Installing MySQL on Solaris Using a Solaris PKG MySQL on Solaris is available in a number of different formats. 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: You might try starting the server with the  --back_log=50  option as a workaround for this. You can install MySQL on Solaris using a binary package of the native Solaris PKG format instead of the binary tarball distribution. 2.7.1 Installing MySQL on Solaris Using a Solaris PKG •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. •If you want to use MySQL with the  mysql  user and group, use the  groupadd  and  useradd  commands: •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: •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: •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. 203 Error in accept: Protocol error pkg install archiver/gnu-tar groupadd mysql useradd -g mysql -s /bin/false mysql Important
