3.安装配置 Cacti 
3.1 下载解压 Cacti 安装包 
useradd -r -M cacticd /var/www/html/wget https://github.com/Cacti/cacti/archive/release/1.1.38.tar.gztar -zxvf 1.1.38.tar.gzcp -R cacti-release-1.1.38/ /var/www/html/cacticd /var/www/html/cacti3.2 创建 cacti 数据库，创建 cactiuser 用户，设置相关授权 
mysql -u root -pCREATE database cacti default character set utf8;create user 'cacti'@'localhost' identified by 'xxx3';grant all privileges on cacti.* to cacti@localhost;grant select on mysql.time_zone_name to 'cacti'@'localhost' identified by 'xxx3';flush privileges;3.3 导入 Cacti 默认数据库 
use cacti;source /var/www/html/cacti/cacti.sql;flush privileges;quit3.4 编辑 /var/www/html/cacti/include/config.php 
$database_type = "mysql";$database_default = "cacti";$database_hostname = "localhost";$database_username = "cacti";$database_password = "xxx3"/* load up old style plugins here */$plugins = array();//$plugins[] = 'thold';3.5 创建 cacti 系统用户，设置 graph/log 目录权限 
chown -R apache.apache /var/www/html/chown -R cacti  /var/www/html/chown -R apache.apache /var/www/html/cacti/chown -R cacti /var/www/html/cacti/{rra,log}/chmod -R 777 /var/www/html/cacti/{rra,log}/3.6 添加定时任务 
crontab -e*/1 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&14.配置防火墙 
4.1 配置 firewalld 防火墙 
firewall-cmd --permanent --add-port=3306/tcpfirewall-cmd --permanent --add-service=httpfirewall-cmd --permanent --add-port=161/udpfirewall-cmd  --permanent --add-port=162/udpfirewall-cmd --reload4.2 关闭selinux 
setenforce 0sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config5.安装 spine 
5.1 下载解压与 Cacti 相同版本号 Spine 源码安装包 
cd /usr/local/srcwget http://www.cacti.net/downloads/spine/cacti-spine-1.1.38.tar.gztar xf cacti-spine-1.1.38.tar.gz5.2 源码编译安装 spine 
ln -s /usr/lib64/libmysqlclient.so.18.0.0 /usr/lib64/libmysqlclient.sontpdate ntp.sjtu.edu.cncd cacti-spine-1.1.38./configure && make && make install5.3 复制修改配置文件 
cp /usr/local/spine/etc/spine.conf.dist /etc/spine.confvim /etc/spine.confDB_Host                 localhostDB_Database             cactiDB_User                 cactiDB_Pass                 xxx3DB_Port                 3306RDB_Host                localhostRDB_Database            cactiRDB_User                cactiRDB_Pass                xxx3RDB_Port                33065.4 测试 
/usr/local/spine/bin/spine 将会出现以下结果 
SPINE: Using spine config file [/etc/spine.conf] 
SPINE: Version 1.1.38 starting 
SPINE: Time: 0.0429 s, Threads: 5, Devices: 0 
6.设置重启、开机启动相关服务 
systemctl restart httpdsystemctl restart mariadbsystemctl restart crondsystemctl restart snmpdsystemctl enable httpdsystemctl enable mariadbsystemctl enable crondsystemctl enable snmpd7.登录 Cacti WEB 页面修改 Cacti 配置 
Console -> 设置（Cacti Settings） -> Paths -> 在 Spine Binary File Location 文本框内填入配置文件路径 /usr/local/spine/bin/spine ，在 Spine Config File Path 框内填入配置文件路径 /usr/local/spine/etc/spine.conf，点击保存 （Save）。 
Console -> 设置（Cacti Settings） -> Poller -> 在 Poller Type 下拉框中选择 spine ，点击保存 （Save）。 
8.特别提示 
在添加完设备和图形后，需要重建采集器缓存。 
Console –> 系统工具 –> Rebuild Poller Cache 
附： 
比如说cacti平台要求更改默认端口号（例改为10010），且做白名单限制（例只允许IP地址123.123.123.123登录），相关设置如下 
1、改端口号 
vim /etc/httpd/conf/httpd.conf 
在第137行下修改Listen:80为Listen:10010，保存退出。 
2、防火墙放行10010端口号 
vim /etc/sysconfig/iptables 
添加防火墙规则 
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10010 -j ACCEPT 
重启防火墙服务 
service iptables restart 
3、做白名单访问限制 
vim /etc/httpd/conf/httpd.conf 
在第318行下， <Directory "/var/www/html">内添加如下内容并保存退出 
Order allow,deny 
Allow from 123.123.123.123 
重启httpd服务 
service httpd restart
