Linux开机自动启动Nginx服务

1.如我博客上篇Nginx安装指南，首先我的执行Nginx路径为：/application/nginx/sbin/nginx；
2.我的Nginx配置文件路径为：/application/nginx/conf/nginx.conf。

下面为nginx服务开机自启动文件，将放在/etc/init.d/目录下，文件名为：nginx。


#!/bin/sh

   if [ -z "`grep $user /etc/passwd`" ]; then
       useradd -M -s /bin/nologin $user
   fi
   options=`$nginx -V 2>&1 | grep ‘configure arguments:‘`
   for opt in $options; do
       if [ `echo $opt | grep ‘.*-temp-path‘` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}

    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval

    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo

    return $retval

restart() {
    configtest || return $?
    stop
    sleep 1
    start
}
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}
force_reload() {
    restart
}

  $nginx -t -c $NGINX_CONF_FILE
}

    rh_status >/dev/null 2>&1

        rh_status_q && exit 0

    force-reload)
        force_reload

    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2

最后，别忘记了:chkconfig nginx on 
以后可以以下熟悉的命令管理：
service nginx status
service nginx start
service nginx stop
service nginx restart
