mysql 5.1 configure 编译参数详解
-static 13%
--with-client-ldflags=-all-static
--with-mysqld-ldflags=-all-static
静态链接提高13%性能
Unix Socket 7.5%
--with-unix-socket path=/usr/local/mysql/tmp/mysql.sock
使用unix套接字链接提高7.5%性能，所以在windows下mysql性能肯定不如unix下面
--enable-assembler
The --enable-assembler options of configure allows for
compiling in x86 (and sparc) versions of common
string
operations, which should result in more
performance.
汇编x86的普通操作符，可以提高性能
--with-extra-charsets
=complex字符支持
--enable-thread-safe-client
#Compile the client with
threads. 也就是让客户端支持线程的意思
--with-big-tables
There is a limit of 232
(~4.295E+09) rows in a MyISAM
table. If you build MySQL
with the --with-big-tables
option, the
row limitation is increased to (232
)2
(1.844E+19) rows
--with-ssl
--with-embedded-server
#编译成embedded MySQL library (libmysqld.a
),
--enable-local-infile
#让mysql支持从本地文件 导入数据库
load data local infile '/usr/test' into table test fields terminated by ' ';
ERROR 1148 (42000): The used command is
not allowed with this
MySQL version）
--with-plugins=innobase
存储引擎
Mysql5.1开始，编译添加innodb插件就从--with-innodb 改成了 --with-plugins=innobase
--with-plugins=PLUGIN[[[,PLUGIN..]]]
Plugins to include in
mysqld. (default
is

首先要声明一点，大部分情况下，修改MySQL是需要有mysql里的root权限的，
所以一般用户无法更改密码，除非请求管理员。
方法一
使用phpmyadmin，这是最简单的了，修改mysql库的user表，
不过别忘了使用PASSWORD函数。
方法二
使用mysqladmin，这是前面声明的一个特例。
mysqladmin -u root -p password mypas ......

了解了一些最基本的操作命令后，我们再来学习如何创建一个数据库和数据库表。
1、使用SHOW语句找出在服务器上当前存在什么数据库：
mysql> SHOW DATABASES; +----------+
| Database | +----------+ | mysql |
| test | +----------+ 3 rows in set (0.00 sec)
2、创建一个数据库abccs

Starting the cluster is not very difficult after it has been configured. Each cluster node process must be started separately, and on the host where it resides. The management node should be started first, followed by the data nodes, and then finally by any SQL nodes:
On the management host, issu ......
