composer切换源_composer全局更换镜像源的教程

composer 中如何更换全局镜像源来加快软件下载速度的方法。 composer 中的源分为局部源以及全局源，局部源一般都是项目里私有的东西这里不再介绍，主要是说一下 composer 如何更换全局镜像源的方法，composer 更换全局镜像源不会影响局部的镜像源，可以大胆的去更换。 composer 更换全局源的方法 1、查看 composer 配置的命令composer config -g -l 注意下面图示中，结果的第二行则为 composer 默认的源地址。 2、禁用默认源镜像命令composer config -g secure-http false 3、修改为阿里云镜像源composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ 注：如果想修改为腾讯云或华为云的镜像源，直接修改命令中的url地址即可！ 4、查看修改结果composer config -g -l 5、撤销修改，恢复默认配置composer config -g –unset repos.packagist 6、查看撤销是否成功。composer config -g -l composer 镜像源 下面是一些比较常用的 composer 镜像源，可根据自己服务器的运营商来选择，这样速度更快一些！ (1)、composerhttps://packagist.org (2)、phpcomposerhttps://packagist.phpcomposer.com (3)、阿里云composer镜像源https://mirrors.aliyun.com/composer (4)、腾讯云composer镜像源https://mirrors.cloud.tencent.com/composer (5)、华为云composer镜像源https://mirrors.huaweicloud.com/repository/php (6)、laravel(中国)composer镜像源https://packagist.laravel-china.org

linux 宝塔 nginx php8.0 或者 php7 安装swoole

一、安装swoole
1. 下载swoole源码，官网：http://pecl.php.net/package/swoole 挑选自己的版本下载，安装代码。PHP8以上安装swoole 5x，以下版本只能安装swoole 4x.

PHP7.4 安装代码

phpize
./configure --with-php-config=/www/server/php/74/bin/php-config
make && sudo make install

PHP8 安装代码

phpize
./configure --with-php-config=/www/server/php/80/bin/php-config
make && sudo make install
/ PHP

PHP代码http跳转到https

使用SSL(Secure Sockets Layer 安全套接层)后，发现http 与https都可以打开，但是不想让用户使用http协议。在服务器iis 或 nginx 或 apache 想尽办法，各种伪静态，各种301的跳转，最终发现还是有缺陷。

那么使用PHP来实现：

if(!((isset($_SERVER['HTTPS'])&&$_SERVER['HTTPS']=='on')||(isset($_SERVER['HTTP_X_FORWARDED_PROTO'])&&$_SERVER['HTTP_X_FORWARDED_PROTO']=='https'))){
Header("HTTP/1.1 301 Moved Permanently");
header('Location: https://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']);
}

宝塔php 7.2，php7.3，php7.4 安装 mcrypt 扩展

依次执行下面代码，我测试安装成功，可以使用

yum install libmcrypt libmcrypt-devel mcrypt mhash

wget  https://pecl.php.net/get/mcrypt-1.0.3.tgz

tar xf mcrypt-1.0.3.tgz

cd mcrypt-1.0.3

/www/server/php/73/bin/phpize

./configure --with-php-config=/www/server/php/73/bin/php-config  && make && make install

如果不成功在 php.ini 里面加上

extension=mcrypt.so
