生产服务器：
OS：CentOS 6.8
1.在该目录下”/etc/init.d”新建一个nginx文件，添加下列代码。
[root@localhost init.d]# vi nginx
[root@localhost init.d]# cat nginx
#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=/application/nginx/sbin/nginx
nginx_config=/application/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
;;
stop)
stop
;;
reload)
reload

restart)

start

status)
status $prog
RETVAL=$?
;;
*)
echo $"Usage: $prog {start|stop|restart|reload|status|help}"
exit 1
esac
exit $RETVAL
2.设置开机启动服务，保存好 /etc/init.d/nginx文件后，执行以下命令:
[root@localhost init.d]# chmod 755 /etc/init.d/nginx #赋予文件执行权限
[root@localhost init.d]# chkconfig --add nginx
[root@localhost init.d]# chkconfig --level 2345 nginx on #设置开机启动
3、nginx启动、停止、无间断服务重启
[root@localhost /]# service nginx status
nginx (pid 1621 1619) 正在运行...
[root@localhost /]# service nginx stop
停止 nginx： [确定]
[root@localhost /]# service nginx start
正在启动 nginx： [确定]
[root@localhost /]# service nginx reload
重新载入 nginx： [确定]
