shell编写nginx服务启动脚本

作者: admin 分类: shell 发布时间: 2018-07-12 13:14

  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
