/httpd restart
# chkconfig  httpd on
7、在nagios里设置监控lvs的url
......
define host{
        use                     templete_hangzhou_callcenter
        host_name               hangzhou_server_lvs_master
        alias                   hangzhou_server_lvs_master
        address                 192.168.2.231
        hostgroups              hostgroup_servyou_hosts
        parents                 hangzhou_serverswitch_02
        icon_p_w_picpath              redhat_server.gif
        icon_p_w_picpath_alt          redhat5.0
        statusmap_p_w_picpath         redhat_server.gd2
        parents                 hangzhou_serverswitch_02
        notes_url               http://192.168.2.231/lvs  #nagios监控lvs的url
}
.....
