安装

yum install -y epel-release
yum install -y nginx php-fpm mariadb-server mariadb php php-mysql php-gd php-xml php-mbstring php-snmp net-snmp net-snmp-utils rrdtool rrdtool-devel certbot python3-certbot-nginx wget mariadb-devel net-snmp-devel  php-gmp php-intl php-ldap php-posix

启动服务

systemctl enable --now nginx php-fpm mariadb 

下载并解压cacti ，并更改权限

# 目前版本为cacti-1.2.29
cd /var/www/html
wget https://www.cacti.net/downloads/cacti-latest.tar.gz
tar -zxvf cacti-latest.tar.gz
mv cacti-1.2.29/ cacti 
chown -R apache:apache /var/www/html/cacti/

创建数据库，并导入初始数据

mysql   #进入数据库
#下面命令在数据库中执行 
CREATE DATABASE cacti;
GRANT ALL PRIVILEGES ON cacti.* TO 'cactiuser'@'localhost' IDENTIFIED BY 'cactiuser';
FLUSH PRIVILEGES;
EXIT;

# 导入cacti 初始化数据 
mysql -u cactiuser -p cacti < /var/www/html/cacti/cacti.sql

# 配置 Cacti 数据库连接
vi /var/www/html/cacti/include/config.php
里面配置不用改，我们是默认帐号和密码初始化的数据库

配置nginx

cat > /etc/nginx/conf.d/cacti.conf 
server {
    listen 80;
    server_name your-domain.com;

    root /var/www/html/;
    index index.php;

    location / {
        try_files $uri $uri/ index.php;
    }

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~ /\.ht {
        deny all;
    }
}

重启 Nginx 和 PHP-FPM

systemctl restart nginx php-fpm

开放端口

sed -i s@=enforcing@=disabled@ /etc/selinux/config
setenforce 0
firewall-cmd --add-port 80/tcp
firewall-cmd --add-port 80/tcp --permanent

导入时区

timedatectl set-timezone Asia/Shanghai
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql


mysql # 进入数据库 
GRANT SELECT ON mysql.time_zone_name TO 'cactiuser'@'localhost';
FLUSH PRIVILEGES;

安装spine

 yum -y install libtool automake help2man

wget https://files.cacti.net/spine/cacti-spine-1.2.29.tar.gz
cd cacti-spine-1.2.29/
./bootstrap
./configure
 make
make install
chown root:root /usr/local/spine/bin/spine
chmod u+s /usr/local/spine/bin/spine
cd /usr/local/spine/etc/
cp spine.conf.dist  spine.conf

初始化

http://127.0.0.1/cacti
默认帐号 密码 admin/admin 。登陆进去后会强制修改密码

如上图，会有一堆的配置不满足，逐个修改

cat /etc/php.ini |grep date.time
; http://php.net/date.timezone
;date.timezone =
date.timezone = Asia/Shanghai
memory_limit = 1280M
max_execution_time = 80

yum -y install php-gmp php-intl php-ldap php-posix
