Centos5.2下Cacti安装配置
一、编译安装基本环境
使用 yum 程序安装所需开发包（以下为标准的 RPM 包名称）
#rpm –import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#yum -y install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison utoconf automake bzip2-devel curses-devel zlib-devel ibjpeg-devel libpng-devel libtiff-devel freetype-devel libXpm-devel gettext-devel pam-devel kernel
二、 编译安装软件包
源码编译安装所需包(Source)
1) GD2
# cd /usr/local/src
# tar xvf gd-2.0.35.tar.gz
# cd gd-2.0.35
# ./configure –prefix=/usr/local/gd2
# make
# make install
2) LibXML2
# cd /usr/local/src
# tar xvf libxml2-2.6.29.tar.bz2
# cd libxml2-2.6.29
# ./configure –prefix=/usr/local/libxml2
# make
# make install
3) LibMcrypt
# cd /usr/local/src
# tar xvf libmcrypt-2.5.8.tar.bz2
# cd libmcrypt-2.5.8
# ./configure –prefix=/usr/local/libmcrypt
# make
# make install
4). OpenSSL和OpenSSH
# cd /usr/local/src
# tar xvf openssl-0.9.8g.tar.gz
# cd openssl-0.9.8g
# ./config –prefix=/usr/local/openssl
# make
# make test
# make install
# cd ..
# tar xvf openssh-5.0p1.tar.gz
# cd openssh-5.0p1
# ./configure \
”–prefix=/usr” \
”–with-pam” \
”–with-zlib” \
”–sysconfdir=/etc/ssh” \
”–with-ssl-dir=/usr/local/openssl” \
”–with-md5-passwords”
# make
# make install
配置：
1) 禁用 SSH V1 协议
# vi /etc/ssh/ssh_config
找到#Protocol 2,1改为：Protocol 2
2) 禁用服务器端GSSAPI
找到以下两行，并将它们注释：
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
3) 禁用 DNS 名称解析
找到：#UseDNS yeas改为：UseDNS no
4)禁用客户端 GSSAPI
# vi /etc/ssh/ssh_config 找到：
GSSAPIAuthentication yes
将这行注释掉。
最后，确认修改正确后重新启动 SSH 服务
# service sshd restart
# ssh -v
确认 OpenSSH 以及 OpenSSL 版本正确。
三、编译安装A.M.P环境
1.下载软件编译安装
1)下载软件
# cd /usr/local/src
httpd-2.2.8.tar.gz
mysql-5.0.51b.tar.gz
php-5.2.6.tar.bz2
2) 安装MySQL
查看分析你的CPU型号:
http://gentoo-wiki.com/Safe_Cflags 查找您的GCC编译参数.
确定系统CPU类型：
# cat /proc/cpuinfo | grep “model name”
执行后会看到系统中CPU的具体型号，记下CPU型号。
# tar xvf mysql-5.0.51b.tar.gz
# cd mysql-5.0.51b
# vi mysql.sh
CHOST=”i686-pc-linux-gnu”
CFLAGS=”-march=prescott -O2 -pipe -fomit-frame-pointer”
CXXFLAGS=”${CFLAGS}”
./configure \
”–prefix=/usr/local/mysql” \
”–localstatedir=/data/mysql/data” \
”–with-comment=Source” \
”–with-server-suffix=-LinuxTone” \
”–with-mysqld-user=mysql” \
”–without-debug” \
”–with-big-tables” \
”–with-charset=gbk” \
”–with-collation=gbk_chinese_ci” \
”–with-extra-charsets=all” \
”–with-pthread” \
”–enable-static” \
”–enable-thread-safe-client” \
”–with-client-ldflags=-all-static” \
”–with-mysqld-ldflags=-all-static” \
”–enable-assembler” \
”–without-isam” \
”–without-innodb” \
”–without-ndb-debug”
make && make install
mkdir -p /data/mysql/data
useradd mysql -d /data/mysql -s /sbin/nologin
/usr/local/mysql/bin/mysql_install_db –user=mysql
cd /usr/local/mysql
chown -R root:mysql .
chown -R mysql /data/mysql/data
cp share/mysql/my-huge.cnf /etc/my.cnf
cp share/mysql/mysql.server /etc/rc.d/init.d/mysqld
chmod 755 /etc/rc.d/init.d/mysqld
chkconfig –add mysqld
/etc/rc.d/init.d/mysqld start
cd /usr/local/mysql/bin
for i in *; do ln -s /usr/local/mysql/bin/$i /usr/bin/$i; done
#sh mysql.sh 即可开始编译.
3) 编译安装Apache
# cd /usr/local/src
# tar xvf httpd-2.2.8.tar.gz
# cd httpd-2.2.8
./configure \
”–prefix=/usr/local/apache2″ \
”–with-included-apr” \
”–enable-so” \
”–enable-deflate=shared” \
”–enable-expires=shared” \
”–enable-rewrite=shared” \
”–enable-static-support” \
”–disable-userdir”
make
make install
echo ‘/usr/local/apache2/bin/apachectl start ‘ >> /etc/rc.local
4).编译安装PHP
# cd /usr/local/src
# tar xjvf php-5.2.6.tar.bz2
# cd php-5.2.6
./configure \
”–prefix=/usr/local/php” \
”–enable-discard-path” \
”–enable-force-cgi-redirect” \
”–with-config-file-path=/usr/local/php/etc” \
”–enable-zend-multibyte” \
”–with-mysql=/usr/local/mysql” \
”–with-mysqli=/usr/local/mysql/bin/mysql_config” \
”–with-libxml-dir=/usr/local/libxml2/bin” \
”–with-xmlrpc” \
”–with-gd=/usr/local/gd2″ \
”–with-jpeg-dir” \
”–with-png-dir” \
”–with-bz2″ \
”–with-freetype-dir” \
”–with-zlib-dir ” \
”–with-openssl=/usr/local/openssl” \
”–with-mcrypt=/usr/local/libmcrypt” \
”–enable-sysvsem” \
”–enable-inline-optimization” \
”–enable-soap” \
”–enable-gd-native-ttf” \
”–enable-ftp” \
”–enable-mbstring” \
”–enable-exif” \
”–disable-debug” \
”–disable-ipv6″ \
”–enable-sockets” \
”–with-snmp”
make
make install
mkdir /usr/local/php/etc
cp php.ini-dist /usr/local/php/etc/php.ini
2、整合Apache与PHP及系统初化配置.
1)整合Apache与PHP
# vi /usr/local/apache2/conf/httpd.conf
找到：
AddType application/x-gzip .gz .tgz
在该行下面添加
AddType application/x-httpd-php .php
找到：
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>
将该行改为
<IfModule dir_module>
DirectoryIndex index.html index.htm index.php
</IfModule>
找到：
#Include conf/extra/httpd-mpm.conf
#Include conf/extra/httpd-info.conf
#Include conf/extra/httpd-vhosts.conf (虚拟主机配置文件存放目录.)
#Include conf/extra/httpd-default.conf
去掉前面的”#”号，取消注释。
注意：以上 4 个扩展配置文件中的设置请按照相关原则进行合理配置！
修改完成后保存退出。
# /usr/local/apache2/bin/apachectl restart
2)查看确认L.A.M.P环境信息
在网站根目录放置 info.php 脚本，检查phpinfo中的各项信息是否正确。
<?php
phpinfo();
?>
3)配置虚拟主机:
#vi /usr/local/apache2/conf/extra/httpd-vhosts.conf
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin hamgua@gmail.com
DocumentRoot “/data/www/wwwroot”
ServerName cacti.test.comServer
Alias cacti.test.cn
# ErrorLog “logs/dummy-host.example.com-error_log”
# CustomLog “|/usr/sbin/cronolog /data/logaccess_www.linuxtone.org.%Y%m%d” combined
</VirtualHost>
四、安装采集工具
SNMP全名是简单网络管理协议，几乎所有的网络设备（交换机、路由器等）和操作系统默认安装了认都安装了snmp服务。
Cacti 系统所在的服务器并不一定要安装SNMP服务，但是Cacti系统采集数据要用到Net-SNMP包里面的几个工具，所以最好也在Cacti服务器上安装 SNMP服务。我们可以直接在系统中运行snmpwalk和snmpget看是否有该命令，如果有则无需安装了。
如果操作系统没有安装SNMP,可以到本文最后的资源里的Net-SNMP官方网站上下载源码或二进制包进行安装。
#yum -y install net-snmp*
#rpm -qa|grep snmp
net-snmp-libs-5.3.1-24.el5_2.2
net-snmp-perl-5.3.1-24.el5_2.2
net-snmp-utils-5.3.1-24.el5_2.2
net-snmp-5.3.1-24.el5_2.2
net-snmp-devel-5.3.1-24.el5_2.2
五、安装rrdtool
我这里使用的是rpm包安装
#wget
ftp://rpmfind.net/linux/fedora/updates/9/i386.newkey/rrdtool-1.3.4-2.fc9.i386.rpm
#rpm -ivh rrdtool-1.3.4-2.fc9.i386.rpm
warning: rrdtool-1.3.4-2.fc9.i386.rpm:
Header V3 DSA signature: NOKEY, key ID 6df2196f
error: Failed dependencies:
dejavu-lgc-fonts is needed by rrdtool-.3.4-2.fc9.i386
#yum -y install dejavu-lgc-fonts
#rpm -ivh rrdtool-1.3.4-2.fc9.i386.rpm
warning: rrdtool-1.3.4-2.fc9.i386.rpm: Header V3 DSA signature: NOKEY, key ID 6df2196f
Preparing… ###########################################[100%]

六、安装配置cacti
下载cacti的源码包
#wget http://www.cacti.net/downloads/cacti-0.8.7b.tar.gz
#tar zvxf cacti-0.8.7b.tar.gz
#mv cacti-0.8.7b /data/www/wwwroot/cacti
#cd /data/www/wwwroot/cacti
配置帐号及mysql：
groupadd cactiuser
add -g cacti cactiuser
mysql -uroot -p
mysql> create database cactidb;
mysql> grant all on cactidb.* to root;
mysql> grant all on cactidb.* to root@localhost;
mysql> grant all on cactidb.* to cactiuser;
mysql> grant all on cactidb.* to cactiuser@localhost identified by ‘123456’;
mysql> flush privileges;
mysql> exit
Catci配置：
# mysql cactidb -uroot -p < cacti.sql
# chown -R cactiuser rra/ log/
# chmod -R 777 rra/ log/
# vi include/config.php
$database_type = “mysql”;
$database_default = “cactidb”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “123456”;
$database_port = “3306”;
配置让系统每五分钟去取一次snmp数据：
#crontab -u cactiuser -e //注意要用cactiuser就是你刚刚建立的那个帐号去运行crontab
*/5 * * * * /usr/local/php/bin/php /data/www/wwwroot/cacti/poller.php > /dev/null 2>&1
七、客户端snmp配置
#yum -y install net-snmp*
#vi /etc/snmp/snmpd.conf
# SNMP configfile for Linux servers
com2sec local 127.0.0.1 public
com2sec local 192.168.22.0/24 public
group MyROGroup v1 local
group MyROGroup v2c local
group MyROGroup usm local
view all included .1 80
access MyROGroup “” any noauth exact all none nones
yslocation (/etc/snmpd/snmpd.conf)
syscontact Me <hamgua@gmail.com>
#service snmpd restart
八、配置完成
打开浏览器输入
http://ip/cacti
输入用户名密码,默认的是admin，admin
然后提示修改密码
好了配置结束
尽情的去享受cacti吧！
