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
