使用dtree构建动态树型菜单

cacti完全配置

安装mysql

groupadd mysql

useradd mysql -c "start mysqld's account" -d /dev/null -g mysql - s /sbin/nologin

./configure \
--prefix=/usr/local/mysql \
--with-mysqld-user=mysql \
--without-debug \
--with-client-ldflags=-all-static \
--with-mysqld-ldflags=-all-static \
--disable-shared \
--localstatedir=/var/lib/mysql \
--without-isam \
--without-innodb \
--enable-assembler
make

make install

cd support-files/

cp support-files/my-medium.cnf /etc/my.cnf

cd /usr/local/mysql

/usr/local/mysql/bin/mysql_install_db --user=mysql

chown -R root:mysql /usr/local/mysql/

chown -R mysql:mysql /var/lib/mysql

/usr/local/mysql/bin/mysqld_safe --user=mysql &

/usr/local/mysql/bin/mysqladmin -u root -p password cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysql

cd /etc/init.d

chmod 755 mysql

chkconfig --add mysql

chkconfig --level 3 mysql on
安装apache

tar -zxvf httpd-2.0.50.tar.gz
cd httpd-2.0.50
./configure --prefix=/usr/local/apache2 --enable-module=so --enable-rewrite
Make
Make instll
设置自启动
cp support/apachectl /etc/init.d/httpd

修改/etc/init.d/httpd
vi /etc/init.d/httpd(在第两行之后添加如下内容)
#!/bin/sh
#
# Startup script for the Apache Web Server
# chkconfig: - 85 15
# description: Apache is a World Wide Web server. It is used to serve \
# HTML files and CGI.
# processname: httpd
# pidfile: /usr/local/apache/log/httpd.pid
# config: /usr/local/apache/conf/httpd.conf
chkconfig --add httpd
chmod 755 /etc/init.d/httpd
chkconfig httpd on

安装php

Tar –zxvf php-5.1.2.tar.gz
./configure--with-apxs2=/usr/local/apache2/bin/apxs--with-mysql=/usr/local/mysql/--with-gd--with-jpeg-dir=/usr/lib--enable-gd-native-ttf--with-zlib-dir=/usr/lib --with-png --with-png-dir=/usr/lib --with-freetype=/usr/lib --with-ttf --enable-sockets
Make
Make instll
cp php.ini-dist /usr/local/lib/php.ini
vi /usr/local/apache/conf/httpd.conf
加入以下代码：
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps
AddType application/x-tar .tgz

AddType image/x-icon .ico
建立测试页面：info.php,添加以下内容：
<?
phpinfo();
?>
设置mysql

/usr/local/mysql/bin/mysql –uroot –p
create database cactidb;
grant all on cactidb.* to root;
grant all on cactidb.* to root@localhost;
grant all on cactidb.* to cactiuser;
grant all on cactidb.* to cactiuser@localhost;
set password for cactiuser@localhost=password('######');
exit
安装rrdtool

Tar –zxvf rrdtool-1.0.50.tar.gz
./configure –prefix=/usr/local/rrdtool
Make
Make install
与mrtg相比,rrdtool自带了gd库,所以不用先安装gd库.(不过由于rrdtool自带的gd库不支持中文,所以rrdtool画出来的图也不能有中文,否则会出现乱码).

安装net-snmp

Cacti需要用到net-snmp中的两个命令――snmpwalk和snmpget进行数据的采集。需要安装以下软件包：
net-snmp-5.1.2-11.i386.rpm
net-snmp-devel-5.1.2-11.i386.rpm
net-snmp-libs-5.1.2-11.i386.rpm
net-snmp-perl-5.1.2-11.i386.rpm
net-snmp-utils-5.1.2-11.i386.rpm
我们可以直接在系统中运行snmpwalk和snmpget看是否有该命令
安装cacti

Tar –zxvf cacti-0.8.6i.tar.gz
Cp –rf cacti-0.8.6i /usr/local/apache/htdocs/cacti
Cd cacti
cat cacti.sql |/usr/local/mysql/bin/mysql cactidb -uroot -p
chown –R cactiuser rra/ log/
vi /usr/local/apache/htdocs/cacti/include/config.php
配置以下代码：
$database_type = “mysql”;

$database_default = “cactidb”;

$database_hostname = “localhost”;

$database_username = “cactiuser”;

$database_password = “######”;
Useradd cactiuser –d /dev/null –s /sbin/nologin
crontab –u cactiuser –e
*/5 * * * * /usr/local/bin/php /usr/local/apache2/htdocs/cacti/poller.php > /dev/null 2>&1
页面设置

在浏览器上输入：
http://IP/cacti
进入cacti的初始设置页面：
在这里我们要输入一些原始的信息：
注意路径的正确性
安装完成

Cacti系统设置

为了让cacti能取到我们需要的数据，比如CPU和系统负载的数据，我们需要对snmpd.conf这个文件进行设置，其原因应该是snmp设置默认没有允许取这些数据。
打开默认的/etc/snmp/snmpd.conf文件,更改如下配置:
# sec.name source community

com2sec notConfigUser default public
将"comunity"字段改为你要设置的密码.比如"123456".

将“default”改为“安装了cacti机器的IP”

# Finally, grant the group read-only access to the systemview view.

# group context sec.model sec.level prefix read write notif

access notConfigGroup "" any noauth exact all none none

将"read"字段改为all.
## incl/excl subtree mask

#view all included .1 80

将该行前面的"#"去掉.
重新启动snmpd
Service snmpd restart
Chkconfig –-level 3 snmpd on
查看snmp的端口号

[root@localhost snmp]# netstat -ln|grep 161

udp 0 0 0.0.0.0:161 0.0.0.0:*
如果看到161端口，说明snmpd服务器启动成功。

1．开始建立我们的配置模板：
因为cacti提供很多配置模板，这里我们选择Generic SNMP-enabled Host 模板：
console----Host Templates----Generic SNMP-enabled Host，添加以下数据取样：
Host Templates [edit: Generic SNMP-enabled Host]

Name

A useful name for this host template.

Associated Graph Templates

1) Host MIB - Logged in Users

2) Host MIB - Processes

3) ucd/net - CPU Usage

4) ucd/net - Load Average

5) ucd/net - Memory Usage

6) Unix - Ping Latency

Add Graph Template: Cisco - CPU Usage Host MIB - Available Disk Space Host MIB - CPU Utilization Interface - Errors/Discards Interface - Non-Unicast Packets Interface - Traffic (bits/sec) Interface - Traffic (bits/sec, 95th Percentile) Interface - Traffic (bits/sec, Total Bandwidth) Interface - Traffic (bytes/sec) Interface - Traffic (bytes/sec, Total Bandwidth) Interface - Unicast Packets Karlnet - Wireless Levels Karlnet - Wireless Transmissions Linux - Memory Usage Netware - CPU Utilization Netware - Directory Information Netware - File System Activity Netware - File System Cache Netware - Logged In Users Netware - Open Files Netware - Volume Information SNMP - Generic OID Template ucd/net - Available Disk Space Unix - Available Disk Space Unix - Load Average Unix - Logged in Users Unix - Processes

Associated Data Queries

1) SNMP - Get Mounted Partitions

2) SNMP - Interface Statistics

Add Data Query: Karlnet - Wireless Bridge Statistics Netware - Get Available Volumes Netware - Get Processor Information SNMP - Get Processor Information ucd/net - Get Monitored Partitions Unix - Get Mounted Partitions

点击‘save’保存退出。
下面开始添加设备：

console----Devices----add，输入该主机描述，ip地址，点击create创建完成。
然后把主机添加默认树：
console----Graph TreesGrap----Default Tree----add----Tree Item Type（host）----tetle（主机ip），然后就完成了。
