LNMP架构安装配置方法 http://9272317.blog.51cto.com/9262317/1826042
实验过程中关闭防火墙和selinux
service iptables stop setenforce 0
官网下载cacti相关软件
root@localhost file]# wget http://www.cacti.net/downloads/cacti-0.8.8a.tar.gz http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.5.tar.gz
安装rrdtool采集工具
安装rrdtool之前需要安装相应的lib库，如下安装：
yum install cairo-devel libxml2-devel pango pango-devel perl-devel -y
tar xzf rrdtool-1.4.5.tar.gz;cd rrdtool-1.4.5; ./configure --prefix=/data/local/rrdtool/;make &&make install ln -s /data/local/rrdtool/bin/* /usr/local/bin/
安装SNMP服务
yum install net-snmp net-snmp-utils -y
安装cacti主程序
tar xzf cacti-0.8.8a.tar.gz && mv cacti-0.8.8a /usr/local/nginx/html/
创建cacti数据库
service mysqld restart
mysql 进入创建数据库：
mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

创建数据库
mysql> create database cacti; Query OK, 1 row affected (0.00 sec)
创建用户并授权
mysql> grant all on cacti.* to cacti@‘localhost‘ identified by "123456"; Query OK, 0 rows affected (0.00 sec)
刷新权限
flush privileges;
把数据导入到数据库：
mysql -u cacti -p cacti < cacti /cacti .sql
配置php的数据库连接部分,改用户名和密码
[root@localhost ~]# vim /usr/local/nginx/html/cacti-0.8.8a/include/config.php

[root@localhost ~]# chmod -R 777 /usr/local/nginx/html/cacti/rra/ [root@localhost ~]# chmod -R 777 /usr/local/nginx/html/cacti/log/
重启网站服务 service nginxd restart
添加Rrdtool抓图任务计划
crontab -e
*/1 * * * * /usr/bin/php /usr/local/nginx/html/cacti/poller.php >>/tmp/cacti_rrdtool.log 2 >&1
启动smmp
[root@localhost ~]# /etc/init.d/snmpd restart 停止 snmpd： [失败] 正在启动 snmpd： [确定] [root@localhost ~]# /etc/init.d/snmptrapd restart 停止 snmptrapd： [失败] 正在启动 snmptrapd： [确定]
浏览器里面查看安装
http://192.168.72.250/cacti/install/
有界面提示进行全新安装 安装后添加devices graph trees，再查看devices里面的status状态是否为up，up才算成功，
如果一直是unkown,那么可以
测试snmp返回数据的是否正确：
snmpwalk -v2c -c public localhost
手动抓图后再观察status是否为up：
/usr/bin/php /usr/local/nginx/html/cacti/poller.php
添加一个远程主机
在远程主机上安装snmpd服务
yum install net-snmp net-snmp-utils -y
修改配置文件vi /etc/snmp/snmpd.conf
vi /etc/snmp/snmpd.conf，我们只需要更改：62行把他改为：
access notConfigGroup "" any noauth exact all none none
第二：我们需要更改42行为：
com2sec notConfigUser 192.168.1.16 public #注意：如果是服务器端这里的IP要改成你要监控的远程客户端的IP
（其中192.168.1.16 ip 表示你允许那台服务器可以监控你。public 表示团体名）
第三：我们还要更改：86行：把#号去掉：变成如下即可
view all included .1 80
最后重启snmpd服务ok ：
service snmpd restart
如果发现监控的主机不出图，状态始终为unkown.那就同步下时间。
yum install -y ntpdate
ntpdate us.pool.ntp.org
然后清空掉 /usr/local/nginx/html/cacti/rra下抓取的数据
手动抓取下 /usr/bin/php /usr/local/nginx/html/cacti/poller.php
再看下 /usr/local/nginx/html/cacti/rra下 是否有远程主机的IP开头的文件
比如 192_168_1_17_hdd_free_100.rrd
localhost_traffic_in_35.rrd
此时应该有图了
排错：有图无数据
vi /usr/local/php/php.ini
将php.ini中设置date.timezone的值为PRC，设置好以后的为：date.timezone=PRC，同时取消这一行代码的注释，即去掉前面的分号就可以了。
tail -f /var/log/cron
tail -f /var/spool/mail/root 即可查看最近的crontab执行情况 这里的值有数据 Processes:1 Threads:N/A Hosts:3 HostsPerProcess:3 DataSources:26 RRDsProcessed:
代表抓取成功了
注意RRA目录下面的文件都是每隔1分钟产的数据才算成功。
