1. After CactiEz is restarted, the access page displays a blank page.

Solution: after service httpd restart apache is rebooted, add it to boot. Chkconfig httpd on or vim / etc/rc.local join / etc/init.d/httpd start | restart

2. Check the mysql status and normal status.

3. Later refreshed and unable to enter the interface. Online search says that log files fill up space. (when the space is full, there is no space to support the service operation.) at that time, the df-h disk has been filled up. You can see the cacti.log single file 14G. In addition, the. / var/log/mysqld.log single file is 3G.

# logs are used for troubleshooting, so back up some log files.

Tail-n 1000 cacti.log > cacti.log.bak-20170516

Cat / dev/null > mysqld.log

Cat / dev/null > cacti.log

Check the space after you are done, and you can re-enter cacti

4. You can log in and visit normally, but cacti does not draw pictures and has no traffic. After checking the log of cacti.log, there is a problem with the mysqlcacti table. Press the method to enter mysql for repair, and then wait one minute for cacti drawing to recover.
