篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Linux-Cacti监控{Verson:1.2.8}相关的知识，希望对你有一定的参考价值。

首先需要一个LAMP平台或LNMP平台

yum -y install httpd mariadb php mariadb-server mariadb-devel zlib freetype libjpeg \\
fontconfig gd libxml2 php-gd php-mysql cairo-devel libxml2-devel glib2 glib2-devel libpng \\
libpng-devel freetype-devel libart_lgpl pango pango-devel perl-CPAN        //所有环境

关闭防火墙和黑盒子以免排错问题

Systemctl stop firewalld && systemctl disable firewalld

Service firewalld stop

Setenforce 0

测试LAMP平台:

Vim /var/www/html/index.php

添加

<?php

Phpinfo();

?>

Systemctl start httpd && systemctl enable httpd

Systemctl start mariadb && systemctl enable mariadb

访问测试:

成功

下一步

cacti监控需要协议: snmp

Yum -y install net-snmp

Yum -y install net-snmp-utils ///需要在被监控的PC 与监控PC上下载

Systemctl start snmpd

下载 rddtool 链接:https://oss.oetiker.ch/rrdtool/pub/rrdtool-1.7.0.tar.gz

Cd /root/rrd-version

./configre --prefix=/usr/local --做这一步可以直接跳过优化路径

Make && make install

2.下载cacti:https://www.cacti.net/downloads/cacti-1.2.8.tar.gz //cacti 包绿色免安装

3.添加用户cacti

Useradd cacti

将cacti包放在html目录下并基于属组属主

Tar zxf cacti-1.2.8.tar.gz -C /var/www/html/

Cd /var/www/html

Mv cacti-1.2.8 cacti

Chown -R cacti.cacti cacti/

创建cacti数据库并授权,并导入数据

CREATE DATABASE cacti DEFAULT CHARACTER SET utf8;

GRANT all ON cacti.* TO \'cacti\'@\'localhost\' IDENTIFIED BY \'123.com\';

------------进入数据库,并且导入数据------------

mysql>use cacti;

mysql> source /var/www/html/cacti/cacti.sql

Mysql>flush privileges; //刷新数据库

Mysqladmin -u root password 123.com //为root用户设置一个密码

修改cacti配置文件

Vim /var/www/html/cacti/include/config.php

修改以下配置文件为自己所需的

$database_type = \'mysql\';

$database_default = \'cacti\';

$database_hostname = \'localhost\';

$database_username = \'cacti\';

$database_password = \'123.com\';

$database_port = \'3306\';

$database_retries = 5;

$database_ssl = false;

$database_ssl_key = \'\';

$database_ssl_cert = \'\';

$database_ssl_ca = \'\';

访问cacti页面并进行排错

http://192.168.9.6/cacti/index.php

访问报错:System log file is not available for writing, please enable write access Log: /var/www/html/log/cacti.log

Touch /var/www/html/log/cacti.log && chmod a+w /var/www/html/log/cacti.log

chown -R cacti.cacti /var/www/html/cacti/rra

若一直无法访问则

[root@swarm-node-work1192 html]# chmod -R a+r cacti

开始一个错一个错解决

PHP推荐配置;

version	5.4.16	>= 5.4.0	通过	PHP 5.4.0 是最低版本要求
memory_limit	128M	>= 800M	警告	至少 800M MB 内存
max_execution_time	30	>= 60	警告	至少 60 m 执行时间
date.timezone		>=	错误	A valid timezone that matches MySQL and the system
