centos7 yum 方式安装nginx

centos7系统库中默认是没有nginx的rpm包的，所以我们自己需要先更新下rpm依赖库

 

(1)使用yum安装nginx需要包括Nginx的库，安装Nginx的库

#rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

(2)使用下面命令安装nginx

#yum install nginx

(3)启动Nginx

#service nginx start

或

#systemctl start nginx.service
