如何在不重启nginx的情况下使修改生效？

Question

Apache 有一个graceful选项，可以在http.conf不重新启动 Apache 的情况下扫描修改。nginx呢？

Answer 1

使用 nginx -s 重新加载

Answer 2

nginx 支持以下信号：

TERM, INT - Quick shutdown
QUIT - Graceful shutdown
HUP - Configuration reload: Start the new worker processes with a new configuration, Gracefully shutdown the old worker processes
USR1 - Reopen the log files
USR2 - Upgrade Executable on the fly
WINCH - Gracefully shutdown the worker processes

HUP 就是你要找的，所以 sudo kill -HUP pid (nginx pid)

通常nginx的init-script有reload动作，即：

• Linux /etc/init.d/nginx reload
• FreeBSD /usr/local/etc/rc.d/nginx reload
