mysql [root@VM_167_102_centos ~]#

结果发现没有，那么我们先下载mysql得rpm包

首先下载server

[root@VM_167_102_centos mysql]# wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-server-5.7.17-1.el7.x86_64.rpm
--2017-04-02 17:51:11--  https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-server-5.7.17-1.el7.x86_64.rpm

然后下载client

 wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-client-5.7.17-1.el7.x86_64.rpm
--2017-04-02 17:55:12--  https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-client-5.7.17-1.el7.x86_64.rpm

然后先安装server

[root@VM_167_102_centos mysql]# rpm -ivh mysql-community-server-5.7.17-1.el7.x86_64.rpm  --nodeps --force
warning: mysql-community-server-5.7.17-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

   1:mysql-community-server-5.7.17-1.e################################# [100%]

然后安装client

[root@VM_167_102_centos mysql]# rpm -ivh mysql-community-client-5.7.17-1.el7.x86_64.rpm --nodeps 
warning: mysql-community-client-5.7.17-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

   1:mysql-community-client-5.7.17-1.e################################# [100%]

然后启动mysql服务

[root@VM_167_102_centos mysql]# service mysqld start
Redirecting to /bin/systemctl start  mysqld.service
[root@VM_167_102_centos mysql]#

获取临时密码

[root@VM_167_102_centos mysql]# grep ‘temporary password‘ /var/log/mysqld.log
2017-04-02T14:55:58.589047Z 1 [Note] A temporary password is generated for root@localhost: k1pki)rKa6HL

然后使用临时密码进入mysql修改密码

[root@VM_167_102_centos mysql]# mysql -uroot -p
Enter password:

mysql>

然后进入etc/my.cnf在[mysqld]下添加一行如下代码

skip-grant-tables

然后在使用刚才得临时密码进入mysql修改root密码

mysql> update mysql.user set authentication_string=password(‘root‘) where user=‘root‘ and Host = ‘localhost‘;
Query OK, 1 row affected, 1 warning (0.00 sec)

然后再把my.cnf文件下刚刚添加得那行代码删除

然后重启mysql

[root@VM_167_102_centos /]# service mysqld restart
Redirecting to /bin/systemctl restart  mysqld.service
[root@VM_167_102_centos /]#

然后就可以使用刚才设置得密码进入mysql了

[root@VM_167_102_centos /]# mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 3

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.

mysql>

设置开机自动重启

[root@VM_167_102_centos /]# systemctl enable mysqld
[root@VM_167_102_centos /]# systemctl daemon-reload

为了确保远程能访问还得增加3306端口开放

这样centos7_64位安装mysql5.7.17就搞定啦。
