10、问题汇总
问题1：
Warning: strtotime(): It is not safe to rely on the system‘s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone ‘UTC‘ for now, but please set date.timezone to select your timezone. in /usr/local/apache2/htdocs/cacti/include/global_constants.php on line 165
解决方法：
# vim /usr/local/php/lib/php.ini
修改
date.timezone = PRC
并取消注释
问题2：
PHP Strict Standards: Only variables should be passed by reference in /usr/local/nginx/html/cacti/lib/ping.php on line 382
解决方法：
socket_select($r = array($this->socket), $w = NULL, $f = NULL, $to_sec, $to_usec){
=>修改为
$r = array($this->socket);
$w = NULL;
$f = NULL;
switch(socket_select($r, $w, $f, $to_sec, $to_usec)){
问题3：
WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is ‘300‘ seconds, with a maximum of a ‘300‘ second Cron, but 2135 seconds have passed since the last poll!
解决方法：
*/1 * * * * /usr/bin/php /usr/local/apache2/htdocs/cacti/poller.php > /dev/null 2>&1
