注：最新版本的cacti對於LAMP的要求更高，特別是mysql數據庫的要求，多方嘗試發現用10版本以上的mariadb是最簡單的。
1.安裝LAMP架構
由於系統自帶的是MariaDB5.5需要卸載
[root@localhost ~]# rpm -qa mariadb-libs-5.5.60
[root@localhost ~]# yum remove mariadb-libs-5.5.60 -y
添加MariaDB、yum源
vim /etc/yum.repos.d/Mariadb.repo
[MariaDB]
name = MariaDB
baseurl = https://mirrors.ustc.edu.cn/mariadb/yum/10.3/centos7-amd64/
gpgkey=https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1[root@localhost yum.repos.d]# yum clean all && yum makecache
[root@localhost yum.repos.d]#

---------下面可以開始安裝cacti--------------
官網網站：https://www.cacti.net
[root@localhost ~]# wget https://www.cacti.net/downloads/cacti-1.1.26.tar.gz
[root@localhost ~]# wget https://www.cacti.net/downloads/spine/cacti-spine-1.1.26.tar.gz
[root@localhost~]# tar xf cacti-1.1.26.tar.gz
[root@localhost~]# mv cacti-1.1.26 /var/www/html/cacti
[root@localhost html]# chown -R root.root cacti/
[root@localhost~]# mysql -uroot -p cacti < /var/www/html/cacti/cacti.sql
Enter password: //密碼爲admin123，將cacti的數據庫導入
[root@localhost~]# mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -uroot mysql -p
Enter password: //密碼爲admin123，1.1.26版本的cacti需要導入時間數據庫
[root@localhost~]# mysql -uroot –p //爲cacti用戶賦予時間數據庫的權限
MariaDB [(none)]> grant select on mysql.time_zone_name to 'cacti'@'localhost' IDENTIFIED BY 'admin123';
MariaDB [(none)]> flush privileges;
[root@localhost~]# vim /var/www/html/cacti/include/config.php

$database_ssl = false;
[root@localhost~]# vim /etc/snmp/snmpd.conf

-----------安裝cacti-spine優化數據輪詢速度-----
新版的cacti可以不使用php腳本去採集數據，新集成了一個插件spine用於採集數據
[root@localhost ~]# ln -s /usr/lib64/libmysqlclient.so.18.0.0 /usr/lib64/libmysqlclient.so
[root@localhost ~]# tar xf cacti-spine-1.1.26.tar.gz
[root@localhost ~]# cd cacti-spine-1.1.26
[root@localhost cacti-spine-1.1.26]# ./configure
[root@localhost cacti-spine-1.1.26]# make -j 2 && make install
[root@localhost ~]# cp /usr/local/spine/etc/spine.conf.dist /usr/local/spine/etc/spine.conf
[root@localhost ~]# vim /usr/local/spine/etc/spine.conf //修改相關參數
