今天LINUX下的MYSQL 启动问题

郁闷中。。。

环境

Red Hat Enterprise Linux AS release 3 (Taroon)
Kernel 2.4.21-4.EL on an i686
login: mysql
Password:
Last login: Sat Mar 24 21:50:07 from 148.20.40.51

按照以下步骤安装的

1. Add a login user and group for `mysqld' to run as:

shell> groupadd mysql
shell> useradd -g mysql mysql

These commands add the `mysql' group and the `mysql' user. The
syntax for `useradd' and `groupadd' may differ slightly on
different versions of Unix. They may also be called `adduser' and
`addgroup'.

You might want to call the user and group something else instead
of `mysql'. If so, substitute the appropriate name in the
following steps.



2. Pick the directory under which you want to unpack the
distribution, and change location into it. In the following
example, we unpack the distribution under `/usr/local'. (The
instructions, therefore, assume that you have permission to create
files and directories in `/usr/local'. If that directory is
protected, you need to perform the installation as `root'.)

shell> cd /usr/local
3. Obtain a distribution file from one of the sites listed in *Note
getting-mysql::. For a given release, binary distributions for all
platforms are built from the same MySQL source distribution.

4. Unpack the distribution, which creates the installation directory.
Then create a symbolic link to that directory:

shell> gunzip < /PATH/TO/MYSQL-VERSION-OS.tar.gz | tar xvf -
shell> ln -s FULL-PATH-TO-MYSQL-VERSION-OS mysql

The `tar' command creates a directory named `mysql-VERSION-OS'.
The `ln' command makes a symbolic link to that directory. This
lets you refer more easily to the installation directory as
`/usr/local/mysql'.

With GNU `tar', no separate invocation of `gunzip' is necessary.
You can replace the first line with the following alternative
command to uncompress and extract the distribution:

shell> tar zxvf /PATH/TO/MYSQL-VERSION-OS.tar.gz

5. Change location into the installation directory:

shell> cd mysql

You can find several files and subdirectories in the `mysql'
directory. The most important for installation purposes are the
`bin' and `scripts' subdirectories.

* `bin'

This directory contains client programs and the server. You
should add the full pathname of this directory to your `PATH'
environment variable so that your shell finds the MySQL
programs properly. See *Note environment-variables::.

* `scripts'

This directory contains the `mysql_install_db' script used to
initialize the `mysql' database containing the grant tables
that store the server access permissions.

6. If you have not installed MySQL before, you must create the MySQL
grant tables:

shell> scripts/mysql_install_db --user=mysql

If you run the command as `root', you should use the -user option
as shown. The value of the option should be the name of the login
account that you created in the first step to use for running the
server. If you run the command while logged in as that user, you
can omit the -user option.

After creating or updating the grant tables, you need to restart
the server manually.

7. Change the ownership of program binaries to `root' and ownership
of the data directory to the user that you run `mysqld' as.
Assuming that you are located in the installation directory
(`/usr/local/mysql'), the commands look like this:

shell> chown -R root .
shell> chown -R mysql data
shell> chgrp -R mysql .

The first command changes the owner attribute of the files to the
`root' user. The second changes the owner attribute of the data
directory to the `mysql' user. The third changes the group
attribute to the `mysql' group.
8. If you would like MySQL to start automatically when you boot your
machine, you can copy `support-files/mysql.server' to the location
where your system has its startup files. More information can be
found in the `support-files/mysql.server' script itself and in
*Note automatic-start::.

9. You can set up new accounts using the `bin/mysql_setpermission'
script if you install the `DBI' and `DBD::mysql' Perl modules. For
instructions, see *Note perl-support::.

10. If you would like to use `mysqlaccess' and have the MySQL
distribution in some non-standard location, you must change the
location where `mysqlaccess' expects to find the `mysql' client.
Edit the `bin/mysqlaccess' script at approximately line 18. Search
for a line that looks like this:

$MYSQL = '/usr/local/bin/mysql'; # path to mysql executable

Change the path to reflect the location where `mysql' actually is
stored on your system. If you do not do this, a `Broken pipe' error
will occur when you run `mysqlaccess'.

After everything has been unpacked and installed, you should test your
distribution.

You can start the MySQL server with the following command:

shell> bin/mysqld_safe --user=mysql &

More information about `mysqld_safe' is given in *Note mysqld-safe::.
*Note*: The accounts that are listed in the MySQL grant tables
initially have no passwords. After starting the server, you should set
up passwords for them using the instructions in *Note
post-installation::.

安装完毕后
