centos5.7 编译安装cacti

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 http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.5.tar.gz
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 http://www.cacti.net/downloads/spine/cacti-spine-0.8.7h.tar.gz
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 cacti@localhost 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/

http://ip/cacti

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
