一 .TASK

创建2台EC2实例，一台名为「ec2-repo」，用作开发环境，将编写好的代码提交至repository(需安装git)，一台名为「ec2-wp」,需要通过user data预安装code deploy agent，通过Code Deploy将应用程序部署至「ec2-wp」

二. 环境准备

IAM

创建用户组，将IAM权限赋予给该组
用户组下创建一名用户，生成credential，用于后续代码提交凭证
在这里插入图片描述
创建角色，用于后期的CodeDploy

创建存储库

在这里插入图片描述

ec2-repo

创建ec2实例（全流量安全组）
链接到此实例下载 wordpress 包

# wget https://s3-us-west-2.amazonaws.com/us-west-2-awstraining/courses/spl-82/v1.4.5.prod-2bbeba30/scripts/WordPressmaster.zip
# unzip WordPress-master.zip -d /tmp/WordPress_Temp
# mkdir -p /tmp/WordPress
# cp -paf /tmp/WordPress_Temp/WordPress-master/* /tmp/WordPress
# rm -rf /tmp/WordPress_Temp
# rm -f WordPress-master.zip
# mkdir -p /tmp/WordPress/scripts

创建 install_dependencies.sh

vi /tmp/WordPress/scripts/install_dependencies.sh
#!/bin/bash
yum install -y httpd wget php-fpm php-mysqli php-json php php-devel mariadb105-
server

创建 start_server.sh

vi /tmp/WordPress/scripts/start_server.sh
#!/bin/bash
systemctl start httpd
systemctl enable httpd
systemctl start mariadb
systemctl enable mariadb

创建 stop_server.sh

vi /tmp/WordPress/scripts/stop_server.sh
#!/bin/bash
isExistApp=`pgrep httpd`
if [[ -n $isExistApp ]]; then
 systemctl stop httpd
fi
isExistApp=`pgrep sql`
if [[ -n $isExistApp ]]; then
 systemctl stop mariadb
fi

创建数据库脚本

vi /tmp/WordPress/scripts/create_test_db.sh
#!/bin/bash
mysql -uroot <<CREATE_TEST_DB
CREATE DATABASE IF NOT EXISTS test;
CREATE_TEST_DB

创建 change_permissions.sh 脚本

vi /tmp/WordPress/scripts/change_permissions.sh
#!/bin/bash
chmod -R 777 /var/www/html/WordPress

修改文件属性

chmod +x /tmp/WordPress/scripts/*
ls -la /tmp/WordPress/scripts

创建 vi /tmp/WordPress/appspec.yml 文件

version: 0.0
os: linux
files:
 - source: /
 destination: /var/www/html/WordPress
hooks:
 BeforeInstall:
 - location: scripts/install_dependencies.sh
 timeout: 300
 runas: root
 AfterInstall:
 - location: scripts/change_permissions.sh
 timeout: 300

 ApplicationStart:
 - location: scripts/start_server.sh
 - location: scripts/create_test_db.sh
 timeout: 300
 runas: root
 ApplicationStop:

 runas: root

将 wordpress 代码，appspec.yml 和 script 文件夹都 git push 到仓库中

ec2-wp

创建ec2实例，预设置如下userdata，安装code deploy agent

#!/bin/bash
yum install ruby -y 
aws s3 cp s3://aws-codedeploy-ap-northeast-2/latest/install . --region ap-northeast-2 
chmod +x install
./install auto
