# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

# Low memory optimizations
skip-bdb
skip-innodb
skip-networking
server-id = 1
key_buffer = 256K
max_allowed_packet=1M
thread_stack = 64K
table_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K
query_cache_limit=256K
query_cache_size = 2M

[mysqld_safe]
