MySQL is used as database but does not support 4-byte characters

Pesan lengkap problemnya adalah, MySQL is used as database but does not support 4-byte characters. To be able to handle 4-byte characters (like emojis) without issues in filenames or comments for example it is recommended to enable the 4-byte support in MySQL. For further details read the documentation page about this.
Cara penyelesaiannya,
  1. 1.
    Login ke mysql (jgn menggunakan root).
  2. 2.
    Ketik show variables like 'innodb_file_format'; lalu cek kolom Value apakah = Barracuda. Jika benar, lanjutkan ke langkah nomor 5.
  3. 3.
    Apabila Value ternyata justru = Antelope, edit konfigurasi file /etc/mysql/conf.d/mysql.cnf, tambahkan kode dibawah ini.
    1
    [mysqld]
    2
    innodb_large_prefix=true
    3
    innodb_file_format=barracuda
    4
    innodb_file_per_table=1
    Copied!
  4. 4.
    Login ke mysql dan cek lagi apakah sudah berubah.
  5. 5.
    Jika sudah, jalankan perintah berikut.
    1
    ALTER DATABASE {DB_NAME} CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
    Copied!
  6. 6.
    Keluar dari mysql, jalankan perintah dibawah ini secara berurutan dari dalam path tempat Nextcloud.
    1
    sudo -u {USERNAME} /opt/rh/{PVP_VERSION}/root/bin/php occ config:system:set mysql.utf8mb4 --type boolean --value="true"
    2
    sudo -u {USERNAME} /opt/rh/{PVP_VERSION}/root/bin/php occ maintenance:repair

The “X-Content-Type-Options” HTTP header is not set to “nosniff”

Pesan lengkap problemnya adalah, The "X-Content-Type-Options" HTTP header is not set to "nosniff". This is a potential security or privacy risk, as it is recommended to adjust this setting accordingly.
Cara penyelesaiannya,
  1. 1.
    Dari terminal, jalankan perintah berikut.
    1
    curl -vvv https://URL_NEXTCLOUD
    Copied!
  2. 2.
    Pastikan entri X-Content-Type-Options: nosniff ada disitu.
  3. 3.
    Jika ternyata entri tersebut muncul beberapa kali, periksa file /etc/httpd/conf/httpd.conf. Kemungkinan entri ini pernah ada sebagai bagian setting-an dari versi yang lama. Hapus jika ada disitu.

The “X-Robots-Tag” HTTP header is not set to “none”

Pesan lengkap problemnya adalah, The "X-Robots-Tag" HTTP header is not set to "none". This is a potential security or privacy risk, as it is recommended to adjust this setting accordingly.

SQLite is currently being used as the backend database

Pesan lengkap problemnya adalah, SQLite is currently being used as the backend database. For larger installations we recommend that you switch to a different database backend. This is particularly recommended when using the desktop client for file synchronisation. To migrate to another database use the command line tool: 'occ db:convert-type', or see the documentation ↗.
Cara penyelesaiannya,
  1. 1.
    Buat db mysql baru.
  2. 2.
    Jalankan perintah berikut pada folder Nextcloud diinstal.
    1
    sudo -u {USERNAME} /opt/rh/{PVP_VERSION}/root/bin/php occ db:convert-type --all-apps mysql {DB_USERNAME} localhost {DB_NAME}
    Copied!
  3. 3.
    Masukkan pass db jika diminta.

Some columns in the database are missing a conversion to big int.

Pesan lengkap problemnya adalah, Some columns in the database are missing a conversion to big int. Due to the fact that changing column types on big tables could take some time they were not changed automatically. By running 'occ db:convert-filecache-bigint' those pending changes could be applied manually. This operation needs to be made while the instance is offline. For further details read the documentation page about this.
Cara penyelesaiannya,
Jalankan perintah berikut pada folder Nextcloud diinstal.
1
sudo -u {USERNAME} /opt/rh/{PVP_VERSION}/root/bin/php occ db:convert-filecache-bigint
Copied!

The PHP OPcache is not properly configured.

Pesan lengkap problemnya adalah, The PHP OPcache is not properly configured. For better performance we recommend to use following settings in the php.ini:
Cara penyelesaiannya,
  1. 1.
    Edit file /etc/opt/rh/{PHP_VERSION}/php.d/10-opcache.ini sesuaikan dengan konfigurasi yang disarankan pada halaman admin Nextcloud.
  2. 2.
    Jangan lupa aktifkan opcache.enable_cli=1 juga.
  3. 3.
    Simpan, dan restart dengan systemctl restart httpd.

The database is missing some indexes.

Pesan lengkap problemnya adalah, The database is missing some indexes. Due to the fact that adding indexes on big tables could take some time they were not added automatically. By running "occ db:add-missing-indices" those missing indexes could be added manually while the instance keeps running. Once the indexes are added queries to those tables are usually much faster.
Cara penyelesaiannya,
Jalankan perintah berikut pada folder Nextcloud diinstal.
1
sudo -u {USERNAME} /opt/rh/{PVP_VERSION}/root/bin/php occ db:add-missing-indices
Copied!

The database is missing some optional columns.

Pesan lengkap problemnya adalah, The database is missing some optional columns. Due to the fact that adding columns on big tables could take some time they were not added automatically when they can be optional. By running "occ db:add-missing-columns" those missing columns could be added manually while the instance keeps running. Once the columns are added some features might improve responsiveness or usability.
Cara penyelesaiannya,
Jalankan perintah berikut pada folder instalasi Nextcloud.
1
sudo -u {USERNAME} /opt/rh/{PVP_VERSION}/root/bin/php occ db:add-missing-columns
Copied!
Pesan lengkap problemnya adalah, This instance is missing some recommended PHP modules. For improved performance and better compatibility it is highly recommended to install them.
Cara penyelesaiannya,
  1. 1.
    Install modul PHP yang diminta. Contoh,
    1
    sudo yum install -y php7.0-gmp
    Copied!
    ​
  2. 2.
    Cari tahu lokasi file php.ini dalam server dengan perintah,
    1
    php --ini
    Copied!
  3. 3.
    Kemudian tambahkan pada file php.ini baris dibawah, pada bagian Dynamic Extension.
    1
    extension=php_gmp.so
    Copied!
  4. 4.
    Langkah terakhir, restart httpd dengan perintah berikut.
    1
    systemctl restart httpd
    Copied!
