Linux-Cacti监控{Verson:1.2.8}

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

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

Vim /etc/php.ini

成功

MySQL - 时区支持

Shell>mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql

输入密码解决mysql 的时区问题

最后 MYSQL设置

首先vim /etc/my.cnf

再mysqld下添加一条

version

5.5.64-MariaDB

5.6

可忽略版本问题

collation_server

latin1_swedish_ci

utf8mb4_unicode_ci

解决:

Set global collation_server=utf8mb4_unicode_ci;

character_set_client

latin1

utf8mb4

解决:

Set global character_set_client=utf8mb4;

max_allowed_packet

1048576

16777216

解决:

Set global max_allowed_packet=17700000;

join_buffer_size

15M

解决:

set global join_buffer_size=20971520;

innodb_file_per_table

OFF

解决;

Set global innodb_file_per_table=ON

innodb_file_format

Antelope

Barracuda

解决;

Set global innodb_file_format=Barracuda

innodb_large_prefix

OFF

解决;

Set global innodb_large_prefix=1

innodb_flush_log_at_trx_commit

解决;

Set global innodb_flush_log_at_trx_commit=2

然后点击下一页,继续安装.

目录权限检查

脚本:

#!/bin/bash

chmod a+w /var/www/html/cacti/resource/snmp_queries/

chmod a+w /var/www/html/cacti/resource/script_server/

chmod a+w /var/www/html/cacti/resource/script_queries/

chmod a+w /var/www/html/cacti/scripts/

chmod a+w /var/www/html/cacti/log/

chmod a+w /var/www/html/cacti/cache/boost/

chmod a+w /var/www/html/cacti/cache/mibcache/

chmod a+w /var/www/html/cacti/cache/realtime/

chmod a+w /var/www/html/cacti/cache/spikekill/

设置监控周期时间范围填写自己网段范围[需要监控的] 点击附加选项值下一步

一路下一页开始安装

-------添加设备--------

在被监控的客户机上

Yum -y install net-snmp

Vim /etc/snmp/snmpd.conf 添加

//取消注释

Vim /etc/hosts

添加新设备;

成功

---------如不显示图像------

如要快速收集则在监控服务端输入

/usr/bin/php /var/www/html/cacti/poller.php

完成数据采集

若要实现自动采集;

添加计划周期表:

在监控服务墙上:

#: crontab -u cacti -e

*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null

意义: 每五分钟输入一次 php /var/www/html/cacti/poller.php 实现自动采集
