首先，在linux系统的/etc/init.d/目录下创建nginx文件，使用如下命令： vi /etc/init.d/nginx 在脚本中添加如下内容：
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
# It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
echo "nginx already running...."
exit 1
fi
echo -n $"Starting $prog: "
daemon $nginxd -c ${nginx_config}
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
echo -n $"Stopping $prog: "
killproc $nginxd
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
}
# reload nginx service functions.
reload() {
echo -n $"Reloading $prog: "
#kill -HUP `cat ${nginx_pid}`
killproc $nginxd -HUP
RETVAL=$?
echo
}
# See how we were called.
case "$1" in
start)
start

status)
status $prog
RETVAL=$?

*)
echo $"Usage: $prog {start|stop|restart|reload|status|help}"
exit 1
esac
exit $RETVAL
注意红色加粗部分，需要将路径改为自己机器的相应路径。
保存脚本文件后设置文件的执行权限：
chmod a+x /etc/init.d/nginx
然后，就可以通过该脚本对nginx服务进行管理了：
/etc/init.d/nginx start /etc/init.d/nginx stop使用chkconfig进行管理
上面的方法完成了用脚本管理nginx服务的功能，但是还是不太方便，比如要设置nginx开机启动等。这时可以使用chkconfig来设置。
先将nginx服务加入chkconfig管理列表：
chkconfig --add /etc/init.d/nginx加完这个之后，就可以使用service对nginx进行启动，重启等操作了：
service nginx start #开启 service nginx stop #停止 service nginx restart #重启 service nginx reload #重新加载
设置开机默认启动
chkconfig --add nginx //添加系统服务 chkconfig --level 345 nginx on //设置开机启动,启动级别 chkconfig --list nginx //查看开机启动配置信息
