我将max_execution_time设置为120秒。
$ grep max_execution_time /etc/php5/php.ini
max_execution_time = 120
我仍然得到错误
Error: Maximum execution time of 60 seconds exceeded
在几次重新加载后，它会工作(可能是在编译Twig和LESS以缓存(，但通常会失败，尤其是在新页面或运行composer之后。
我没有看到任何地方通过代码设置(更低(：
$ grep -r max_execution_time *
vendor/symfony/symfony/appveyor.yml: - echo max_execution_time=1200 >> php.ini-min
web/classes/phpmailer/class.smtp.php: $max = ini_get('max_execution_time');
web/conf/phpini.inc.php: ini_set("max_execution_time", "3600");
web/simplesaml/modules/statistics/config-templates/module_statistics.php: * Set max running time for this script. This is also controlle by max_execution_time in php.ini
我还尝试添加opcache来加快速度，但似乎并没有更快。
$ grep opcache composer.json
"ext-opcache": "*",
$ cat /etc/php5/conf.d/opcache.ini
zend_extension = /usr/lib/php/20131226/opcache.dll

我添加了
ini_set("max_execution_time", 120);
在CCD_ 4做任何事情之前。
如上文评论中所述。
