docker-compose搭建php环境

安装docker-compose Install Docker Compose | Docker Documentation

首先创建环境目录

• data 目录用来存放redis mysql数据
• mysql nginx php redis 目录用来构建镜像，存放Dokerfile等
• www目录为项目根目录，index.php输出phpinfo()
• docker-compose.yml 为启动配置文件
• .env 存储全局变量

配置如下
nginx Dockerfile

FROM nginx
COPY default.conf  /etc/nginx/conf.d/

nginx default.conf

server {
    listen      80;
    listen  [::]:80;
    server_name  localhost;
    #access_log  /var/log/nginx/host.access.log  main;
    location / {
        root  /usr/share/nginx/html;
        index  index.html index.htm index.php;
    }
    #error_page  404              /404.html;
    # redirect server error pages to the static page /50x.html
    #
    error_page  500 502 503 504  /50x.html;
    location = /50x.html {
        root  /usr/share/nginx/html;
    }
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass  http://127.0.0.1;
    #}
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root          html;
        fastcgi_pass  php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;
        include        fastcgi_params;
    }
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

php Dockerfile

FROM php:7.4-fpm

后台构建并启动

docker-compose up -d

出现done代表安装成功
