传闻中天下第一的语言，试一下服务器部署，没想到这么困难，老古董还是有点难啊
先安装PHP，2021 年开始，Ubuntu 官方不再支持 PHP 5.6 版本的维护和更新，因此如果需要在 Ubuntu 上安装 PHP 5.6，则需要使用第三方的 PPA（个人软件包归档）来进行安装
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php5.6
php -v
PHP 5.6.40-78+ubuntu24.04.1+deb.sury.org+1 (cli)
Copyright (c) 1997-2016 The PHP Group
好像fpm不这么装也行，5.3.3以后集成了fpm，本身是用来管理的
apt-get install php5.6-fpm
systemctl status php5.6-fpm
检查apache服务启动
systemctl status apache2.service
内网地址，可以看到页面了
http://10.10.2.24/
替换一个PHP的index看下
<!DOCTYPE html>
<html>
<body>
<h1>我的第一个 PHP 页面</h1>
<?php
echo "Hello World!";
?>
</body>
</html>
到这里已经可以正常显示启动了
sudo apt install php5.6-mysql
docker pull mysql:5.6
docker run --name user_database -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 -d mysql:5.6
<?php
// 准备连接参数
$servername = "localhost";
$servername = "127.0.0.1";
$username = "root";
$password = "123456";
$dbname = "user_database";
// 创建数据库连接
$connect = mysqli_connect($servername, $username, $password, $dbname);
// 检查连接
if (mysqli_connect_error()) {
die("连接失败: " . mysqli_connect_error());
}
// 选择数据库
if (mysqli_select_db($connect, $dbname)) {
echo "数据库连接成功";
} else {
echo "数据库连接失败";
}
// 关闭连接
mysqli_close($connect);
?>
测试是否可以连接到数据库，目前没有问题了
Apache2和之前的不太一样，配置文件都改变了
ports.conf中是apache监听的端口
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf
Listen 80
<IfModule ssl_module>
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>
默认apache的虚拟主机是/etc/apache2/sites-available/000-default.conf
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
类似nginx的config文件，设置域名和端口等等相关代理设置
在apache2.conf中的是apache的全局设置，比如是否支持SSL，映射目录是什么
一个奇怪的问题php里localhost和127.0.0.1竟然不一样，识别不了localhost，查了一下大概是由于php.ini中缺少了默认sock的方式，localhost是一种特殊传递数据的方式，并不会经过socket
