Изменить каталог данных сервера mongodb

Question

Изменить каталог данных сервера mongodb

Запуск Fedora-27, я пытаюсь изменить каталог по умолчанию mongodb в подкаталог моего домашнего каталога.

sudo dnf install mongodb-server

Версия

[idf@localhost mongodb]$ mongod --version
db version v3.4.6
git version: c55eb86ef46ee7aede3b1e2a5d184a7df4bfb5b5
OpenSSL version: OpenSSL 1.1.0g-fips  2 Nov 2017
allocator: tcmalloc
modules: none
build environment:
    distarch: x86_64
    target_arch: x86_64
[idf@localhost mongodb]$

Я добавил себя в группу mongodb

[idf@localhost mongodb]$ sudo usermod -g mongodb idf
usermod: no changes
[idf@localhost mongodb]$

Не меняя ничего, я меняю файл /etc/mongodb.conf чтобы dbPath указывает на каталог, который я создал:

[idf@localhost mongodb]$ more /etc/mongod.conf

[idf@localhost mongodb]$ sudo systemctl start mongod

Пока я могу начать mongodb если mongodb.conf файл dbpath точки входа в /var/libесли я изменюсь dbpath в каталог, который я продублировал в моем домашнем каталоге, я получаю сообщение об ошибке:

[idf@localhost mongodb]$ sudo systemctl start mongod
[sudo] password for idf: 
Job for mongod.service failed because the control process exited with error code.
See "systemctl  status mongod.service" and "journalctl  -xe" for details.

status дает больше информации, но я не знаю, что это значит:

Файл журнала дает интересную информацию [строка Unable to determine status of lock file in the data directory], но я не знаю, как ее разрешить, так как я продублировал permissions а также ownership от /var/lib/mongod каталог:

Если я бегу mongod "от руки" [не использует service...], это работает в моем каталоге данных. Bizarre...

[idf@localhost mongodb]$ sudo mongod --dbpath /home/idf/mongodb/

Можете ли вы проверить, как SELinux настроен в вашей системе?

sestatus
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux
SELinux root directory:         /etc/selinux
Loaded policy name:             targeted
Current mode:                   permissive
Mode from config file:          permissive
Policy MLS status:              enabled
Policy deny_unknown status:     allowed
Max kernel policy version:      28

Если SELinux находится в принудительном режиме, включите доступ к соответствующему порту:

sudo semanage port -a -t mongod_port_t -p tcp 27017

Попробуйте установить его в разрешающий:

setenforce permissive

это будет действовать до следующей перезагрузки, чтобы сделать его постоянным, отредактируйте /etc/selinux/config
