官網(wǎng)提供的 RHEL/CentOS 安裝方法
1：先添加nginx yum源，分為穩(wěn)定版和開(kāi)發(fā)版，復(fù)制其中一個(gè)
nginx yum源
2：新建 nginx.repo 文件，添加上面復(fù)制的源并保存
[root@localhost etc]# vim /etc/yum.repos.d/nginx.repo
3：保存后查看是否添加成功，輸入 yum list | grep nginx 命令
[root@localhost yum.repos.d]# yum list | grep nginx

4：然后直接使用 yum install nginx 安裝命令進(jìn)行安裝即可
[root@localhost yum.repos.d]# yum install nginx
5：安裝完成后使用 nginx -v 即可查看當(dāng)前安裝nginx版本
[root@localhost yum.repos.d]# nginx -v
nginx version: nginx/1.16.1
