小内存VPS Mysql优化配置 图文教程

一般mysql大家都知道的特别占内存的 有些穷站长用64m的建站 mysql根本没有办法玩，今天写个优化方案给大家。

vi?/etc/my.cnf

也可以利用winscp之类的软件

优化内容如下

[mysqld]
port = 3306
socket = /var/run/mysqld/mysqld.sock
skip-locking
key_buffer = 16K
query_cache_limit = 256K
query_cache_size = 4M
max_allowed_packet = 1M
table_cache = 8
max_connections = 16
thread_concurrency = 2
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K
skip-bdb
skip-innodb
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
no-auto-rehash
#safe-updates
[isamchk]
key_buffer = 8M
sort_buffer_size = 8M
[myisamchk]
key_buffer = 8M
sort_buffer_size = 8M
[mysqlhotcopy]
interactive-timeout

ps::随着mysql的更新不清楚会增加什么 请不要 直接替换,可以修改对应参数
