首先，请确保本机已安装Docker并可正常运行； 本地准备centos7.2镜像 （如本地没有，请执行 docker pull centos:7.2.1511 自行下载）

构建容器（基于Centos7.2镜像）

docker run -it --privileged=true -v /sys/fs/cgroup:/sys/fs/cgroup --name linux-dev centos:7.2.1511 /usr/sbin/init

进入容器

docker exec -it linux-dev /bin/bash

更新源

yum install -y wget
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum update
yum makecache

安装基础工具

yum -y install make sudo passwd wget autoconf automake cmake perl-CPAN libcurl-devel libcurl libtool gcc gcc-c++ glibc-headers zlib-devel git git-lfs telnet ctags lrzsz jq expat-devel openssl-devel lsof libjpeg libjpeg-devel net-tools

安装Nginx

1. 将nginx的软件源添加到centos 7 系统中：

   yum localinstall -y http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
   

2. 安装nginx软件：

   yum install nginx -y
   

3. 启动nginx服务并加入开机启动项：

   systemctl start nginx && systemctl enable nginx
   

安装PHP

1. 添加php的软件源到系统中，此处安装php7.2

   yum localinstall -y https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
   

2. 安装php软件以及扩展：

   yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml
   

3. 启动php-fpm服务：

   systemctl start php-fpm && systemctl enable php-fpm
   

4. 查看php扩展： ```

   php -m

[PHP Modules] bz2 calendar … zlib

[Zend Modules] Zend OPcache

#### 安装composer
1. 执行以下命令，会在当前目录新建composer-setup.php文件

php -r “copy(‘https://getcomposer.org/installer’, ‘composer-setup.php’);”

2. 执行以下命令将 composer 安装到 /usr/local/bin 目录下，并且重命名 composer.phar 文件 (有可能因网络问题报错，重试即可)

php composer-setup.php –install-dir=/usr/local/bin –filename=composer

3. 删除当前目录下的 composer-setup.php 安装文件

php -r “unlink(‘composer-setup.php’);” ```

1. 检查安装是否成功 ```

   composer __ / __/_ __ ___ __ __ ____ ___ / / / __ \/ __ `__ \/ __ \/ __ \/ / _ \/ __/ / // // / / / / / / // / // (__ ) / / _/_// // // ./_//___// /_/ Composer version 2.3.5 2022-04-13 16:43:00

Usage: command [options] [arguments] …

#### 创建工作目录（后续代码存放目录）

mkdir /opt/www/

#### NG配置

新建nginx配置文件：

vi /etc/nginx/conf.d/www.conf

server { listen 80; #监听端口号 server_name localhost; #主机名或域名或ip root /opt/www; #网站根目录 index index.php index.html; #支持解析的文件类型 location ~ .php$ { fastcgi_pass 127.0.0.1:9000; #代理到本机的9000端口，解析php程序 fastcgi_index index.php; fastcgi_param DOCUMENT_ROOT /opt/www; fastcgi_param SCRIPT_FILENAME /opt/www$fastcgi_script_name; include fastcgi_params; client_max_body_size 20m; fastcgi_read_timeout 7200;

}  }

编辑后重启NG

/usr/sbin/nginx -s reload

#### 检验环境安装是否成功

1. 创建测试文件 /opt/www/index.php

</?php echo “Hello World”;

2. 执行命令 curl -i localhost/index.php

HTTP/1.1 200 OK Server: nginx/1.20.2 Date: Wed, 20 Apr 2022 09:53:50 GMT Content-Type: text/html; charset=UTF-8 Transfer-Encoding: chunked Connection: keep-alive X-Powered-By: PHP/7.2.34 Hello World ```
