MySQL - Installation

Installing MySQL 3.23 - (Linux)

---

Overview
The following article provides the steps necessary to successfully install the binary version of MySQL, release 3.23, on RedHat Linux 8.0. These procedures should work as well on versions of RedHat as early as version 6.2.
I typically install MySQL in /usr/local/mysql as the UNIX root account. I then create a UNIX mysql account that will have access to manage databases.
Once you've installed MySQL, you will need to initialize the grant tables, start the server, and make sure that the server works okay. You may also elect to arrange for the server to be started and stopped automatically when your system starts up and shuts down.
Installing the grant tables is accomplished by running the mysql_install_db script. This creates the mysql database which will hold all database privileges, thetest database which you can use to test MySQL, and also privilege entries for the user that run mysql_install_db and a root user (without any passwords).

Operating System Account
Create MySQL User Account:
% groupadd -g 116 mysql
% useradd -u 174 -c "MySQL Software Owner" \
-d /u01/app/mysql -g "mysql" -m -s /bin/bash mysql
% passwd mysql
Create MySQL UserID:
% mkdir /u01
% mkdir /u01/app
% mkdir /u01/app/mysql
% chown -R mysql:mysql /u01/app/mysql

Uncompress / Installing Binary Version of MySQL
% su -
% cp mysql-3.23.54-pc-linux-i686.tar /usr/local
% cd /usr/local
% gunzip mysql-3.23.54-pc-linux-i686.tar.gz
% tar xvf mysql-3.23.54-pc-linux-i686.tar
% ln -s mysql-3.23.54-pc-linux-i686 mysql
% cd mysql
% scripts/mysql_install_db
% chown -R root .
% chown -R mysql data
% chgrp -R mysql .

Starting and Stopping the MySQL Database Software
Starting the MySQL Database
% bin/safe_mysqld --user=mysql &
Stopping the MySQL Database
% bin/mysqladmin -u root shutdown

NOTE:

The safe_mysqld startup script of MySQL 3.23.54 includes a small bug that leads to a "syntax error" message on startup. Here is a quick hint on how to fix it: Open bin/safe_mysqld with a text editor. Go to line 162 and look for the following text: if $NOHUP_NICENESS -gt 0 then $NOHUP_NICENESS="nice --$NOHUP_NICENESS nohup" Change it to look like this: if test $NOHUP_NICENESS -gt 0 then NOHUP_NICENESS="nice --$NOHUP_NICENESS nohup" (Make sure to add "test" to the if-statement and remove the dollar sign from the $NOHUP_NICENESS= line) This error will be fixed for MySQL 3.23.54a, which will be released shortly.

Testing the Installation
Ensure that the MySQL Software, the mysqld server, is running and you have set up the initial MySQL grant tables containing the privileges that determine how users are allowed to connect to the server. This is normally done with the mysql_install_db script.

• Using mysqladmin
• % mysqladmin ping
