Install mysql5.5 using MySQL Binary Package Based on Linux

Preface

MySQL has been used for some time. However, installation of MySQL is based on the software source on Linux, and then started conveniently using the shell of MySQL, I do not know much about MySQL internal startup parameters, So I download the tar package of MySQL from the MySQL official website, install and start it on my own, and understand MySQLProgramTo help you troubleshoot the startup process and learn more about MySQL.

Environment

Ubuntu 12.04 32bit

Download MySQL

1. Download: Download mysql-5.5.28-linux2.6-i686.tar.gz at http://dev.mysql.com/downloads/mysql/.

2. Extract

 
Tar-Xvf mysql-5.5.28-Linux2.6-I686.Tar. GZ
 

3. Move to/usr/local/MySQL

MVMysql-5.5.28-Linux2.6-I686/usr/local/Ln-S mysql-5.5.28-Linux2.6-I686/MySQL
 

4. Install the dependent lib package: Run/usr/local/bin/MySQL/bin/mysqld, and an error is returned.

 
/Usr/local/MySQL/bin/mysqld: ErrorWhileLoading shared libraries: libaio. So.1: Cannot open sharedObject File: No suchFileOr directory
 

Use apt-cache search libaio to find the following software source:

Libaio-Dev-Linux kernel AIO access library-Development fileslibaio1-Linux kernel AIO access library-Shared librarylibaio1-Dbg-Linux kernel AIO access library-debugging symbols
 

Use apt-Get install libaio1.

 

Configure users and directories

 
Shell>Groupadd mysqlshell> Useradd-r-G MySQL mysqlshell> Cd/usr/local/Mysqlshell>Chown-R mysql. Shell>Chgrp-R MySQL.
 

 

Initialize MySQL

Shell> scripts/mysql_install_db -- user =MySQL
# Next command is optionalshell>CPSupport-files/my-medium.cnf/etc/My. CNF
 

 
# Next command is optionalshell>CPSupport-files/MySQL. Server/etc/init. d/MySQL. Server
 

The most important thing here is to initialize some MySQL permission account tables. A root user with an empty password is created by default.

 

Start MySQL

The simplest startup method:

 
Shell>/Usr/local/MySQL/bin/mysqld -- user = MySQL
 

By default,/usr/local/MySQL/data is used as the MySQL data directory, including database files and log logs.

 

Common MySQL startup parameters:

/Usr/local/MySQL/bin/mysqld -- user = MySQL -- basedir =/usr/local/MySQL -- datadir =/usr/local/MySQL/data -- Port =3306-- Socket =/tmp/MySQL. Sock
 

 

Recommended MySQL startup

 
/Usr/local/MySQL/support-files/MySQL. Server start
 

Generally, the above script is used to start the MySQL server, which can be added to the Linux system service.

 

Disable MySQL

The simplest way

 
KillallMysqld
 

Recommended Methods

 
/Usr/local/MySQL/support-files/MySQL. server stop
 

Using mysql. server stop to close mysqld will destroy the PID file and perform fault tolerance operations. However, the kill command kill MySQL is also called.

Close mysql. Do not use kill-9 mysql_pid or killall-9 mysql. Otherwise, the MySQL process may lose data or even cause table corruption.

 

 

Analysis of MySQL. server script Startup Process

MySQL. server script can be seen in the following script to call the bash mysqld_safe

 
$ Bindir/mysqld_safe -- datadir ="$ Datadir"-- PID-File="$ Mysqld_pid_file_path"$ Other_args>/dev/Null 2> &1&
 

By default, $ bindir/mysqld_safe is the shell/usr/local/MySQL/bin/mysqld_safe. The call parameters of my local machine are as follows:

 
/Bin/Sh/Usr/local/MySQL/bin/mysqld_safe -- datadir =/usr/local/MySQL/data -- PID-File=/Usr/local/MySQL/data/blue-pc.pid
 

Mysqld_safe is also a shell. You can see that after this script initializes n multiple variables, it calls

 
Eval_log_error"$ Cmd"
 

This shell function is called at last.

 
#Echo "Running mysqld: [$ cmd]"Eval"$ Cmd"
 

On my local machine, $ cmd is

 
/Usr/local/MySQL/bin/mysqld -- basedir =/usr/local/MySQL -- datadir =/usr/local/MySQL/data -- Plugin-Dir=/Usr/local/MySQL/lib/plugin -- user = MySQL -- log-error =/usr/local/MySQL/data/blue-pc.err -- PID-File=/Usr/local/MySQL/data/blue-pc.pid
