cacti的基本安装（一）
以下测试是经安装cacti成功出图后笔记，仅供参考：首先，下载cacti环境所需包：
httpd-2.2.6.tar.gz，mysql-5.1.37.tar.gz，libxml2-2.6.28.tar.gz，cacti-0.8.7e.tar.gz
gettext-0.16.1.tar.gz，libpng-1.2.18.tar.gz，rrdtool-1.2.27.tar.gz
curl-7.15.0.tar.gz ，zlib-1.2.3.tar.gz，freetype-2.3.5.tar.gzjpegsrc.v6b.tar.gz
gd-2.0.35.tar.gz ，libart_lgpl-2.3.17.tar.gzphp-5.1.6.tar.gz
还有net-snmp包，我在实验中使用是rpm安装。
解压下载的包后，分别进入解压目录进行下列安装
1.安装Apache
./configure --prefix=/usr/local/apache2 --enable-module=so --with-mpm=worker --enable-module=rewrite
make && make install
/usr/local/apache2/bin/apachectl start
IE访问http://ip/出现”It works!”，说明apache安装成功。
2.安装mysql
groupadd mysql
useradd –g mysql mysql
./configure --prefix=/usr/local/mysql --localstatedir=/opt/data/ --with-extra-charsets=gbk
make && make install
cpsupport-files/my-medium.cnf /etc/my.cnf
cd /usr/local/mysql
bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/opt/mydata
chown -R mysql.mysql .
/usr/local/mysql/bin/mysqld_safe --user=mysql --datadir=/opt/mydata &
/usr/local/mysql/bin/mysqladmin –u root –p password '123456'
Enter password:直接回车
/usr/local/mysql/bin/mysql –u root –p
Enter password: ----123456
3.插件相关：编译安装libxml
./configure --prefix=/usr/local/libxml2/
make && make install
4.编译安装zlib
./configure --prefix=/usr/local/zlib2/
make && make install
5.编译安装jpeg
mkdir /usr/local/jpeg6/include-p
mkdir /usr/local/jpeg6/lib
mkdir /usr/local/jpeg6/bin
mkdir /usr/local/jpeg6/man/man1 –p
./configure --prefix=/usr/local/jpeg6
make install-lib
make install
6.编译安装libpng
cp scripts/makefile.gcmmx makefile
./configure --disable-shared --prefix=/usr/local/libpng2/
make && make install
7.编译安装freetype
./configure --disable-shared --prefix=/usr/local/freetype2/
make && make install
8.编译安装libart_lgpl
./configure --disable-shared --prefix=/usr/local/libart/
make && make install
9.编译安装gettext
./configure --prefix=/usr/local/gettext/
make && make install
10.安装编译gd
./configure --prefix=/usr/local/gd2 --with-zlib=/usr/local/zlib2/ --with-png=/usr/local/libpng2/ --with-jpeg=/usr/local/jpeg6/ --with-
freetype=/usr/local/freetype2/ --with-libart=/usr/local/libart/ --with-gettext=/usr/local/gettext/ --with-libxml=/usr/local/libxml2/
make && make install
11.编译curl
./configure --prefix=/usr/local/curl
make && make install
12.编译安装PHP
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-jpeg-dir=/usr/local/jpeg6/ --with-png-
dir=/usr/local/libpng2/ --with-gd --with-freetype-dir=/usr/local/freetype2/ --with-zlib-dir=/usr/local/zlib2/ --with-mysql=/usr/local/mysql --
with-curl=/usr/local/curl --with-libxml-dir=/usr/local/libxml2 --with-gettext=/usr/local/gettext --enable-sockets
make&&make install
cp php.ini-dist /usr/local/php/lib/php.ini
vi /usr/local/apache2/conf/httpd.conf
在#AddType application/x-tar.tgz填加
AddType application/x-httpd-php .php
AddType image/x-icon .ico
找到 DirectoryIndex行，添加index.php保存
/usr/local/apache2/bin/apachectl restart
13.安装rrdtool
./configure --prefix=/usr/local/rrdtool
make && make install
在实验时，出现下面的错误：
configure: error: Please fix the library issues listed above and try again.
解决：安装libart_lgpl-devel这个包，rpm 包或者源码包都可以
14.安装net-snmp（使用rpm包，也可以编译）
yum -y install net-snmp*
配置snmp：
vi /etc/snmp/snmpd.conf (只修改一行）
#view all included .1 80（去掉#）
保存启动：service snmpd start
15.安装配置cacti
useradd cactiuser
tar zxvf cacti-0.8.7e.tar.gz
mv cacti-0.8.7e /usr/local/apache2/htdocs/cacti
chown -R cactiuser:cactiuser /usr/local/apache2/htdocs/cacti
在Mysql中创建新的database，导入cacti目录中的cacti.sq创建表：
/usr/local/mysql/bin/mysql –u root –p
Enter Password: 123456
mysql> create database cacti;
mysql> use cacti;
mysql> source /usr/local/apache2/htdocs/cacti/cacti.sql;
grant all on cacti.* to root; （权限的设置）
grant all on cacti.* to root@localhost;
grant all on cacti.* to cactiuser;
grant all on cacti.* to cactiuser@localhost;
set password for cactiuser@localhost=password('cactipw');
vi /usr/local/apache2/htdocs/cacti/include/config.php
$database_password=“cactipw”; （只改这行）
打开浏览器http://IP/cacti
提示安装：需要修改前2个路径：
RRDTool Binary Path： /usr/local/rrdtool/bin/rrdtool
PHP Binary Path：/usr/local/php/bin/php
安装完成
首次登陆默认账号：admin密码admin
登陆后系统会强制立即修改密码
/usr/local/php/bin/php /usr/local/apache2/htdocs/cacti/poller.php > /dev/null 2>&1 (手动生成图像文件:位
于/usr/local/apache2/htdocs/cacti/rra下)
snmpwalk -v 1 127.0.0.1 -c public若没错误则说明snmp没有问题
crontab –e：如下每5分钟更新图像统计信息
*/5 * * * */usr/local/php/bin/php /usr/local/apache2/htdocs/cacti/poller.php> /dev/null 2>&1
查看http://ip/cacti（下图是我过了一段时间截的图）
