-----------1 卸载系统自带的msyql包
rpm -qa|grep mysql
rpm -e --nodeps mysql-server-5.1.71-1.el6.x86_64 --强制卸载mysql安装程序
rpm -e mysql-server-5.1.71-1.el6.x86_64 -- 有依赖关系，无法卸载
---------- 2 安装cmake 编译软件 mysql5.6开始不使用configure 方式
yum -y install cmake make
---------- 3 安装mysql 的依赖包，其他linux 需要一个个软件下载 编译安装
yum install gcc gcc-c++ autoconf bison automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* -y
---------- 4 创建mysql 目录 存放日志和数据文件等 并更改目录拥有者
mkdir /mysql
mkdir /mysql/data
mkdir /mysql/logs
mkdir /mysql/data/socket
chown mysql.mysql -R /mysql
---------- 5 创建mysql用户并不允许登录系统
groupadd mysql
useradd mysql -g mysql -s /sbin/nologin
---------- 6 解压（需要切换到mysql-5.6.19.tar.gz的存放目录）
tar -zxvf mysql-5.6.19.tar.gz
---------- 7 进入mysql解压目录
cd mysql-5.6.19
---------- 8 编译

--------- 9 make 安装
make
--------- 10 make 安装
make install
--------- 11 负载启动命令道系统启动目录
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
--------- 12 设置为开机启动 chkconfig --list|grep mysqld 检测是否已经设置为开机启动
chkconfig mysqld on
--------- 13 复制mysql命令道系统环境变量
cp /usr/local/mysql/bin/mysql /usr/bin/mysql
cp /usr/local/mysql/bin/mysql /usr/local/bin/mysql
--------- 14 初始化mysql系统数据库 (需要回到/根目录执行)
./usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/data
--------- 15 mysql 修改密码 -------------------------
> use mysql;
> UPDATE user SET password=PASSWORD('txt!@#123txt');
> FLUSH PRIVILEGES;
--------- 16 删除不必要的用于
> delete from user where host <> 'localhost';
> update user set host='%';
> FLUSH PRIVILEGES;
--------------------------------------------附---------------------------------------------
grant all privileges on *.* to root@'%' identified by "txt!@#123txt";
