大体步骤：

到mysql官网，找到合适自己的安装包下载下来，也可以直接在linux命令行中用wget命令直接下载，我这里是先在家里下好的。

下载页面：http://dev.mysql.com/downloads/mysql/

找到合适自己操作系统的版本即可(注意32位还是64位的)，比如我是centos6.5，可以下red hat版的，也可以下linux generic版的。

安装包有好几种，rpm（安装版）、tar.gz（解压版）、源码版（没看到）

最终我下载的是mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz

不扯淡了，来正文：

1.创建组和用户：

groupadd mysql

useradd mysql -r -g msyql mysql

2.把下好的压缩包搞到服务器上去

把压缩包搞到这个目录： /usr/local

解压：

tar zxvf mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz

删除压缩包

rm -rf mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz

重命名为mysql

mv mysql-5.6.29-linux-glibc2.5-x86_64 mysql

进入mysql目录，并初始化msyql数据库

cd /usr/local/mysql

#初始化mysql数据库

      scripts/mysql_install_db --user=mysql

       #也可以这么初始化
       scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql --ldata=/var/lib/mysql

3.开启mysql

bin/mysqld_safe --user=mysql

4.执行安全机制

#bin/mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS

      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password

password for the root user.  If you've just installed MySQL, andyou haven't set the root password yet, the password will be blank,
so you should just press enter here.
 
Enter current password

you haven't set the root password yet, the password will be blank,

so you should just press enter here.

Enter current password for root (enter for none):<---输入现在的root密码，因为我们还没设置，直接回车OK, successfully used password, moving on...
 
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
 
Set root password

OK, successfully used password, moving on...

Password updated successfully

Password updated successfully!

Reloading privilege tables..

 ... Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created

to log into MySQL without having to have a user account created for

them.  This is intended only for testing, and to make the installationgo a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] Y <---是否删除匿名用户，删除，输入Y回车
 ... Success

 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This

ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Y <---是否删禁止root用户远程登录，当然禁止，输入Y回车
 ... Success

 ... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

Reload privilege tables now? [Y/n] Y <---刷新权限，输入Y回车
 ... Success

Cleaning up...

All done!  If you've completed all of the above steps, your MySQLinstallation should now be secure.
