低内存服务器MySQL优化

Linode提供了一个用于低内存服务 器的MySQL优化建议，可以用来参考。

 

 配置文件: /etc/my.cnf

 

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

# Default to using old password format for compatibility with mysql 3.x

# 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]

log-error=/var/log/mysqld.log

pid-file=/var/run/my
