php安装扩展

Qter

composer global require laravel/installer
[Changed current directory to /root/.config/composer]

Problem 1
    - laravel/installer v3.0.1 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - laravel/installer v3.0.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - Installation request for laravel/installer ^3.0 -> satisfiable by laravel/installer[v3.0.0, v3.0.1].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/opt/remi/php72/php.ini
    - /etc/opt/remi/php72/php.d/10-opcache.ini
    - /etc/opt/remi/php72/php.d/20-bcmath.ini

  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

yum search zip php
yum install -y php72-php-pecl-zip.x86_64
yum install -y unzip



安装扩展注意

与Apache+PHP或者Nginx+PHP的运行模式不同，WorkerMan是基于PHP命令行 PHP CLI 运行的，使用的是不同的PHP可执行程序，使用的php.ini文件也可能不同。所以在网页中打印phpinfo()看到安装了某个扩展，不代表命令行的PHP CLI也安装了对应的扩展。

如何确定PHP CLI安装了哪些扩展

运行 php -m 会列出命令行 PHP CLI 已经安装的扩展，结果类似如下：

1. ~# php -m
   
2. [PHP Modules]
   
3. libevent
   
4. posix
   
5. pcntl

如何确定PHP CLI 的php.ini文件的位置

当我们安装扩展时，可能需要手动配置php.ini文件，把扩展加进去，所以要确认PHP CLI的php.ini文件的位置。可以运行php --ini查找PHP CLI的ini文件位置，结果类似如下(各个系统显示结果会有差异)：

1. 
   
2. ~# php --ini
   
3. Configuration File (php.ini) Path: /etc/php5/cli
   
4. Loaded Configuration File:         /etc/php5/cli/php.ini
   
5. Scan for additional .ini files in: /etc/php5/cli/conf.d
   
6. Additional .ini files parsed:      /etc/php5/cli/conf.d/apc.ini,
   
7. /etc/php5/cli/conf.d/libevent.ini,
   
8. /etc/php5/cli/conf.d/memcached.ini,
   
9. /etc/php5/cli/conf.d/mysql.ini,
   
10. /etc/php5/cli/conf.d/pdo.ini,
    
11. /etc/php5/cli/conf.d/pdo_mysql.ini

给PHP CLI安装扩展（安装memcached扩展为例）

方法一、使用apt或者yum命令安装

如果PHP是通过 apt 或者 yum 命令安装的，则扩展也可以通过 apt 或者 yum 安装

centos等系统yum安装PHP扩展方法

1、利用yum search查找扩展包

~# yum search memcached php

php-pecl-memcached - memcached module for php5

2、使用yum install安装扩展包

~# yum install -y php-pecl-memcached

说明：

使用apt或者yum安装PHP扩展会自动配置php.ini文件，安装完直接可用，十分方便。缺点是有些扩展在apt或者yum中没有对应的扩展安装包。
