老师携程部分的这个问题

Question

PHP Warning:  PHP Startup: Unable to load dynamic library 'redis.so' (tried: /usr/lib64/php/modules/redis.so (/usr/lib64/php/modules/redis.so: undefined symbol: php_json_decode_ex), /usr/lib64/php/modules/redis.so.so (/usr/lib64/php/modules/redis.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

PHP Fatal error:  main(): must be called in the coroutine. in /var/www/html/swoole/MySql/mysql.php on line 32

我也没有用到redis。线上php7.2中确实没有redis.so这个扩展包

  下面提的那个问题解决了，就是redis扩展问题，只是协成连接一下mysql，还会报redis错误，有点懵
