This article will explain in detail how to use the chcon command in Linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The chcon command modifies the security context of the object (file), such as user, role, type, and security level. That is, change the security environment of each file to the specified environment.

Chcon modifies the security context of an object (file)

Add that when the chcon command uses the-- reference option, it sets the security environment of the specified file to the same as the reference file. The chcon command is located at / usr/bin/chcon.

Syntax chcon [options]... Environmental documents. Chcon [options]... [- u user] [- r role] [- l range] [- t type] file. Chcon [options]... -- reference= reference file file. Option-h,-- no-dereference: files that affect symbolic links rather than references. -- reference= reference file: uses the security environment of the specified reference file instead of specifying a value. -R,-- recursive: recursively processes all files and subdirectories. -v,-- verbose: displays diagnostic information for all files processed. -u,-- user= user: sets the target security environment for the specified user. -r,-- role= role: sets the target security environment for the specified role. -t,-- type= type: sets the target security environment of the specified type. -l,-- range= range: sets the target security environment of the specified range. The following options are used to set how to traverse the directory structure when the-R option is specified. If you specify more than one option, only the last one will take effect.

-H: if the command line argument is a symbolic link to the directory, traverse the symbolic link. -L: traverse every symbolic link to the directory that you encounter. -P: does not traverse any symbolic links (default). -- help: display this help and exit. -- version: displays version information and exits. Example if you want to share this ftp with anonymous users, you need to enable the following:

Chcon-R-t public_content_t / var/ftp if you want the FTP directory you set up to upload files, SELINUX needs to be set up:

Chcon-t public_content_rw_t / var/ftp/incoming allows the user HHTP to access their home directory, which is limited to the user's home directory home page:

Setsebool-P httpd_enable_homedirs 1 chcon-R-t httpd_sys_content_t ~ user/public_html if you want to share the samba directory with other users, you need to set:

When chcon-t samba_share_t / directory shares the rsync directory:

Chcon-t public_content_t / directories on "how to use chcon commands in Linux" this article is shared here, I hope the above content can be of some help to you, so that you can learn more knowledge, if you think the article is good, please share it for more people to see.
