前面说了内存那一关是过去了，但是又出现新的问题，说找不到表,,

这个原因就是你没初始化咯，明明我的脚本里面有初始化了啊，，为什么这里有说没有初始化呢？？？

不管了，那就手动初始化一下被

[root@ip-172-31-27-132 mysqldb]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysqldb
FATAL ERROR: please install the following Perl modules before executing /usr/local/mysql/scripts/mysql_install_db:
Data::Dumper

哎哟。。。。原来是初始化出错了啊，怪不得脚本里面的初始化没有，这个不是什么问题，都提示你说少了Perl模块了，yum install就是了

yum install autoconf
#度娘说少了这个，我也不知道为啥

重新初始化一下

[root@ip-172-31-27-132 mysqldb]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysqldb
Installing MySQL system tables...2016-09-13 02:17:50 0 [Note] /usr/local/mysql/bin/mysqld (mysqld 5.6.31-log) starting as process 15652 ...
OK

Filling help tables...2016-09-13 02:17:52 0 [Note] /usr/local/mysql/bin/mysqld (mysqld 5.6.31-log) starting as process 15676 ...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  /usr/local/mysql/bin/mysqladmin -u root password 'new-password'
  /usr/local/mysql/bin/mysqladmin -u root -h 172.31.27.132 password 'new-password'

Alternatively you can run:

  /usr/local/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

  cd . ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

Support MySQL by buying support/licenses at http://shop.mysql.com

New default config file was created as /usr/local/mysql/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

OK，初始化是Ok了，那么在重启mysqld服务

[root@ip-172-31-27-132 mysqldb]# service mysqld start
Starting MySQL... SUCCESS! 

好啦，Mysql排错就到这里了额
