CentOS7安装调试Mysql数据库的步骤详解【实例】

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  u2514u250031584 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid...    10u6708 15 11:28:42 agt20.tedu.cn systemd[1]: Starting MySQL Server...  10u6708 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>

至此Mysql数据库安装调试完成!!!!
