编译安装swoole 启用openssl支持，Mac，php7.4.6.已安装swoole的重新编译安装一次也可以。生成swoole.so之后覆盖之前的swoole.so就行。

一、首先要安装openssl，没有的可以百度一下安装openssl，执行如下命令如果有输出路径即可

Yanzhongxin:consul admin$ which openssl
/usr/bin/openssl

二、编译安装swoole

最初我的swoole版本是4.6.3，反复重新编译安装都失败了。

于是我重新下载了swoole4.6.4：

http://pecl.php.net/package/swoole

解压后进入目录

Yanzhongxin:swoole-4.6.4 admin$ /Applications/MxSrvs/bin/php/bin/phpize
Configuring for:
PHP Api Version:         20190902
Zend Module Api No:      20190902
Zend Extension Api No:   320190902
Yanzhongxin:swoole-4.6.4 admin$ ./configure --enable-openssl --with-openssl-dir=/usr/local/opt/openssl --enable-http2 --with-php-config=/Applications/MxSrvs/bin/php/bin/php-config
……
Yanzhongxin:swoole-4.6.4 admin$ make

……
Yanzhongxin:swoole-4.6.4 admin$ make install 
Installing shared extensions: /Applications/MxSrvs/bin/php/lib/php/extensions/no-debug-non-zts-20190902/ Installing header files: /Applications/MxSrvs/bin/php/include/php/

上面注意一下：

1.openssl路径是/usr/bin/openssl

执行命令发现并找不到

Yanzhongxin:consul admin$ cd /usr/bin/openssl
bash: cd: /usr/bin/openssl: Not a directory
Yanzhongxin:consul admin$ cd /usr/local/opt/openssl
Yanzhongxin:openssl admin$ ls
AUTHORS                 INSTALL_RECEIPT.json    NEWS                    bin                     lib
CHANGES                 LICENSE                 README                  include                 share

./configure –enable-openssl –with-openssl-dir=

/usr/local/opt/openssl

–enable-http2 –with-php-config=/Applications/MxSrvs/bin/php/bin/php-config

所以这里注意openssl-dir的路径地址

2.编译后swoole.so的存放位置为：

Installing shared extensions:

/Applications/MxSrvs/bin/php/lib/php/extensions/no-debug-non-zts-20190902

3.请确定php.ini配置中加了extension=swoole.so的配置的

可以参考如下配置

extension=/Applications/MxSrvs/bin/php/lib/php/extensions/no-debug-non-zts-20190902/swoole.so
swoole.use_shortname = 'Off'

也可以将swoole.so 复制到php的ext/目录下

php.ini配置即为extension=swoole.so

三、查看安装是否成功开启了openssl

Yanzhongxin:swoole-4.6.4 admin$ php --ri swoole
