本实例要求下载并安装调试Mysql数据库。
第一步：下载Mysql数据库安装所需的全部软件。
我已提前下载好数据库软件，直接在服务器下载即可，如下：
通过scp直接下载：
[root@agt20 ~]# scp root@192.168.122.10:/root/mysql* /root/
软件如下图：
[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：通过yum进行安装，起服务器并查看
[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 Main PID: 31584 (mysqld) CGroup: /system.slice/mysqld.service \u2514\u250031584 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid... 10\u6708 15 11:28:42 agt20.tedu.cn systemd[1]: Starting MySQL Server... 10\u6708 15 11:29:11 agt20.tedu.cn systemd[1]: Started MySQL Server. [root@agt20 ~]#
第三步：连接MySQL服务器，修改密码；
1）查看初始密码
[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）使用初始密码连接mysql服务
[root@agt20 ~]# mysql -uroot -p'r3qhDysMrM)' mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 4 Server version: 5.7.17 Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
3）重置数据库管理员roo本机登录密码
mysql> alter user root@localhost identified by 'Pwd@123...'; Query OK, 0 rows affected (0.00 sec)
4）修改密码策略
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）使用修改后的密码登录
[root@agt20 ~]# mysql -uroot -ppwd@123 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 5 Server version: 5.7.17 MySQL Community Server (GPL) Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql>
