Linux部署docker镜像之PHP项目的Dockerfile步骤

项目语言PHP7.4、MariaDB/MySQL、Nginx、Redis

　　

一、Dockerfile

FROM centos:7

MAINTAINER 作者姓名 邮箱 可忽略

#设置容器时间和宿主主机一致
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

#安装PHP7.4
RUN yum install epel-release -y
RUN rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
RUN yum --enablerepo=remi-php74 install php -y
RUN yum --enablerepo=remi-php74 install php-xml php-soap php-xmlrpc php-mbstring php-json php-gd php-mcrypt php-cli php-common php-redis php-ldap php-mysql php-mysqli php-pdo php-fpm php-devel php-zip php-opcache -y
RUN sed -i 's/^user\ =\ apache/user\ =\ nginx/' /etc/php-fpm.d/www.conf
RUN sed -i 's/^group\ =\ apache/group\ =\ nginx/' /etc/php-fpm.d/www.conf
RUN sed -i 's/^;listen\.owner\ =\ nobody/listen\.owner\ =\ nobody/' /etc/php-fpm.d/www.conf
RUN sed -i 's/^;listen\.group\ =\ nobody/listen\.group\ =\ nobody/' /etc/php-fpm.d/www.conf
RUN sed -i 's/^;listen\.mode\ =\ 0660/listen\.mode\ =\ 0660/' /etc/php-fpm.d/www.conf

#安装Nginx
RUN yum install nginx -y
#复制项目Nginx配置
COPY ./website.conf /etc/nginx/conf.d/website.conf

#复制项目
RUN mkdir -p /var/www/website
COPY ./website/ /var/www/website
COPY ./init.sh /var/www/website/init.sh
RUN chmod -R 777 /var/www/website
RUN ln -s /var/www/website/admin/upload /var/www/website/api/upload

 

二、Docker部署步骤
1、项目编译成镜像 请cd到和Dockerfile同目录; 例如：cd /home/docker
    docker build -t website:latest .

2、查看镜像并创建容器
    docker images
    
    #端口8081在website.conf中设定
    #--privileged是给权限 不然进入容器systemctl命令没有权限
    #-v /home/docker/upload:/var/www/website/admin/upload 路径需要根据项目目录而定 上传的附件映射到宿主主机
    #-v /sys/fs/cgroup:/sys/fs/cgroup 解决权限问题
    #/usr/sbin/init 解决权限问题 不能省略
    docker run -it -p 8089:8081 --privileged --name web-site -v /home/docker/upload:/var/www/website/admin/upload -v /sys/fs/cgroup:/sys/fs/cgroup -d website:latest /usr/sbin/init

3、查看容器
    docker ps -a
    
4、进入容器并启动服务
    docker exec -it web-site /bin/bash
    /var/www/website/init.sh

5、查看容器运行日志
    docker logs -f web-site

6、查看容器接口情况
    curl http://127.0.0.1:8081/api/index.php/common/faqCate

7、查看宿主接口情况
    curl http://127.0.0.1:8089/api/index.php/common/faqCate
