cacti安装

Cacti是一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。它通过snmp来获取数据，使用RRDtool绘画图形

下面开始准备安装：

首先看看gcc有没有安装：
[root@localhost ~]# rpm -qa |grep gcc
gcc44-c++-4.4.0-6.el5
gcc-objc-4.1.2-48.el5
gcc-c++-4.1.2-48.el5
gcc-4.1.2-48.el5
gcc44-4.4.0-6.el5
gcc-gfortran-4.1.2-48.el5
libgcc-4.1.2-48.el5
gcc-gnat-4.1.2-48.el5
gcc44-gfortran-4.4.0-6.el5

//第一：开始安装apache服务：
[root@localhost ~]# tar -zxvf httpd-2.2.6.tar.gz

[root@localhost ~]# cd httpd-2.2.6

[root@localhost httpd-2.2.6]# ./configure --prefix=/usr/local/apache --enable-so

[root@localhost httpd-2.2.6]# make && make install

//启动apache服务
[root@localhost ~]# /usr/local/apache/bin/apachectl start

//把apache服务加入开机启动项
[root@localhost ~]# echo "/usr/local/apache/bin/apachectl start" >>/etc/rc.local

 第二，安装mysql

//添加mysql用户组
[root@localhost ~]# groupadd mysql

//添加mysql用户，并添加到mysql用户组中
[root@localhost ~]# useradd -g mysql mysql

[root@localhost ~]# tar -zxvf mysql-5.0.45.tar.gz

[root@localhost ~]# cd mysql-5.0.45

[root@localhost mysql-5.0.45]# ./configure --prefix=/usr/local/mysql

[root@localhost mysql-5.0.45]# make && make install

[root@localhost mysql-5.0.45]# cp support-files/my-medium.cnf /etc/my.cnf

[root@localhost mysql]# chown -R mysql .

[root@localhost mysql]# chgrp -R mysql .

[root@localhost mysql]# ./bin/mysql_install_db --user=mysql

[root@localhost mysql]# chown -R mysql var/

[root@localhost mysql]# ./bin/mysqld_safe --user=mysql &

[root@localhost mysql]# cd /root/mysql-5.0.45

[root@localhost mysql-5.0.45]# cp support-files/mysql.server /etc/init.d/mysqld

[root@localhost mysql-5.0.45]# chmod 755 /etc/init.d/mysqld

[root@localhost mysql-5.0.45]# chkconfig --level 345 mysqld on

[root@localhost ~]# mysqladmin -uroot password tiger

第三，准备安装PHP
//安装zlib
[root@localhost]# tar -zxvf zlib-1.2.3.tar.gz

[root@localhost]# cd zlib-1.2.3

[root@localhost zlib-1.2.3]# ./configure --prefix=/usr/local/zlib

[root@localhost zlib-1.2.3]# make && make install

//安装libpng
[root@localhost ~]# tar -zxvf libpng-1.2.23.tar.gz

[root@localhost ~]# cd libpng-1.2.23

[root@localhost libpng-1.2.23]# ./configure --prefix=/usr/local/libpng

[root@localhost libpng-1.2.23]# make && make install

//安装freetype
[root@localhost ~]#  tar -xvf freetype-2.3.10.tar.bz2

[root@localhost ~]#  ls

[root@localhost ~]#  cd freetype-2.3.10

[root@localhost freetype-2.3.10]#   ls

[root@localhost freetype-2.3.10]#  ./configure --prefix=/usr/local/freetype

[root@localhost freetype-2.3.10]#  make && make install

[root@localhost freetype-2.3.10]#  cd /usr/local/freetype/

//安装jpeg
//用yum安装的jpeg fontconfig gd

//开始安装PHP
[root@localhost]# tar -zxvf php-5.2.5.tar.gz

[root@localhost php-5.2.5]# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --with-png-dir=/usr/local/libpng --with-freetype-dir=/usr/local/freetype --enable-gd-native-ttf --with-ttf --enable-gd-jis-conv --enable-xml --enable-mbstring --enable-sockets

[root@localhost php-5.2.5]# make && make install
在这行下边
LoadModule php5_module modules/libphp5.so
添加
AddType application/x-httpd-php .php

找到DirectoryIddex index.html index.html.var
修改为
 DirectoryIndex index.html index.html.var index.php

[root@localhost php-5.2.5]# /usr/local/apache2/bin/apachectl restart

如果出现问题，无法解析PHP文件，将
LoadModule php5_module modules/libphp5.so
下的
AddType application/x-httpd-php .php
注释掉

重新在
AddType application/x-gzip .gz .tgz
下添加这么一行就OK了
AddType application/x-httpd-php .php

第四 ，安装rrdtool
//安装rrdtool必须安装以下安装包，为了方便就直接用yum安装了。
[root@localhost ]# yum install cairo-devel libxm12-devel pango-devel pango libpng-devel freetye freetype-devel libart_lgpl-devel intltool

[root@localhost]# tar -zxvf rrdtool-1.0.49.tar.gz

[root@localhost]# cd rrdtool-1.0.49

[root@localhost rrdtool-1.0.49]# ./configure --prefix=/usr/local/rrdtool -disable-tcl

[root@localhost rrdtool-1.0.49]# make && make install

[root@localhost rrdtool-1.0.49]# ln -s /usr/local/rrdtool/bin/* /usr/local/bin/

第五，开始安装cacti

[root@aca400fe ~]# tar -zxvf cacti-0.8.7i.tar.gz

[root@aca400fe ~]# mv cacti-0.8.7i/* /usr/local/apache/htdocs/

mv: overwrite `/usr/local/apache/htdocs/index.php'? y //由于前期安装lamp的时候新建了个index.php在这就需要覆盖下

[root@aca400fe ~]# useradd cacti

[root@aca400fe ~]# chown -R cacti /usr/local/apache/htdocs/rra

[root@aca400fe ~]# chown -R cacti /usr/local/apache/htdocs/

[root@aca400fe ~]# chgrp -R cacti /usr/local/apache/htdocs/

//登录MySQL，新建数据，并授权

[root@aca400fe ~]# mysql -uroot -p
Enter password:

Bye
[root@aca400fe ~]# cd /usr/local/apache/ho
-bash: cd: /usr/local/apache/ho: No such file or directory
[root@aca400fe ~]# cd /usr/local/apache/htdocs/
[root@aca400fe htdocs]# ls

//导入cacti数据库

[root@aca400fe htdocs]# mysql -uroot -phuye cacti <cacti.sql
[root@aca400fe htdocs]# cd in
include/    index.html  index.php   install/   
[root@aca400fe htdocs]# cd include/

//将/usr/local/apache/htdocs/include/config.php修改成下边这样

[root@aca400fe include]# vi config.php

/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti";
$database_port = "3306";
//$database_ssl = false;

/* Default session name - Session name must contain alpha characters */
#$cacti_session_name = "Cacti";

[root@aca400fe include]# cd /usr/local/php/bin/
[root@aca400fe bin]# ls
pear  peardev  pecl  php  php-config  phpize

被监控的机器上要开启snmp服务

第五，安装net-snmp
[root@localhost ~]# tar -zxvf net-snmp-5.7.1.tar.gz

[root@localhost ~]# cd net-snmp-5.7.1

[root@localhost net-snmp-5.7.1]# ./configure --prefix=/usr/local/net-snmp --enable-developer

[root@localhost net-snmp-5.7.1]# make && make install

[root@localhost net-snmp-5.7.1]# cp EXAMPLE.conf /usr/local/net-snmp/share/snmp/snmp.conf

[root@aca400fe snmp]# ln -s /usr/local/net-snmp/bin/* /usr/local/bin/

[root@aca400fe snmp]# /usr/local/net-snmp/sbin/snmpd -c /usr/local/net-snmp/share/snmp/snmp.conf

 

用主机以下面方式登陆：
//IP/install
