Cacti学习笔记一:基本安装和配置
1.安装依赖包
yum -y install net-snmp-devel mysql mysql-devel openssl-devel libtool
2.安装RRDTool
yum -y install rrdtool
3.安装snmp
yum -y install net-snmp net-snmp-utils
4.安装LAMP
yum -y install httpd mysql-server php php-mysql service httpd start service mysql start
5.安装cacti
下载: wget http://www.cacti.net/downloads/cacti-0.8.8h.tar.gz tar xf cacti-0.8.8h.tar.gz 创建账号: useradd -m cacti passwd cacti 初始化数据库: create user 'cacti'@'localhost' identified by 'cacti'; create database cacti; grant all on cacti.* to 'cacti'@'localhost'; cd cacti-0.8.8h mysql -uroot -p cacti < cacti.sql 如果没有密码,直接回车 创建rrd账号 useradd cactiuser mv cacti-0.8.8h /var/www/html/cacti cd /var/www/html/cacti chown -R cactiuser rra log */5 * * * * root /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 加入/etc/crontab 出现时间安全问题,修改php.ini date.timezone = Asia/Shanghai 去掉注释病修改
6.配置cacti
vim /var/www/html/cacti/include/config.php $database_type = "mysql"; $database_default = "cacti"; $database_hostname = "localhost"; $database_username = "cacti"; $database_password = "cacti"; $database_port = "3306"; $database_ssl = false;
7.增加spine,优化的轮询
wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.8a.tar.gz tar -xvf cacti-spine-0.8.8a.tar.gz cd cacti-spine-0.8.8a ./configure make && make install cp /usr/local/spine/etc/spine.conf.dist /usr/local/spine/etc/spine.conf vim /usr/local/spine/etc/spine.conf DB_Host localhost DB_Database cacti DB_User cacti B_Pass cacti DB_Port 3306 DB_PreG 0
测试和数据库是否可以通信
配置cacti使用spine轮询

查看日志
tail -f /var/www/html/cacti/log/cacti.log

轮询方法由cmd.php改变为spine
常见问题
没有数据: 查看tail -f /var/www/html/cacti/log/cacti.log是否每隔5分钟出现日志,如果没有检查定时任务 如果crontab不支持,使用脚本 [root@monitor shell]# cat /root/shell/foreach_cacti.sh #!/bin/bash (while true; do /usr/bin/php /var/www/html/cacti/poller.php > /dev/null; sleep 60; done) &
