Ccnet is the internal RPC framework used by Seafile server and also manages the user database. A few useful options are in ccnet.conf. Ccnet component is merged into seaf-server in version 7.1, but the configuration file are still needed.

# This is outside URL for Seahub(Seafile Web). 
# The domain part (i.e., will be used in generating share links and download/upload file via web.
# Note: Outside URL means "if you use Nginx, it should be the Nginx's address"
# Note: SERVICE_URL is moved to since 9.0.0

Changing MySQL Connection Pool Size

When you configure ccnet to use MySQL, the default connection pool size is 100, which should be enough for most use cases. You can change this value by adding following options to ccnet.conf:

# Use larger connection pool

Using Encrypted Connections

Since Seafile 10.0.2, you can enable the encrypted connections to the MySQL server by adding the following configuration options:

USE_SSL = true
CA_PATH = /etc/mysql/ca.pem

When set use_ssl to true and skip_verify to false, it will check whether the MySQL server certificate is legal through the CA configured in ca_path. The ca_path is a trusted CA certificate path for signing MySQL server certificates. When skip_verify is true, there is no need to add the ca_path option. The MySQL server certificate won't be verified at this time.

Using unix_socket Authentication Plugin

Since Seafile 10.0.3 and 10.0.7 Pro, you can use unix_socket authentication plugin provided by MariaDB/MySQL. To enable it, you need to specify the UNIX_SOCKET option without user name and password.

UNIX_SOCKET = /var/run/mysqld/mysqld.sock
