1.环境已源码安装php5.6 和php7.3
目录
[root@iZ2zedsf2i1n3fvo7zc64kZ no-debug-non-zts-20190902]# cd /usr/local/php
[root@iZ2zedsf2i1n3fvo7zc64kZ php]# ll
total 8
drwxr-xr-x 9 root root 4096 Apr 24 10:43 56
drwxr-xr-x 9 root root 4096 Apr 24 10:56 74
版本看到的是最新版本：
[root@iZ2zedsf2i1n3fvo7zc64kZ no-debug-non-zts-20190902]# php -v
PHP 7.4.33 (cli) (built: Apr 24 2023 10:56:01) ( NTS )
Copyright (c) The PHP Group

2.下载swoole 4.8.13 php8.0以下的最新版本
https://gitee.com/swoole/swoole/repository/archive/v4.8.13
3.进入目录安装
[root@iZ2zedsf2i1n3fvo7zc64kZ ~]# ll
-rw-r--r-- 1 root root 2875113 May 24 09:45 swoole-v4.8.13.zip
[root@iZ2zedsf2i1n3fvo7zc64kZ ~]# unzip swoole-v4.8.13.zip
[root@iZ2zedsf2i1n3fvo7zc64kZ ~]# cd swoole-v4.8.13/
由于php多版本，考虑swoole扩展安装到哪个版本下
[root@iZ2zedsf2i1n3fvo7zc64kZ swoole-v4.8.13]# whereis phpize
phpize: /usr/local/php/74/bin/phpize
[root@iZ2zedsf2i1n3fvo7zc64kZ swoole-v4.8.13]# /usr/local/php/74/bin/phpize
[root@iZ2zedsf2i1n3fvo7zc64kZ swoole-v4.8.13]# ./configure --with-php-config=/usr/local/php/74/bin/php-config
[root@iZ2zedsf2i1n3fvo7zc64kZ swoole-v4.8.13]# make && make install
安装成功如下图：
creating swoole.la
(cd .libs && rm -f swoole.la && ln -s ../swoole.la swoole.la)
/bin/sh /root/swoole-v4.8.13/libtool --mode=install cp ./swoole.la /root/swoole-v4.8.13/modules
cp ./.libs/swoole.so /root/swoole-v4.8.13/modules/swoole.so
cp ./.libs/swoole.lai /root/swoole-v4.8.13/modules/swoole.la
PATH="$PATH:/sbin" ldconfig -n /root/swoole-v4.8.13/modules
----------------------------------------------------------------------
Libraries have been installed in:
/root/swoole-v4.8.13/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.

4.配置使用扩展
[root@iZ2zedsf2i1n3fvo7zc64kZ no-debug-non-zts-20190902]# php --ini
Configuration File (php.ini) Path: /usr/local/php/74/etc
Loaded Configuration File: /usr/local/php/74/etc/php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed: (none)
vi /usr/local/php/74/etc/php.ini
最后，编译安装成功后，修改 php.ini 加入
extension=swoole.so通过 php -m 来查看是否成功加载了 swoole.so，如果没有可能是 php.ini 的路径不对。
可以使用 php --ini 来定位到 php.ini 的绝对路径，Loaded Configuration File 一项显示的是加载的 php.ini 文件，如果值为 none 证明根本没加载任何 php.ini 文件，需要自己创建。
