时间：2007-04-06 来源：shanxueyi
一、apache＋PHP＋Mysql+cacit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
配置
cd httpd-2.0.55
./configure --prefix=/usr/local/apps/apache2 \
--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/apps/apache2/conf
vi httpd.conf
KeepAlive Off #把on改成off,关闭持久连接
<IfModule prefork.c>
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>
cd /usr/loca/apps/apache2/bin
启动：./apachectl start
(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/apps/mysql
编译并安装
make && make install
启动mysql:端口3306
cp /soft/mysql-4.0.26/support-files/my-medium.cnf /etc/my.cnf
y
groupadd mysql #添加mysql用户和组
useradd –g mysql mysql
/usr/local/mysql/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/bin/mysqld_safe & #启动mysql
等待一会，然后回车
输入mysql，如果提示输入mysql的root密码，则代表开启成功，或者用
netstat –an，查看有无3306端口
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
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 \
--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/lib/php.ini
memory_limit = 84M
display_errors = Off
log_errors = On
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
vi /usr/local/apache-2.0.55/conf/httpd.conf
添加这行：
AddType application/x-httpd-php .php DirectoryIndex
添加虚拟主机
cd /usr/local/apache-2.0.55/conf/
vi httpd.conf
NameVirtualHost *:80
<VirtualHost *:80>
ServerName www.zcom.com
DocumentRoot /home/www/www.zcom.com
ErrorLog /dev/null
CustomLog /dev/null common
</VirtualHost>
重启apache
cd /usr/local/apache/bin/
./apachectl stop
./apachectl start
建立测试页面
cd /home/www/www.zcom.com
vi index.php
随意输入内容，保存退出
测试：http://ip/index.php
二、SNMP安装和配置
vi /etc/snmp/snmpd.conf
修改如下两行
com2sec notConfigUser default zcom
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
(4).freebsd
Vi /usr/local/share/snmp/snmpd.conf添加如下一行
rocommunity zcom
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://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 /home/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 –u root –p
mysql> create database cacti;
mysql> grant all privileges on cacti.* to cacti@localhost identified by ‘cacti’;
mysql>quit
导入库：
mysql -p --database=cacti </home/www/cacti/cacti.sql
导出：
/usr/local/mysql-4.0.26/bin/mysqldump –B –uroot -p cacti > /root/cacti_bak.sql
配置cacti连接数据库
#vi /home/www/cacti/include/config.php
$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “localhost”;
$database_username = “cacti”;
$database_password = “cacti”;
(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 /home/www/cacti/poller.php >/dev/null 2>&1
测试执行：ln –s /home/www/cacti /home/www/www.zcom.com/cacti
修改apache配置文件httpd.conf，添加默认访问文件index.php
DirectoryIndex index.php index.html index.html.var #line:396
访问：http://www.zcom.com/cacti/index.php
cacti的使用配置：http://mail.zcom.com/cacti
第一次进入需要配置，显示个工具/服务等的路径时，需要确认没有红字NOT FOUND，例如RRDTOOL第一次就会显示红字，修改为/usr/local/rrdtool-1.2.11/bin/rrdtool，点Finish。
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/php-4.4.1/bin/php /home/www/cacti/poller.php
