cacti + nagios + pnp +npc
Centos6.2一、安装环境LAMP
#yum -y install gcc* glibc* gd* php* mysql* http*
#yum -y install httpdmysql-server mysql-devel perl-DBI perl-DBD-MySQL php php-devel php-mysql php-snmp php-pdophp-gd lm_sensors net-snmp net-snmp-libs net-snmp-utils net-snmp-devel
# chkconfig mysqld on
# chkconfig httpd on
# chkconfig snmpd on
# service mysqld start
# service httpd start
# service snmpd start
#vim /var/www/html/index.php
访问http://localhost/index.php

# mysqladmin -u root password '123'
报错处理: # exportPATH=$PATH:/usr/local/mysql/bin
# mysql -u root -p
输入密码
mysql>create database cacti default character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql>grant all on cacti.* to cacti@localhost identified by '123';
Query OK, 0 rows affected (0.01 sec)
mysql>flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> \q
二、安装cacti
安装rrdtool需要的软件包
# yum -y install cairo-devel libxml2-devel pango pango-devel
安装rrdtool
# tar zxvf rrdtool-1.4.4.tar.gz
# cd rrdtool-1.4.4
# ./configure --prefix=/usr/local/rrdtool && make && make install
# ln -s /usr/local/rrdtool/bin/* /usr/local/bin/ #此步非常重要
安装cacti-0.8.7.e中文版
#wget http://blogimg.chinaunix.net/blog/upfile2/090815172648.gz
# tar zxvf 090815172648.gz -C /var/www/html
# cd /var/www/html
# mv cacti-0.8.7e-cn-utf8/ cacti
# mysql -ucacti -p cacti < cacti/cacti.sql/导入数据库
Enter password:
创建cacti用户
# useradd -s /sbin/nologin cacti
# chown -R cacti:cacti /var/www/html/cacti/
# chmod -R 777 /var/www/html/cacti/
修改cacti配置文件，连接数据库
# vim /var/www/html/cacti/include/config.php
$database_username = "cacti";
$database_password = "123";
添加计划任务
# crontab -e
*/5 * * * * /usr/bin/php/var/www/html/cacti/poller.php >/dev/null 2>&1
# service crond restart
三、被监控端配置
安装snmp服务
#yum -y install lm_sensors net-snmp
修改配置文件如下：（这里我省略掉了#行和空行）
只改了下面三行，（下面的地址是cacti服务器地址，由于是本机测试，所以是127.0.0.1）
#vim /etc/snmp/snmpd.conf
41 com2sec notConfigUser 127.0.0.1 public
62 access notConfigGroup "" any noauth exact all none none
85 view all included .1 80 将前面#号去掉
重启服务
# service httpd restart
# service mysqld restart
# service snmpd restart
检测在服务器上，有信息返回说名正常：
#snmpwalk -c public -v 2c localhost
# snmpwalk -v 1 -c public localhostIP-MIB::ipAdEntIfIndex
浏览器输入http://192.168.163.143/cacti/install初始化cacti，最后如下：
如果打开网页，页面出现空白，那么说明数据库没有导入进去，重新导入数据库后重启httpd服务即可
RRDTOOLS版本，默认为1.0.x，改为1.3.x就行了

如果打开未看到生成图像，请手动执行下面命令
#/usr/bin/php/var/www/cacti/poller.php &>/dev/null手动生成图像

字体在图形中显示不正常的解决方法
下载并安装中文字体，我用的是微米黑字体
wget http://sourceforge.net/projects/wqy/files/wqy-microhei/0.2.0-beta/wqy-microhei-0.2.0-beta.tar.gz
#tar zxvf wqy-microhei-0.2.0-beta.tar.gz
# cd wqy-microhei
# cp wqy-microhei.ttc /usr/share/fonts/wqy-microhei.ttc
安装完成后注意在"设置"中更改下面两个必改项.
常规->RRDTool应用程序版本改为1.3.x,默认为1.0.x.不改可能图像不能正常显示出来.
路径->RRDTool默认字体路径改为上面安装的文件路径，如/usr/share/fonts/wqy-microhei.ttc
安装插件cacti-plugin
#wget http://blogimg.chinaunix.net/blog/upfile2/090818213852.gz
# mv 090818213852.gz cacti-plugin-0.8.7d-PA-v2.4-cn-utf8.diff.gz
# gunzip cacti-plugin-0.8.7d-PA-v2.4-cn-utf8.diff.gz
# mv cacti-plugin-0.8.7d-PA-v2.4-cn-utf8.diff /var/www/html/cacti/
# cd /var/www/html/cacti/
# patch -p1 -N
