php容器中安装源码包中的扩展

查看运行的php容器

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                    NAMES
cbf0cca7bcb5        php:7.4-fpm           "docker-php-entrypoi…"   3 days ago          Up 20 seconds       0.0.0.0:9074->9000/tcp   php7.4

进入容器

# 进入容器
[root@localhost ~]# docker exec -it php7.4 /bin/bash

查看docker提供的辅助脚本

# 按tab键可自动提示
root@cbf0cca7bcb5:/var/www/html# docker-php-
docker-php-entrypoint     docker-php-ext-configure  docker-php-ext-enable     docker-php-ext-install    docker-php-source

查询docker-php-source用法

root@cbf0cca7bcb5:/var/www/html# docker-php-source
usage: /usr/local/bin/docker-php-source COMMAND

Manage php source tarball lifecycle.

Commands:
 # 将php源tarball解压到目录中
 extract  extract php source tarball into directory /usr/src/php if not already done. # 删除已解压的php源
 delete  delete extracted php source located into /usr/src/php if not already done.```

### 将php源tarball解压到目录/usr/src/php

```bash
root@cbf0cca7bcb5:/var/www/html# docker-php-source extract
root@cbf0cca7bcb5:/var/www/html# cd /usr/src/php/ext

使用docker提供的辅助脚本安装存在于 /usr/src/php/ext 中的扩展

root@cbf0cca7bcb5:/usr/src/php/ext# docker-php-ext-install pdo

docker-php-ext-install 辅助脚本帮我执行了源码安装php扩展的一系列命令
