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ubuntu kylin 14.10上安装多个mysql 5.7.14。

系统环境:ubuntu kylin 14.10,64位系统 mysql版本:5.7.14社区版 mysql下载地址:,选择 Linux - Generic,下载612.9M的mysql-5.7.14-linux-glibc2.5-x86_64.tar.gzmysql官方安装文档: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

shell sudo groupadd mysqlshell sudo useradd -r -g mysql -s /bin/false mysqlshell cd /usr/localshell sudo tar -zxvf /path/to/mysql-VERSION-OS.tar.gzshell sudo mv mysql-5.7.14-linux-glibc2.5-x86_64 mysql-5.7.14-linux-glibc2.5-x86_64-3306 #将mysql的目录改了一下名shell sudo ln -s mysql-5.7.14-linux-glibc2.5-x86_64-3306 mysql-3306shell cd mysql-3306shell sudo mkdir mysql-filesshell sudo chmod 750 mysql-filesshell sudo chown -R mysql:mysql .shell sudo cp support-files/my-default.cnf ./my.cnf #copy一份my.cnf接着编辑my.cnf,打开basedir,datadir,port等项,按如下配置:basedir = /usr/local/mysql-3306datadir = /usr/local/mysql-3306/dataport = 3306server_id = 11然后开始初始化3306端口上的mysql:shell sudo bin/mysqld --defaults-file=/usr/local/mysql-3306/my.cnf --initialize --user=mysql2016-07-29T15:38:48.896585Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

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 SET PASSWORD = PASSWORD('your new password');mysql ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;mysql flush privileges;

为了可以远程登录,增加一个'root'@'%'账号:

复制代码 代码如下:mysql grant all privileges on *.* to 'root'@'%' identified by 'your new password' with grant option;

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。
