Configuring MySQL for Low Memory VPS

I’ve found the following configuration helps when you’re trying to squeeze out as much memory from a VPS as possible.


port = 3306
socket = /var/lib/mysql/mysql.sock
key_buffer = 16K
max_allowed_packet = 1M
table_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K

# For low memory, Berkeley DB should not be used so keep skip-bdb uncommented unless required

# For low memory, InnoDB should not be used so keep skip-innodb uncommented unless required

# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = /var/lib/mysql/
#innodb_data_file_path = ibdata1:10M:autoextend
#innodb_log_group_home_dir = /var/lib/mysql/
#innodb_log_arch_dir = /var/lib/mysql/
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
#innodb_buffer_pool_size = 16M
#innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
#innodb_log_file_size = 5M
#innodb_log_buffer_size = 8M
#innodb_flush_log_at_trx_commit = 1
#innodb_lock_wait_timeout = 50

max_allowed_packet = 16M

# Remove the next comment character if you are not familiar with SQL

key_buffer = 8M
sort_buffer_size = 8M

key_buffer = 8M
sort_buffer_size = 8M
