1.修改yum源
鉴于用国外的Yum源，速度比较慢，所以想到将国外的yum源改为国内的Yum源，这里选择使用比较多的阿里云源。具体修改方法可以参考此连接
我们先新建一个新的文件用来存放Yum源：
下载新的CentOS-Base.repo 到/etc/yum.repos.d/：
[kfk@bigdata-pro01 yum.repos.d]$ sudo wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
--2019-03-21 09:19:23-- http://mirrors.aliyun.com/repo/Centos-6.repo

[kfk@bigdata-pro01 yum.repos.d]$ cd /etc/yum.repos.d
[kfk@bigdata-pro01 yum.repos.d]$ ls
CentOS-Base CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
[kfk@bigdata-pro01 yum.repos.d]$ yum makecache //生成缓存

然后在notepad++里打开我们下载的文件，然后将其中的内容拷贝到我们刚才新建的文件中去。
粘贴内容，然后保存退出。

[kfk@bigdata-pro01 yum.repos.d]$ which mysql /usr/bin/mysql
3.mysql 服务启动并测试
1）查看mysql服务状态
[kfk@bigdata-pro01 yum.repos.d]$ service mysqld status mysqld is stopped
2）启动mysql服务
[kfk@bigdata-pro01 yum.repos.d]$ sudo service mysqld start Initializing MySQL database: Installing MySQL system tables... OK Filling help tables... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system 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 bigdata-pro01.kfk.com password 'new-password' Alternatively you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd /usr ; /usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd /usr/mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/bin/mysqlbug script! [ OK ] Starting mysqld: [ OK ]
3）设置mysql密码
[kfk@bigdata-pro01 yum.repos.d]$ /usr/bin/mysqladmin -u root password 'root'
4）连接mysql
[kfk@bigdata-pro01 yum.repos.d]$ mysql -u root -proot Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 4 Server version: 5.1.73 Source distribution Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.
