Security-Enhanced Linux secures the couchdb processes via flexible mandatory access control.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the couchdb_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the couchdb_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux couchdb policy is very flexible allowing users to setup their couchdb processes in as secure a method as possible.
The following file types are defined for couchdb:
couchdb_etc_t
- Set files with the couchdb_etc_t type, if you want to store couchdb files in the /etc directories.
couchdb_exec_t
- Set files with the couchdb_exec_t type, if you want to transition an executable to the couchdb_t domain.
couchdb_log_t
- Set files with the couchdb_log_t type, if you want to treat the data as couchdb log data, usually stored under the /var/log directory.
couchdb_tmp_t
- Set files with the couchdb_tmp_t type, if you want to store couchdb temporary files in the /tmp directories.
couchdb_unit_file_t
- Set files with the couchdb_unit_file_t type, if you want to treat the files as couchdb unit content.
couchdb_var_lib_t
- Set files with the couchdb_var_lib_t type, if you want to store the couchdb files under the /var/lib directory.
couchdb_var_run_t
- Set files with the couchdb_var_run_t type, if you want to store the couchdb files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux couchdb policy is very flexible allowing users to setup their couchdb processes in as secure a method as possible.
The following port types are defined for couchdb:
Default Defined Ports: tcp 5984 udp 5984
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux couchdb policy is very flexible allowing users to setup their couchdb processes in as secure a method as possible.
The following process types are defined for couchdb:
couchdb_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
The SELinux user type couchdb_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
couchdb_log_t
/var/log/couchdb(/.*)?
couchdb_tmp_t
couchdb_var_lib_t
/var/lib/couchdb(/.*)?
couchdb_var_run_t
/var/run/couchdb(/.*)?
