MySQL on Solaris is available in a number of different formats. 

•For information on installing using the native Solaris PKG format, see Section 2.7.1, “Installing MySQL on Solaris Using a Solaris PKG” . 

•To use a standard tar  binary installation, use the notes provided in Section 2.2, “Installing MySQL on Unix/Linux Using Generic Binaries” . Check the notes and hints at the end of this section for Solaris specific notes that you may need before or after installation.

## Important 

The installation packages have a dependency on the Oracle Developer Studio 12.6 Runtime Libraries, which must be installed before you run the MySQL installation package. See the download options for Oracle Developer Studio here. The installation package enables you to install the runtime libraries only instead of the full Oracle Developer Studio; see instructions in Installing Only the Runtime Libraries on Oracle Solaris 11. 

To obtain a binary MySQL distribution for Solaris in tarball or PKG format, https://dev.mysql.com/ downloads/mysql/8.0.html. 

Additional notes to be aware of when installing and using MySQL on Solaris: 

•If you want to use MySQL with the mysql  user and group, use the groupadd  and useradd  commands: 

groupadd mysql useradd -g mysql -s /bin/false mysql 

•If you install MySQL using a binary tarball distribution on Solaris, because the Solaris tar  cannot handle long file names, use GNU tar  ( gtar ) to unpack the distribution. If you do not have GNU tar  on your system, install it with the following command: 

pkg install archiver/gnu-tar 

•You should mount any file systems on which you intend to store InnoDB  files with the forcedirectio option. (By default mounting is done without this option.) Failing to do so causes a significant drop in performance when using the InnoDB  storage engine on this platform. 

•If you would like MySQL to start automatically, you can copy support-files/mysql.server  to / etc/init.d  and create a symbolic link to it named /etc/rc3.d/S99mysql.server . 

•If too many processes try to connect very rapidly to mysqld , you should see this error in the MySQL log: 

Error in accept: Protocol error 

You might try starting the server with the --back_log=50  option as a workaround for this. 

•To configure the generation of core files on Solaris you should use the coreadm  command. Because of the security implications of generating a core on a setuid()  application, by default, Solaris does not support core files on setuid()  programs. However, you can modify this behavior using coreadm . If you enable setuid()  core files for the current user, they are generated using mode 600 and are owned by the superuser. 

## 2.7.1 Installing MySQL on Solaris Using a Solaris PKG 

You can install MySQL on Solaris using a binary package of the native Solaris PKG format instead of the binary tarball distribution.
