Dockerfile 搭建 PHP+Nginx+Wordpress

  • 安装流程规划

    • wordpress装在宿主机,相当于一台NFS
    • php装在一台容器内
    • nginx装在一个容器内
    • 将容器挂载到wordpress站点目录以实现访问
  • 目录最终结构,对应放置

[root@docker1 ~] mkdir /code
[root@docker1 ~] cd /code
[root@docker1 code] ll /code/
total 4
drwxr-xr-x 5 www  www  4096 Mar 27 18:03 wordpress
drwxr-xr-x 2 root root   75 Mar 27 18:32 php
drwxr-xr-x 2 root root   67 Mar 27 18:16 nginx
drwxr-xr-x 2 root root   80 Mar 26 22:14 mysql
  • 下载、解压wordpress
[root@docker1 code] wget https://cn.wordpress.org/latest-zh_CN.tar.gz
[root@docker1 code] tar xf *gz

一、准备php文件+构建为镜像

  • Dockerfile
  • php-fpm.conf
  • php.ini
  • www.conf

5.构建为镜像

[root@docker1 php] docker build -t lnmp-php:v1 .

二、准备Nginx文件+构建为镜像

  • Dockerfile
  • nginx.conf
  • linux.wp.com.conf

1.Dockerfile

FROM nginx
RUN groupadd www -g 666 && \
    useradd www -u 666 -g 666 -s /sbin/nologin -M
ADD linux.wp.com.conf /etc/nginx/conf.d/
ADD nginx.conf /etc/nginx/
RUN mkdir /code/wordpress/ -p
RUN rm -rf /etc/nginx/conf.d/default.conf
EXPOSE 80
WORKDIR /root
CMD ["nginx","-g","daemon off;"]

2.nginx.conf

user  www;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       /etc/nginx/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  /var/log/nginx/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    keepalive_timeout  65;
    #gzip  on;
    include /etc/nginx/conf.d/*.conf;
}

3.linux.wp.com.conf

server {
    listen 80;
    server_name linux.wp.com;
    
    location / {
        root /code/wordpress;
        index index.php;
    }
    
    location ~* \.php$ {
        fastcgi_pass php:9000;
        fastcgi_param SCRIPT_FILENAME /code/wordpress/$fastcgi_script_name;
        include fastcgi_params;
    }
}

4.构建为镜像

[root@docker1 nginx] docker build -t lnmp-nginx:v1 .

三、准备mysql文件+构建为镜像

  • Dockerfile
  • privileges.sql
  • schema.sql
  • setup.sh

1.Dockerfile

FROM mysql:5.7

#设置免密登录
ENV MYSQL_ALLOW_EMPTY_PASSWORD yes

#添加所需文件
ADD setup.sh /mysql/setup.sh
ADD schema.sql /mysql/schema.sql
ADD privileges.sql /mysql/privileges.sql

#设置容器启动时执行的命令
CMD ["sh", "/mysql/setup.sh"]

2.privileges.sql

use mysql;
grant all on wordpress.* to wp@'172.18.0.%' identified by '123';
SET PASSWORD=PASSWORD('123456');
flush privileges;

3.schema.sql

create database wordpress;

4.setup.sh

#!/bin/bash
set -e

#查看mysql服务的状态,方便调试,这条语句可以删除
echo `service mysql status`
 
echo '1.启动mysql....'
#启动mysql
service mysql start
sleep 3
echo `service mysql status`
 
echo '2.开始导入数据....'
#导入数据
mysql < /mysql/schema.sql
echo '3.导入数据完毕....'
 
sleep 3
echo `service mysql status`
 
#重新设置mysql密码
echo '4.开始修改密码....'
mysql < /mysql/privileges.sql
echo '5.修改密码完毕....'
 
#sleep 3
echo `service mysql status`
echo `mysql容器启动完毕,且数据导入成功`
 
tail -f /dev/null

5.构建为镜像

[root@docker1 mysql] docker build -t lnmp-mysql:v1 .

6.查看构建镜像

[root@docker1 ~] docker images
REPOSITORY   TAG       IMAGE ID       CREATED        SIZE
lnmp-php     v1        0f5aa301288b   21 hours ago   1.23GB
lnmp-nginx   v1        de9f843b40ab   22 hours ago   133MB
lnmp-mysql   v1        95be68fa0d85   22 hours ago   449MB

五、启动容器

1.创建lnmp网络

docker network create lnmp

2.启动PHP

  • 挂载目录与nginx指定目录一致,若没有会自动创建
docker run -d -v /code/wordpress/:/code/wordpress/ --name php --net=lnmp lnmp-php:v1

3.启动Nginx

docker run -d -p 8080:80 -v /code/wordpress/:/code/wordpress/ --name nginx --net=lnmp lnmp-nginx:v1

5.启动mysql

[root@docker1 nginx] docker run -d --network=lnmp --name mysql lnmp-mysql:v1

5.查看启动状态

[root@docker1 ~] docker ps
CONTAINER ID   IMAGE           COMMAND                  CREATED       STATUS       PORTS                  NAMES
7310d595f462   lnmp-mysql:v1   "docker-entrypoint.s…"   2 hours ago   Up 2 hours   3306/tcp, 33060/tcp    mysql

e7c6d82d1d30   de9f843b40ab    "/docker-entrypoint.…"   2 hours ago   Up 2 hours   0.0.0.0:8080->80/tcp   nginx

4297b934a1ef   0f5aa301288b    "/usr/local/php/sbin…"   2 hours ago   Up 2 hours   9000/tcp               php

5.访问网站测试

  • wordpress注册登录页面
192.168.12.30:8080

六、上传镜像到GitHub

1.登录GitHub

[root@docker1 ~] docker login
···
Login Succeeded

2.打标签

[root@docker1 php] docker tag 0f5aa301288b 18954354671/php:lnmp-php-v1
[root@docker1 php] docker tag de9f843b40ab 18954354671/php:lnmp-nginx-v1
[root@docker1 php] docker tag 95be68fa0d85 18954354671/php:lnmp-mysql-v1

3.上传到GitHub

[root@docker1 php] docker push 18954354671/php:lnmp-php-v1
[root@docker1 php] docker push 18954354671/php:lnmp-nginx-v1
[root@docker1 php] docker push 18954354671/php:lnmp-mysql-v1

4.上传报错解决

  • 若上传过程出现如下报错,更改DNS地址重新上传即可
报错大致内容:
dial tcp: lookup auth.docker.io on 223.5.5.5:53: server misbehaving

方式一:无需重启
echo "nameserver 114.114.114.114" >> /etc/resolv.conf

方式二:需重启机器
sed -i 's#223.5.5.5#114.114.114.114#g' /etc/sysconfig/network-scripts/ifcfg-eth0
