php 7.4 已经存在了，nginx 也已经安装了，现在新安装 php 8.2，找到 php 源码包的下载地址：
https://www.php.net/downloads.php
选择 8.2 版本的最新地址：
wget https://www.php.net/distributions/php-8.2.14.tar.gz tar -zxvf php-8.2.14.tar.gz cd php-8.2.14 ./configure --prefix=/usr/local/php8.2.14 --sysconfdir=/usr/local/php8.2.14/etc/ --enable-opcache --enable-session --enable-fpm --with-mysqli --with-pdo-mysql=mysqlnd --with-pdo-sqlite --with-sqlite3 --with-gettext --enable-mbregex --enable-mbstring --enable-xml --with-iconv --with-mhash --with-openssl --enable-bcmath --enable-gd --enable-soap --enable-pcntl --enable-shmop --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-sockets --with-curl --with-zlib --with-bz2 --with-readline --with-webp --with-jpeg --with-imap-ssl --enable-exif --with-ffi --with-zip --with-pcre-jit
报错：
checking for libxml-2.0 >= 2.9.0... no
configure: error: Package requirements (libxml-2.0 >= 2.9.0) were not met:
No package 'libxml-2.0' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LIBXML_CFLAGS
and LIBXML_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
先查找看本地是否真的没有：
sudo find / -name libxml-2.0*
果真没找到，那就自己安装吧：
sudo apt install libxml2 sudo apt install libxml2-dev
又报错：

bzip2 已经是最新版 (1.0.8-2)。
升级了 0 个软件包，新安装了 0 个软件包， 要卸载 0 个软件包，有 0 个软件包未被升级。
我已经安装了bzip2，应该是需要安装bzip2-dev，可是运行命令sudo apt-get install bzip2-dev 结果是：E: 无法定位软件包 bzip2-dev
最后在Ubuntu bzip2 package 发现该库在Ubuntu的真正名字是libbz2-dev，所以执行如下命令配置通过：
sudo apt-get install libbz2-dev
