使用docker搭建WordPress博客

一、前置条件

主机：20.0.0.142
安装docker

docker的安装见此篇文章：Linux企业应用——Docker（一）之初步了解Docker以及Docker的安装

二、拉取镜像

docker pull wordpress:latest
docker pull mysql:5.7

三、安装工具及依赖

1.安装

wget准备yum源，此处使用aliyun提供的源
yum -y install python2-pip准备pip工具，用于批量管理python语言开发的工具包
yum -y install gcc libffi-devel python-devel openssl-devel openldap-devel安装依赖

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum -y install python2-pip
yum -y install gcc libffi-devel python-devel openssl-devel openldap-devel

2.升级pip

# 升级pip:
sudo wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
sudo python get-pip.py
pip -V

3.获取docker-compose

#安装
sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.26.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
#授权
sudo chmod +x /usr/local/bin/docker-compose
#查看
docker-compose --version

方法一

使用yaml文件直接进行配置

mkdir /root/wordpressproject
cd /root/wordpressproject/

[root@server1 wordpressproject]# vi docker-compose.yaml
[root@server1 wordpressproject]# cat docker-compose.yaml
version: '3.3'
service:
   db:
     image: mysql:5.7
     restart: always
     enviroment:
       MYSQL_ROOT_PASSWORD: somewordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress
   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "8000:80"
     restart: always
     enviroment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
       WORDPRESS_DB_NAME: wordpress

另一种方法（推荐）

创建wp-mysql容器启用mysql镜像

[root@server1 wordpressproject]# docker run --name wp-mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306           -d mysql:5.7
7165fc9f14469e651a28dfe93fa5442d087132f780cf7b986a3b029e94c5c3aa

创建数据库

docker exec -it wp-mysql /bin/bash

mysql -uroot -p123456
create database wordpress;

如下：

[root@server1 wordpressproject]# docker exec -it wp-mysql /bin/bash
bash-4.2# mysql -uroot -p123456
mysql: [Warning] Using a password on the command line interface can be insecure.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> create database wordpress;
Query OK, 1 row affected (0.00 sec)

mysql> exit

四、创建容器，启用镜像，映射端口

docker run --name myWordpress --link wp-mysql:mysql -p 8080:80 -d wordpress
创建一个基于wordpres:latest镜像，名为myWordpress的容器，并立即启动，映射到8080端口，连接到mysql
如果的端口被占用，使用netstat -anp | grep 端口号查看，最后kill 进程号，删除原来容器后再次创建

[root@server1 wordpressproject]# netstat -anp | grep 8080
[root@server1 wordpressproject]# docker remove myWordpress
myWordpress
[root@server1 wordpressproject]# docker run --name myWordpress --link wp-mysql:mysql -p 8080:80 -d wordpress

五、访问并设置

浏览器访问20.0.0.142:8080

选择简体中文

输入命令设置的信息
设置用户名和密码

登录

成功
