本實例要求下載并安裝調試Mysql數據庫。
第一步：下載Mysql數據庫安裝所需的全部軟件。
我已提前下載好數據庫軟件，直接在服務器下載即可，如下：
通過scp直接下載：
[root@agt20 ~]# scp root@192.168.122.10:/root/mysql* /root/
軟件如下圖：
[root@agt20 ~]# ls mysql-*
mysql-5.7.17.tar
mysql-community-client-5.7.17-1.el7.x86_64.rpm
mysql-community-common-5.7.17-1.el7.x86_64.rpm
mysql-community-devel-5.7.17-1.el7.x86_64.rpm
mysql-community-embedded-5.7.17-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.17-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.17-1.el7.x86_64.rpm
mysql-community-libs-5.7.17-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.17-1.el7.x86_64.rpm
mysql-community-minimal-debuginfo-5.7.17-1.el7.x86_64.rpm
mysql-community-server-5.7.17-1.el7.x86_64.rpm
mysql-community-test-5.7.17-1.el7.x86_64.rpm
第二步：通過yum進行安裝，起服務器并查看
[root@agt20 ~]# yum -y install mysql-*.rpm
[root@agt20 ~]# systemctl restart mysqld
[root@agt20 ~]# systemctl enable mysqld
[root@agt20 ~]# systemctl status mysqld.service
\u25cf mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
Active: active (running) since \u4e8c 2019-10-15 11:29:11 CST; 1min 15s ago
Docs: man:mysqld(8)
http://dev.mysql.com/doc/refman/en/using-systemd.html

CGroup: /system.slice/mysqld.service

10\u6708 15 11:29:11 agt20.tedu.cn systemd[1]: Started MySQL Server.
[root@agt20 ~]#
第三步：連接MySQL服務器，修改密碼；
1）查看初始密碼
[root@agt20 ~]# grep -i 'password' /var/log/mysqld.log
2019-10-15T03:28:55.200931Z 1 [Note] A temporary password is generated for root@localhost: r3qhDysMrM)
2）使用初始密碼連接mysql服務
[root@agt20 ~]# mysql -uroot -p'r3qhDysMrM)'
mysql: [Warning] Using a password on the command line interface can be insecure.

3）重置數據庫管理員roo本機登錄密碼
mysql> alter user root@localhost identified by 'Pwd@123...';
Query OK, 0 rows affected (0.00 sec)
4）修改密碼策略
mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.01 sec)
mysql> set global validate_password_length=6;
Query OK, 0 rows affected (0.00 sec)
mysql> alter user root@localhost identified by 'pwd@123';
Query OK, 0 rows affected (0.00 sec)
5）使用修改后的密碼登錄
[root@agt20 ~]# mysql -uroot -ppwd@123
mysql: [Warning] Using a password on the command line interface can be insecure.
