1、下載地址 wget http://downloads.mysql.com/archives/get/file/mysql-5.6.27-linux-glibc2.5-x86_64.tar.gz


2、安裝說明 http://dev.mysql.com/doc/refman/5.6/en/binary-installation.html

3、安裝步驟：

shell> groupadd mysql
shell> useradd -r -g mysql -s /bin/false mysql
shell> cd /usr/local
shell> tar zxvf /path/to/mysql-VERSION-OS
 
.tar.gz
shell> ln -s full-path-to-mysql-VERSION-OS mysql
shell> cd mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
shell> bin/mysqld_safe --user=mysql &
# Next command is optional
shell> cp support-files/mysql.server /etc/init.d/mysql.server
 

4、安裝完成後，設定root密碼(安裝很多遍，一直沒仔細看過這個說明)

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 localhost.localdomain 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
 

提示mysql命令不存在：ln -s /usr/local/mysql/bin/mysql /usr/bin

5、安裝後，用/usr/local/mysql/bin/mysql -u root -p 進入報錯/usr/local/mysql/bin/mysql: unknown variable 'datadir=/data1/mysql/var/' 

這裡需要修改my.cnf  配置問題 ：

[client]#password        = your_passwordport                = 3306socket                = /tmp/mysql.sockdatadir         = /data1/mysql/var/  #把這裡已到下方mysqld部分裡[mysqld]port                = 3306socket                = /tmp/mysql.sockdatadir         = /data1/mysql/var/  #加這裡
