#cd /usr/``local
#tar zxvf /{MySQL5.6_path}/mysql-{version}.tar.gz
例如我的配置路径为：

#tar zxvf /root/mysql-5.6.20-linux-glibc2.5-i686.tar.gz
5：修改解压后文件夹名为 mysql
1
#mv mysql-5.6.20-linux-glibc2.5-i686 mysql
6：修改mysql的各级文件夹和文件的创建者、创建组为mysql（注意语句后面有个**.**）

cd mysql
chown -R mysql .
chgrp -R mysql .
7：至此mysql已经安装完了，但还需要初始化，初始化mysql表、test表、infomation表等。
1
#scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data<br><br>
1
#cp support-files/mysql.server /etc/init.d/mysqld

--user=mysql
--basedir=/usr/local/mysql
--datadir=/usr/local/mysql/data
