1 添加CentOS 7 Nginx yum资源库,打开终端,使用以下命令:
[root@iz2zehbmmjvren7bs4we3xz/]#rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
Retrieving http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

[root@iz2zehbmmjvren7bs4we3xz /]#
2.安装Nginx
在你的CentOS 7 服务器中使用yum命令从Nginx源服务器中获取来安装Nginx：
[root@iz2zehbmmjvren7bs4we3xz /]# yum install -y nginx
Loaded plugins: fastestmirror
base | 3.6 kB 00:00:00
epel | 4.3 kB 00:00:00
extras | 3.4 kB 00:00:00
nginx | 2.9 kB 00:00:00
updates
3 启动nginx
刚安装的Nginx不会自行启动。运行Nginx:
systemctl start nginx.service
4 CentOS 7 开机启动Nginx
[root@iz2zehbmmjvren7bs4we3xz /]# systemctl enable nginx.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
