shell语句编写nginx的启动脚本

nginx的启动脚本
问题：在预编译安装nginx时候每次启动时都非常不方便，所以想了下写个nginx脚本在/etc/init.d目录下可实现service的方式启动、停止、重启这样就方便多了！ [root@cml init.d]# vim nginxd#!/bin/bash#chkconfig: 2345 20 80
prog="nginxd"nginx_bin="/usr/local/nginx/sbin/nginx" if [ -x $nginx_bin ]; then ##if语句判断是否存在nginx路径 echo "$nginx_bin is installled !" else echo -n "$nginx_bin not installed !" exit 5fi start(){ echo -n "starting $prog:" $nginx_bin -t ##测试nginx配置文件 a=$? if [ $a -eq 0 ]; then ###if语句判断上一句是否执行成功 touch /tmp/nginx.pid ##创建一个nginx.pid文件后启动nginx $nginx_bin else echo "please check your nginx config" exit 10 fi} stop(){ echo -n $"stopping $prog:" $nginx_bin -s stop ##停止nginx a=$? if [ $a -eq 0 ]; then ##判断执行上一句成功就删除nginx.pid文件输出信息 rm -rf /tmp/nginx.pid echo "success stop nginx" else echo "check your nginx command" exit 11 fi} case $1 in ## start) start;; stop) stop;; reload|restart) stopsleep 2start;; *) echo "Usage:$0{start|stop|reload/restart}" ;;esac 验证：
