ubuntu kylin 14.10下多个mysql 5.7.14安装教程
前文已述,因为需要测试mysql的主从配置方案,所以要安装多个mysql。这次是在ubuntukylin14.10上安装多个mysql5.7.14。
系统环境:ubuntukylin14.10,64位系统
mysql版本:5.7.14社区版
mysql下载地址:http://dev.mysql.com/downloads/mysql/,选择Linux-Generic,下载612.9M的mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz
mysql官方安装文档:http://dev.mysql.com/doc/refman/5.7/en/binary-installation.html1.按照官方安装文档进行即可,只是一些shell命令做了修改,对ubuntu来说,大部分命令都需要在前面增加sudo

2.开始登录mysql进行相关操作
/usr/local/mysql-3306>bin/mysql-uroot-p
注意在执行bin/mysqld初始化时,在命令行最后的提示中给出了一个临时口令,输入之后即可登录。登录mysql之后,要求立即修改密码,否则不能进行任何操作。执行下面的命令修改'root'@'localhost'的密码:
mysql>SETPASSWORD=PASSWORD('yournewpassword'); mysql>ALTERUSER'root'@'localhost'PASSWORDEXPIRENEVER; mysql>flushprivileges;
为了可以远程登录,增加一个'root'@'%'账号:
mysql>grantallprivilegeson*.*to'root'@'%'identifiedby'yournewpassword'withgrantoption;
3.按照上面的办法,继续解压安装mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz,并且配置为3307,3308,3309端口,就可以安装多个mysql了。
