补充部分
一般没有进行启动设置，需要进入部署的nginx进行启动
/usr/local/nginx/sbin/nginx
下面是nginx的一个启动脚本，但是还是进行上面的配置比较好

#!/bin/bash

read -p "是否需要启动nginx（输入y/Y启动，其他不启动）：" startNginxMsg
if [ "$startNginxMsg" == 'y' ] || [ "$startNginxMsg" == 'Y' ] 
then
    /usr/local/nginx/sbin/nginx
    if [ $? -eq 0 ]
    then
        localIp=`hostname -I`
        echo "启动成功,请访问: http://$localIp"
    else
        echo "启动失败，请查看异常信息确定失败原因"
    fi
else
    echo "不启动"
fi
echo ""

nginx配置文件需要修改部分

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   /usr/local/nginx/html;
            index  index.html index.htm;
        }
---------------------------------------------------------------
location中配置的路径要对应自己部署的nginx的html路径

我的虚拟机是刚创建出来的防火墙没有关，所有访问不通，可以关闭防火墙或者开放80端口

##关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

##开放端口
[root@centos7_9-mod conf]# firewall-cmd --zone=public --add-port=80/tcp --permanent

[root@centos7_9-mod conf]# vim nginx.conf
