下载最新的mysql 发行版5.5.2 ，目前还是测试阶段。

我的具体步骤:

shell> groupadd mysql
shell> useradd -g mysql mysql

shell> $ ./configure --prefix=/usr/local/mysql --bindir=/usr/local/bin --sbindir=/usr/local/sbin --disable-dependency-tracking --enable-profiling --with-charset=utf8 --with-extra-charsets=all --with-server-suffix --with-unix-socket-path=/var/tmp/mysql.sock --with-mysqld-user=mysql --with-zlib-dir=bundled --with-big-tables --with-embedded-server --with-embedded-privilege-control

shell> make
这里报了错，提示缺少g++ ,囧rz
于是 yum install gcc-c++, make clean,再次make 通过.

shell> make install
再次报错，提示变量已声明。
原来是缺少g++ 检查依赖的后果.
于是重复上面两步.通过

shell> cp support-files/my-medium.cnf /etc/my.cnf (内容酌情编辑)
shell> cd /usr/local/mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> mysql_install_db
shell> chown -R root .
shell> chown -R mysql var
shell> mysqld_safe --user=mysql &
服务启动成功.
