[PHP知识库]Swoole 4.6.7 在WSL1下的Socket问题及修正

环境:

• Win10 + WSL1 (Ubuntu 18.04.3 LTS)
• php7.3 / 7.4 / 8
• swoole 4.6.7
• easyswoole 3.4.6

问题: 启动easyswoole时触发socket错误

排查：

1. 不同php 版本测试，仍触发相同错误
2. 不同swoole 版本测试，仍触发相同错误
3. 不同easyswoole版本测试，仍触发相同错误
4. 放入真Ubuntu测试，没出现问题，于是怀疑WSL导致

解决方法:

1. 更新windows
2. 升级到WSL2
3. easyswoole配置中的 'TEMP_DIR' => '/tmp'
