Nginx服务测试时的一些配置:wireshark、常用搜索URL格式、关闭防火墙、siege
wrieshark
sudo yum install wireshark-gnome
sudo wireshar
（以root启动，否则看不到网卡）
网站URL格式
以查询lumia为例
google http://www.google.com/search?q=lumia
baidu http://www.baidu.com/s?wd=lumia
tb http://s.taobao.com/search?q=lumia
亚马逊 http://www.amazon.cn/s/keywords=lumia
当当 http://search.dangdang.com/?key=lumia
试了下京东，发现http://search.jd.com/Search?keyword=lumia会被跳转到http://www.jd.com/?se=deny，懒得找原因了，略过。

关闭防火墙
sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service
关闭SELinux
sudo vi /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#
enforcing - SELinux security policy is enforced.
#
permissive - SELinux prints warnings instead of enforcing.
#
disabled - SELinux is fully disabled.
SELINUX= disabled # change
# SELINUXTYPE= type of policy in use. Possible values are:
#
targeted - Only targeted network daemons are protected.
#

SELINUXTYPE=targeted
