安装docker

安装docker源

yum install -y yum-utils device-mapper-persistent-data lvm2		#依赖环境
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo		                                                    #docker源

安装docker

yum install -y docker-ce  #安装社区版docker
systemctl enable docker   #开机自启
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
systemctl start  docker   #启动

创建nginx-php 、mysq目录

mkdir docker && cd docker

创建创建nginx-php 、mysql目录
mkdir nignx mysql

创建nginx-dockfile、php

cd nginx
上传nginx-1.12.2.tar.gz、wordpress-4.9.4-zh_CN.tar、libmcrypt-2.5.7.tar.gz、nginx.conf、wp-config.php
tar zxvf wordpress-4.9.4-zh_CN.tar.gz
tar zxvf nginx-1.12.2.tar.gz
tar zxvf libmcrypt-2.5.7.tar.gz
tar zxvf php-5.5.38.tar.gz

部署nginx-php

docker build -t "centos:nginx-php" .   #构建nginx-php镜像

docker images   #列出镜像
docker run -dit -p 80:80 -m 500m --memory-swap 1G 07a4acbb016b /bin/bash  #容器能使用的内存和交换分区大小
docker ps        #查看当前运行容器
docker exec -it [CONTAINER ID]   /bin/bash  #进入容器
nginx  #开启服务
/etc/init.d/php-fpm start              #启动php
netstat -antp | grep nginx
netstat -antp | grep php    
exit 

创建mysql-Dockerfile

cd /docker/mysql
上传mysql-5.6.36.tar.gz软件包至目录内
tar xzvf mysql-5.6.36.tar.gz		#解压
vim Dockerfile
FROM docker.io/centos:7
RUN yum -y install gcc gcc-c++ make autoconf make cmake wget
RUN groupadd mysql; useradd -r -M -u 3306 -s /sbin/nologin -g mysql mysql

RUN echo -e '#!/bin/bash\\nexport PATH=$PATH:/usr/local/mysql/bin' >/etc/profile.d/mysql.sh
RUN source /etc/profile
EXPOSE 3306

构建mysql镜像和开启服务
docker build -t "centos:mysql-5.6" .
docker run -idt -p 3306:3306 --device-write-bps /dev/sda:10M 45949d7f9d2e /bin/bash
docker exec -it 04716b5e5b69  /bin/bash		#进入容器
/etc/init.d/mysqld start		#开启服务

进入数据库授权
mysqladmin -u root -p password		#创建数据库密码，123
mysql -uroot -p123 	##进入数据库
create database wordpress default charset utf8 COLLATE utf8_general_ci;	##创建wordpress 表
grant all privileges on wordpress.*  to 'wordpress'@'%' identified by '123' with grant option;	                      #授权
flush privileges;		      #刷新权限生效
exit		                  #退出数据库、退出容器

测试访问网页wordpress

http://192.168.220.35/wordpress/index.php

备份

将所有容器快照
docker ps		                            #查询容器  
docker images		                        #查询镜像
docker export 04716b5e5b69 > test.tar		#导出备份
docker export 95e2167b5a54 > test1.tar
cat test1.tar | docker import - centos:new	#导入
docker images

将镜像保存成tar包
docker save -o mysql.tar centos:mysql-5.6
docker save -o nginx-php.tar centos:nginx-php
docker ps
docker stop [容器id]	#停止容器
docker rm [容器id]		#删除容器
docker rmi [镜像id]		#删除镜像
docker images		    #nginx-php已恢复
