ubuntu手动安装mysql 的一些理解

sudo aptitude install mysql
固然方便，有些时候，还要用源码或者binary安装

一些知识如下：

 sudo ./scripts/mysql_install_db --user=mysql --ldata=/data/mysql --basedir=.

./bin/mysql: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory

sudo aptitude install lib32ncurses5 lib32ncursesw5

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:

./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h ubuntu password 'new-password'

Alternatively you can run:
./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 . ; ./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 with the ./scripts/mysqlbug script!

Installation of system tables failed!  Examine the logs in
/var/lib/mysql for more information.

You can try to start the mysqld daemon with:

    shell> ./bin/mysqld --skip-grant &

and use the command line tool ./bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> ./bin/mysql -u root mysql
    mysql> show tables

Try 'mysqld --help' if you have problems with paths.  Using --log
gives you a log in /var/lib/mysql that may be helpful.
