最近从GOOGLE ananlytics 发现网站速度变慢了很多, 于是想到了PHP中的FPM慢日志功能。
好在 PHP-FPM 提供了慢执行日志,可以将执行比较慢的脚本的调用过程 dump 到日志中。
cd /etc/php5/fpm/pool.d/
vi www.conf
修改配置

我们经常会从服务器A传文件到服务器B, 但有时候用PUTTY执行命令的时候, 文件传了一部分, PUTTY终端就关闭了, 这时候文件也没传完整。
这里有一个解决把办法,让SCP命令在后台执行。
用nohup命令
$nohup scp file_to_copy user@server:/path/to/copy/the/file > nohup.out 2>&1
这时候还不是在后台运行,你需要输入密码,
接着按ctr+z去暂停命令,
然后用bg命令
bg
这个时候, 即使你关闭PUTTY, SCP还是在后台运行, 直到完成。
