centos下安装mysql5.7.5的rpm包

1.首先下载mysql5.7.5,下载地址是 http://dev.mysql.com/get/Downloads/MySQL-5.7/MySQL-5.7.5-m15-0.6.m15.el6.x86_64.rpm-bundle.tar

2.用tar命令解压

  tar -xvf MySQL-5.7.5-m15-0.6.m15.el6.x86_64.rpm-bundle.tar -C ./mysql-5.7.5-m15（首先要创建mysql-5.7.5-m15这个文件夹）

3.执行rpm -ivh mysql-community-common-5.7.5-0.6.m15.el6.x86_64.rpm

 这个时候提示文件冲突，提示信息如下：

执行如下命令yum -y remove mysql-libs-5.1.71-3.el6_x86_64 将冲突的包卸载既可。

再次执行 rpm -ivh mysql-community-common-5.7.5-0.6.m15.el6.x86_64.rpm安装成功

接着执行rpm -ivh mysql-community-libs-5.7.5-0.6.m15.el6.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.5-0.6.m15.el6.x86_64.rpm

rpm -ivh mysql-community-devel-5.7.5-0.6.m15.el6.x86_64.rpm

rpm -ivh mysql-community-client-5.7.5-0.6.m15.el6.x86_64.rpm

rpm -ivh mysql-community-server-5.7.5-0.6.m15.el6.x86_64.rpm

这个时候提示错误，如下

error: Failed dependencies:
	/usr/bin/perl is needed by mysql-community-server-5.7.5-0.6.m15.el6.x86_64
	libaio.so.1()(64bit) is needed by mysql-community-server-5.7.5-0.6.m15.el6.x86_64

因为缺少依赖包：执行如下命令

yum -y install perl  libaio

然后再次执行 rpm -ivh mysql-community-server-5.7.5-0.6.m15.el6.x86_64.rpm安装成功

执行service mysqld start启动mysql数据库

4.登录后发现无法设置新密码，也不能grant。因为mysql5.6新加了一个密码验证插件，必须要设置一个复杂的密码才可以做相关的操作，但是这个插件不会对散列后的密码进行检查，示例如下

mysql> SET PASSWORD = PASSWORD('abc');
ERROR 1819 (HY000): Your password does not satisfy the current policy
requirements
Passwords specified as already hashed values are not checked because the original password value is not available:
mysql> SET PASSWORD = '*0D3CED9BEC10A777AEC23CCC353A8C08A633045E';
Query OK, 0 rows affected (0.01 sec)

所以我们只要先将密码设置成上面散列过的密码，然后再把密码验证插件卸掉，就可以进行相关的操作 

登陆mysql，命令行下直接安装/卸载插件插件
           安装：INSTALL PLUGIN validate_password SONAME 'validate_password.so';
           卸载：UNINSTALL PLUGIN validate_password ;

5. 添加一个可远程登录的帐号 root ,且设置密码123456，能访问所有库 如远程无法访问关闭防火墙或添加入站出站规则，添加端口3306

GRANT   all   privileges   on  *.*  TO   'root' @ '%'  identified  by   '123456'   WITH   GRANT   OPTION ;    

FLUSH  PRIVILEGES ;
