上传文件mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar到服务器上。

切换到上传文件目录下运行如下命令:

[root@gelong-vm1 rpms]# tar -vxf mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar
mysql-community-libs-8.0.18-1.el7.x86_64.rpm
mysql-community-devel-8.0.18-1.el7.x86_64.rpm
mysql-community-embedded-compat-8.0.18-1.el7.x86_64.rpm
mysql-community-libs-compat-8.0.18-1.el7.x86_64.rpm
mysql-community-common-8.0.18-1.el7.x86_64.rpm
mysql-community-test-8.0.18-1.el7.x86_64.rpm
mysql-community-server-8.0.18-1.el7.x86_64.rpm
mysql-community-client-8.0.18-1.el7.x86_64.rpm

1.检查系统自带的 MariaDB

检查系统是否自带MariaDB,命令如下:

rpm -qa | grep mariadb

如果系统自带MariaDB,删除掉,删除命令如下:

rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64

2.检查系统自带的mysql数据库安装包

检查系统是否自带Mysql数据库,名利如下:

rpm -qa | grep mysql

如果系统自带mysql数据库,删除掉,删除命令如下:

rpm -e --nodeps mysql-libs-5.1.73-8.el6_8.x86_64

按照如下顺序安装:

rpm -ivh mysql-community-common-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-8.0.18-1.el7.x86_64.rpm

1.安装mysql-community-server-8.0.18-1.el7.x86_64.rpm 报错解决方案

安装 mysql-community-server-8.0.18-1.el7.x86_64.rpm 的时候需要依赖 net-tools,如果没有 net-tools 会安装失败,此时先安装 net-tools,然后再安装 mysql-community-server-8.0.18-1.el7.x86_64.rpm 即可,安装命令如下:

# 安装 mysql-community-server-8.0.25-1.el7.x86_64.rpm 依赖报错

2.安装 rpm -ivh mysql-community-devel-8.0.18-1.el7.x86_64.rpm 报错解决方案

[root@192 mysql]# rpm -ivh mysql-community-devel-8.0.18-1.el7.x86_64.rpm

解决办法

yum install openssl-devel

[blockquote1 name=’洛维花’]在MySQL8中,数据目录初始化之后,不再允许更改lower_case_table_names=1的值;也就是说启动(重启)MYSQL时,lower_case_table_names的值必须于,初始化MYSOL时(安装 MYSOL后的首次启动)的值相同。[/blockquote1]
由于我的业务是有需求的,所以我先设置关闭大小写验证

#进入目录
cd /etc/
#编辑my.cnf文件
vi /etc/my.cnf
#添加内容
lower_case_table_names=1

通常,0 表示大小写敏感,1 表示大小写不敏感。
相关文章:
CentOS 上查看 MySQL 的大小写敏感状态
centos 安装MySQL 8.0 区分大小写解决方法

1.启动MYSQL服务:

[root@gelong-vm1 rpms]# service mysqld start
Redirecting to /bin/systemctl start mysqld.service

2.查看启动状态:

[root@gelong-vm1 rpms]# systemctl status mysqld.service
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
   Active: active (running) since 二 2023-09-05 14:19:46 CST; 38s ago

9月 05 14:19:46 gelong-vm1 systemd[1]: Started MySQL Server.

1.查看默认密码:

查看默认密码命令如下

[root@gelong-vm1 rpms]# grep 'temporary password' /var/log/mysqld.log
2023-09-05T06:19:39.121134Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: iU/%Q(3w<AO*

2.使用默认密码登录mysql:

[root@gelong-vm1 rpms]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8

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

3.修改 root 用户密码:

注意:这里修改的密码要足够复杂,包含大小和特殊符号;

mysql> alter user 'root'@'localhost' identified by 'Houpu123!@#';
Query OK, 0 rows affected (0.62 sec)
 
mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.23    |
+-----------+
1 row in set (0.00 sec)

4.修改 root 用户的 host 列值,开启远程连接:

修改运行远程连接命令如下:

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> UPDATE user SET `Host` = '%' WHERE `User` = 'root' LIMIT 1;
Query OK, 1 row affected (0.01 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> select host from user;
+-----------+
| host      |
+-----------+
| %         |
| localhost |
| localhost |
| localhost |
+-----------+
4 rows in set (0.00 sec)

5.刷新缓存:

重新刷新mysql的缓存内容命令:

mysql> flush privileges;
Query OK, 0 rows affected (0.47 sec)
 

6.给 root 用户授予所有权限:

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;
Query OK, 0 rows affected (0.02 sec)
 

解决远程连接时报错

2059-Authentication plugin ‘caching_sha2_password‘
      出现原因

安装的时候,选择了强加密规则caching_sha2_password,与之前的mysqlmysql_native_password规则不同,navicate驱动目前不支持新加密规则
【环境安装记录指定Mysql版本篇】CentOS7 离线安装mysql8数据库

      解决方法

通过更改加密规则和刷新权限的方式

use mysql; #选择数据库
# 远程连接请将'%'换成'localhost'
ALTER USER 'root'@'%' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; #更改加密方式
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'password'; #更新用户密码
FLUSH PRIVILEGES; #刷新权限

8.退出mysql控制台:

exit;
