附录：中间件与环境安装文档

1. LAMP 环境

LAMP: Linux + Apache + MySQL + PHP；是php网站开发的基础环境。

前置：

• 1、开通ecs
• 2、centos7.9版本
• 3、可访问公网
• 4、安全组放行 80，3306 端口

1. 安装Apache+PHP

# 安装 Apache
yum install -y httpd
# 启动 Apache 服务 & 设置开机启动
systemctl start httpd

# 安装php7.3
## 运行以下命令，添加EPEL源。
yum install -y https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum install -y --enablerepo=remi-php73 php php-fpm php-mysqlnd php-cli
#重启httpd服务
systemctl restart httpd

测试PHP是否安装成功

vim /var/www/html/info.php
#内容如下
<?php
phpinfo();
?>

#重启服务器
systemctl restart httpd

#访问 http://你的ip/info.php； 出现下面页面则代表php安装成功

2. 安装MySQL

#准备目录
mkdir -p /opt/db
cd /opt/db/

### 安装 MySQL 5.6：
wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
rpm -ivh mysql-community-release-el6-5.noarch.rpm
yum repolist all | grep mysql
yum install mysql-community-server -y

#启动mysql
systemctl start mysqld


#初始化mysql，一路yes即可，要记住自己新设置的密码
mysql_secure_installation


#创建初始数据库&授予权限
mysql -uroot -p
create database db_wordpress character set utf8 collate utf8_bin;
grant all on db_wordpress.* to user_wp@'localhost' identified by '123456';
grant all on db_wordpress.* to user_wp@'%' identified by '123456';

2. Java环境

#下载jdk17
wget https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.tar.gz
#安装上传工具 以后使用命令 rz  选中文件进行上传
yum install -y lrzsz

#解压
tar -xzvf jdk-17_linux-x64_bin.tar.gz

#移动到指定位置； 记住全路径： /usr/local/jdk-17.0.7
mv jdk-17.0.7 /opt/

#配置环境变量   /opt/jdk-17.0.2
vim /etc/profile

#在最后加入下面配置，注意修改 JAVA_HOME位置为你自己的位置
export JAVA_HOME=/opt/jdk-17.0.2
export PATH=$JAVA_HOME/bin:$PATH

#使环境变量生效
source /etc/profile

#验证安装成功
java -version

3. WordPress安装

#下载 
mkdir -p /opt/WP
cd /opt/WP
# wget https://cn.wordpress.org/latest-zh_CN.tar.gz
# tar -xzvf latest-zh_CN.tar.gz

wget https://cn.wordpress.org/wordpress-6.2-zh_CN.tar.gz

 tar -xzvf wordpress-6.2-zh_CN.tar.gz
# 下载最新版的wordpress：最新版和 redis以及CDN分发加速的插件不兼容




#把word_press代码复制到 /var/www/html 下，/var/www/html是php的网站目录
cd /var/www/html
cp -rf /opt/WP/wordpress/* /var/www/html/



###########配置 wordpress 访问 MYSQL
cd /var/www/html/
cp wp-config-sample.php wp-config.php
vim wp-config.php

##内容如下，注意修改为自己之前安装的MySQL的账号密码以及端口号

{
  "registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

3. MySQL、Redis安装

安装MySQL和Redis的compose文件

services:
  mysql:
    image: 'mysql:latest'
    restart: always
    environment:
      - 'MYSQL_DATABASE=mydatabase'
      - 'MYSQL_PASSWORD=secret'
      - 'MYSQL_ROOT_PASSWORD=verysecret'
      - 'MYSQL_USER=myuser'
    volumes:
      - /opt/mysql:/etc/mysql/conf.d #只要在外部的/opt/mysql目录下随便放一个 xx.cnf 文件，mysql自动把他当成配置文件
    ports:
      - '33066:3306'
  redis:
    image: redis:latest
    volumes:
      - /opt/redis/redis.conf:/usr/local/etc/redis/redis.conf
    command: redis-server /usr/local/etc/redis/redis.conf
    restart: always
    ports:
      - '7379:6379'
