镜像部署 WordPress 个人站点
使用 WordPress 镜像一键创建实例，免去繁琐的安装步骤。
使用场景
WordPress 是一款使用 PHP 语言开发的博客平台，您可使用通过 WordPress 搭建属于个人的博客平台。
本文以 CentOS 7.6 操作系统的CSDN开发云云主机为例，通过镜像部署 WordPress 个人站点。
操作步骤
步骤1：登录云服务器
参照文档登录 Linux 主机
步骤2：安装Docker
- 依次执行以下命令，添加 yum 源。
yum updateyum updateyum update
1
yum <span class="token function">install</span> epel-release -yyum <span class="token function">install</span> epel-release -yyum install epel-release -y
1
yum clean allyum clean allyum clean all
1
yum listyum listyum list
1
- 执行以下命令，安装 Docker。
yum <span class="token function">install</span> docker-io -yyum <span class="token function">install</span> docker-io -yyum install docker-io -y
1
- 执行以下命令，运行 Docker。
systemctl start dockersystemctl start dockersystemctl start docker
1
- 执行以下命令，检查安装结果。
docker infodocker infodocker info
1
返回如下信息，即表示安装成功。
步骤3: 设置docker开机启动
设置docker开机启动
systemctl enable docker.servicesystemctl enable docker.servicesystemctl enable docker.service

步骤4：安装 docker-compose
安装 docker-compose
yum <span class="token function">install</span> <span class="token function">docker-compose</span> -yyum <span class="token function">install</span> <span class="token function">docker-compose</span> -yyum install docker-compose -y
1
查看版本
<span class="token function">docker-compose</span> version<span class="token function">docker-compose</span> versiondocker-compose version
1
看到如下信息表示 docker-compose安装成功
步骤5: 安装 WordPress
准备目录
您需要创建在/var目录下创建一个名为wordpress的新目录来存放 WordPress 数据。这样我们就实现了一定的数据持久化。
<span class="token function">mkdir</span> -p /var/wordpress <span class="token builtin class-name">cd</span> /var/wordpress<span class="token function">mkdir</span> -p /var/wordpress <span class="token builtin class-name">cd</span> /var/wordpressmkdir -p /var/wordpress cd /var/wordpress

创建 docker-compose.yml 文件。

这里解释一下docker-compose.yml文件：
- 定义了两个服务:
db和wordpress - 使用Docker镜像安装MySQL 5.7 和 最新版WordPress
- db environment 指定了数据库的用户名和密码
- wordpress environment 指定了wordpress数据库的配置
- WordPress默认运行在容器的80端口，我们将它映射到本地计算机的8000端口
启动wordpress服务
<span class="token function">docker-compose</span> up -d<span class="token function">docker-compose</span> up -ddocker-compose up -d
1
在本地浏览器中访问 http://云服务器实例的公网IP:8000，开始安装 WordPress 网站
-
选择 WordPress 语言后，单击 继续。
-
在页面中按需输入 WordPress 站点标题、管理员用户名、管理员密码及电子邮件，单击安装WordPress
所需信息 说明 站点标题 WordPress 网站名称。 用户名 WordPress 管理员名称。出于安全考虑，建议设置一个不同于 admin 的名称。因为与默认用户名称 admin 相比，该名称更难破解。 密码 可以使用默认强密码或者自定义密码。请勿重复使用现有密码，并确保将密码保存在安全的位置。 您的电子邮件 用于接收通知的电子邮件地址。
在页面中查看到安装成功提示即表示已完成安装。如下图所示：
现在可以登录 WordPress 博客，并开始发布博客文章了。
可以使用以下命令管理wordpress的服务
<span class="token function">docker-compose</span> stop <span class="token function">docker-compose</span> start <span class="token function">docker-compose</span> down <span class="token function">docker-compose</span> down --volumes<span class="token function">docker-compose</span> stop <span class="token function">docker-compose</span> start <span class="token function">docker-compose</span> down <span class="token function">docker-compose</span> down --volumesdocker-compose stop docker-compose start docker-compose down docker-compose down --volumes
