1、下载：当前mysql版本到了5.6.20

   http://dev.mysql.com/downloads/mysql #选择Source Code

 2、必要软件包
            yum -y install  gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake

       3、编译安装添加用户
            groupadd mysqluseradd -r -g mysql mysql
            编译安装
            tar -zxvf mysql-5.6.20.tar.gzcd mysql-5.6.20#默认情况下是安装在/usr/local/mysql
            cmake .make && make install
            编译参数
            cmake .-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \-DMYSQL_DATADIR=/usr/local/mysql/data \-DSYSCONFDIR=/etc \-DWITH_MYISAM_STORAGE_ENGINE=1 \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_MEMORY_STORAGE_ENGINE=1 \-DWITH_READLINE=1 \-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \-DMYSQL_TCP_PORT=3306 \-DENABLED_LOCAL_INFILE=1 \-DWITH_PARTITION_STORAGE_ENGINE=1 \-DEXTRA_CHARSETS=all \-DDEFAULT_CHARSET=utf8 \-DDEFAULT_COLLATION=utf8_general_ci

       编译的参数可以参考http://dev.mysql.com/doc/refman/5.6/en/source-configuration-options.html
        改变目录所有者
            chown -R mysql.mysql /usr/local/mysql

      4、初始化数据库
            cd /usr/local/mysql/scripts./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

      5、注册为服务
           cd /usr/local/mysql/support-files#注册服务
           cp mysql.server /etc/rc.d/init.d/mysql#使用默认配置文件
           cp my-default.cnf /etc/my.cnf#让chkconfig管理mysql服务
           chkconfig --add mysql#开机启动
           chkconfig mysql on

     6、启动MySQL服务
           service mysql start

     7、改变编码，防止乱码
          SHOW VARIABLES LIKE 'character%'
      修改mysql的my.cnf文件

    [client]default-character-set=utf8[mysqld]character-set-server=utf8[mysql]default-character-set=utf8

     8、将mysql的bin加入到path中
           cd ~#我把path添加到当前用户目录的bashrc中，如果需要全局设定，请修改`/etc/profile`vi .bashrc#加入以下内容PATH=/usr/local/mysql/bin:$PATHexport PATH

     9、配置用户密码和远程访问权限
          mysql -uroot  SET PASSWORD = PASSWORD('123456');
          GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
