来源：互联网发布：多宝视网络弱视训练编辑：程序博客网时间：2024/04/29 11:28

Cacti的功能与用途这里就不多做介绍了，但它并不是万能的，例如无法统计某个IP段的流量情况，期待新版或Mod能让其真正强大起来。

一、Apache＋PHP＋Mysql安装

(1). apache安装

下载

wget http://apache.justdn.org/httpd/httpd-2.0.55.tar.gz

解压

tar zxvf httpd-2.0.55.tar.gz

如果没有最大化安装as4或没有安装以下包，编译会报错

可手动安装编译环境，或在添加删除应用程序中选中安装-开发工具

rpm –ivh xxxxx.rpm #xxxxx.rpm包安装顺序如下：

1、glibc-kernheaders-2.4-8.10.i386.rpm
2、binutils-2.13.90.0.18-9.i386.rpm
3、cpp-3.2.2-5.i386.rpm
4、glibc-devel-2.3.2-11.9.i386.rpm
5、glibc-common-2.3.2-11.9.i386.rpm
6、gcc-3.2.2-5.i386.rpm

配置

cd httpd-2.0.55

./configure --prefix=/usr/local/apache-2.0.55 /

--with-mpm=prefork /

--enable-vhost-alias /

--enable-rewrite /

--enable-expires /

--enable-so

编译并安装

make && make install

(2).修改配置文件

cd /usr/local/apache-2.0.55/conf

vi httpd.conf

KeepAlive Off #把on改成off,关闭持久连接

StartServers 5

MinSpareServers 5

MaxSpareServers 10

ServerLimit 4000 #添加这一行,一定要大于MaxClients，但要小于20000

MaxClients 2000 #根据内存大小，一般情况下是1G内存2000

MaxRequestsPerChild 0

</IfModule>

注： ServerName 可修改为域名或本机ip

cd /usr/loca/apache-2.0.55/bin

启动：./apachectl start

关闭：./ apachectl stop

(3).添加PHP模块，并支持Mysql

1.mysql的安装

cd /soft/

下载

wget http://dev.mysql.com/get/Downloads/MySQL-4.0/mysql-4.0.26.tar.gz/from/http://mysql.byungsoo.net/

解压

tar zxvf mysql-4.0.26.tar.gz

配置

cd mysql-4.0.26

./configure –prefix=/usr/local/mysql-4.0.26

编译并安装

make

make install

启动mysql:端口3306

cd /soft/mysql-4.0.26

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

groupadd mysql #添加mysql用户和组

useradd –g mysql mysql

/usr/local/mysql-4.0.26/bin/mysql_install_db #初始化权限表

chown –R mysql:mysql /usr/local/mysql-4.0.26/var #更改目录所属组

/usr/local/mysql-4.0.26/bin/mysqld_safe & #启动mysql

两次回车

mysql

/usr/local/mysql-4.0.26/bin/mysqladmin shutdown #关闭mysql

2.php编译参数

下载

wget http://cn2.php.net/get/php-4.4.1.tar.gz/from/cn.php.net/mirror

解压

tar zxvf php-4.4.1.tar.gz

安装 jpegsrc.v6b.tar.gz 和 libpng-1.2.8-config.tar.gz，否则提示错误“libjpeg.(a|so) not found.”

配置

./configure --prefix=/usr/local/php-4.4.1 /

--with-apxs2=/usr/local/apache-2.0.55/bin/apxs /

--with-iconv /

--with-mysql=/usr/local/mysql-4.0.26 /

--with-gd /

--with-jpeg-dir=/usr/local /

--with-png-dir /

--with-zlib /

--enable-gd-native-ttf /

# 以下参数是安装cacti时才用到

--enable-sockets /

--with-snmp /

--enable-ucd-snmp-hack

编译并安装

make && make install

3.拷贝及修改php.ini

cd /soft/ php-4.4.1/

cp php.ini-dist /usr/local/php-4.4.1/lib/php.ini

修改配置文件

vi /usr/local/php-4.4.1/lib/php.ini

memory_limit = 84M

display_errors = Off

log_errors = Off #日志记录可不必开启

log_errors_max_len = 10240

error_log = /hdp1/v2/log/php_error.txt #目录手动添加

post_max_size = 82M

upload_max_filesize = 80M

4.修改apache的httpd.conf文件添加如下一行，让它能够解析.php文件

cd /usr/local/apache-2.0.55/conf/

vi httpd.conf

要添加到AddType相关的行

AddType application/x-httpd-php .php

重启apache

cd /usr/local/apache-2.0.55/bin/

./apachectl stop

./apachectl start

(4).添加虚拟主机

cd /usr/local/apache-2.0.55/conf/

vi httpd.conf

NameVirtualHost *:80

ServerName www.zcom.com

DocumentRoot /home/www/www.zcom.com ＃目录需要手工建立

ErrorLog /dev/null

CustomLog /dev/null common

</VirtualHost>

二、SNMP安装和配置

(3).redhat

如果系统安装的时候没有安装可以先装一个apt,然后用apt-get install net-snmp来安装

修改配置文件

vi /etc/snmp/snmpd.conf

修改如下两行

com2sec notConfigUser default zengyu

access notConfigGroup "" any noauth exact mib2 none none

去掉下面几行前面的“#”

com2sec local localhost COMMUNITY

com2sec mynetwork NETWORK/24 COMMUNITY

group MyRWGroup any local

group MyROGroup any mynetwork

view all included .1 80

view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc

access MyROGroup "" any noauth 0 all none none

access MyRWGroup "" any noauth 0 all all all

开启：

setup

在system service选中snmp

执行service snmpd start

三、rrdtool-1.2.11安装

安装libart

wget http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/libs/libart_lgpl-2.3.17.tar.gz

tar zxvf libart_lgpl-2.3.17.tar.gz

cd libart_lgp-2.3.17

./configure

make

make install

安装 libcgi

wget http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/libs/cgilib-0.5.tar.gz

tar zxvf cgilib-0.5.tar.gz

cd cgilib-0.5

make

cp libcgi.a /usr/local/lib

cp cgi.h /usr/include

【安装 libcgi

wget http://lists.ee.ethz.ch/p/cgilib-0.5.1.tar.gz

tar zxvf cgilib-0.5.1.tar.gz

cd cgilib-0.5.1

./configure

make && make install

cd libcgi

cp cgi.h /usr/include】

安装 libpng

wget http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/libs/libpng-1.2.8-config.tar.gz

tar zxvf libpng-1.2.8-config.tar.gz

cd libpng-1.2.8-config/

./configure

make

make install

安装freetype

wget http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/libs/freetype-2.1.9.tar.gz

tar zxvf freetype-2.1.9.tar.gz

cd freetype-2.1.9

./configure

make

make install

cd /usr/include

ln -sf /usr/local/include

安装 rrdtool

wget http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/rrdtool-1.2.11.tar.gz

tar zxvf rrdtool-1.2.11.tar.gz

cd rrdtool-1.2.11

./configure --prefix=/usr/local/rrdtool-1.2.11 /

--disable-tcl /

--disable-python

make

make install

四、安装cacti

前提条件：mysql,apache,php,rrdtool, snmp

(1.) 下载并安装

cd /usr/local/apps/www

wget http://www.cacti.net/downloads/cacti-0.8.6g.tar.gz

tar zxvf cacti-0.8.6g.tar.gz

mv cacti-0.8.6g cacti

cd cacti

(2).打补丁

wget http://www.cacti.net/downloads/patches/0.8.6g/short_open_tag_parse_error.patch

wget http://www.cacti.net/downloads/patches/0.8.6g/graph_properties_zoom.patch

wget http://www.cacti.net/downloads/patches/0.8.6g/script_server_snmp_auth.patch

wget http://www.cacti.net/downloads/patches/0.8.6g/mib_file_loading.patch

patch -p1 -N < short_open_tag_parse_error.patch

patch -p1 -N < graph_properties_zoom.patch

patch -p1 -N < script_server_snmp_auth.patch

patch -p1 -N < mib_file_loading.patch

(3)配置mysql数据库

#mysql

mysql> create database cacti;

mysql> grant all privileges on cacti.* to cacti@123.123.123.123 identified by ‘cacti’;

mysql> flush privileges;

mysql>quit

导入库：

mysql --database=cacti </usr/local/apps/www/cacti/cacti.sql

配置cacti连接数据库

#vi /usr/local/apps/www/cacti/include/config.php

$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “123.123.123.123”;
$database_username = “cacti”;
$database_password = “cacti”;

注：123.123.123.123是本机IP地址

(4).定时运行cacti收集数据

/etc/crontab -e

添加一行：

*/5 * * * * /usr/local/php-4.4.1/bin/php /usr/local/apps/www/cacti/poller.php >/dev/null 2>&1

修改apache配置文件httpd.conf，添加默认访问文件index.php

cacti的使用配置：

第一次进入需要配置，RRDTOOL路径修改为/usr/local/rrdtool-1.2.11/bin/rrdtool

第一次进入，用admin/admin，然后会提示修改密码，然后即可进入。

settingà修改rrdtool版本，默认是1.0.x，修改为1.2.x，否则图片显示不出来

在device下添加要监控的设备；修改设备，添加SNMP-Interface监控；在newgraph下选中设备添加该设备网卡；在tree中添加该设备。

测试：/usr/local/apps/php/bin/php /usr/local/apps/www/cacti/poller.php

如遇到cacti/log/cacti.log中显示无法连接local的mysql，做如下处理：

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
