我用的centos7.5 .1804
一、通过 RPM 安装 docker 17.03.0 版本并且配置 docker 阿里加速
安装依赖包
[root@centos7 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
配置docker yum源
[root@centos7 ~]# cat <<END >/etc/yum.repos.d/docker.repo [docker] name=docker baseurl = https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/7/x86_64/stable/ enabled=1 gpgcheck=0 END [root@centos7 ~]# yum clean all && yum makecache
查看docker 版本
[root@centos7 ~]# yum -y list docker-ce --showduplicates |sort -r
安装
[root@centos7 ~]# yum install docker-ce-17.03.0.ce-1.el7.centos
启用阿里镜像加速 【我的镜像加速 阿里云注册】
[root@centos7 ~]# mkdir -p /etc/docker [root@centos7 ~]# tee /etc/docker/daemon.json <<-'EOF' > { > "registry-mirrors": ["https://wjq8xgjg.mirror.aliyuncs.com"] > } > EOF [root@centos7 ~]# systemctl daemon-reload [root@centos7 ~]# systemctl restart docker
二、通过 docker 安装一个 LAPM 架构
查找lamp的镜像
[root@centos7 ~]# docker search -s 10 lamp Flag --stars has been deprecated, use --filter=stars=3 instead NAME DESCRIPTION STARS OFFICIAL AUTOMATED mattrayner/lamp A simple LAMP docker image running the prere… 240 [OK] linode/lamp LAMP on Ubuntu 14.04.1 LTS Container 178 tutum/lamp Out-of-the-box LAMP image (PHP+MySQL) 141 greyltc/lamp a super secure, up-to-date and lightweight L… 100 [OK] fauria/lamp Modern, developer friendly LAMP stack. Inclu… 93 [OK] lioshi/lamp Docker image for LAMP under debian 15 [OK] dgraziotin/lamp 11 [OK]
把第一个拉下来
[root@centos7 ~]# docker pull mattrayner/lamp
等……
[root@centos7 ~]# docker images mattrayner/lamp latest 05750cfa54d5 3 months ago 915MB
创建目录以及容器 并挂载到宿主机的目录到容器内
[root@centos7 ~]# mkdir /mysql_data [root@centos7 ~]# docker run -d --name=lamp -p 8080:80 -p 3306:3306 -v /mysql_data:/var/lib/mysql docker.io/mattrayner/lamp a58e4fe81f7cda319bdac3df7c5c60a413e75356c26ec3dd9766e59b5e2f2335
进入容器 初始化数据库
[root@centos7 ~]# mkdir /mysql_data [root@centos7 ~]# docker run -d --name=lamp -p 8080:80 -p 3306:3306 -v /mysql_data:/var/lib/mysql docker.io/mattrayner/lamp a58e4fe81f7cda319bdac3df7c5c60a413e75356c26ec3dd9766e59b5e2f2335 [root@centos7 ~]# docker exec -it lamp bash root@a58e4fe81f7c:/# mysql_secure_installation Securing the MySQL server deployment.

All done!
该镜像是基于ubuntu1804系统的
查看php mysql apache都是哪个版本
root@a58e4fe81f7c:~# dpkg -l
得知
php7.4 MySQL5.7.30 apache2.4.29
下载个包查看端口信息
root@a58e4fe81f7c:/# apt-get install net-tools
查看端口
root@a58e4fe81f7c:/# netstat -aptn Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN - tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 504/apache2
docker里面的host不能配置127.0.0.1 或者192.168.0.1 或则宿主机器将无法访问端口
root@a58e4fe81f7c:~# cd /var/www/html/ #测试页面 root@a58e4fe81f7c:/var/www/html# vim index.php <?php echo phpinfo(); ?>
访问
三、docker run 命令的延申指令，如怎么在停止一个 docker 容器的时候自动删除该容器
[root@centos7 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [root@centos7 ~]# docker run -it --rm centos bash [root@6cc822095ce4 /]# exit exit [root@centos7 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
四、docker run 命令在自动启动 docker 服务时 容器也自动启动
[root@centos7 ~]# docker run -d --name centos1 --restart=always centos
