docker安装php镜像和扩展

先安装好docker，这里不做记录
1.去https://hub.docker.com/_/php/tags查询自己需要的版本，复制命令
docker pull php:8.2-rc-cli-buster
ps: 下载慢可以配置docker镜像，如阿里云和163等

2.docker run -t -i php:8.2 /bin/bash
这里最好配置好端口映射-p: 指定端口映射，格式为：主机(宿主)端口:容器端口
目录映射-v /data:/data
也可以后期修改docker配置文件，不过有点麻烦。。。

3.docker exec -it php:8.2 /bin/bash
进入运行的容器中，可以执行命令

到这里就可以使用了
如果需要连接宿主机的软件如mysql redis等，一般宿主机默认ip 172.17.0.1
记录下一些常用命令

docker start *  // 启动一个容器
docker images   // 查看镜像列表
docker ps -a    // 查看所有容器

vscode可以搜索安装docker插件，可以图形化启动容器，也可以编辑器终端打开容器shell

docker容器添加新的端口映射方法
/var/lib/docker/containers/<容器Id>/hostconfig.json

{
    "PortBindings":{
			"22/tcp":[{"HostIp":"","HostPort":"10112"}],
			"5901/tcp":[{"HostIp":"","HostPort":"10113"}],
	},
}

/var/lib/docker/containers/<容器Id>/config.v2.json

{
“ExposedPorts”:{
“22/tcp”:{},
“5901/tcp”:{}
}
}

```

docker安装php扩展

在php容器中创建/usr/src/php目录
docker-php-source extract

docker-php-ext-configure
docker-php-ext-enable 启用扩展
docker-php-ext-install 安装扩展

pecl install redis
docker-php-ext-enable redis

checking for libpng… no
configure: error: Package requirements (libpng) were not met:

No package ‘libpng’ found

apt-get install libpng-dev

configure: error: Package requirements (zlib >= 1.2.0.4) were not met:

No package ‘zlib’ found

apt-get install zlib1g-dev

kill -USR2 1 容器内重启php-fpm

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name; // nginx修改配置

// 安装composer
curl -sS https://getcomposer.org/installer | php
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
