"No such file or directory" error

when we want to use redis unixsocket it is possible that given path for socket does not exist.
in this situation if we start redis-server with given config, error occurred with this message:
Opening Unix socket: bind: No such file or directory

To reproduce

Steps to reproduce the behavior and/or a minimal code sample.
you can delete unixsocket path and start to run redis server.
for example change unixsocket path to /var/run/redis/redis.sock and delte /var/run/redis path.
now in redis directory execute this command : src/redis-socket redis.conf

**Expected behavior **
redis most check unixsocket path and check if it does not exist create related path recursively.
