环境部署

设备：CentOS7，192.168.118.33（博主这里在一台设备上部署）

关闭防火墙，核心防护

[root@localhost ~]# hostnamectl set-hostname docker_lnmp
[root@localhost ~]# su
[root@docker_lnmp ~]# systemctl stop firewalld
[root@docker_lnmp ~]# systemctl disable firewalld
[root@docker_lnmp ~]# setenforce 0

安装docker源，安装docker

[root@docker_lnmp ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
[root@docker_lnmp ~]# 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
[root@docker_lnmp ~]# yum install -y docker-ce
[root@docker_lnmp ~]# systemctl start docker
[root@docker_lnmp ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

[root@docker_lnmp ~]# mkdir docker && cd docker
[root@docker_lnmp docker]# yum install -y tree

部署LNMP

在docker目录创建nginx和mysql目录，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等包到两个目录下

[root@docker_lnmp docker]# mkdir nginx mysql
[root@docker_lnmp docker]# cd nginx/
[root@docker_lnmp nginx]# touch Dokcerfile
##分别解压，结果如下
[root@docker_lnmp docker]# tree -L 2
