安裝MySQL 安裝前確認以下包已經裝好gcc gcc-c++ ncurses-devel

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql

tar zxvf mysql-5.4.0-beta.tar.gz

cd mysql-5.4.0-beta

CFLAGS="-O6 -mpentiumpro -fomit-frame-pointer" CXX=gcc CXXFLAGS="-O6 -mpentiumpro -fomit-frame-pointer -felide-constructors -fno-exceptions -fno-rtti"

./configure –prefix=/usr/local/mysql –localstatedir=/usr/local/mysql/var/ –with-server-suffix=-enterprise-gpl –without-debug –with-big-tables –with-extra-charsets=latin1,gb2312,big5,utf8,GBK –with-extra-charsets=all –with-pthread –enable-static –enable-thread-safe-client –with-client-ldflags=-all-static –with-mysqld-ldflags=-all-static –enable-assembler –without-innodb –without-ndb-debug –without-isam –with-federated-storage-engine

make && make install

cp support-files/my-medium.cnf /usr/local/mysql/my.cnf

/usr/local/mysql/bin/mysql_install_db –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –user=mysql

my.cnf文件記得註銷–skip-federated引擎功能再啟動mysql

./mysqld_safe –defaults-file=/usr/local/mysql/my.cnf –user=mysql &

mysql編譯參數說明：根據 ./configure –help 查看支持配置的參數

-pgcc和-O6編譯

CFLAGS="-O6 -mpentiumpro -fomit-frame-pointer" CXX=gcc CXXFLAGS="-O6 -mpentiumpro -fomit-frame-pointer -felide-constructors -fno-exceptions -fno-rtti"

總體性能可提高10%，當然如果服務器不是用奔騰處理器，就不必用它瞭，因為它是專為奔騰系統設計的

-static靜態編譯

–enable-static

–with-client-ldflags=-all-static

–with-mysqld-ldflags=-all-static

以靜態方式編譯客戶端和服務端，能提高13%性能

–enable-thread-safe-client

以線程方式編譯客戶端

–without-innodb

去掉innodb表支持，innodb是一種支持事務處理的表，適合企業級應用

–without-isam

去掉isam表類型支持，現在很少用瞭，isam表是一種依賴平臺的表

–without-ndb-debug

取消導航調試

–localstatedir=/usr/local/mysql/var/

日志文件目錄

–with-server-suffix=-enterprise-gpl

給MySQL加個後綴名，在用mysql登錄的時候在版本號的後面可以看到

–without-debug

去除診斷模式，如果用–with-debug=full編譯，大多數查詢慢20%

–with-big-tables

大表支持

–with-extra-charsers=gbk,gb2312,utf8

設置支持gbk,gb2312,utf8字符集

–with-pthread

強制使用pthread庫(posix線程庫)

–enable-assembler

使用一些字符函數來匯編版本

–with-federated-storage-engine

這個參數已經被廢除，代替它的是–with-plugin系列

cp support-files/my-medium.cnf /usr/local/mysql/my.cnf

mysql/support-files裡面有配置文件范本，根據實際情況選擇或者更改

/usr/local/mysql/bin/mysql_install_db –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –user=mysql –defaults-file=/usr/local/mysql/my.cnf –pid-file=/usr/local/mysql/mysql.pid

設定默認值：默認空間路徑；默認數據文件路徑；默認用戶；默認配置文件路徑；默認PID文件路徑。

——————————————————-

本腳步未加入的編譯參數：

–with-charset=utf8

設置默認字符集

–with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock

使用unix套接字鏈接提高7.5%性能，所以在windows下mysql性能肯定不如 unix

–with-tcp-port=3306

指定MySQL實例將監聽TCP 3306端口
