使用Docker部署lnmp和wordpress

主机	IP地址	操作系统
Docker	192.168.20.11	Cenos 7

• ps：资源可以在csdn资源中搜索

php-5.5.38.tar.gz        mysql-5.6.36.tar.gz
nginx-1.12.2.tar.gz        libmcrypt-2.5.7.tar.gz           wordpress-4.9.4-zh_CN.tar.gz

我这里是提前解压然后一股脑上传到xshell的

环境以及docker的安装

[root@localhost ~]# hostnamectl set-hostname docker     //修改主机名
[root@localhost ~]# su

[root@docker ~]# setenforce 0
[root@docker ~]# yum clean all && yum makecache             //清空repo源并重载

• 安装docker源

[root@docker ~]# yum -y install yum-utils device-mapper-persistent-data lvm2    
[root@docker ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
已加载插件：fastestmirror, langpacks
adding repo from: https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo

• 安装docker并启动

[root@docker ~]# yum -y install docker-ce         //下载docker

[root@docker ~]# systemctl start docker          //启动docker
[root@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.
[root@docker ~]# systemctl daemon-reload       //启动守护进程
[root@docker ~]# systemctl restart docker       //重启docker

• 按照下方树放入对应的安装包并解压

[root@docker docker]# mkdir docker && cd docker         //创建docker工作目录
[root@docker docker]# yum -y install tree            //下载工具
[root@docker docker]# tree -L 2
