Things to do after connecting server to RunCloud

MySQL

Create /etc/mysql/conf.d/z_additional.cnf with the below contents. (Note: The files are read alphabetically, so need to make to sure it is read by MySQL at the end, thus the z_ prefix.)

[mysqld]

# Disable binary log
skip-log-bin

# Default MySQL character set and collation
# See: https://coderwall.com/p/xdrjxg/proper-mysql-character-set-and-collation-setup
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
skip-character-set-client-handshake

# Useful to large multi insert query
# MySQL has a hard limit of 1GB
max_allowed_packet = 1G

# Should be total of InnoDB size + 60 or 70%
# See: https://dba.stackexchange.com/a/27341/206249
# See: https://www.liquidweb.com/kb/mysql-performance-innodb-buffers-directives/
innodb_buffer_pool_size = 16G

Run service mysql restart
