Nginx

四项确认
1. 确认系统网络
ping www.baidu.com  
2. 确认yum可用
yum list|grep gcc
3. 确认关闭iptables规则
iptables -F
4. 确认关闭selinux
setenforce 0
5. 安装依赖
yum -y install gcc gcc-c++ autoconf pcre pcre-devel make automake 
yum -y install wget httpd-tools vim

1. IO多路复用epoll
2. 轻量级
3. CPU亲和(affinity)
4. sendfile

指定nginx官方提供的yum源
sudo vim /etc/yum.repos.d/nginx.repo
