docker compose 一键部署LNMP环境

1. 创建docker compose目录

[root@docker ~]# mkdir -p /compose_lnmp

2. 编写nginx的dockerfile

2.1 创建目录

[root@docker ~]# cd /compose_lnmp/
[root@docker compose_lnmp]# ll
总用量 0
[root@docker compose_lnmp]# mkdir -p nginx
[root@docker compose_lnmp]# cd nginx/

2.2 编写nginx配置文件

[root@docker nginx]# vim nginx.conf 
[root@docker nginx]# cat nginx.conf 
#user nobody ;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
error_log  logs/error.log  info;

pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;

    sendfile        on;

    keepalive_timeout  65;

    gzip  on;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /var/www/html;
            index  index.php index.html index.htm;
        }
        
        location ~ .php$ {
            root           /var/www/html;
            fastcgi_pass   lnmp_php:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

    }
}

2.3 编写nginx的Dockerfile文件

[root@docker nginx]# vim Dockerfile 
[root@docker nginx]# cat Dockerfile 
#this docker file
#VERSION 1
#author:shichao@scajy.cn

FROM centos:7
MAINTAINER shichao@scajy.cn
RUN yum install -y gcc gcc-c++ make pcre pcre-devel openssl openssl-devel  pcre-davel gd-devel iproute net-tools telnet wget curl && yum clean  all && rm -rf /var/cache/yum/*
RUN useradd -M -s /sbin/nologin nginx
RUN  wget http://nginx.org/download/nginx-1.17.6.tar.gz && tar zxf  nginx-1.17.6.tar.gz && 
	cd nginx-1.17.6  && 
	./configure --prefix=/usr/local/nginx  --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module  --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module && 
	make && make install
ENV PATH /usr/local/nginx/sbin:$PATH

EXPOSE 80

ENTRYPOINT ["nginx"]

CMD ["-g","daemon off;"]

3. 编写php的dockerfile文件

3.1 创建php目录

[root@docker nginx]# cd /compose_lnmp/
[root@docker compose_lnmp]# ll
总用量 0
drwxr-xr-x. 2 root root 42 10月 19 11:32 nginx
[root@docker compose_lnmp]# mkdir -p php
[root@docker compose_lnmp]# cd php/

3.2 下载php包

• 官网下载地址: https://www.php.net/

  [root@docker php]# wget https://www.php.net/distributions/php-7.2.34.tar.gz
  [root@docker php]# ll -a
  总用量 19472
  drwxr-xr-x. 2 root root       49 10月 13 20:38 .
  drwxr-xr-x. 4 root root       30 10月 13 20:21 ..
  -rw-r--r--. 1 root root 19936114 10月 13 20:37 php-7.2.34.tar.gz
  

3.4 编写php的dockerfile文件

[root@docker php]# vim Dockerfile 
[root@docker php]# cat Dockerfile 
#this docker file
#VERSION 1
#author:shichao@scajy.cn
FROM centos:7
MAINTAINER  shichao@scajy.cn
RUN yum install -y gcc gcc-c++ make gd-devel libxml2-devel libcurl-devel libjpeg-devel libpng-devel openssl-devel &&
	yum clean all && 
	rm -rf /var/cache/yum/*
ADD php-7.2.34.tar.gz /tmp/

RUN cd /tmp/php-7.2.34 && 
    ./configure --prefix=/usr/local/php 
    --with-config-file-path=/usr/local/php/etc 
    --enable-mysqlnd --with-mysql --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd 
    --with-openssl --with-zlib --with-curl --with-gd 
    --with-jpeg-dir --with-png-dir --with-iconv 
    --enable-fpm --enable-zip --enable-mbstring && 
    make -j 4 && 
    make install && 
    cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf && 
    cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf && 
    sed -i "s/127.0.0.1/0.0.0.0/" /usr/local/php/etc/php-fpm.d/www.conf && 
    sed -i "21a daemonize = no" /usr/local/php/etc/php-fpm.conf && 
    cp  php.ini-production /usr/local/php/etc/php.ini

RUN rm -rf /tmp/php-7.2.34* 

WORKDIR /usr/local/php
EXPOSE 9000
CMD ["./sbin/php-fpm", "-c", "/usr/local/php/etc/php-fpm.conf"]

4. 使用docker compose编译lnmp环境

4.1 切换到docker compose目录下

[root@docker php]# cd /compose_lnmp/

4.2 编写docker compose配置文件

[root@docker compose_lnmp]# vim docker-compose.yml 
[root@docker compose_lnmp]# cat docker-compose.yml 
version: '3'
services:
  lnmp_nginx:
    hostname: lnmp_nginx
    build:
      context: ./nginx
      dockerfile: Dockerfile
    ports:
      - 80:80
    networks:
      - lnmp
    volumes:
      - ./nginx/nginx.conf:/usr/local/nginx/conf/nginx.conf
      - /var/www/html:/var/www/html

  lnmp_php:
    hostname: lnmp_php
    build:
      context: ./php
      dockerfile: Dockerfile
    networks:
      - lnmp
    volumes:
      - /var/www/html:/var/www/html

  mysql:
    hostname: mysql
    image: mysql:5.7
    ports:
      - 3306:3306
    networks:
      - lnmp
    volumes:
      - ./mysql/conf:/etc/mysql/conf.d
      - ./mysql/data:/var/lib/mysql
    command: --character-set-server=utf8
    environment:
      MYSQL_ROOT_PASSWORD: 123456
      MYSQL_DATABASE: lnmp
      MYSQL_USER: lnmp
      MYSQL_PASSWORD: lnmp123

networks:
  lnmp: 

5. docker compose执行构建lnmp环境

[root@docker compose_lnmp]# docker-compose -f docker-compose.yml up -d
Starting compose_lnmp_php_1   ... done
Starting compose_lnmp_nginx_1 ... done
Starting compose_lnmp_mysql_1 ... done

# 注释：
	docker-compose    			执行命令
	-f						   连接配置文件
	docker-compose.yml   		编码的配置文件
	up						   启动，只是up启动，是前台启动
	-d						   指定后台启动

6. 查看容器是否运行正常

[root@docker compose_lnmp]# docker-compose ps -a
          Name                         Command               State                 Ports              
------------------------------------------------------------------------------------------------------
compose_lnmp_lnmp_nginx_1   nginx -g daemon off;             Up      0.0.0.0:80->80/tcp               
compose_lnmp_lnmp_php_1     ./sbin/php-fpm -c /usr/loc ...   Up      9000/tcp                         
compose_lnmp_mysql_1        docker-entrypoint.sh --cha ...   Up      0.0.0.0:3306->3306/tcp, 33060/tcp

7. 浏览器访问测试
