Day 13 AWS云端实作起手式第三弹 开始拼拼图吧

今天接着来看看如何搞定架设的设定档吧!

步骤 7 建立网站
在先前开启EC2时，我们透过user data下载的内容，可以在EC2内确认架站内容。

User data的内容如下:

#!/bin/bash
yum update -y
yum install httpd php php-mysql -y
cd /var/www/html
echo "healthy" > healthy.html
wget https://wordpress.org/wordpress-5.1.1.tar.gz
tar -xzf wordpress-5.1.1.tar.gz
cp -r wordpress/* /var/www/html/
rm -rf wordpress
rm -rf wordpress-5.1.1.tar.gz
chmod -R 755 wp-content
chown -R apache:apache wp-content
wget https://s3.amazonaws.com/bucketforwordpresslab-donotdelete/htaccess.txt
mv htaccess.txt .htaccess
chkconfig httpd on
service httpd start

首先透过SSH登入EC2机器。pem档是建置EC2时，会取得的认证档。後面网址则是EC2机器的IP位址。

ssh -i "xxx.pem" [email protected]

进入EC2後，会先切换至root user模式，在特定路径下，确认网站服务可以正常运作。

# 转换至root user模式
sudo su
cd /var/www/html
# 确认htaccess是否已安装
cat .htaccess
service httpd start
service httpd status
# 检查系统的健康状态
cat healthy.html

步骤 8 登入网址
接着我们可以进入WP网站的後台，进行操作
http://ip_address/wp-admin/setup-config.php

针对DB的帐密来设定

接着回到EC2的console内，针对wp-config档案进行调整。

# 复制预设设定档
cp wp-config-sample.php wp-config.php
# 开始设定档编辑
nano wp-config.php

在wp-config.php内，编辑设定档。

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'database_name_here' );

/** MySQL database username */
define( 'DB_USER', 'username_here' );

/** MySQL database password */
define( 'DB_PASSWORD', 'password_here' );

/** MySQL hostname */
define( 'DB_HOST', 'localhost' );

/**#@+

define('AUTH_KEY',         '>J6IJ8Mq <,ql}<o),n/v4<*aCv~Xt1a{@gk{ +ddcqE?yvf9UkXA2p7l!}fs');

define('NONCE_SALT',       'M3%Yntih[Rh/VU.!7xO&Jl0 |oN$yO- fw^yYFY=e>UkQ|f* <nlT<4|`B');

完成设定档案之後，安装缺漏的档案，并查验服务是否可正常运行。

sudo amazon-linux-extras install -y lamp-mariadb10.2-php7.2 php7.2
sudo service httpd restart
