4.4.5 mysql_fix_privilege_tables — Upgrade MySQL System Tables

Some releases of MySQL introduce changes to the structure of the system tables in the mysql database to add new privileges or support new features. When you update to a new version of MySQL, update your system tables as well to make sure that their structure is up to date. Otherwise, there might be capabilities that you cannot take advantage of.

mysql_fix_privilege_tables is an older script that previously was used to uprade the system tables in the mysql database after a MySQL upgrade.

Note

As of MySQL 5.0.19, mysql_fix_privilege_tables is superseded by mysql_upgrade, which should be used instead. See Section 4.4.9, “mysql_upgrade — Check Tables for MySQL Upgrade”.

Before running mysql_fix_privilege_tables, make a backup of your mysql database.

On Unix or Unix-like systems, update the system tables by running the mysql_fix_privilege_tables script:

shell> mysql_fix_privilege_tables

You must run this script while the server is running. It attempts to connect to the server running on the local host as root. If your root account requires a password, indicate the password on the command line like this:

shell> mysql_fix_privilege_tables --password=root_password

The mysql_fix_privilege_tables script performs any actions necessary to convert your system tables to the current format. You might see some Duplicate column name warnings as it runs; you can ignore them.

After running the script, stop the server and restart it so that any changes made to the system tables take effect.

On Windows systems, MySQL distributions include a mysql_fix_privilege_tables.sql SQL script that you can run using the mysql client. For example, if your MySQL installation is located at C:\Program Files\MySQL\MySQL Server 5.0, the commands look like this:

C:\> cd "C:\Program Files\MySQL\MySQL Server 5.0"
C:\> bin\mysql -u root -p mysql
mysql> SOURCE share/mysql_fix_privilege_tables.sql



2. mysql 4.0에서의 올드 패스워드 부분 적용

my.cnf 옵션상의
[mysqld]
old_passwords=1 // 이것만해도됨

secure_auth=0 


3. 마이그레이션 이후 php호환 문제

Cannot load /usr/local/apache/libexec/libphp4.so into server: libmysqlclient.so.12: cannot open shared object file: No such file or directory


php 재컴파일
