WordPress Web development in AWS

构建后台

没事不要执行该代码

cd ~/Documents/web/key_aws
ssh ubuntu@3.124.205.43 -i pass1aws.pem
sudo apt update -y
sudo apt upgrade -y
sudo apt install apache2
sudo systemctl status apache2
sudo systemctl enable apache2
sudo apt install mariadb-server mariadb-client
sudo systemctl start mariadb
sudo systemctl status mariadb
sudo mysql_secure_installation ...
sudo systemctl restart mariadb
sudo apt install php php-mysql php-gd php-cli php-common
sudo apt install wget unzip
sudo wget https://wordpress.org/latest.zip
sudo unzip latest.zip
sudo cp -r wordpress/* /var/www/html/
cd /var/www/html/
sudo chown www-data:www-data -R /var/www/html/
sudo rm index.html 
## Now go to the IP webseit, when need database, do so
sudo mysql -u root -p
Enter
##  create database wordpress;
create database wordpress;
create user "wpadmin"@"%" identified by "wpadminpw";
grant all privileges on wordpress.* to "wpadmin"@"%";
exit;

back to the IP webseit, pass the database , username and password, set username and password for wordpress, 到此，可以用IP 地址访问前端和后台了

解析域名

route53, 用域名创建NS A-IPV4,名称为空， 值为IP CNAME，名称www, 值为域名 再将A 和CNAME 放到namecheap的域名的DNS管理中

ssl

sudo a2enmod ssl
sudo systemctl restart apache2
cd ~
wget https://dl.eff.org/certbot-auto
chmod a+x certbot-auto
sudo ./certbot-auto --apache....

go to https://www.sslshopper.com/ssl-checker.html and check you domina

scp

transfer file to linux instance of CE2

scp -i pass1aws.pem init.el ubuntu@3.124.205.43:.emacs.d

external html

  • 将文件传到部署根目录
  • 复制文件xxx.html 为page-xxx.php到应用主题根目录
  • 创建页面，先只写标题，保存后改别名，slug 为xxx
  • 发布后，将页面设为菜单就能访问

webbuild.png

appeared Problem

server is not startup

1, workspace 有重叠和包含， 2, 需要重启 lsp mode

can't find the main class to start project

mvn compile 出现问题，大多数时候是依赖的问题

没有对应的补全

mvn 依赖的version 不同会有不同的包，补全也不同

MySQL

事务隔离

1 可同时访问修改 脏读 2 隔离访问 不可重返读 3 单人访问 幻读

single java file connect to mysql

1.download the driver to a current to java file

official web, and in my case

mysql-connector-java-8.0.20.jar

2.add the current path to the CLASSPATH

export CLASSPATH=mysql-connector-java-8.0.20.jar:.

3.compile and connect

execute as a jar file

if I want to package them to a package to a jar starkoverflow hitting and this plugin to pom.xml

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

and run with : mvn clean compile assembly:single

and then mvn package

can be called by jar file

java -cp target/xxxx....xx.jar com.mycompany.app.App

springboot

just call the plugins at the start

事务 Transaction

声明式：Annoation
1, 配置事务管理器
2, 开启事务注解
3, 添加事务注解
@Transaction(propagation, isolation, timeout, readout, (no)rollback)
propagation;事务是否传播
isolation:
脏读：未提交的事务读取到另一个未提交的事务的原始数据
不可重复读；未提交的事务读取到另一个提交的事务的原始数据
幻读；未提交的事务读取到另一个提交的事务的修改数据

范式

原子性 一致性 隔离性 持久性

连接池

外键

多表

execute in emacs

  1. create mvn project
  2. find the plugin of mysql and add it to pom.xml
  3. programmierung
  4. the connection can be call in the dabug of emacs

sudo mv /var/lib/dpkg/info/ubuntu-advantage-tools.* /tmp/
sudo dpkg --force-remove-reinstreq --purge ubuntu-advantage-tools
sudo dpkg --remove --force-remove-reinstreq ubuntu-advantage-tools

then

sudo apt update
sudo apt upgrade
sudo apt install yarn
yarn --version

new version can be shown, and yarn init works

Spring

sammelung:

Component inject the class into Spring from current file as bean ComponentScan load the bean into current file from Spring as class Autowired complete all beans dependence with the beans in spring Configuration configuration class

模式： 单例和多例：生命周期：创建和销毁时间

Annotation mehthod

@Component

将所修饰的类做成bean，由 Spring 来管理 为了减少耦合，建立一个配置类来管理全部的bean 由 @Configuation and @ComponentScan 创建的配置类来管理。 注意Spring只是默认管理@ComponentScan所在的其以下的区域， 除非指定包名，可以到其上一级的包路径

web hierarchy with @component

Controller layer use @Controller than @Component Service layer use @Service than @Component Dao layer use @Repository than @Component

autowired

  • Set注入 利用set方法
  • cost注入 利用构造方法，可和set 注入混用
  • 普通成员变量
  • 普通成员函数

interface with @Autowired

注入 @Compenten 加在实现类 装配 @Autowired 放在该接口的类型前 产生歧义 多个Autowired 如果该接口有多个实现类，不知道用那个实现类的bean 首选bean @Primary 多个实现类的Compenten注入时，可制定唯一一个实现类为首 限定附 @Qualifier("xxx") 在Autowired时，使用一样的 @Qualifier("xxx") bean id @Compenten("xxx") 同样在Autowired时，使用一样的 @Qualifier("xxx") 默认bean id xxx即为类名 在Autowired时 @Qualifier("xxx")时，类名首字母小写即可 二合一 @Resource(name="小写类名") 代替Autowired 和Qulifier()

xml mehthod

New-> XML Configuration File -> Spring Config default name: ApplicationContext.xml

<bean class="xxx.xxx.xxx.class" id="" (gleich wie name="") 别名可以多个，隔开即可 <consturctor-arg ref="beanid"> für contributor bean <consturctor-arg name="xxx" value="yyy"> für contributor string c:contributor C名称空间 <list> <map> <set> <p> <util> <properties> ... ><bean>

bean method

Don't use @Component or Service Controller Repository to inject bean(IOC) with a config class @Configuation Use @bean on it's consturctor function to inject bean. 对其多实现类的歧义性处理，和自动装配一样，@Primary @Qualifer and BEANID

seter

passing the contributor bean can use setter function

consturctor

if a bean need another bean as contributor, the contributor can be passed as argument into consturctor function, or generated

advancd mehthod

function field

singleton default only one bean prototype scope="prototype" Session each inject request

lazy load bean

in xml: lazy-init="true" in Annotation: @Lazy with prototype, singleton is default as lazy

init and destroy

log4j

Concept

连接点：可增强的方法 切入点: 实际上被增强的方法 通知（增强）：增强的内容

  • 前置 Before
  • 后置 After 增强之后，return 之前，有异常也执行
  • 环绕 Around
  • 异常 AfterThrowing 有异常才执行
  • 最终 AterRreturning return 之后才执行，有异常不执行

切面：将增强内容应用到切入点

local Nginx deployment

install

yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel


tar
mv xxx nginx
mv nginx /usr/local/src/
cd /usr/local/src/nginx
mkdir /usr/nginx
./configure --prefix=/usr/nginx
make
make install

sudo apt install nginx

etc/nginx 是其配置文件夹，里面有很多include文件， nginx 的默认设置在其中一个 default 文件里。 本机html仓库 /var/www/html 将项目放在此文件夹下，运行对于的端口即可 本机开机后,该文件的会被自动部署,端口可见

fire wall 80 port if necessary

add port :
sudo apt install firewalld
sudo firewall-cmd --add-port=80/tcp --permanent
sudo firewall-cmd --remove-port=80/tcp --permanent
restart firewall:
sudo  firewall-cmd --reload
check port:
sudo  firewall-cmd --list-all

nginx control

sudo apt systemctl stop nginx
nginx -s stop
sudo apt systemctl start nginx
nginx -s reload

uninstall

sudo apt-get purge nginx nginx-common

Nginx with php

sudo apt install nginx sudo systemctl restart nginx sudo apt install php sudo apt install php-fpm check if exit: /var/run/php/php7.2-fpm.sock

emacs /etc/php/7.2/fpm/pool.d/www.conf -> listen = /run/php/php7.2-fpm.sock

cd /etc/nginx/sites-available emacs default

Maven

package all the dependencies together as a jar

if I want to package them to a package to a jar starkoverflow hitting and this plugin to pom.xml

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

package and Execute

  • run with : mvn clean compile assembly:single
  • mvn package

and now this jar file can be called

  • java -cp target/xxxx....xx.jar com.mycompany.app.App

customize locally archetype

to the local repository

cd ~/.m2/repository/org/apache/maven/archetypes/maven-archetype-quickstart/1.4/

open the jar file, and change the pom.xml

Session und Cookie

  1. Browser send request to server with name, password...
  2. if the authentication is passed, server generate a SessionID,

and search the results, giving back browser response(name, password, results Sessionid..) Sessionid will be saved in SERVER.

  1. get the response, browser save the name, password and Sessionid as

Cookie.

  1. send request again, browser get the name, password, and Sessionid from Cookie, and send the requests
  2. server check the Sessionid only if possible, and send the results and name, password again as response back to browser.

Only the first time response, Sessionid will be send back to browser.

URL重写（常用），就是把session id直接附加在URL路径的后面

HTTP Proposal

http Request

Request Line request type + url path(many kinds of paramenters)+ http version Header: Host; Cookie; Content-type; User-Agent... Request Body: username="admin"&password="admin"

Http Response

esponse Line: http version + state code + state string Header: Content-type (describe information) Response Body: <html> ....</tml>

appeared Problem

server is not startup

1, workspace 有重叠和包含， 2, 需要重启 lsp mode

can't find the main class to start project

mvn compile 出现问题，大多数时候是依赖的问题

没有对应的补全

mvn 依赖的version 不同会有不同的包，补全也不同
