基于docker-compose.yml文件搭建lnmp

安装docker-compose

[root@node1 ~]# curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

[root@node1 ~]# chmod +x /usr/local/bin/docker-compose 


[root@node1 ~]# docker-compose --version
docker-compose version 1.29.2, build 5becea4c

·

创建目录和文件

[root@node1 ~]# tree compose_lnmp/
compose_lnmp/
├── docker-compose.yml
└── php
    └── Dockerfile

1 directory, 2 files

编写php/Dockerfile

• 由于官方的php-fpm镜像缺少一些扩展功能，所以要使用dockerfile构建新的镜像
• 注意配置时区和mysql扩展

[root@node1 ~]# vim compose_lnmp/php/Dockerfile 
FROM php:7.0-fpm
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
    && echo "Asia/Shanghai" > /etc/timezone
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libmcrypt-dev \
        libpng-dev \
        libmemcached-dev \
        zlib1g-dev \
        libcurl4-openssl-dev \
        libxml2-dev \
        --no-install-recommends && rm -rf /var/lib/apt/lists/* \
    && docker-php-ext-install -j$(nproc) \
        iconv mcrypt gettext curl mysqli pdo pdo_mysql zip \
        mbstring bcmath opcache xml simplexml sockets hash soap \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd

CMD ["php-fpm", "-F"]

编写docker-compose.yml

• 官方推荐使用volume优于bind mount
• volume默认存放在/var/lib/docker/volumes下

[root@node1 ~]# vim compose_lnmp/docker-compose.yml
version: "3"

services:
  mysql:
    hostname: mysql
    restart: always
    image: mysql:5.6
    container_name: mysql
    ports:

    volumes:
      - mysql-config:/etc/mysql
      - mysql-log:/var/log/mysql
      - mysql-data:/var/lib/mysql
    environment:

      MYSQL_PASSWORD: user123
  php:
    hostname: php

    container_name: php
    build:
      context: ./php
      dockerfile: Dockerfile

      - php-config:/usr/local/etc
  nginx:
    hostname: nginx
    restart: always
    container_name: nginx
    image: nginx:1.17.0
    ports:
      - "80:80"
      - "443:443"
    links:
      - "php:php"
    volumes:
      - nginx-config:/etc/nginx
      - nginx-log:/var/log/nginx
      - nginx-html:/usr/share/nginx/html

volumes:
  mysql-config:
  mysql-log:
  mysql-data:
  nginx-html:
  php-config:
  nginx-config:
  nginx-log:

启动服务

[root@node1 ~]# cd compose_lnmp/
[root@node1 compose_lnmp]# docker-compose up -d //启动
Creating network "compose_lnmp_default" with the default driver
Creating volume "compose_lnmp_mysql-config" with default driver
Creating volume "compose_lnmp_mysql-log" with default driver
Creating volume "compose_lnmp_mysql-data" with default driver

[root@node1 compose_lnmp]# docker-compose restart  //重启

查看容器是否启动

[root@localhost compose_lnmp]# docker ps

数据化持久目录

[root@localhost compose_lnmp]# docker volume ls

配置php

//默认的php.ini的文件是没有的，需要手动把模板配置文件复制为php.ini
[root@localhost compose_lnmp]# cd /var/lib/docker/volumes/compose_lnmp_php-config/_data/php
[root@localhost php]# ls
conf.d  php.ini-development  php.ini-production
[root@localhost php]# cp php.ini-production php.ini


[root@localhost php]# vim php.ini
date.timezone = Asia/shanghai
//取消注释，修改时区

配置nginx

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm index.php;  //此处添加index.php
    }




    location ~ \.php$ {
        root           html;
        fastcgi_pass   php:9000;  //php为容器的名称
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME   /var/www/html$fastcgi_script_name; //此处更改为存放网页的地方
        include        fastcgi_params;
    }

测试mysql

[root@localhost ~]# docker container exec -it mysql bash

root@mysql:/# mysql -uroot -p123456

验证php

编写php页面

[root@localhost ~]# vim /var/lib/docker/volumes/compose_lnmp_nginx-html/_data/index.php
<?php
    phpinfo();
?>

重启所有容器

[root@localhost ~]# cd compose_lnmp/
[root@localhost compose_lnmp]# docker-compose restart
