CentOS7 安装 Cacti1.1.26

Posted 2021-02-16

注：最新版本的cacti对于LAMP的要求更高，特别是mysql数据库的要求，多方尝试发现用10版本以上的mariadb是最简单的。

1.安装LAMP架构

由于系统自带的是MariaDB5.5需要卸载
[[email protected] ~]# rpm -qa mariadb-libs-5.5.60

[[email protected] ~]# 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

[[email protected] yum.repos.d]# yum clean all && yum makecache

[[email protected] yum.repos.d]#

yum install httpd MariaDB-client MariaDB-server MariaDB-devel php-snmp php-ldap php-pdo php-mysql php-devel php-pear php-common php-gd php-mbstring php-xml php-process net-snmp net-snmp-utils net-snmp-libs net-snmp-agent-libs net-snmp-devel rrdtool rrdtool-php rrdtool-perl rrdtool-devel gcc openssl-devel dos2unix autoconf automake binutils libtool cpp postfix glibc-headers kernel-headers glibc-devel gd gd-devel help2man ntpdate wget patch

-----------安装cacti-spine优化数据轮询速度-----
新版的cacti可以不使用php脚本去采集数据，新集成了一个插件spine用于采集数据
