nginx -s reload

This command sends a signal to the Nginx server process to reload its configuration file without stopping and restarting the server. This is useful when you have made changes to the configuration file and want to apply them without disrupting the server's operation. The "reload" signal instructs Nginx to gracefully shut down worker processes and spawn new ones with the updated configuration.

nginx -t是用于检查nginx配置文件语法是否正确的命令。当我们修改了nginx的配置文件后,可以使用nginx -t命令来验证配置文件的正确性,以避免在重启nginx时出现错误。
nginx -s reload是用于重新加载nginx配置文件的命令。当我们修改了nginx的配置文件后,可以使用nginx -s reload命令来重新加载配置文件,使新的配置生效,而无需重启整个nginx服务。
nginx -s reload原理
回答: 当我们执行nginx -s reload命令时,nginx会向其master进程发送SIGHUP信号,这会触发master进程重新加载配置文件。在重新加载配置文件的过程中,nginx会启动新的worker进程,并逐渐停止旧的worker进程。这样就实现了新老请求的平滑过渡。具体来说,当master进程接收到SIGHUP信号后,它会首先解析新的配置文件,并检查语法错误。如果没有错误,master进程会启动新的worker进程,并向旧的worker进程发送SIGQUIT信号,通知它们停止接收新的请求并处理完当前的请求。新的worker进程会逐渐接管旧的worker进程的工作,直到所有旧的worker进程都停止运行。这样就实现了nginx的平滑升级。\[3\]
