Nginx的各种简单配置（一）

记录一下Nginx下各种简单实用的配置方法
一、Nginx服务启动脚本
Nginx服务还没有启动脚本，每次都用/usr/local/nginx/conf/nginx来控制，略显麻烦找了一个shell脚本.
Code：

#!/bin/bash
# chkconfig: - 30 21          ## 30表示开机启动顺序，21表示关机顺序， - 表示服务启动的运行级别：2、3、4、5，排除0、1、6
# description: http service.  ## 服务描述信息
# Source Function Library     ## 源函数库，/etc/init.d/下的服务脚本都需要这么写（应该是吧）

. /etc/init.d/functions       ## 加载全局库函数，不写不行喔～

NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"

start() {
	echo -n $"Starting $prog:"
	mkdir -p /dev/shm/nginx_temp
	daemon $NGINX_SBIN -c $NGINX_CONF
	RETVAL=$?
	echo
	return $RETVAL
}

stop() {
	echo -n $"Stoping $prog:"
	killproc -p $NGINX_PID $NGINX_SBIN -TERM
	rm -rf /dev/shm/nginx_temp
	RETVAL=$?
	echo
	return $RETVAL
}

reload() {
	echo -n $"Reloading $prog:"
	killproc -p $NGINX_PID $NGINX_SBIN -HUP
	RETVAL=$?
	echo
	return $RETVAL
}

restart() {
	stop
	start
}

configtest() {
	$NGINX_SBIN -c $NGINX_CONF -t
	return 0
}

case "$1" in
	start)
		start
		;;
	stop)
		stop
		;;
	reload)
		reload
		;;
	restart)
		restart
		;;
	configtest)
		configtest
		;;
	*)
		echo $"Usage: $0 {start|stop|reload|restart|configtest|}"
		RETVAL=1
esac

exit $RETVAL

Terminal Command：

chmod 755 /etc/init.d/nginx       ## 更改权限
chkconfig --add nginx             ## 添加到服务
chkconfig nginx on                ## 开机启动

官方的自带的，用yum安装才有
