PHP版本

[root@iZm5e86n6s2oqyjbprukreZ swoole-src-4.5.2]# php -v
PHP 7.2.24 (cli) (built: May 11 2020 12:09:51) ( NTS )

php的安装路径： /usr/local/php

php.ini配置文件：/usr/local/php/etc/php.ini

phpize文件位置：/usr/local/php/bin/phpize

使用本教程之前，先确认文件路径是否一致(不一样的不要傻瓜式的套用，要学会比葫芦画瓢)

1.为了方便管理扩展文件，我把需要下载的源码包放在了/usr/local/src目录下（可根据自身需求）

cd /usr/local/src

2.下载swoole源码

wget  https://github.com/swoole/swoole-src/archive/v4.5.2.tar.gz

3.解压源码包

tar zxvf v4.5.2.tar.gz

4.进入解压目录

cd swoole-src-4.5.2

5.运行phpize

/usr/local/php/bin/phpize

6.配置信息

./configure --with-php-config=/usr/local/php/bin/php-config

7.安装

make && make install

8.修改php.ini文件

vi /usr/local/php/etc/php.ini

按shift+i 进入编辑模式

查找extension_dir = "ext"，修改值为/usr/local/php/lib/php/extensions/no-debug-non-zts-20170718(此值并不是一成不变的)

然后添加一行extension = swoole.so

按esc退出编辑模式，按ctrl+: ，再按wq!保存退出

9.重启php-fpm

service php-fpm restart

10.重启时可能出现的报错(没报错直接跳过)

Gracefully shutting down php-fpm . done
Starting php-fpm [22-Jun-2020 11:47:09] NOTICE: PHP message: PHP Warning:  PHP Startup: Unable to load dynamic library 'swoole.so' (tried: /usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so (/usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so: cannot open shared object file: No such file or directory), /usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so.so (/usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

<b>Warning</b>:  PHP Startup: Unable to load dynamic library 'swoole.so' (tried: /usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so (/usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so: cannot open shared object file: No such file or directory), /usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so.so (/usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/swoole.so.so: cannot open shared object file: No such file or directory)) in <b>Unknown</b> on line

这个是因为/usr/local/php/lib/php/extensions/no-debug-non-zts-20170718下没有swoole.os导致

重新编译一下，依次执行

cd /usr/local/src/swoole-src-4.5.2
phpize && ./configure --with-php-config=/usr/local/php/bin/php-config && make && sudo make install

运行结果最后两行如下

Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/
Installing header files:          /usr/local/php/include/php/

php -m

结果如下

运行phpinfo()也可查看，结果如下

如果能看到swoole，就说明安装成功了
