该博客详细介绍了如何在Docker环境下部署LNMP（Linux, Nginx, MySQL, PHP）服务，并安装WordPress。首先，通过关闭防火墙、设置DNS、更新repo源等步骤准备环境。然后，安装Docker源并创建Dockerfile来构建包含Nginx和PHP的镜像。接着，创建MySQL的Dockerfile并构建镜像。在容器内部启动Nginx和PHP-FPM服务，创建WordPress数据库并授权。最后，通过修改数据库密码和WordPress配置，完成WordPress的安装。访问指定URL即可查看WordPress页面。

环境部署

#关闭防火墙、核心防护
systemctl stop firewalld 
systemctl disable firewalld
setenforce 0

#添加DNS
echo "nameserver 114.114.114.114" /etc/resolv.conf

#重载repo源
yum clean all && yum makecache

#修改主机名
hostnamectl set-hostname docker-lnmp
su

1、安装docker源
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

2、安装docker
yum install -y docker-ce
systemctl start docker
systemctl enable docker

systemctl daemon-reload
systemctl restart docker

#创建dockerfile 目录
mkdir docker && cd docker

部署docker-lnmp

#创建nginx-php 、mysql目录
mkdir nignx mysql
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

修改数据库密码、进入数据库给wordpress提权

1、修改密码，第一行默认密码（无）第二、第三行新密码
mysqladmin -u root -p password
（第一行直接敲回车）
123456
123456

2、进入数据库、授权
mysql -uroot -p
123456 

#创建wordpress 表
create database wordpress default charset utf8 COLLATE utf8_general_ci;

#授权
grant all privileges on wordpress.*  to 'wordpress'@'%' identified by '123456' with grant option;

#刷新权限生效
flush privileges;

#退出数据库、退出容器
exit
exit
