前言

<> 很是感謝Kason老師給予的幫助！php

馬哥教到佈署LNAMP時，我遇到了一些問題：html

Nginx是代理，不須要與後端直接創建鏈接；

我開始使用跨網段沒有實現成功；

後來我使用同網段的方法，但訪問時就會跳轉到後端，查看後端日誌時，其訪問者也是客戶端IP；

總結： mysql

對windows虛擬機中的vmnet#不瞭解；

wordpress程序定其只能根據IP訪問；

windows上基於虛擬主機實現LNAMP

配置前提

關閉防火牆、SELinux，若是要啓動，則在全部配置成功之後，再行啓動；
同步時間；ntp, chrony

EPEL源和Base源；php-mbstring, php-mcrypt包依賴EPEL;

# iptables -F
# setenforce 0
//Nginx主機上配置時間服務器同步時間
# echo "allow 192.168.10/24" >> /etc/chrony.conf
# systemctl start chronyd.service
# systemctl enable chronyd.service

Nginx主機172.16.0.6上配置

安裝程序包
```
~]#  yum -y install nginx
```
啓用nginx
```
~]#  systemctl start nginx.service
```

查看端口是否監聽
