MySQL的安装

正式安装MySQL之前，需要安装三个个组件，一个是Cmake（mysql软件的安装编译软件），一个是ncurese（提供终端字符处理库，一个是perl（称为“实用报表提取语言）

两个软件的下载地址为
Cmake: http://www.cmake.org/files/v3.0/cmake-3.0.0.tar.gz 
ncursese:ftp://invisible-island.net/ncurses/ncurses.tar.gz
 http://www.cpan.org/src/5.0/perl-5.20.0.tar.gz
使用tar xzvf解压之后，进行目录，依次使用
shell>./configure 
shell>make
shell>make install
即可成功安装。

正式安装MySQL的安装：
下载地址：http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.19.tar.gz
使用tar xzvf 进入解压缩文件目录。使用如下命令安装：
shell>cmake .
shell>make
shell>make install ，默认安装到/usr/local/mysql目录。
进入安装目录：shell>cd /usr/local/mysql
建立mysql用户和组
shell>groupadd mysql
shell>useradd -r -g mysql mysql
shell> chown -R mysql .
shell>chgrp -R mysql .
shell>scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql --ldata=/var/lib/mysql
shell>chown -R root .
shell>chown -R mysql data
 shell> mkdir /var/run/mysqld
 shell> touch /var/run/mysqld/mysqld.pid
 shell> chown -R mysql:mysql /var/run/mysqld
 shell>chmod -R 755 /var/run/mysqld
shell> bin/mysqld_safe  --user=mysql &
shell> cp support-files/mysql.server /etc/init.d/mysql.server
   

To start mysqld at boot time you have tocopy

support-files/mysql.server to the rightplace for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THEMySQL root USER !

To do so, start the server, then issue thefollowing commands:

  ./bin/mysqladmin -u root password'new-password'

  ./bin/mysqladmin -u root -h server.sanm.orgpassword 'new-password'

Alternatively you can run:

  ./bin/mysql_secure_installation

which will also give you the option ofremoving the testdatabases and anonymous user created by default.  This isstrongly recommended for productionservers.See the manual for more instructions.

You can start the MySQL daemon with:

cd .; ./bin/mysqld_safe &

You can test the MySQL daemon withmysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

WARNING: Default config file /etc/my.cnfexists on the system This file will be read by default by the MySQL server Ifyou do not want to use this, either remove it, or use the --defaults-fileargument to mysqld_safe when starting the server
