1. Install Mysql Server Linux

Oracle provides Debian packages for installing MySQL on Debian or Debian-like Linux systems. The packages are available through two different channels:

• The MySQL APT Repository. This is the preferred method for installing MySQL on Debian-like systems, as it provides a simple and convenient way to install and update MySQL products. For details, see Section 2.5.3, “Installing MySQL on Linux Using the MySQL APT Repository”.

• The MySQL Developer Zone's Download Area. For details, see Section 2.1.2, “How to Get MySQL”. The following are some information on the Debian packages available there and the instructions for installing them:

  • Various Debian packages are provided in the MySQL Developer Zone for installing different components of MySQL on different Debian or Ubuntu platforms. The preferred method is to use the tarball bundle, which contains the packages needed for a basic setup of MySQL. The tarball bundles have names in the format of mysql-server_MVER-DVER_CPU.deb-bundle.tar. MVER is the MySQL version and DVER is the Linux distribution version. The CPU value indicates the processor type or family for which the package is built, as shown in the following table:

    Table 2.12 MySQL Debian and Ubuntu Installation Packages CPU Identifiers

    CPU Value	Intended Processor Type or Family
    i386	Pentium processor or better, 32 bit
    amd64	64-bit x86 processor

    
    

  • Zero shinku no chou wii download. After downloading the tarball, unpack it with the following command:

  • You may need to install the libaio library if it is not already present on your system:

  • Preconfigure the MySQL server package with the following command:

    You will be asked to provide a password for the root user for your MySQL installation. You might also be asked other questions regarding the installation.

    Make sure you remember the root password you set. Users who want to set a password later can leave the password field blank in the dialogue box and just press OK; in that case, root access to the server is authenticated using the MySQL Socket Peer-Credential Authentication Plugin for connections using a Unix socket file. You can set the root password later using mysql_secure_installation.

  • For a basic installation of the MySQL server, install the database common files package, the client package, the client metapackage, the server package, and the server metapackage (in that order); you can do that with a single command:

    If you are being warned of unmet dependencies by dpkg, you can fix them using apt-get:

    Here are where the files are installed on the system:

    • All configuration files (like my.cnf) are under /etc/mysql

    • All binaries, libraries, headers, etc., are under /usr/bin and /usr/sbin

    • The data directory is /var/lib/mysql

Debian distributions of MySQL are also provided by other vendors. Be aware that they may differ from those built by Oracle in features, capabilities, and conventions (including communication setup), and that the instructions in this manual do not necessarily apply to installing them. The vendor's instructions should be consulted instead.

Many Linux distributions include a version of the MySQL server, client tools, and development components in their native software repositories and can be installed with the platforms' standard package management systems. This section provides basic instructions for installing MySQL using those package management systems.

Install Mysql Server Linux

Native packages are often several versions behind the currently available release. You will also normally be unable to install development milestone releases (DMRs), as these are not usually made available in the native repositories. Before proceeding, we recommend that you check out the other installation options described in Section 2.5, “Installing MySQL on Linux”.

Distribution specific instructions are shown below:

• Red Hat Linux, Fedora, CentOS

  Pc running slow help. For a number of Linux distributions, you can install MySQL using the MySQL Yum repository instead of the platform's native software repository. See Section 2.5.1, “Installing MySQL on Linux Using the MySQL Yum Repository” for details.

  For Red Hat and similar distributions, the MySQL distribution is divided into a number of separate packages, mysql for the client tools, mysql-server for the server and associated tools, and mysql-libs for the libraries. The libraries are required if you want to provide connectivity from different languages and environments such as Perl, Python and others.

  To install, use the yum command to specify the packages that you want to install. For example:

  MySQL and the MySQL server should now be installed. A sample configuration file is installed into /etc/my.cnf. An init script, to start and stop the server, will have been installed into /etc/init.d/mysqld. To start the MySQL server use service:

  To enable the server to be started and stopped automatically during boot, use chkconfig:

  Which enables the MySQL server to be started (and stopped) automatically at the specified the run levels.

  The database tables will have been automatically created for you, if they do not already exist. You should, however, run mysql_secure_installation to set the root passwords on your server.

• Debian, Ubuntu, Kubuntu

  On Debian, Ubuntu, and Kubuntu, MySQL can be installed using the MySQL APT Repository instead of the platform's native software repository. See Section 2.5.3, “Installing MySQL on Linux Using the MySQL APT Repository” for details.

  On Debian and related distributions, there are two packages for MySQL in their software repositories, mysql-client and mysql-server, for the client and server components respectively. You should specify an explicit version, for example mysql-client-5.1, to ensure that you install the version of MySQL that you want.

  To download and install, including any dependencies, use the apt-get command, specifying the packages that you want to install.

  Before installing, make sure that you update your apt-get index files to ensure you are downloading the latest available version.

  A sample installation of the MySQL packages might look like this (some sections trimmed for clarity):

  The apt-get command will install a number of packages, including the MySQL server, in order to provide the typical tools and application environment. This can mean that you install a large number of packages in addition to the main MySQL package.

  During installation, the initial database will be created, and you will be prompted for the MySQL root password (and confirmation). A configuration file will have been created in /etc/mysql/my.cnf. An init script will have been created in /etc/init.d/mysql.

  The server will already be started. You can manually start and stop the server using:

  The service will automatically be added to the 2, 3 and 4 run levels, with stop scripts in the single, shutdown and restart levels.
