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

在[MySQL(和PHP搭配之最佳组合)d]配置段添加：
max_connections = 1000
保存，重启MySQL(和PHP搭配之最佳组合)服务。
然后用命令：
MySQL(和PHP搭配之最佳组合)admin -uroot -p variables
输入root数据库账号的密码后可看到
| max_connections | 1000 |
启动mysql服务

一、导出数据库用mysqldump命令（注意mysql的安装路径，即此命令的路径）：
1、导出数据和表结构：
mysqldump -u用户名 -p 数据库名 > 数据库名.sql
#/usr/local/mysql/bin/mysqldump -uroot -p abc > abc.sql
敲回车后会提示输入密码
2、只导出表结构
mysqldump -u用户名 -p -d 数据库名 > 数据库名.sql
# ......
