下载地址

ftp://mirror.switch.ch/mirror/mysql/Downloads/MySQL-5.6/mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz

解压

tar -xzf mysql-5.6.-linux-glibc2.-x86_64.tar.gz

注：安装目录需要设置到解压目录，否则报以下错误

FATAL ERROR: Could not find ./bin/my_print_defaults

If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.

If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.

or

FATAL ERROR: Could not find my-default.cnf

If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.

If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.

将解压的目录放到/usr/local下改为mysql或添加软连接

mv mysql-5.6.-linux-glibc2.-x86_64 mysql

or

ln -s  /www/mysql-5.6.-linux-glibc2.-x86_64 /usr/local/mysql

增加mysql用户和组

groupadd mysql
useradd -r -g mysql mysql

修改mysql目录及子文件属主和属组

chown -R mysql:mysql mysql

进入mysql目录并安装

cd mysql
scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/var/lib/mysql

安装过程可能缺少某些文件，一般用 yum install -y xxx 按需安装即可.

实现使用 service mysqll (start|status|stop) 命令操作mysql.

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

错误：

[root@localhost mysql]# mysql
-bash: mysql: command not found

解决：配置环境变量，把 export PATH=$PATH:/usr/local/mysql/bin添加到 /etc/profile中， source /etc/profile重新加载环境变量， service mysql start启动mysql服务。

错误：

[root@localhost mysql]# mysql
ERROR  (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

解决：

mysql --socket=/var/lib/mysql/mysql.sock
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

启动成功

mysql> select version();
+-----------+
| version() |
+-----------+
| 5.6. |
+-----------+
 row in set (0.00 sec)

成功后可能需要往mysql的user表增加新账号

错误：指定了严格模式，为了安全，严格模式禁止通过insert 这种形式直接修改mysql库中的user表进行添加新用户

 - Field 'ssl_cipher' doesn't have a default value

解决：

vim /usr/local/mysql/my.cnf

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
改为
sql_mode=NO_ENGINE_SUBSTITUTION
