编译安装cacti

#原有php没有启用snmp 所以先启用

yum install net-snmp-devel net-snmp-utils -y

#进入php源码目录

cd /usr/local/src/php/src/php-5.2.17/ext/snmp

./configure --with-php-config=/usr/local/php1/bin/php-config make && make install

#编辑php.ini  加入

extension = "snmp.so"

#重启php-fpm

/usr/local/php1/sbin/php-fpm restart

 

#安装cacit

1、安装rrdtools

cd /opt/src wget yum install pango-devel tar xvf rrdtool-1.4.5.tar.gz cd rrdtool-1.4.5 ./configure --prefix=/opt/rrdtool make && make install #让rrdtool支持中文显示 vi src/rrd_graph.c 在原来setlocale(LC_CTYPE,"")的位置增加以下内容

setlocale(LC_ALL,"zh_CN.gb2312");

 

2、安装spine

wget cd /opt/src tar xvf cacti-spine-0.8.7h.tar.gz cd cacti-spine-0.8.7h ./configure --prefix=/opt/spine make && make install

修改spine配置文件

cd /opt/spine/etc cp spine.conf.dist spine.conf vi spine.conf  DB_Host         localhost  DB_Database     cacti  DB_User         cacti  DB_Pass         cactiuser  DB_Port         3306  DB_PreG         0

3、安装cacti

建立用户

useradd cacti

cd /opt/src tar xvf cacti-0.8.7h.tar.gz mv cacti-0.8.7h /home/www/cacti chown -R root:root /home/www/cacti 修改配置文件(按实际信息修改) vi home/www/cacti/include/config.php

 $database_type = "mysql";

 $database_default = "cacti";  $database_hostname = "localhost";  $database_username = "cactiuser";  $database_password = "cactiuser";  $database_port = "3306";  $database_ssl = false;

#创建一个数据库并导入数据

/usr/local/mysql/bin/mysql -u root -p mysql> create database cacti; mysql> grant all privileges on cacti.* to identified by "cactiuser"; mysql> flush privileges;  /usr/local/mysql/bin/mysql -u root -p  cacti < /home/www/cacti/cacti.sql   cd /home/www/cacti chown -R cacti rra/ log/

按实际路径设置

默认用户名和密码  admin

定时执行

yum install vixie-cron

crontab -u cacti -e  */1 * * * * /usr/local/php1/bin/php /home/www/cacti/poller.php > /dev/null 2>&1

注意:如果在path中 提示找不到路径的话 检查php.ini 是否设置了open_basedir

故障排除

无数据检查过程  检查是否有数据返回   snmpwalk -v 2c -c public 10.0.2.88 if  rrdtool 是否有数据   /opt/rrdtool/bin/rrdtool fetch 13.rrd AVERAGE  还有就是要注意选择的模板是否正确
