[升级用到]Mysql升级脚本，每次升级均得用到，mysql create user mysql.plugin table. Please run mysql_upgrade to create it
Mysql升级脚本，每次升级均得用到：
./mysql_upgrade -p
Enter password:
Checking if update is needed.
Checking server version.
Running queries to upgrade MySQL server.
......
Upgrade process completed successfully.
Checking if update is needed.
参考：http://dev.mysql.com/doc/refman/5.7/en/upgrading-from-previous-series.html
如果不升级会出现什么情况？尽管运行了，但是用phpMyadmin后会出现如下错误：
MySQL 返回： 文档
#1146 - Table 'information_schema.CHARACTER_SETS' doesn't exist
information_schema这个库，`CHARACTER_SETS`这个表，因为升级后没有这个表了，需要运行./mysql_upgrade -p 在information_schema库里生成一系列的表。
101007 22:30:31 [ERROR] Can't open the mysql.plugin table. Please run the mysql_upgrade script to create it.
101007 22:30:31 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist
101007 22:30:31 mysqld ended
再源码下面执行，如下：
linux-Jack-nb4:~/webserver/mysql-5.1.12-beta # ./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/var
Installing all prepared tables
Fill help tables
Linux:
bin/mysql_install_db --user=mysql --datadir=/data/db/mysql
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 linux-Jack-nb4 password 'new-password'
See the manual for more instructions.
NOTE: If you are upgrading from a MySQL <= 3.22.10 you should run
the /usr/local/mysql/bin/mysql_fix_privilege_tables. Otherwise you will not be
able to use the new GRANT command!
You can start the MySQL daemon with:
cd /usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &
Please report any problems with the /usr/local/mysql/bin/mysqlbug script!
