DirectAdmin控制面板的Mysql优化my.cnf

找到my.cnf 文件，打开编辑。如果你不懂这些命令，你就用个带sftp功能的ssh客户端，把文件直接下载下来，修改，在上传覆盖。如果你熟悉命令，就直接  vi /etc/my.cnf  然后 按 i
然后复制如下配置文本：

[mysqld]
local-infile=0
skip-locking
query_cache_limit=1M
query_cache_size=32M
query_cache_type=1
max_connections=500
interactive_timeout=100
wait_timeout=100
connect_timeout=10
thread_cache_size=128
key_buffer=16M
join_buffer=1M
max_allowed_packet=16M
table_cache=1024
record_buffer=1M
sort_buffer_size=2M
read_buffer_size=2M
max_connect_errors=10
# Try number of CPU's*2 for thread_concurrency
thread_concurrency=2
myisam_sort_buffer_size=64M
server-id=1

[safe_mysqld]
err-log=/var/log/mysqld.log
open_files_limit=8192

[mysqldump]
quick
max_allowed_packet=16M

[mysql]
no-auto-rehash
#safe-updates

[isamchk]
key_buffer=64M
sort_buffer=64M
read_buffer=16M
write_buffer=16M

[myisamchk]
key_buffer=64M
sort_buffer=64M
read_buffer=16M
write_buffer=16M

[mysqlhotcopy]
interactive-timeout

替换my.cnf内的文本。
保存后，然后重启Mysql
/sbin/service mysqld restart
