Linux使用composer安装TP5.1

配置Linux的环境简直想吐血，我这里进行了重复更新和安装，就是因为环境问题
安装请我之前的文章:

https://blog.csdn.net/qq_42914232/article/details/103011978

一:首先确保PHP环境变量存在，才能执行PHP文件

[root@VM_0_26_centos 129]# php -v
PHP 7.2.18 (cli) (built: May  6 2019 11:33:20) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

如果执行不成功，需要将PHP位置加入到环境变量或者将PHP链接到环境变量里的目录。
怎么执行百度，我这里成功了的

二:下载composer可执行文件，并移动到环境变量的目录中。注意目录是否存在

[root@VM_0_26_centos ~]# curl -sS https://getcomposer.org/installer | php
All settings correct for using Composer
Downloading...

Composer (version 1.9.1) successfully installed to: /root/composer.phar
Use it: php composer.phar
[root@VM_0_26_centos 129.28.193.221]# mv composer.phar /usr/local/bin/composer

三:切换到国内镜像

[root@VM_0_26_centos ~]# composer config -g repo.packagist composer https://packagist.phpcomposer.com

四:更新自身

[root@VM_0_26_centos ~]# composer self-update
You are already using composer version 1.9.1 (stable channel).

五:安装TP5.1

[root@VM_0_26_centos ~]# cd /
[root@VM_0_26_centos /]# ll

好了，下载完成了
其中composer create-project topthink/think tp5这句来自于TP5.1官方文档
剩下的就是将东西移动到根目录mv tp5/ .
然后将权限-所有者，改为wwwchown www.www -R
然后删掉临时目录rm runtime -fr
这样apache指定的www会自动创建，就不会有权限问题了。
六:Apache配置
将网站的apache配置文件中的，DocumentRoot 后面的路径追加/public。
重启apache服务使配置文件生效。
