Linux下基于源代码方式安装MySQL 5.6

MySQL为开源数据库，因此能够基于源代码实现安装。基于源代码安装有很多其它的灵活性。

也就是说我们能够针对自己的硬件平台选用合适的编译器来优化编译后的二进制代码。依据不同的软件平台环境调整相关的编译參数。选择自身须要选择不同的安装组件，设定须要的字符集等等一些能够依据特定应用场景所作的各种调整。本文描写叙述了怎样在源代码方式下安装MySQL。

1、安装环境及介质
#安装环境
SZDB:~ # cat /etc/issue
Welcome to SUSE Linux Enterprise Server 10 SP3 (x86_64) - Kernel \r (\l).
SZDB:~ # uname -a
Linux SZDB 2.6.16.60-0.54.5-smp #1 SMP Fri Sep 4 01:28:03 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux

#安装介质。能够到以下网址下载安装介质。注意下载时选择source code。当前版本号为5.6.17
#依据你自身的环境下载相应的安装介质，本文演示的安装介质为Generic Linux (Architecture Independent), mysql-5.6.17.tar.gz
http://dev.mysql.com/downloads/mysql/

#源代码安装方式官方站点链接: http://dev.mysql.com/doc/refman/5.6/en/installing-source-distribution.html

2、系统需求
Source Installation System Requirements

Installation of MySQL from source requires several development tools. Some of these tools are needed no matter whether you use a standard source distribution or a development source tree. Other tool requirements depend on which installation method you use.

To install MySQL from source, your system must have the following tools, regardless of installation method:

• CMake, which is used as the build framework on all platforms. CMake can be downloaded from http://www.cmake.org.
• A good make program. Although some platforms come with their own make implementations, it is highly recommended that you use GNU make 3.75 or newer. It may already be available on your system as gmake. GNU make is available from http://www.gnu.org/software/make/.
• A working ANSI C++ compiler. GCC 4.2.1 or later, Sun Studio 12 or later, Visual Studio 2010 or later, and many current vendor-supplied compilers are known to work.
• Perl is needed if you intend to run test scripts. Most Unix-like systems include Perl. On Windows, you can use a version such as ActiveState Perl.

#使用源代码安装上面的一些开发工具是须要的，比較重要的一个是Cmake工具。通常情况下os并没有安装。须要手动安装。
#假设没有cmake会收到这个错误提示：(-bash: cmake: command not found)

3、安装cmake
#能够到这里下载cmake，我这里下载的是2.6.4版本号
http://www.cmake.org/cmake/resources/software.html
SZDB:~ # cd /usr/local/src/mysql_src
SZDB:/usr/local/src/mysql_src # tar -xvf cmake-2.6.4.tar.gz
SZDB:/usr/local/src/mysql_src # cd cmake-2.6.4
SZDB:/usr/local/src/mysql_src/cmake-2.6.4 # ./bootstrap 
SZDB:/usr/local/src/mysql_src/cmake-2.6.4 # ./make
SZDB:/usr/local/src/mysql_src/cmake-2.6.4 # ./make install

4、安装MySQL
SZDB:~ # groupadd mysql
SZDB:~ # useradd -r -g mysql mysql
SZDB:~ # cd /usr/local/src/mysql_src
SZDB:/usr/local/src/mysql_src # tar -xvf mysql-5.6.17.tar.gz
SZDB:/usr/local/src/mysql_src # ls
mysql-5.6.17  mysql-5.6.17.tar.gz
SZDB:/usr/local/src/mysql_src # cd mysql-5.6.17/
SZDB:/usr/local/src/mysql_src/mysql-5.6.17 # cmake .

..........
    To start mysqld at boot time you have to copy
    support-files/mysql.server to the right place for your system
    
    PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
    To do so, start the server, then issue the following commands:
    
      ./bin/mysqladmin -u root password 'new-password'
      ./bin/mysqladmin -u root -h SZDB password 'new-password'
    
    Alternatively you can run:
    
      ./bin/mysql_secure_installation
    
    which will also give you the option of removing the test
    databases and anonymous user created by default.  This is
    strongly recommended for production servers.
    
    See the manual for more instructions.
    
    You can start the MySQL daemon with:
    
      cd . ; ./bin/mysqld_safe &
    
    You can test the MySQL daemon with mysql-test-run.pl
    
      cd mysql-test ; perl mysql-test-run.pl
   
    New default config file was created as ./my.cnf and
    will be used by default by the server when you start it.
    You may edit this file to change server settings
