问在Nexus服务器上设置经过身份验证的maven存储库

EN

To restrict anonymous access to a single repository you can create your own anonymous role with targeted permissions and assign it to the anonymous user.

1. Create a new role with the permissions you would like to grant to the anonymous user.

For example, the following allows read and browse privileges to a maven2 repository:

nx-repository-view-maven2-<repo-id>-read
nx-repository-view-maven2-<repo-id>-browse

The read privilege allows downloads, and the browse privilege allows a user to see the repository's contents in the UI.

You may also want to add the "nx-search-read" privilege to allow searching.

2. Then in Security > Users remove the default nx-anonymous role from the anonymous user, and replace it with the new role.

3. Make sure anonymous access is enabled in Security > Realms. Verify that the "local authenticating realm" and "local authorizing realm" are in the active realm list.

4. Make sure anonymous access is enabled. In Security > Anonymous make sure the check box to Allow anonymous access to the server is checked.  Also make sure the realm of the anonymous user is "local authorizing realm".
