cd cacti-spine-1.1.2
./bootstrap
./configure
make
make install
chown root:root /usr/local/spine/bin/spine
chmod +s /usr/local/spine/bin/spine
cd /usr/local/spine/etc
cp spine.conf.dist spine.conf
編輯spine.conf
修改數(shù)據(jù)庫相關(guān)的用戶名和密碼
安裝cacti
安裝源碼
tar zxvf cacti-1.1.2.tar.gz
mv cacti-1.1.2 /var/www/html/cacti
chown -R nginx:nginx /var/www/html/cacti
編輯config.php
cd /var/www/html/cacti/include/
cp config.php.dist config.php
修改數(shù)據(jù)相關(guān)的用戶名和密碼
導(dǎo)入sql
mysql -uroot -p
MariaDB [(none)]> create database cacti;
MariaDB [(none)]> grant all on *.* to cactiuser@localhost identified by "cactipass";
MariaDB [(none)]> flush privileges;
mysql -u cactiuser -p cacti < /var/www/html/cacti/cacti.sql
數(shù)據(jù)庫名稱:cacti
用戶名:cactiuser
數(shù)據(jù)庫密碼:cactipass
確認web和db服務(wù)都已啟動，使用下面命令啟動
systemctl start mariadb.service
systemctl start nginx.service
systemctl start php-fpm.service
這3個進程都要啟動
配置cacti
添加crontab任務(wù)
vim /etc/cron.d/cacti
*/1 * * * * nginx /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1
注意是使用nginx用戶運行crontab
