为nginx 配置启动脚本
在/etc/rc.d/init.d/目录下新建文件nginx，添加如下内容
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

esac
然后在赋予该脚本执行权限 chmod +x /etc/rc.d/init.d/nginx
chkconfig –add nginx
chkconfig nginx on
service nginx start 就可以启动nginx了
安装mysql
yum install mysql mysql-server mysql-devel
service mysqld start
chkconfig mysqld on
mysqladmin -u root password "qaz,./"
service mysqld start
yum install php lighttpd-fastcgi php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy php-common php-devel php-fpm

重启nginx php-fpm
service nginx restart
service php-fpm restart
在/data0/www/ 下建立phpinfo.php文件，访问测试。
vi phpinfo.php
<?php
phpinfo();
?>
安装配置cacti
yum install net-snmp net-snmp-utils net-snmp-devel rrdtool rrdtool-perl rrdtool-devel
cacti官网下载并解压
tar zxvf cacti-0.8.8b.tar.gz
将文件放到网站目录
mv cacti-0.8.8b /data0/www/cacti
增加cacti用户，用以在该用户下建立执行poller的cron
useradd cacti
将cacti目录下的rra和log目录赋给cacti用户
cd /data0/www/cacti/
chown -R cacti:cacti rra/ log
建立cron
crontab -u cacti -e
cron内容
MAILTO=""
*/5 * * * * /usr/bin/php /data0/www/cacti/poller.php &>/dev/null
登陆http://ip/cacti/进行安装
被监控的linux服务器需要安装net-snmp包（yum即可），安装后更改snmpd.conf文件
vi /etc/snmp/snmpd.conf
更改段：
#       sec.name  source          community
com2sec notConfigUser  58.30.241.221     public
# Make at least  snmpwalk -v 1 localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
view    systemview    included   .1.3.6.1.2.1.1
view    systemview    included   .1.3.6.1.2.1.25.1.1
view    systemview    included   .1
disk / 10000
更改后重启snmpd服务
service snmpd restart
chkconfig snmpd on
被监控的windows服务器需要设置snmp service服务，在安全里建立public社区，设置cacti服务器的ip地址。
如果使用Cacti_SNMP_INFORMANT_STD_W32_Metrics.zip模板，需要在windows服务器上安装informant-std-16.zip（http://www.wtcs.org/informant/download.htm）
模板Cacti_SNMP_INFORMANT_STD_W32_Metrics.zip
解压后10个文件
cacti_data_query_w32_-_cpu_statistics.xml
cacti_data_query_w32_-_network_statistics.xml
cacti_data_query_w32_-_disk_statistics.xml
cacti_data_query_w32_-_object_statistics.xml
cacti_data_query_w32_-_memory_statistics.xml
以上文件在cactit管理界面，Import Templates导入。
snmp_informant_disk.xml
snmp_informant_objects.xml
snmp_informant_memory.xml
snmp_informant_cpu.xml
snmp_informant_network.xml
以上文件copy到服务器cacti安装目录的resource/snmp_queries
登陆cacti地址进行配置。
添加Devices时，SNMP Version最好使用version 2,SNMP Community使用自己定义好的社区（默认和snmpd.conf中的一样是public）
安装spine，安装spine可以提升cacti性能和执行速度，在安装spine之前必须已经安装好了net-snmp net-snmp-devel(之前已经安装过)；使用cmd.php来完成数据采集，发现cmd.php采集存在很大的延迟，执行效率太低。比较了一下，从添加device好到设备up，spine只需要不到一分钟，而cmd等的时间较长。
下载cacti-spine-0.8.8b.tar（与cacti版本对应）
tar xf cacti-spine-0.8.8b.tar
cd cacti-spine-0.8.8b.tar
./configure
make && make install
cd /usr/local/spine/
mv spine.conf.dist spine.conf
配置数据库
vi spine.conf
spine需要将配置文件放在/etc下才能运行，所以建立一个软连接
ln -s /usr/local/spine/etc/spine.conf /etc/spine.conf
测试，运行spine的运行文件
/usr/local/spine/bin/spine
配置cacti使用spine
在setting里配置Spine Poller File Path，spine执行二进制文件默认安装的位置是/usr/local/spine/bin/spine
在poller的Poller Type里将cmd.php更改为spine即可。
