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：~# php -m
libevent
posix
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)：
~# php --ini
Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File: /etc/php5/cli/php.ini
Scan for additional .ini files in: /etc/php5/cli/conf.d
Additional .ini files parsed: /etc/php5/cli/conf.d/apc.ini,
/etc/php5/cli/conf.d/libevent.ini,
/etc/php5/cli/conf.d/memcached.ini,
/etc/php5/cli/conf.d/mysql.ini,
/etc/php5/cli/conf.d/pdo.ini,
/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 phpphp-pecl-memcached - memcached module for php52、使用yum install安装扩展包~# yum install -y php-pecl-memcachedReading package lists... DoneReading state information... Done...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。https://blog.csdn.net/abel004/article/details/53957431
