CDH准备（CentOS7安装MySQL）

#CentOS7安装MySQL

1.安装前准备

1）下载地址：https://downloads.mysql.com/archives/community/

2）卸载系统自带的mariaDB

[root@cdhmaster Desktop]# rpm -qa|grep mariadb

mariadb-libs-5.5.44-2.el7.centos.x86_64

[root@cdhmaster Desktop]# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64

3）安装autoconf包

yum -y install autoconf //此包安装时会安装Data:Dumper模块

不安装此包安装mysql时会报以下错：

FATAL ERROR: please install the following Perl modules before executing /usr/bin/mysql_install_db:

Data::Dumper

...

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

 

/usr/bin/mysqladmin -u root password 'new-password'

/usr/bin/mysqladmin -u root -h cdhmaster password 'new-password'

...

启动mysql服务

[root@cdhmaster mysql]# service mysql start

Starting MySQL. SUCCESS!

[root@cdhmaster mysql]#

配置root密码

[root@cdhmaster mysql]# mysqladmin -u root password '你的密码'

Warning: Using a password on the command line interface can be insecure.

这样就配置完了，就能够用mysql -uroot -p登陆了，以下所示：

[root@cdhmaster mysql]# mysql -uroot -p

Enter password:
