2.5.5 Installing MySQL on Linux Using Debian Packages from Oracle

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 2.5.2, “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 (currently, Debian 9, and Ubuntu 16, 17, and 18 are supported). 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

After downloading the tarball, unpack it with the following command:
```
shell> tar -xvf mysql-server_MVER-DVER_CPU.deb-bundle.tar
```
You may need to install the libaio library if it is not already present on your system:
```
shell> sudo apt-get install libaio1
```
Preconfigure the MySQL server package with the following command:
```
shell> sudo dpkg-preconfigure mysql-community-server_*.deb
```
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.

Important

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:
```
shell> sudo dpkg -i mysql-{common,community-client,client,community-server,server}_*.deb
```
There are also packages with server-core and client-core in the package names. These contain binaries only and are installed automatically by the standard packages. Installing them by themselves will not result in a functioning MySQL setup.
If you are being warned of unmet dependencies by dpkg, you can fix them using apt-get:
```
sudo apt-get -f install
```
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 under /var/lib/mysql

Note

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.
