不明白为何挂载mysql下的data的时候多出那么多文件server { listen 80; server_name localhost; #charset koi8-r; #access_log /var/log/nginx/host.access.log main; location / { root /usr/nginx-2/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 /usr/nginx-2/php; #php容器下的工作路径 fastcgi_pass lnmp_php-container:9000; #container name fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$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; #} }
其中重点在于加入location ~ \.php${}的匹配信息(大致了解就是nginx在匹配路径文件时，如果后缀是php文件，即向容器端口去发送请求，从而得到运行php容器中相应路径下的index.php文件)
同时了解PHP的也应该知道，该脚本语言与HTML是兼容的。
前面3个root、fastcgi_pass、fastcgi_index容易理解，后面两个就不明白为啥了(直接写上就完事)
version: "3" services: nginx: image: lnmp_nginx container_name: lnmp_nginx-container build: ./nginx ports: - "80:80" links: - "php" volumes: - ./nginx/html/:/usr/nginx-2/html/ - ./nginx/default.conf:/etc/nginx/conf.d/default.conf php: image: lnmp_php container_name: lnmp_php-container build: ./php ports: - "9000:9000" volumes: - ./php/phpfile/:/usr/nginx-2/php/ links: - "mysql" stdin_open: true tty: true mysql: image: lnmp_mysql container_name: lnmp_mysql-container build: ./mysql ports: - "3306:3306" volumes: - ./mysql/data/:/var/lib/mysql/ environment: MYSQL_ROOT_PASSWORD : 123
这里用到的几个基本的就是，image和container_name定义镜像名与容器名，build相对路径下寻找Dockerfile定制镜像，ports端口映射。
volumes挂载数据卷或环境(稍微了解一下就是将主机的某个文件或路径补充到容器下的文件路径之后，所体现就是形成同一文件环境，主机内修改文件信息可永久性反馈到容器内)
...
构建成功
<?php phpinfo();?>
说明端口访问PHP环境成功
搭建完之后PHP没有mysqli，有pdo但不支持mysql，于是就去安装一下呗
写index.php执行php文件
<?php $servername = "lnmp_mysql-container"; $username = "root"; $password = "123"; // 创建连接 $conn = new mysqli($servername, $username, $password); // 检测连接 if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } echo "连接成功"; ?>
结果：
