mysql在linux下的安装
安装环境：系统是 centos6.5
1、下载
下载地址：http://dev.mysql.com/downloads/mysql/5.6.html#downloads
下载版本：我这里选择的5.6.33，通用版，linux下64位
也可以直接复制64位的下载地址，通过命令下载：wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
2、解压

5、错误
5.1 sqlyog连接时，报1130错误，是由于没有给远程连接的用户权限问题
解决1:更改 ‘mysql’数据库‘user’表‘host’项，从‘localhost’改成‘%’。
use mysql;
select 'host' from user where user='root';
update user set host = '%' where user ='root';
flush privileges; 解决2：直接授权
GRANT ALL PRIVILEGES ON *.* TO ‘root’@'%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;
5.2 安装时的一些错误
-bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 没有那个文件或目录
解决： yum -y install perl perl-devel
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解决：yum -y install libaio-devel
6、其他
6.1 配置环境变量
vi + /etc/profile
export PATH=....:/usr/local/mysql/bin
