大纲
一、cacti简述
二、配置nginx、php、mysql
三、cacti + spine 搭建
一、简述
Cacti基于SNMP采集数据源，通过rrdtool储存数据并绘图呈现给用户。SNMP获取的数据源为.rrd文件，存储在cacti目录下的rra目录。
工作流程如图：
二、配置nginx、php、mysql（忽略LNMP环境部署过程）
1.配置nginx
#在nginx中加入一个server
[root@jpushoa_6.213 cacti-spine-0.8.8h]$vim /usr/local/nginx/conf/nginx.conf
server {
listen 8888;
access_log log/access_catic.log main;
location / {
index index.html index.php;
root /usr/local/cacti/;
}
location ~.*\.(php|php5)?$ {
root /usr/local/cacti/;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/cacti/$fastcgi_script_name;
include fastcgi_params;
}
location = /favicon.ico {
log_not_found off;
access_log off;
}
}
#添加完成后，测试配置文件语法是否正常
[root@jpushoa_6.213 cacti-spine-0.8.8h]$/usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
#创建cacti日志文件
[root@jpushoa_6.213 cacti-spine-0.8.8h]$touch /usr/local/nginx/log/access_cacti.log
#更改nginx及子目录的属主属组
[root@jpushoa_6.213 cacti-spine-0.8.8h]$chown -R nginx.nginx /usr/local/nginx/
#启动nginx
[root@jpushoa_6.213 cacti-spine-0.8.8h]$/usr/local/nginx/sbin/nginx
#查看nginx启动的端口
[root@jpushoa_6.213 cacti-spine-0.8.8h]$netstat -ntlp | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 29641/nginx
tcp 0 0 0.0.0.0:8888 0.0.0.0:* LISTEN 29641/nginx 2.配置php：
#更改php.ini时区
[root@jpushoa_6.213 cacti-spine-0.8.8h]$vim /etc/php.ini
date.timezone =Asia/Shanghai
#更改php-fpm的属主属组
[root@jpushoa_6.213 conf]$vim /etc/php-fpm.d/www.conf
user = nginx
group = nginx
#启动php-fpm并查看其端口状态
[root@jpushoa_6.213 conf]$service php-fpm start
Starting php-fpm: [ OK ]
[root@jpushoa_6.213 conf]$netstat -ntlp | grep php
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 3773/php-fpm
#新建session目录并更改目录属主属组及权限（/etc/php-fpm.d/www.conf中有定义session路径）
[root@jpushoa_6.213 local]$mkdir -p /var/lib/php/session
[root@jpushoa_6.213 local]$chown nginx.nginx /var/lib/php/session
[root@jpushoa_6.213 local]$chmod -R 770 /var/lib/php/session 3.创建并导入cacti数据库及用户密码授权
mysql> create database cacti;
mysql> use cacti;
mysql> \. /usr/local/cacti/cacti.sql
mysql> create user 'cactiuser'@'192.168.%.%' identified by 'cactipasswd';
mysql> grant all on cacti.* to 'cactiuser'@'192.168.%.%' identified by 'cactipasswd';
mysql> flush privileges; 三、cacti＋spine搭建
#1.安装snmp
[root@jpushoa_6.213 ~]$yum -y install net-snmp net-snmp-utils net-snmp-devel
#更改团体名和ObjectID（团体名可保持默认）:
[root@cacti ~]# vim /etc/snmp/snmpd.conf
#修改前一：
com2sec notConfigUser default public
#修改后一：
com2sec notConfigUser default TEST
#修改前二：
view systemview included .1.3.6.1.2.1.1
#修改后二：
view systemview included .1
#启动snmpd服务：
[root@jpushoa_6.213 ~]$service snmpd start
Starting snmpd: [ OK ]
#SNMP数据采集测试：
[root@jpushoa_6.213 ~]$snmpnetstat -v 2c -c TEST -Cna -Cp tcp 127.0.0.1
Active Internet (tcp) Connections (including servers)

[root@jpushoa_6.213 ~]$yum -y install rrdtool rrdtool-devel#3.安装cacti
[root@jpushoa_6.213 data]$wget http://www.cacti.net/downloads/cacti-0.8.8h.tar.gz
[root@jpushoa_6.213 ~]$tar zxvf cacti-0.8.8h.tar.gz -C /usr/local/
[root@jpushoa_6.213 ~]$cd /usr/local/
[root@jpushoa_6.213 local]$mv cacti-0.8.8h/ cacti /
[root@jpushoa_6.213 local]$chown -R nginx.nginx cacti/
#修改cacti配置文件：
[root@jpushoa_6.213 local]$vim cacti/include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "192.168.6.213";
$database_username = "cactiuser";
$database_password = "cactipasswd";
$database_port = "3306";
$database_ssl = false;#4.安装spine
[root@jpushoa_6.213]$wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.8h.tar.gz
[root@jpushoa_6.213 ~]$tar zxvf cacti-spine-0.8.8h.tar.gz
[root@jpushoa_6.213 cacti-spine-0.8.8h]$./configure --prefix=/usr/local/spine/
[root@jpushoa_6.213 cacti-spine-0.8.8h]$make && make install
[root@jpushoa_6.213 cacti-spine-0.8.8h]$chown -R nginx.nginx /usr/local/spine/
[root@jpushoa_6.213 cacti-spine-0.8.8h]$cp /usr/local/spine/etc/spine.conf.dist /usr/local/spine/etc/spine.conf
#修改spine配置文件：
[root@jpushoa_6.213 cacti-spine-0.8.8h]$vim /usr/local/spine/etc/spine.conf
DB_Host 192.168.6.213
DB_Database cacti
DB_User cactiuser
DB_Pass cactipasswd
DB_Port 3306
#测试spine是否安装成功：
[root@jpushoa_6.213 local]$spine/bin/spine -C spine/etc/spine.conf
SPINE: Using spine config file [spine/etc/spine.conf]

#a.打开浏览器，输入cacti服务器IP地址及端口（默认80，无需输入），进入安装界面，如下图，点击Next:
#b.根据实际情况选择安装或升级，我们是全新安装，故选择Nex Install，然后Next：
#c.检查所有路径配置，配置正确会提示OK,用绿色字体标出；一般无需更改，我们直接Finish:
#d.提示用户名密码，默认都为admin。输入后点击Login:
#e.此时会提示强制更改密码，输入新密码后Save，即登陆cacti管理界面
#f.进入“console-configuration-settings-General“，找到SNMP Defaults，更改SNMP Version
为Version 2；更改SNMP Community为你设置的团体名，默认为public。
#g.进入“console-configuration-settings-Pathes“下，找到Alternate Poller Path,在Spine
Poller File Path后填入你安装spine时的路径并保存，正常则会提示"OK：FILE FOUND"
#h.进入“console-configuration-settings-Poller”，更改Poller Type为spine（默认为cmd.php)，修改Poller Interval、Cron Interval为你设置的任务计划时间并保存。
#i.到此，cacti安装已完成。cacti默认有把本机加入监控，可查看图形显示效果。点击管理界面最左上角的“graphs-Default Tree-Host:Localhost":
