利用BashShell编写Nginx服务控制脚本

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。

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

1、创建脚本文件并添加执行权限

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

2、编写脚本内容

  1 #!/bin/bash
  2 # chkconfig: - 85 15
  3 # description: Nginx server control script
  4 # processname: nginx
  5 # config file: /usr/local/nginx/conf/nginx.conf
  6 # pid file: /usr/local/nginx/logs/nginx.pid
  7 #
  8 # eastmoney public tools
  9 # version: v1.0.0
 10 # create by XuHoo, 2016-9-14
 11 #
 12
 13 # source function library
 14 . /etc/rc.d/init.d/functions

 16 NGINX_NAME="nginx"
 17 NGINX_PROG="/usr/local/sbin/nginx"
 18 NGINX_PID_FILE="/usr/local/nginx/logs/nginx.pid"
 19 NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
 20 NGINX_LOCK_FILE="/var/lock/subsys/nginx.lock"
 21
 22 # check current user
 23 [ "$USER" != "root" ] && exit 1
 24
 25 start() {
 26     status
 27         if [[ $? -eq 0 ]]; then
 28             echo $"Nginx (PID $(cat $NGINX_PID_FILE)) already started."
 29             return 1
 30         fi
 31     echo -n $"Starting $NGINX_NAME: "
 32         daemon $NGINX_PROG -c $NGINX_CONF_FILE
 33         retval=$?
 34         echo
 35     [ $retval -eq 0 ] && touch $NGINX_LOCK_FILE
 36     return $retval
 37 }
 38
 39 stop() {
 40     status
 41         if [[ $? -eq 1 ]]; then
 42             echo "Nginx server already stopped."
 43             return 1
 44         fi
 45     echo -n $"Stoping $NGINX_NAME: "
 46         killproc $NGINX_PROG
 47         retval=$?
 48         echo
 49     [ $retval -eq 0 ] && rm -f $NGINX_LOCK_FILE
 50     return $retval
 51 }
 52
 53 restart() {
 54     stop
 55         sleep 1
 56     start
 57     retval=$?
 58     return $retval
 59 }
 60
 61 reload() {
 62     echo -n $"Reloading $NGINX_NAME: "
 63         killproc $NGINX_PROG -HUP
 64         retval=$?
 65         echo
 66     return $retval
 67 }
 68
 69 status() {
 70     netstat -anpt | grep "/nginx" | awk ‘{print $6}‘ &> /dev/null
 71         if [[ $? -eq 0 ]]; then
 72             if [[ -f $NGINX_LOCK_FILE ]]; then
 73                 return 0
 74             else
 75                 return 1
 76             fi
 77         fi
 78     return 1
 79 }
 80
 81 _status() {
 82     status
 83         if [[ $? -eq 0 ]]; then
 84             state=`netstat -anpt | grep "/nginx" | awk ‘{ print $6 }‘`
 85             echo $"Nginx server status is: $state"
 86         else
 87             echo "Nginx server is not running"
 88         fi
 89 }
 90
 91 test() {
 92     $NGINX_PROG -t -c $NGINX_CONF_FILE
 93         retval=$?
 94     return $retval
 95 }
 96
 97 case "$1" in
 98     start)
 99         start
100         ;;
101     stop)
102         stop
103         ;;
104     reload)
105         reload
106         ;;
107     restart)
108         restart
109         ;;
110     status)
111         _status
112         ;;
113     test)
114         test
115         ;;
116     *)
117         echo "Usage: { start | stop | reload | restart | status | test }"
118         exit 1

3、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

4、测试脚本是否能够执行

运行命令： service nginx start 或 /etc/init.d/nginx start
