6.設(shè)置重啟、開機啟動相關(guān)服務(wù)?
systemctl restart httpdsystemctl restart mariadbsystemctl restart crondsystemctl restart snmpdsystemctl enable httpdsystemctl enable mariadbsystemctl enable crondsystemctl enable snmpd7.登錄?Cacti WEB?頁面修改?Cacti?配置?
Console ->?設(shè)置（Cacti Settings）?-> Paths ->?在?Spine Binary File Location?文本框內(nèi)填入配置文件路徑?/usr/local/spine/bin/spine?，在?Spine Config File Path?框內(nèi)填入配置文件路徑?/usr/local/spine/etc/spine.conf，點擊保存 （Save）。?
Console ->?設(shè)置（Cacti Settings）?-> Poller ->?在?Poller Type?下拉框中選擇?spine?，點擊保存 （Save）。?
8.特別提示?
在添加完設(shè)備和圖形后，需要重建采集器緩存。?
Console –>?系統(tǒng)工具?–> Rebuild Poller Cache?
附：?
比如說cacti平臺要求更改默認端口號（例改為10010），且做白名單限制（例只允許IP地址123.123.123.123登錄），相關(guān)設(shè)置如下?
1、改端口號?
vim /etc/httpd/conf/httpd.conf?
在第137行下修改Listen:80為Listen:10010，保存退出。?
2、防火墻放行10010端口號?
vim /etc/sysconfig/iptables?
添加防火墻規(guī)則?
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10010 -j ACCEPT?
重啟防火墻服務(wù)?
service iptables restart?
3、做白名單訪問限制?
vim /etc/httpd/conf/httpd.conf?
在第318行下，?<Directory "/var/www/html">內(nèi)添加如下內(nèi)容并保存退出?
Order allow,deny?
Allow from 123.123.123.123?
重啟httpd服務(wù)?
service httpd restart?
