linux 下nginx

所有的配置文件都在/etc/nginx                   (ect/nginx/nginx.conf)

下，并且每个虚拟主机已经安排在

了/etc/nginx/sites-available

程序文件在/usr/sbin/nginx 

日志放在了/var/log/nginx中

并已经在/etc/init.d/下创建了启动脚本

nginx

-----------------------控制命令---------------------

$ sudo service nginx quit
Usage: nginx {start|stop|restart|reload|force-reload|status|configtest|rotate|upgrade}

或者：

sudo nginx -s stop    （停止）

sudo nginx -s reload  (加载最新配置)

sudo nginx -s quit    （优雅停止）

sudo nginx -s reopen   （重新打开日志）

sudo nginx -t           （测试配置是否正确）

-------------------------------------------------------------

--------------------------日志文件的备份与重定向----------------------------

将某个log的日志文件mv到.bak文件,

再次为nginx touch一个新的日志文件,此时需要重启nginx 或使用sudo nginx -s reopen命令
