DockerFile部署wordpress实践

部署wordpress

# 创建dockerfile目录
[root@docker02 ~]# mkdir /Dockerfile

# 进入dockerfile目录
[root@docker02 ~]# cd /Dockerfile

# 编写Docker File
[root@docker02 Dockerfile]# vim Dockerfile

# 复制wordpress配置文件
COPY wp.conf /etc/nginx/conf.d/

# 设置环境变量
ENV PATH=/app/mysql/bin:$PATH
ENV PHP_FPM_CONF_FILE=/etc/php-fpm.conf
ENV NGINX_CONF_FILE=/etc/nginx/nginx.conf

# 创建wordpress用户并复制 MySQL 配置文件
COPY my.cnf /etc/my.cnf
RUN /etc/init.d/mysqld start && \
    /app/mysql/bin/mysql -e "create database wp charset utf8;" && \
    /app/mysql/bin/mysql -e "grant all on wp.* to wp_user@'%' identified by '123';"
# 创建数据目录
VOLUME /app/mysql/data

# 暴露 MySQL 端口
EXPOSE 3306 80

# 启动服务
CMD service mysqld start && nginx -c $NGINX_CONF_FILE && php-fpm -c $PHP_FPM_CONF_FILE

准备Dockerfile所需文件

# mysql配置文件
[root@docker02 Dockerfile]# cat my.cnf 
[mysqld]
basedir=/app/mysql
datadir=/app/mysql/data

# wordpress数据文件
[root@docker02 Dockerfile]# cat wp.sql

开始制作成镜像

# 使用docker build执行dockerfile并指定镜像名与标签，最后的点是当前目录
[root@docker02 Dockerfile]# docker build -t wordpress:1 .

# 使用docker run运行并进入容器
[root@docker02 Dockerfile]# docker run --rm --name wordpress -p 80:80 -it wordpress:1 bash
## 启动mysql
[root@d1fd726876f9 app]# /etc/init.d/mysqld start
## 启动nginx
[root@d1fd726876f9 app]# nginx -c /etc/nginx/nginx.conf
## 后台启动php-fpm
[root@d1fd726876f9 app]# php-fpm -c /etc/php-fpm.conf &

访问网页

将wordpress打包成镜像

# 将容器制作成镜像
[root@docker02 ~]# docker commit d1fd726876f9 wordpress:v1

# 导出镜像
[root@docker02 ~]# docker save wordpress:v1 > /opt/wordpress.tgz

# 拷贝镜像
[root@docker02 ~]# scp /opt/wordpress.tgz 172.16.1.101:/opt

# 导入镜像
[root@docker01 ~]# docker load < /opt/wordpress.tgz

# 启动
[root@docker01 ~]# docker run --rm --name wordpress -p 80:80 -it wordpress:v1 bash
## 启动mysql
[root@0e5546c39cb7 app]# /etc/init.d/mysqld start
## 启动nginx
[root@0e5546c39cb7 app]# nginx -c /etc/nginx/nginx.conf
## 后台启动php-fpm
