3. 制作镜像

　 * 构建php dockerfile

#Php-fpm
#Version 1.0.1
#Author lisea

#Base Image
FROM centos:7

#Maintainer
MAINTAINER lisea [email protected]

#Commands
RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
RUN yum install php-fpm -y
RUN sed -i -e ‘s\listen = 127.0.0.1:9000\listen = 0.0.0.0:9000\g‘ -e ‘s\listen.allo
wed_clients = 127.0.0.1\;listen.allowed_clients = 127.0.0.1\g‘ /etc/php-fpm.d/www.c
onf
RUN sed -i ‘s\;daemonize = yes\daemonize = no\g‘ /etc/php-fpm.conf

EXPOSE 9000
CMD ["php-fpm"]

　 * 构建 php 镜像

[[email protected] php-fpm]# docker build -t lisea/php-fpm:v1.0.1 .

   * 准备nginx配置nginx.conf文件

user nginx nginx;
worker_processes auto;
daemon off;

error_log /var/log/error_nginx.log crit;
pid /var/run/nginx.pid;
worker_rlimit_nofile 102400;

events {
  use epoll;
  worker_connections 102400;
  multi_accept on;
}

http {
  include mime.types;
  default_type application/octet-stream;
  server_names_hash_bucket_size 128;
  client_header_buffer_size 4k;
  large_client_header_buffers 4 32k;
  client_max_body_size 1024m;
  client_body_buffer_size 10m;
  sendfile on;
  tcp_nopush on;
  keepalive_timeout 60;
  server_tokens off;
  tcp_nodelay on;

  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;
  fastcgi_read_timeout 300;
  fastcgi_buffer_size 64k;
  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;
  fastcgi_intercept_errors on;

  #Gzip Compression
  gzip on;
  gzip_buffers 16 8k;
  gzip_comp_level 6;
  gzip_http_version 1.1;
  gzip_min_length 256;
  gzip_proxied any;
  gzip_vary on;
  gzip_types
    text/xml application/xml application/atom+xml application/rss+xml application/xhtml+xml image/svg+xml
    text/javascript application/javascript application/x-javascript
    text/x-json application/json application/x-web-app-manifest+json
    text/css text/plain text/x-component
    font/opentype application/x-font-ttf application/vnd.ms-fontobject
    image/x-icon;
  gzip_disable "MSIE [1-6]\.(?!.*SV1)";

  #If you have a lot of static files to serve through Nginx then caching of the files‘ metadata (not the actual files‘ contents) can save some latency.
  open_file_cache max=102400 inactive=20s;
  open_file_cache_valid 30s;
  open_file_cache_min_uses 1;
  open_file_cache_errors on;

########################## vhost #############################
  include conf.d/*.conf;
}

   * 准备nginx配置php服务相关 nginx_localhost_80.conf 文件

     php:9000是通过后面的--link 容器之间互联指定

server {
  listen 80;
  server_name localhost;
  root /data/www;
  index index.html index.htm index.php;

  location ~ [^/]\.php(/|$) {
    fastcgi_pass php:9000;
    #fastcgi_pass unix:/usr/local/php-fastcgi/php-fpm.sock;
    fastcgi_index index.php;
    include fastcgi.conf;
  }
  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|mp4|ico)$ {
    expires 30d;
    access_log off;
  }
  location ~ .*\.(js|css)?$ {
    expires 7d;
    access_log off;
  }
  location ~ /\.ht {
    deny all;
  }
}

   * 构建 nginx dockerfile 文件

#Nginx
#Version 1.0.1
#Author lisea

#Base Image
FROM centos:7

#Maintainer
MAINTAINER lisea [email protected]

#Commands
RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
RUN yum install nginx -y
ADD nginx.conf /etc/nginx/nginx.conf
ADD nginx_localhost_80.conf /etc/nginx/conf.d/localhost_80.conf

EXPOSE 80
CMD ["nginx"]

　 * 构建 nginx 镜像

[[email protected] nginx]# docker build -t lisea/nginx:v1.0.1 .

   * 准备mariadb 启动脚本 startup.sh

#!/bin/bash
if [ ! -f /var/lib/mysql/ibdata1 ]; then
        mysql_install_db
        chown mysql.mysql -R /var/lib/mysql
        /usr/bin/mysqld_safe &
        sleep 10s
        mysql -e "grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘; FLUSH PRIVILEGES;"
        kill -s TERM `ps aux | grep mysqld | grep -v ‘grep‘ | awk ‘{print $2}‘`
        sleep 10s
fi
/usr/bin/mysqld_safe

 

  * 构建mariadb(mysql) dockerfile

#Mariadb
#Version 1.0.1
#Author lisea

#Base Image
FROM centos:7

#Maintainer
MAINTAINER lisea [email protected]

#Commands
RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
RUN yum install mariadb-server mariadb -y
ADD startup.sh /opt/startup.sh
RUN chmod +x /opt/startup.sh

EXPOSE 3306
CMD ["/bin/bash","/opt/startup.sh"]

   * 构建 mysql 镜像

[[email protected] mysql]# docker build -t lisea/mariadb:v1.0.1 .

   * 查看所有镜像

[[email protected] lnmp]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
lisea/mariadb       v1.0.1              5925448a6fb6        3 minutes ago       493.6 MB
lisea/nginx         v1.0.1              f1aba93ce33d        52 minutes ago      391.4 MB
lisea/php-fpm       v1.0.1              d205ea9fcdba        About an hour ago   350.1 MB
docker.io/centos    7                   3bee3060bfc8        2 weeks ago         192.5 MB

4. 编写docker-compose

   * docker-compose.yml

version: "2"
services:
  lnmp_nginx:
    image: lisea/nginx:v1.0.1
    ports:
      - "8080:80"
    links:
      - "lnmp_php:php"
    volumes:
      - /data/www:/data/www
  lnmp_php:
    image: lisea/php-fpm:v1.0.1
    volumes:
      - /data/www:/data/www
  lnmp_mariadb:
    image: lisea/mariadb:v1.0.1
    ports:
      - "3306:3306"
    volumes:
      - /data/mariadb:/var/lib/mysql

   * 开始构建并运行 -d 指定后台运行

[[email protected] lnmp]# docker-compose up -d
Creating network "lnmp_default" with the default driver
Creating lnmp_lnmp_php_1 ... 
Creating lnmp_lnmp_mysql_1 ... 
Creating lnmp_lnmp_php_1
Creating lnmp_lnmp_php_1 ... done
Creating lnmp_lnmp_mariadb_1 ... done
Creating lnmp_lnmp_nginx_1 ... done

   * 查看端口监听状态

[[email protected] lnmp]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      975/sshd               
tcp6       0      0 :::3306                 :::*                    LISTEN      15138/docker-proxy- 
tcp6       0      0 :::8080                 :::*                    LISTEN      15320/docker-proxy- 
tcp6       0      0 :::22                   :::*                    LISTEN      975/sshd

5. 测试lnmp环境

　 * 路径切换到nginx web目录　[/data/www]

[[email protected] lnmp]# cd /data/www/

   * index.php

<?php
  phpinfo();
?>

   * 浏览器访问　ip:8080/index.php

6. 总结

以需求驱动技术，技术本身没有优略之分，只有业务之分。
