MySQL数据库实验环境

构建MySQL服务器

MySQL安装

环境准备，基本需求

1、创建Linux虚拟机一台

2、配置IP地址

3、关闭firewall

4、禁用SELinux

5、拷贝软件MySQL

6、配置yum源

从官网下载RPM包

—— 下载地址：https://cdn.mysql.com//Downloads

MySQL-5.7.17.tar

数据库安装

1、从官网下载rpm安装包，上传至服务器

root@backup ~]# mkdir mysql

[root@backup ~]# cd /root/mysql

[root@backup mysql]# ls

mysql-5.7.17-1.el7.x86_64.rpm-bundle.tar

2、解压查看

[root@backup mysql]# tar -xf mysql-5.7.17-1.el7.x86_64.rpm-bundle.tar

[root@backup mysql]# ls mysql-community*

mysql-5.7.17-1.el7.x86_64.rpm-bundle.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-server-minimal-5.7.17-1.el7.x86_64.rpm

mysql-community-test-5.7.17-1.el7.x86_64.rpm

注释：

mysql-community-client //客户端应用程序

mysql-community-common //数据库和客户端库共享文件

mysql-community-devel //客户端应用程序的库和头文件

mysql-community- -embedded //嵌入式函数库

mysql-community-embedded-compat //嵌入式兼容函数库

mysql-community- embedded -devel //头文件和库文件作为Mysq|的嵌入式库文件

mysql-community-libs //MySQL数据库客户端应用程序的共享库

mysql-community-libs-compat //客户端应用程序的共享兼容库

3、删除mariadb相关软件包的影响

[root@backup mysql]# yum remove mariadb-libs

4、安装MySQL所需的依赖包

rpm -ivh mysql-community-client-5.7.17-1.el7.x86_64.rpm mysql-community-common-5.7.17-1.el7.x86_64.rpm mysql-community-libs-5.7.17-1.el7.x86_64.rpm mysql-community-server-5.7.17-1.el7.x86_64.rpm

5、启动服务

[root@backup mysql]# systemctl start mysqld

[root@backup mysql]# systemctl enable mysqld

6、初始登录密码

[root@backup mysql]# grep password /var/log/mysqld.log

2021-12-09T10:59:42.534382Z 1 [Note] A temporary password is generated for root@localhost: t>+XEN%%2p?b

[root@backup mysql]# P=`awk '/A temporary/{print $NF}' /var/log/mysqld.log`

[root@backup mysql]# echo $P

t>+XEN%%2p?b

[root@backup mysql]# mysql -uroot -p$P

7、修改root密码

mysql> alter user root@localhost identified by 'MySQL@123';

Query OK, 0 rows affected (0.00 sec)

mysql> exit

Bye

[root@backup mysql]# mysql -uroot -pMySQL@123
