centos安装 MUNIN
http://www.ff-bb.cn/logs/167741012.html
MUNIN是一个基于WEB界面的系统监视工具
MUNIN的安装有2种方式，一个是去munin上下载源代码进行编译，不过要解决不少依赖问题。
二是进行yum安装，这样可以避免依赖问题。
centos默认情况下不能进行munin的yum安装。先要安装yum-priorities
1;
用于 CentOS 5 安装源的 yum-priorities 软件包:
yum install yum-priorities
i386 http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.i386.rpm
x86_64 http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm
2.
我的centos是64位的，下载如下:
wget http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm
3;
rpm -Uvh rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm
[root@192 ~]# cd /etc/yum.repos.d/
[root@192 yum.repos.d]# ls
CentOS-Base.repo CentOS-Base.repo.bak mirrors-rpmforge
CentOS-Base.repo.5 CentOS-Media.repo rpmforge.repo
有了这个RPMforge Repository的源就可以开始yum 安装munin
4 服务端安装
#yum install munin munin-node
安装完毕之后
#cd /etc/munin
# ls
munin.conf munin-node.conf plugins
munin-node.confdafault plugins.conf
plugin-conf.d templates
需要在你web服务器的静态目录中创建一个目录 munin
#mkdir -p /usr/local/nginx/html/htdocs/munin/
#chown -R munin:munin /usr/local/nginx/html/htdocs/munin/
简单设置 munin的配置文件/etc/munin/munin.conf
vi /etc/munin/munin.conf
dbdir /var/lib/munin
htmldir /usr/local/nginx/html/htdocs/munin/
logdir /var/log/munin
rundir /var/run/munin
tmpldir /etc/munin/templates
[localhost]
address 127.0.0.1
use_node_name yes
＃添加一个客户端
[db]
address 172.32.1.1
use_node_name yes
设置 munin启动脚步并启动 munin
#chkconfig --levels 235 munin-node on
#/etc/init.d/munin-node start
Starting Munin Node: [ OK ]
# ps fax|grep munin
11627 pts/2 S+ 0:00 \_ grep munin
11548 ? Ss 0:00 /usr/sbin/munin-node
#cd /var/log/munin
# ls
munin-graph.log munin-limits.log munin-update.log
munin-html.log munin-node.log
# tail -f /var/log/munin/munin-html.log

5;客户端安装,我的客户端也是centos5.6
在客户端主机上,只需要安装munin-node就可以了
yum install -y munin-node
cd /etc/munin
vi munin-node.conf
添加服务端的ip
allow ^172\.32\.1\.19$ #这个就是munin主服务器上的IP,允许这个IP对我的访问.
#/etc/init.d/munin-node restart
cat /var/log/munin/munin-node.log
在apache/nginx中配置一个虚拟主机
<VirtualHost *:80>
ServerName www.ff-bb.cn
DocumentRoot "/var/www/html/munin"
</VirtualHost>
过几分钟，访问这个域名即可看到数据。
