使用dockerfile以及docker compose部署搭建wordpress平台-Toy模板网

这篇具有很好参考价值的文章主要介绍了使用dockerfile以及docker compose部署搭建wordpress平台。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

一.什么是dockerfile

Dockerfile 是一个文本文件，其中包含了构建 Docker 镜像的指令。它描述了镜像的构建过程，包括基础镜像、安装的软件、配置信息等。

Dockerfile 以指令的形式定义了构建镜像的步骤，每一行指令都是一个独立的步骤。这些指令可以包括从官方仓库获取基础镜像、运行命令、添加文件、设置环境变量等。

二.什么是docker compose

docker compose是 Docker 公司提供的一种用于定义和运行多容器应用的工具。它允许用户通过一个简单的 YAML 文件来描述应用的各个服务，并一次性启动或停止整个应用。

三.编写dockerfile

制作nginx的镜像：
#指定基础镜像
FROM daocloud.io/library/centos:7
#指定作者
LABEL maintainer="kingshot" build-time="2024-01-01" project="wordprees"
#RUN用来执行shell命令
RUN yum -y install epel-release
RUN yum -y install nginx
#copy用来将宿主机的内容拷贝到镜像
#ADD等同于COPY,但是不同在于ADD可以拷贝网络资源；ADD可以在拷贝压缩包是，可以将解压缩的内容拷贝到镜像中
COPY ./nginx.conf /etc/nginx/nginx.conf
#指定服务端口
EXPOSE 8080
#指定卷
VOLUME ["/usr/share/nginx/html"]
#ENV设置环境变量
ENV nginx_level=1.16.1
#夯住
CMD ["nginx","-g","daemon off;"]

四.制作wordpress镜像

[root@host1 ~]# mkdir /root/wordpress

[root@host1 ~]# cd wordpress/

[root@host1 wordpress]# vim Dockerfile

[root@host1 wordpress]# mv /root/wordpress-5.9.1-zh_CN.tar.gz /root/wordpress

[root@host1 wordpress]#mv /etc/nginx.conf /root/wordpress/nginx.conf

FROM daocloud.io/library/centos:7
LABEL  maintainer="kingshot" build-time="2024-01-01" project="wordpress"
RUN yum -y install epel-release
RUN yum -y install nginx
RUN yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm
RUN yum install -y php80-php-xsl php80-php php80-php-cli php80-php-devel php80-php-gd php80-php-pdo php80-php-mysql php80-php-fpm
ADD  wordpress-5.9.1-zh_CN.tar.gz /usr/share/nginx/
COPY ./nginx.conf /etc/nginx/nginx.conf
EXPOSE 80
COPY start.sh /
ENTRYPOINT ["sh","/start.sh"]

制作启动脚本：

[root@host1 wordpress]# vim start.sh

chmod 777 /usr/share/nginx/wordpress -R
nginx && /opt/remi/php80/root/usr/sbin/php-fpm
if [ $? -eq 0 ];then
echo "nginx和php启动成功"
else echo "启动失败"
fi
tailf /var/log/nginx/*

nginx配置文件：

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 4096;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.

server {
        listen      80;
        server_name root;
        location / {
			root /usr/share/nginx/wordpress;
			index index.php;
		}
        location ~ \.php$ {
            root          /usr/share/nginx/wordpress;  #指定网站目录
            fastcgi_pass   127.0.0.1:9000;    #指定访问地址
            fastcgi_index  index.php;		#指定默认文件
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name; #站点根目录，取决于root配置项
            include        fastcgi_params;  #包含nginx常量定义
        		}
        }

# Settings for a TLS enabled server.
#
#    server {
#        listen       443 ssl http2;
#        listen       [::]:443 ssl http2;
#        server_name  _;
#        root         /usr/share/nginx/html;
#
#        ssl_certificate "/etc/pki/nginx/server.crt";
#        ssl_certificate_key "/etc/pki/nginx/private/server.key";
#        ssl_session_cache shared:SSL:1m;
#        ssl_session_timeout  10m;
#        ssl_ciphers HIGH:!aNULL:!MD5;
#        ssl_prefer_server_ciphers on;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#    }

}

五.制作镜像并启动wordpress

[root@host1 wordpress]# docker build -t mywordpress:v1.0 .

[root@host1 wordpress]# docker run -itd -p 80:80 mywordpress:v1.0

六. 拉取并运行mysql5.7镜像

[root@host1 wordpress]# docker pull daocloud.io/library/mysql:5.7

[root@host1 wordpress]# docker run -itd -e MYSQL_ROOT_PASSWORD=123 -e MYSQL_DATABASE=wordpress daocloud.io/library/mysql:5.7

[root@host1 wordpress]# docker run -itd -p 80:80 mywordpress:v1.0

七.制作docker compose

[root@host1 wordpress]# vim Docker compose.yaml

version: '3'
services:
  wordpress:
    build: .
    container_name: wordpress-web
    ports:
      - "80:80/tcp"
      - "443:443/tcp"
    links: 
      - database:wordpress.db.com
    depends_on:
      - database
  database:
    image: daocloud.io/library/mysql:5.7
    container_name: wordpress-db
    environment:
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_DATABASE=wordpress
   #选择挂载路径
    volumes:
      - /root/wordpress/data:/var/lib/mysql
