centos6.9安装mysql5.7

摘要: 现在度娘搜索出来的垃圾太多了,真的不敢苟同了,坑得没法.

在centos 6.9 上rpm安装mysql

环境：

Linux:CentOS release 6.9 64bit

MySQL: mysq-5.7.18

安装前准备

yum search libaio # 检索相关信息
yum install libaio # 安装依赖包

检查 MySQL 是否已安装
yum list installed | grep mysql
如果有，就先全部卸载，命令如下：
yum -y remove mysql-libs.x86_64

1、在/home创建mysql目录，下载如下四个软件包
http://mirrors.sohu.com/mysql/MySQL-5.7/
wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-client-5.7.18-1.el6.x86_64.rpm
wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-common-5.7.18-1.el6.x86_64.rpm
wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-libs-5.7.18-1.el6.x86_64.rpm
wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-server-5.7.18-1.el6.x86_64.rpm
2,同时安装这四个rpm包

rpm -ivh mysql-community-client-5.7.18-1.el6.x86_64.rpm mysql-community-common-5.7.18-1.el6.x86_64.rpm mysql-community-libs-5.7.18-1.el6.x86_64.rpm mysql-community-server-5.7.18-1.el6.x86_64.rpm

3、出现缺少依赖包解决方式

[root@centos-6 home]# rpm -ivh mysql-community-client-5.7.18-1.el6.x86_64.rpm mysql-community-common-5.7.18-1.el6.x86_64.rpm mysql-community-libs-5.7.18-1.el6.x86_64.rpm mysql-community-server-5.7.18-1.el6.x86_64.rpm

warning: mysql-community-client-5.7.18-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

error: Failed dependencies:

libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.18-1.el6.x86_64

libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.18-1.el6.x86_64

libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.18-1.el6.x86_64

[root@centos-6 home]# yum install -y numactl

4、mysql数据库设置

service mysqld stop

mysqld_safe --skip-grant-tables &

mysql -uroot -p

>use mysql;

> update user set authentication_string=PASSWORD("root") where user="root";

update user set host='%' where user="root";

FLUSH PRIVILEGES;

service mysqld restart

mysql -uroot -proot

SET PASSWORD = PASSWORD('root');
