test

/usr/local/spine/bin/spine

Next configure the cacti graphical tool (installed by default in/usr/local/spine/sbin/spine, linked to/sbin/spine):

Console -> Configureation -> Settings -> Alternate Poller Path -> Spine Poller File Path

Console -> Cacti Settings -> Poller -> Poller Type

Then modify the scheduled tasks from once every 5 minutes to once every minute

/5 php /opt/cacti/cacti/poller.php > /dev/null 2>&1

changed to

/1 php /opt/cacti/cacti/poller.php > /dev/null 2>&1

service httpd restartservice mysqld restartservice snmpd restart

13. complete the installation

http://localhost/cacti

troubleshooting

1. No pictures:

/var/www/html/cacti

Directory empowerment 777, wait 5 minutes for polling.

2. Not shown yet:

mysqluse cacti;select count(*) from polleroutput; truncate table polleroutput;select count(*) from polleroutput;

Finally rebuild the cache.

3. Change to Chinese support

--Change rrdtool version number to 1.2.x;

--Copy the font file MSYH.ttf into/usr/share/fonts/and authorize 777;

--cacti page, change default font path to/usr/share/fonts/MSYH.ttf;

--Modify vim/var/www/html/cacti/lib/functions.php to add:

setlocale(LCCTYPE,"zhCN.UTF-8");

Restart the httpd service.

Attached:

For example, the cacti platform requires changing the default port number (e.g., 10010) and making whitelist restrictions (e.g., only allowing IP address 123.123.123.123 to log in). The relevant settings are as follows

1. Change port number

vim /etc/httpd/conf/httpd.conf

Change Listen:80 to Listen:10010 under line 137, save exit.

2. Firewall releases port number 10010

vim /etc/sysconfig/iptables

add firewall rules

-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

Restart firewall services

service iptables restart

3. Whitelist access restrictions

vim /etc/httpd/conf/httpd.conf

Under line 318, add the following and save exit

Order allow,denyAllow from 123.123.123.123

Restart httpd service

service httpd restart
