Some help required on wordpress multi-site with Nginx
im trying to achieve the following
main wordpress installation for mysite1.com
2nd site using WP multi-site(sub-directory) mysite.com/abc
3rd site using WP multi-site (domain maping) anothersite.com
all 3 above with 1 single wordpress installation. i checked couple of tutorials but a bit confused that wordpress sub-directory and custom domain can be installed in single wordpress or not.
some detailed instruction would be appreciated.
