Cacti安装配置

Nagios安装配置

监控软件Cacti搭建

环境准备

安装epel扩展源

1	yum install -y epel-release

搭建lamp环境

1	[root@cacti ~]# yum install -y httpd php php-mysql mysql mysql-server mysql-devel php-gd libjpeg libjpeg-devel libpng-devel

/etc/init.d/httpd start
/etc/init.d/mysqld start
#初始化mysql
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h cacti password 'new-password'
#或者
/usr/bin/mysql_secure_installation

服务端

安装cacti监控主机

1	yum install -y cacti net-snmp net-snmp-utils rrdtool net-snmp-devel net-snmp-libs lm-sensors php-xml zlib libpng freetype cairo-devel pango-devel gd

/etc/init.d/snmpd start
#新建cacti数据库
mysql -u root
mysql> create database cacti;
mysql> grant all on cacti.* to 'cactiuser'@'localhost' identified by 'cactiuser'; 
mysql> exit
#导入cacti数据库结构
mysql -u root cacti < /usr/share/doc/cacti-0.8.8b/cacti.sql
#设置cacti配置文件中的mysql数据库账号密码
vim /usr/share/cacti/include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactiuser";
$database_port = "3306";
$database_ssl = false;
 
#修改httpd中的cacti配置
vim /etc/httpd/conf.d/cacti.conf
Deny from all 修改为 Allow from all
#重启httpd
/etc/init.d/httpd restart

通过浏览器访问
如果访问不了，请检查主机的iptables和selinux
到了登陆，默认的账号为admin，密码为admin
登陆之后，系统会强制用户更改密码
点击graphs-Default Tree-Host Localhost，进入系统监控界面
我们看到监控界面，没有出图，设置一下出图

crontab -e
# 让命令每5分钟执行一次
*/5 * * * * /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1

我们在刷新一下，图就出来了, 数据需要等待一会儿，才能出来

接下来我们添加被监控的主机

客户端

在被监控的主机上安装

1	yum install -y net-snmp lm_sensors

vim /etc/snmp/snmpd.conf

#syslocation Unknown (edit /etc/snmp/snmpd.conf)
syslocation 192.168.1.118
 
#       group          context sec.model sec.level prefix read   write  notif
access  notConfigGroup ""      any       noauth    exact  all none none
 
view all    included  .1                               80    去掉注释符“#”

启动 snmpd

1	/etc/init.d/snmpd start

使用

依次点击console -> Devices -> add,添加主机
开始添加被监控主机的信息，填写完毕，点击Create
创建完毕，看是否通信正常，创建完主机，创建要监控的项目点击 Create Graphs for this Host，
根据需要，去选择要监控的项目
监控项目添加完毕，将主机添加到监控主干线上，点击左侧Graph Trees
点击Add，添加被监控的主机
- 类型选择Host，再选择要添加的主机
- 添加完毕，点击Save
到主界面查看，是否添加成功，最好在监控服务器上刷新一下
