centos7 二进制安装包安装 mysql5.6

一、下载mysql5.6二进制安装包

http://mirrors.sohu.com/mysql/MySQL-5.6/

如:mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

二、安装mysql5.6(安装在/data/mysql56)

(1)、创建mysql用户账号

> useradd -s /sbin/nologin -M mysql


(2)、解压压缩包

> tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

 
(3)、重命名

> mv mysql-5.6.34-linux-glibc2.5-x86_64 mysql56

 
(4)、复制配置文件

> cp /data/mysql56/support-files/my-default.cnf /etc/my.cnf

(*二进制安装,默认配置文件在/etc/my.cnf)

(5)、初始化数据库

> chown -R mysql.mysql /data/mysq56> /data/mysql56/scripts/mysql_install_db --user=mysql --basedir=/data/mysql56 --datadir=/data/mysql56/data

如果出现如下信息

FATAL ERROR: please install the following Perl modules before executingData::Dumper
> yum -y install autoconf

此包安装时会安装Data:Dumper模块

三、配置并启动mysql

> cp /data/mysql56/support-files/mysql.server /etc/init.d/mysqld> chmod 755 /etc/init.d/mysqld

(*注意,mysql二进制安装默认的路径为/usr/local/mysql,启动脚本里/usr/local/mysql需要替换)

> sed -i ‘s#/usr/local/mysql#/data/mysql56#g‘ /data/mysql56/bin/mysqld_safe /etc/init.d/mysqld

启动mysql

> service mysqld start

 
四、添加自启动

> chkconfig --add mysqld> chkconfig mysqld on> chkconfig --list mysqld

 
五、配置环境变量

> echo ‘export PATH=/data/mysql56/bin:$PATH‘ >> /etc/profile> source /etc/profile

 
六、修改mysql密码(mysql5.6安装默认root密码为空)

> mysqladmin -u root password ‘123456‘


七、清理无用的mysql用户及库
登陆mysql

> mysql -uroot -p

查询用户

> select user,host from mysql.user;

如下所示

+------+-----------------------+| user | host                  |+------+-----------------------+| root | 127.0.0.1             || root | ::1                   ||      | localhost             || root | localhost             ||      | localhost.localdomain || root | localhost.localdomain |+------+-----------------------+
> drop user "root"@"::1";> drop user ""@"localhost";> drop user ""@"localhost.localdomain";> drop user "root"@"localhost.localdomain";

删除无用库

> drop database test;
