Ubuntu 18 安装 Apache2，配置php 安装 wordpress

如何在Ubuntu 18.04上用Apache安装WordPress

---

安装 apache2

sudo apt update
sudo apt install apache2
// check
sudo systemctl status apache2

---

申请 SSL

sudo apt update
sudo apt install certbot

生成强Dh（Diffie-Hellman）组

Diffie-Hellman密钥交换（DH）是一种在不安全的通信信道上安全地交换加密密钥的方法。我们将生成一组新的2048位DH参数以增强安全性：

sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

获得让我们加密的SSL证书

要获取域的SSL证书，我们将使用Webroot插件，该插件的工作原理是在${webroot-path}/.well-known/acme-challenge目录中创建一个用于验证请求的域的临时文件。 Let’s Encrypt服务器向临时文件发出HTTP请求，以验证请求的域是否解析为certbot运行的服务器。

为简化起见，我们将针对.well-known/acme-challenge的所有HTTP请求映射到单个目录/var/lib/letsencrypt。

sudo mkdir -p /var/lib/letsencrypt/.well-known
sudo chgrp www-data /var/lib/letsencrypt
sudo chmod g+s /var/lib/letsencrypt

sudo vim /etc/apache2/conf-available/letsencrypt.conf

letsencrypt.conf 文件内容

Alias /.well-known/acme-challenge/ "/var/lib/letsencrypt/.well-known/acme-challenge/"
<Directory "/var/lib/letsencrypt/">
    AllowOverride None
    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
    Require method GET POST OPTIONS
</Directory>

sudo vim /etc/apache2/conf-available/ssl-params.conf

ssl-params.conf 文件内容

SSLOpenSSLConfCmd DHParameters "/etc/ssl/certs/dhparam.pem"

启动相关模组

sudo a2enmod ssl
sudo a2enmod headers

启动配置文件

sudo a2enconf letsencrypt
sudo a2enconf ssl-params

启用HTTP / 2模块，这将使您的网站更快，更健壮：

sudo a2enmod http2

重启 apache2

sudo systemctl reload apache2

现在，我们可以运行带有Webroot插件的Certbot工具，并通过输入以下内容获取SSL证书文件：

sudo certbot certonly --agree-tos --email [email protected] --webroot -w /var/lib/letsencrypt/ -d example.com -d www.example.com

自动更新以加密SSL证书

sudo vim /etc/cron.d/certbot

cerbot 内容

0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew --renew-hook "systemctl reload apache2"

sudo certbot renew --dry-run

如果没有错误，则表示更新过程成功。

安装 WordPress

sudo apt update
sudo apt upgrade

安装 php

// http
// for wordpress
sudo apt install php7.2 php7.2-mysql
// for updraftPlus Backups
sudo apt install php7.2-xml php7.2-curl
// for alidswoo，字符处理
sudo apt install php7.2-mbstring
// Wordpres, media - edit image 图像处理
sudo apt install php7.2-gd
// 其实上面的代码就够了
sudo apt install php7.2 php7.2-cli php7.2-mysql php7.2-json php7.2-opcache php7.2-mbstring php7.2-xml php7.2-gd php7.2-curl
sudo systemctl restart apache2

下载 WordPress

cd /var/www/
