docker-compose编排启动LNMP

2-1、docker-compose启动php

#生成php镜像
[root@rocky8 data]#vim /data/dockerfile/ubuntu_php/Dockerfile
FROM ubuntu_base:v1.0
LABEL maintainer="www.wang.org" version="ubuntu_php:v1.0"

ADD php-7.4.30.tar.gz /usr/local/src/

RUN sed -i s/archive.ubuntu.com/mirrors.ustc.edu.cn/g /etc/apt/sources.list
RUN apt update && \\
    apt -y install gcc make libssl-dev libxml2-dev libsqlite3-dev libcurl3-dev libxml2 sqlite3 pkg-config zlib1g-dev libonig-dev libkrb5-dev libssl-dev libbz2-dev libcurl4-openssl-dev libpng-dev libjpeg-dev libfreetype-dev g++ libonig-dev libxslt-dev libzip-dev && \\
    cd /usr/local/src/php-7.4.30 && \\
    ./configure --prefix=/apps/php74 --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-openssl --with-zlib --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --enable-mbstring --enable-xml --enable-sockets --enable-fpm --enable-maintainer-zts --disable-fileinfo && \\
    make && make install && \\
    useradd -r -u 888 nginx

COPY php.ini /usr/local/src/php-7.4.30/
COPY www.conf /apps/php74/etc/php-fpm.d/
COPY php-fpm.conf /apps/php74/etc/
COPY run_php.sh /

CMD ["/run_php.sh"]

[root@rocky8 data]#vim /data/dockerfile/ubuntu_php/run_php.sh
/apps/php74/sbin/php-fpm
tail -f /etc/hosts

#编写docker-compose.yml
[root@rocky8 php]#vim docker-compose.yml
version: 3.3
services:
  ubuntu_php:
    container_name: php
    image: "ubuntu_php:v1.1"

2-2、docker-compose启动nginx

#生成nginx镜像
[root@rocky8 ubuntu_nginx_base]#vim Dockerfile
FROM ubuntu_base:v1.0
LABEL maintainer="www.wang.org" version="ubuntu_nginx_base:v1.0"

ADD nginx-1.22.0.tar.gz /usr/local/src/

RUN apt update && \\
    apt install -y nfs-kernel-server nfs-common gcc openssh-server lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev unzip zip make

RUN cd /usr/local/src/nginx-1.22.0 && \\
    ./configure --prefix=/apps/nginx && \\
    make && make install && \\
    ln -s /apps/nginx/sbin/nginx /usr/bin && \\
    mkdir /apps/nginx/conf/conf.d && \\
    rm -rf /usr/local/src/nginx-1.22.0/*

ADD nginx.conf /apps/nginx/conf/nginx.conf

RUN groupadd -g 888 -r nginx && \\
    useradd -u 888 -g nginx -r -s /sbin/nologin nginx && \\
    chown -R nginx.nginx /apps/nginx/

EXPOSE 80 443

CMD ["/apps/nginx/sbin/nginx","-g","daemon off;"]

[root@rocky8 ubuntu_nginx_base]#docker build -t ubuntu_nginx_base:v1.0 .

[root@rocky8 nginx]#vim docker-compose.yml
version: 4.4
services:
  ubuntu_nginx_base:
    container_name: ubuntu_nginx
    image: "ubuntu_nginx_base:v1.0"
    volumes:
      - /data/conf.d:/apps/nginx/conf/conf.d
      - /data/wordpress:/data/wordpress
    ports:
      - "80:80"
    restart: always

2-3、docker-compose启动mysql

#编写docker-compose.yml
[root@rocky8 mysql]#vim docker-compose.yml 

version: 5.5
services:
  mysql:
    container_name: mysql
    image: mysql:8.0.30-oracle
    environment:
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_DATABASE=wordpress
      - MYSQL_USER=wordpress
      - MYSQL_PASSWORD=123456
    ports:
      - "3306:3306"
    volumes:
      - /data/mysql:/var/lib/mysql

2-4、docker-compose启动多个容器

#编写docker-compose.yml启动php+nginx+mysql:
[root@rocky8 docker-compose]#vim docker-compose.yml 
version: 1.0
services:
  nginx:
    image: ubuntu_nginx_base:v1.0
    container_name: nginx
    volumes:
      - /data/conf.d:/apps/nginx/conf/conf.d
      - /data/wordpress:/data/wordpress
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
  db:
    image: mysql:8.0.30-oracle
    container_name: mysql
    restart: unless-stopped
    environment:
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_DATABASE=wordpress
      - MYSQL_USER=wordpress
      - MYSQL_PASSWORD=123456
    volumes:
      - /data/mysql:/var/lib/mysql
    network_mode: container:nginx
    depends_on:
      - nginx

  php:
    image: ubuntu_php:v1.1
    container_name: php
    restart: unless-stopped
    network_mode: container:nginx
    volumes:
      - /data/wordpress:/data/wordpress
    depends_on:
      - nginx

[root@rocky8 docker-compose]#docker ps -a

# 注意：端口映射和自定义网络模式冲突
       先启动nginx容器，端口映射80和443，别的容器共享nginx容器网络，所以需要加上depends_on（意思依赖nginx容器）。
# php也需要挂载/data/wordpress卷，因为nginx代理动态页面都需要php处理。
