LNMP填坑笔记: docker-compose.yml 部署 Mysql 5.7 和 php:5.5.38-fpm 和最新 Nginx

部署需要的文件打包 lnmp.tar

昨天有朋友要使用php5.3才能运行一个框架程序，DockerHub找到只有 php:5.5.38-fpm 镜像，然后就是使用 docker-compose.yml 部署 LNMP，因为Nginx和Php-Fpm不是同一个容器，搞了个把小时 phpinfo 才跑起来，但是自己也没有摸透。
我是使用 php-fpm 容器中 apt安装一个 低版本Nginx，自动配置起来，但是其实有很多坑，后来在另一个虚拟机环境搞到晚上11点才算正式摸透了。

docker-compose.yml

version: '3.1'
services:
    db:
        image: mysql:5.7
        container_name: mysql
        command: --default-authentication-plugin=mysql_native_password
        restart: always
        volumes:
            - /data/mysql:/var/lib/mysql
        environment:
            MYSQL_DATABASE: test
            MYSQL_ROOT_PASSWORD: Mysql@2021

    adminer:
        image: adminer
        container_name: adminer
        restart: always
        ports:
            - 10086:8080

    nginx:
        image: nginx
        container_name: nginx
        restart: always
        volumes:
            - /data/www/:/var/www/html
        ports:
            - 80:80
            - 443:443

    php:
        image: php:5.5.38-fpm
        container_name: php
        restart: always
        volumes:
            - /data/www/:/var/www/html
        ports:
            - 9000:9000

重点来说 docker-compose.yml,使用这个方式部署的容器都可以使用容器名和组件名来代替IP互相访问。

比如使用访问数据库使用 db或者mysql连接， php:9000 用来连接php-fpm , 测试http使用 curl nginx:80

php-fpm容器的目录挂载是重点，昨天一直被坑在这里，显示错误 File not found. 而网上的文章都没有提这个重点。

部署和修改配置命令

# 安装 docker-compose 部署工具
wget https://lyvba.com/docker-compose  -O /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
# 先建立 docker-compose.yml ，然后使用命令部署
docker-compose up -d
docker ps -a
docker cp /usr/bin/nano nginx:/usr/bin
docker exec -it nginx bash
mkdir -p /var/www/html/   # 官方nginx默认没这个目录，所以要建立一个
nano /etc/nginx/conf.d/default.conf
nginx -t
nginx -s reload
docker restart nginx

在宿主机 /data/www/ 目录中创建 index.php 文件，用以 Nginx Web 服务器测试 PHP-FPM

<?php phpinfo(); ?>

Nginx 配置，参考apt安装的nginx配置，而不是官方镜像的配置

• Nginx 反向代理 Php-fpm 解释 php脚本，配置两行命令

  include snippets/fastcgi-php.conf;  # fastcgi配置，fastcgi-php.conf 文件又包含 fastcgi.conf
  fastcgi_pass php:9000;  # php:9000 是 Php-fpm容器开放的端口

• 所以实际部署的时候 完全可以把三个文件写到一个支持ssl证书的 https.conf 配置文件中

default.conf

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;
    #
    # Self signed certs generated by the ssl-cert package
    # Don't use them in a production server!
    #
    # include snippets/snakeoil.conf;

    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.php index.htm index.nginx-debian.html;

    server_name _;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ .php$ {
        include snippets/fastcgi-php.conf;
    #
    #    # With php5-cgi alone:
        fastcgi_pass php:9000;
    #    # With php5-fpm:
    #    fastcgi_pass unix:/var/run/php5-fpm.sock;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /.ht {
    #    deny all;
    #}
