shell 之 mysql安装脚本
此文为mysql 服务器安装脚本。#!/bin/bash
#ver 0.2
#by zm 2011/04/23
#安装 mysql_server;
#注意！！
#参数解释
#
# CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors \
# -fno-exceptions -fno-rtti -fomit-frame-pointer -ffixed-ebp" // 如果是Inter处理器，使用pgcc提高1%性能
#
#
# --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
# --with-client-ldflags=-all-static
# --with-mysqld-ldflags=-all-static //-static13%,静态链接提高13%性能
#
# --with-readline 从“行”上面读取
#
# --with- 指定缺省字符集
#
# --with-collation=utf8_general_ci指定缺省排序方式
#
# --with-extra-charsets=complex安装所有字符，有这个就足够了
#
# --with-extra-charsets=all 指定安装扩展字符集
#
# --enable-local-infile 指定允许本地导入文件
#
# --enable-thread-safe-client 指定线程安全模式
#
# --enable-assembler 允许使用汇编模式(优化性能)
#
# --with-big-tables 指定支持超大表
#
# --without-debug去除诊断模式，如果用--with-debug=full编译，大多数查询慢20%
#
