: > port 80被占用了, 可以用sockstat看是哪只程式占用的.
: 我看的结果是
: nobody httpd 532 3 tcp4 210.241.xxx.xxx:80 *:*
: nobody httpd 531 3 tcp4 210.241.xxx.xxx:80 *:*
: nobody httpd 530 3 tcp4 210.241.xxx.xxx:80 *:*
: nobody httpd 529 3 tcp4 210.241.xxx.xxx:80 *:*
: nobody httpd 528 3 tcp4 210.241.xxx.xxx:80 *:*
: root httpd 510 3 tcp4 210.241.xxx.xxx:80 *:*
: 怎麽会 httpd 有用 root 执行，也有用 nobody 执行那麽多个呢 ?
Only root can bind the ports below 1024, therefore the first httpd
must have root privilege. After httpd binds port 80, it sets uid to
nobody and pre-forks several processes to accelerate the handling
of incoming connections.
