1、CactiEz 重启后，访问面页显示空白页面

解决办法：service httpd restart  apache重启后，并加入到开机启动中。chkconfig httpd on 或者 vim /etc/rc.local 加入 /etc/init.d/httpd start | restart

2、检查mysql状态，正常状态

3、后来重新刷新，无法进入界面。网上查找说是日志文件把空间占满。（当空间占满，服务运行没有空间支撑）当时df -h  磁盘已被打满，查看到cacti.log单文件14G，另外./var/log/mysqld.log 单个文件为3G

[root@cactiez /]# cd /var/www/html/log

[root@cactiez log]# ls

cacti.log

cacti.log-20170511  cacti.log-20170513  cacti.log-20170515  cacti.log.bak-20170516

cacti.log-20170510  cacti.log-20170512  cacti.log-20170514  cacti.log-20170516

#日志用于排错，所以要备份部分日志文件。

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

cat /dev/null > mysqld.log

cat /dev/null > cacti.log

完事后查看空间，可以重新进入cacti可以

4、可以正常登陆访问后，但是cacti不画图，无流量。经查cacti.log的日志，是mysqlcacti表存在问题，按下方式进入 mysql进行修复，然后等待一分钟时间，cacti画图恢复。

[root@cactiez log]# tail /var/www/html/log/cacti.log.bak-20170516
