cd /usr/local/mysql
scripts/mysql_install_db --user=mysql
chown -R root .
chown -R mysql data
chgrp -R mysql .
/usr/local/mysql/bin/mysqld_safe --user=mysql &
./bin/mysqladmin -uroot password mysql
cp ../mysql-5.0.51/support-files/my-large.cnf /etc/my.cnf
cp ../mysql-5.0.51/support-files/mysql.server /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
chkconfig --level mysqld 345 on
chkconfig --list mysqld

 

-----------------------------------------------------------------------------------

 

安装apache

cd /usr/local/src
tar zxfv httpd-2.0.59.tar.gz
cd httpd-2.0.59
./configure --prefix=/usr/local/apache --with-mpm=prefork --enable-so --enable-modules=all
make;make install
cp /usr/local/apache/bin/apachectl /etc/init.d/httpd
cd /etc/rc3.d
ln -s /etc/init.d/httpd S85httpd
ln -s /etc/init.d/httpd K85httpd
/usr/local/apache/bin/apachectl start

-----------------------------------------------------------------------------------

 

安装PHP
安装支持图形处理，自己可以找最新的安装。
##### zlib#####

cd zlib-1.2.3
./configure --prefix=/usr/local/zlib
make
make install
cd ..

##### FreeType ##### freetype-2.3.5.tar.gz

cd freetype-2.3.5

./configure --prefix=/usr/local/freetype

make
make install
cd ..

##### LibPNG #####

cd libpng-1.2.20

cp scripts/makefile.linux makefile

make test
make install
cd ..

##### Jpeg ##### jpegsrc.v6b.tar.gz

cd jpeg-6b

mkdir /usr/local/jpeg
mkdir /usr/local/jpeg/bin
mkdir /usr/local/jpeg/lib
mkdir /usr/local/jpeg/include
mkdir /usr/local/jpeg/man

--with-zlib
make
make install

注：libart-2.0，libpng，freetype2（安装时就./configure）
然后ln -s /usr/local/include/libart-2.0 /usr/include/libart-2.0
ln -s /usr/local/include/freetype2 /usr/include/freetype2

安装PHP
tar -zxvf php-5.2.5.tar.gz
cd php-5.2.5
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-
mysql=/usr/local/mysql --with-config-file-path=/usr/local/php/etc --with-openssl --with-gd=/usr/local/gd --
with-gdbm=/usr/lib --with-freetype-dir=/usr/local/freetype  --with-jpeg-dir=/usr/local/jpeg --with-png-dir --with-
zlib=/usr/local/zlib --enable-mbstring --enable-sockets
make;make install
cp php.ini-dist /usr/local/php/etc/php.ini
vi /usr/local/apache/conf/httpd.conf
添加       AddType application/x-tar .tgz
           AddType application/x-httpd-php .php

设置mysql

/usr/local/mysql/bin/mysql -u root -pmysql
      mysql> create database cactidb;
　　mysql> grant all on cactidb.* to root;
　　mysql> grant all on cactidb.* to ;
　　mysql> grant all on cactidb.* to cactiuser;
　　mysql> grant all on cactidb.* to ;
　　mysql> set password for );
注：以上语句输出 Query OK, 0 rows affected (0.01 sec) 表示成功
　　mysql> exit

 

-----------------------------------------------------------------------------------

 

检测apache + php + mysql
cd （apache目录）
touch info.php
vi info.php
                        phpinfo( );
            ?>
保存退出 ：wq
[root @tsai htdocs]# touch mydqltest.html
[root @tsai htdocs]# vi mysqltest.html
     
        
                           $link=mysql_connect('localhost','root');
                mysql_select_db('mysql');
               $str="select * from user;";
               $result=mysql_query($str,$link);
               $show=mysql_num_rows($result);
               mysql_close($link);
               for ($i=0;$i < $show;$i++)
                   {
                 $arr[$i]=mysql_fetch_array($result);
                   };
            ?>

         
            
            
            
         
    
         
           
           
           
        
            
         
      
保存退出 ：wq

安装/ 配置cacti
useradd cactiuser -g users
passwd cactiuser (pwd:cactipw)
cp cacti-0.8.7.tar.gz /apache目录
cd /apache目录
tar -zxvf cacti-0.8.7.tar.gz
mv cacti-0.8.6g cacti
cd cacti
/usr/local/mysql/bin/mysql -u root -p cactidb < cacti.sql
passwork:
chown -R cactiuser rra/ log/
cd scripts
chown cactiuser:users *
vi /apache目录/cacti/include/config.php
$database_type = “mysql”;
$database_default = “cactidb”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “cactipw”;
更改用户、密码 等项 与上面给出的对应 保存退出
crontab -u cactiuser -e 
加入
*/5 * * * * /usr/local/php/bin/php /apache目录/cacti/poller.php > /dev/null 2>&1

 

-----------------------------------------------------------------------------------

 

全部设置完毕。
打开浏览器 http://服务器IP/cacti 进入cacti的初始设置页面
第一次默认登陆账号：admin 密码 admin
登陆后在新改个密码就OK
需要说明的还有路径
/usr/bin/snmpwalk
/usr/bin/snmpget
/usr/bin/snmpbulkwalk
/usr/bin/snmpgetnext
/usr/local/rrdtool-1.2.23/bin/rrdtool
/www/cacti/log/cacti.log
/usr/local/php/bin/php

注：此时graphs还不能显示图形，需要将服务重新启动一下
service snmpd restart
service mysql restart
