YUM 安装
1.下载nginx包
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
2.建立nginx的yum仓库
rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm
3.下载并安装nignx
yum install nginx
4.启动nginx服务
systemctl start nginx
5.如果在浏览器中输入部署nginx环境的IP不能访问，可能是端口没有开启
firewall-cmd --zone=public --add-port=80/tcp --permanent
重启防火墙
systemctl stop firewalld.service systemctl start firewalld.service
命令含义：
--zone #作用域
--add-port=80/tcp #添加端口，格式为：端口/通讯协议
--permanent #永久生效，没有此参数重启后失效
源码编译安装
