linux 系统同时安装 php7.4 和 php 8.2（php多版本共存）
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-8.2.21.tar.gz tar -zxvf php-8.2.21.tar.gz cd php-8.2.21 ./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 --with-freetype --enable-gd --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
又报错：

在 centos 系统上关于 libzip 报错如下：
Requested 'libzip >= 0.11' but version of libzip is 0.10.1 ......
依次执行如下命令：
wget https://libzip.org/download/libzip-0.11.tar.gz
tar -xzvf libzip-0.11.tar.gz
cd libzip-0.11
./configure
make && make install
继续安装依然报错，再次执行：
pkg-config --list-all|grep libzip find / -name libzip.pc #我的查询结果是 /usr/loacl/libzip/lib/pkgconfig/libzip.pc #创建软链接 ln -sf /usr/loacl/libzip/lib/pkgconfig/libzip.pc /usr/lib64/pkgconfig/ pkg-config --list-all|grep libzip
ok，继续安装。
在公司的测试机（centos系统）上安装的时候报了错误：
configure: error: iconv does not support errno
依次执行：
wget https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.17.tar.gz tar -xzvf libiconv-1.17.tar.gz cd libiconv-1.17 ./configure --prefix=/usr/local/libiconv make && make install
注意：iconv 安装完毕后如果仍提示错误，则 configure 里的 --with-iconv 需要改为：
--with-iconv=/usr/local/bin/
至此，所有的错误均解决，继续安装 php，直到出现：

更改 php-fpm 的配置文件
sudo vim /usr/local/php8.2.14/etc/php-fpm.d/www.conf
更改如下内容：

php 8 环境重要配置文件：
php cli 命令文件：
/usr/local/php8.2.14/bin/php
phpize 文件：
/usr/local/php8.2.14/bin/phpize
php-config 文件：
/usr/local/php8.2.14/bin/php-config
php-fpm 文件位置：
/usr/local/php8.2.14/sbin/php-fpm
启动 php 8.2 可以运行命令：
nohup /usr/local/php8.2.14/sbin/php-fpm -c /usr/local/php8.2.14/lib/php.ini &
注意，实际启动过程中可能会报如下错误：
ERROR: unable to bind listening socket for address '/run/php/php-fpm8.2.sock': No such file or directory (2)
原因是 /run/php 目录不存在，直接运行：
mkdir /run/php
新建该目录即可，另外最好运行一下：
chmod a+rw /run/php/php-fpm8.2.sock
确保 nginx 和 fpm 交互的时候没有权限的报错。
php 扩展目录：
/usr/local/php8.2.14/lib/php/extensions/no-debug-non-zts-20220829
php-fpm 配置文件位置：
/usr/local/php8.2.14/etc/php-fpm.conf
/usr/local/php8.2.14/etc/php-fpm.d/www.conf
php-fpm pid 文件位置：
run/php-fpm.pid
php.ini 文件位置（如果不存在则手动创建）：
/usr/local/php8.2.14/lib/php.ini
给 php 8 环境安装 mongodb 扩展：
1. 去官网下载 mongodb 扩展，地址：
https://pecl.php.net/package/mongodb
2. 下载保存到本地，解压，本次保存目录在：
/webDefault/mongodb-1.17.2
依次执行如下命令：
yhm-docker@/webDefault/mongodb-1.17.2$cd mongodb-1.17.2/ yhm-docker@/webDefault/mongodb-1.17.2/mongodb-1.17.2$sudo /usr/local/php8.2.14/bin/phpize yhm-docker@/webDefault/mongodb-1.17.2/mongodb-1.17.2$sudo ./configure --with-php-config=/usr/local/php8.2.14/bin/php-config yhm-docker@/webDefault/mongodb-1.17.2/mongodb-1.17.2$sudo make yhm-docker@/webDefault/mongodb-1.17.2/mongodb-1.17.2$sudo make install
执行完会得到如下结果：
Installing shared extensions: /usr/local/php8.2.14/lib/php/extensions/no-debug-non-zts-20220829/
执行：
yhm-docker@/webDefault/mongodb-1.17.2/mongodb-1.17.2$php -m|grep mongodb mongodb
说明安装成功。

为 php 8.2 安装 xdebug 扩展：
找到 xdebug 的下载地址：https://pecl.php.net/package/xdebug
下载并安装：
yhm-docker@/webDefault$wget https://pecl.php.net/get/xdebug-3.3.1.tgz yhm-docker@/webDefault$tar -zxvf xdebug-3.3.1.tgz yhm-docker@/webDefault/xdebug-3.3.1$cd xdebug-3.3.1 yhm-docker@/webDefault/xdebug-3.3.1$phpize yhm-docker@/webDefault/xdebug-3.3.1$./configure --with-php-config=/usr/local/php8.2.14/bin/php-config yhm-docker@/webDefault/xdebug-3.3.1$sudo make yhm-docker@/webDefault/xdebug-3.3.1$sudo make install yhm-docker@/webDefault/xdebug-3.3.1$sudo vim /usr/local/php8.2.14/lib/php.ini #增加一行 extension=xdebug.so yhm-docker@/webDefault/xdebug-3.3.1$php -m| grep xdebug xdebug
至此 xdebug 扩展成功安装。
最近由于验证码图片显示不了，提示：PHP Fatal error: Call to undefined function imagettftext() 的错误，经搜索得知freetype是GD库的一部分，你装了GD不一定就支持freetype，很多人理解错误，freetype 不是一个独立的扩展，是附着在GD库上的。
freetype库相关知识补充
freetype库是一个完全免费开源的、高质量的且可移植的字体引擎，它提供统一的接口来访问多种字体格式文件，包括TrueType、OpenType、Type1、CID、CFF、Windows FON/FNT、X11 PCF等。
下面安装上 freetype ，步骤如下：
因为 php 8.2 是 2022年12月份推出来的，为了兼容考虑，本次不选择最新版本，下一个 2022 年的版本就行：
