Unable to create directory wp-content/uploads/2017/11. Is its parent directory writable by the server?

install wordpress plugin error:
Unable to create directory wp-content/uploads/2017/11. Is its parent directory writable by the server?

it's not a problem! very simple.

step1: enter the wp-content directory under WordPress, build a new uploads folder(I am the Linux system)

[root@VM_230_32_centos wordpress]# cd wp-content/

[root@VM_230_32_centos wp-content]# mkdir uploads

step2: you should assign a writable permissions to the uploads directory, run the following commands.

[root@VM_230_32_centos wp-content]# chmod -R a+w uploads

ok!
