nginx服务启动程序的Shell脚本怎么写

使用源码包安装的Nginx没办法使用"service nginx start"或"/etc/init.d/nginx start"进行操作和控制，所以写了以下的服务控制脚本。

选项有：

  start    启动  stop    停止  reload   重载  restart    重启  status   状态  test    检查配置文件

脚本一

创建脚本文件并添加执行权限

  touch /etc/init.d/nginx  chmod +x /etc/init.d/nginx

编写脚本内容

  #!/bin/bash  # chkconfig: - 85 15  # description: Nginx server control script  # processname: nginx  # config file: /usr/local/nginx/conf/nginx.conf  # pid file: /usr/local/nginx/logs/nginx.pid  #  # eastmoney public tools  # version: v1.0.0  # create by XuHoo, 2016-9-14  #  # source function library  . /etc/rc.d/init.d/functions  NGINX_NAME="nginx"  NGINX_PROG="/usr/local/sbin/nginx"  NGINX_PID_FILE="/usr/local/nginx/logs/nginx.pid"  NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"  NGINX_LOCK_FILE="/var/lock/subsys/nginx.lock"  # check current user  [ "$USER" != "root" ] && exit 1  start() {  status  if [[ $? -eq 0 ]]; then  echo $"Nginx (PID $(cat $NGINX_PID_FILE)) already started."  return 1  fi  echo -n $"Starting $NGINX_NAME: "  daemon $NGINX_PROG -c $NGINX_CONF_FILE  retval=$?  echo  [ $retval -eq 0 ] && touch $NGINX_LOCK_FILE  return $retval  }  stop() {  status  if [[ $? -eq 1 ]]; then  echo "Nginx server already stopped."  return 1  fi  echo -n $"Stoping $NGINX_NAME: "  killproc $NGINX_PROG  retval=$?  echo  [ $retval -eq 0 ] && rm -f $NGINX_LOCK_FILE  return $retval  }  restart() {  stop  sleep 1  start  retval=$?  return $retval  }  reload() {  echo -n $"Reloading $NGINX_NAME: "  killproc $NGINX_PROG -HUP  retval=$?  echo  return $retval  }  status() {  netstat -anpt | grep "/nginx" | awk '{print $6}' &> /dev/null  if [[ $? -eq 0 ]]; then  if [[ -f $NGINX_LOCK_FILE ]]; then  return 0  else  return 1  fi  fi  return 1  }  _status() {  status  if [[ $? -eq 0 ]]; then  state=`netstat -anpt | grep "/nginx" | awk '{ print $6 }'`  echo $"Nginx server status is: $state"  else  echo "Nginx server is not running"  fi  }  test() {  $NGINX_PROG -t -c $NGINX_CONF_FILE  retval=$?  return $retval  }  case "$1" in  start)  start  ;;  stop)  stop  ;;  reload)  reload  ;;  restart)  restart  ;;  status)  _status  ;;  test)  test  ;;  *)  echo "Usage: { start | stop | reload | restart | status | test }"  exit 1  esac

将脚本添加到系统服务并设置开机启动

  chkconfig --add nginx  chkconfig --level 3 nginx on

脚本二

  [root@localhost ~]# cd /usr/local/nginx/conf/  [root@localhost conf]# ls  fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf  fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default

备份主配置文件

  [root@localhost conf]# cp nginx.conf nginx.conf.origin  [root@localhost conf]# vim nginx.conf  去除#pid logs/nginx.pid;前面#号  [root@localhost conf]# netstat -anpt | grep 80  tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 19108/nginx  [root@localhost conf]# kill -3 19108  [root@localhost conf]# netstat -anpt | grep 80  [root@localhost conf]# nginx  [root@localhost conf]# netstat -anpt | grep 80  tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 19864/nginx  [root@localhost conf]# cd ../logs/  [root@localhost logs]# ls  access.log error.log nginx.pid  [root@localhost logs]# cat nginx.pid  19864

编辑写服务脚本

  [root@localhost ~]# vim /etc/init.d/nginx  可以使用的选项有：  start    启动  stop    停止  reload   重载  restart    重启  status   状态  test    检查配置文件  #!/bin/bash  #chkconfig: 2345 99 20  #description:Nginx Server Control Scripts shell  PROG="/usr/local/nginx/sbin/nginx"  PIDF="/usr/local/nginx/logs/nginx.pid"  case "$1" in  start)  if [ -f $PIDF ];  then  echo "Nginx正在运行…"  else  $PROG  fi  ;;  stop)  if [ -f $PIDF ];  then  kill -3 $(cat $PIDF)  rm -f $PIDF  else  echo "Nginx正在停止…"  fi  ;;  restart)  $0 stop  $0 start  ;;  reload)  if [ -f $PIDF ];  then  kill -1 $(cat $PIDF)  else  echo "Nginx正在停止…重新加载"  fi  ;;  status)  if [ -f $PIDF ];  then  echo "Nginx正在运行"  else  echo "Nginx停止"  fi  ;;  *)  echo "Usage: $0 (start|stop|restart|reload|status)"  exit 1  esac  exit 0

脚本文件并添加执行权限

  [root@localhost ~]# chmod +x /etc/init.d/nginx   将脚本添加到系统服务并设置开机启动  [root@localhost ~]# chkconfig --add nginx  添加为服务启动项  [root@localhost ~]# chkconfig --list nginx  nginx 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭  [root@localhost ~]# chkconfig --level 3 nginx on  测试脚本是否能够执行  [root@localhost ~]# service nginx start  Nginx正在运行…  [root@localhost ~]# service nginx restart  [root@localhost ~]# service nginx stop  [root@localhost ~]# service nginx stop  Nginx正在停止…  [root@localhost ~]# service nginx start  [root@localhost ~]# service nginx status  Nginx正在运行
