CentOS6离线安装mysql-5.7.25

1.mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar下载百度云资源

百度云：https://pan.baidu.com/s/1Sfom_aNhTyZnR7KGTZIfFw

提取码：ej1y

2.把下载的mysql安装包上传到Centos上

解压mysql，我这是在Windows上解压的上传到Centos上，我在Centos上解压mysql不知道为什么少了rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm包

tar –vxf mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar

3.查看mysql依赖

1	`rpm -qa \| grep mysql`

4.如果查看有mysql依赖，就删除mysql依赖,

rpm -e --nodeps `rpm -qa | grep mysql`

5.再次查是否有mysql依赖

1	`rpm -qa \| grep mysql`

6.安装一定要按照顺序来

第一个安装： rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm报了一个错误

[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm 
warning: mysql-community-common-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

原因：已存在MariaDB-common-10.4.8-1.el7.centos.x86_64的库（这是我以前安装MariaDB数据库，如果是别的也要根据对应的名字删除），所以需要先删除以前的库才能安装！

执行强制卸载命令：

1	`rpm -e MariaDB-common-10.4.8-1.el7.centos.x86_64--nodeps`

然后查看：

1	`rpm –qa \| grep mysql`

再继续安装

1	`rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm`

[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm 
warning: mysql-community-common-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
Preparing...                ########################################### [100%]

第二个安装：

1	`rpm -ivh mysql-community-libs-5.7.25-1.el6.x86_64.rpm`

[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-libs-5.7.25-1.el6.x86_64.rpm 
warning: mysql-community-libs-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
Preparing...                ########################################### [100%]
   1:mysql-community-libs   ########################################### [100%]

第三个安装

1	`rpm -ivh mysql-community-client-5.7.25-1.el6.x86_64.rpm`

[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-client-5.7.25-1.el6.x86_64.rpm 
warning: mysql-community-client-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

   1:mysql-community-client ########################################### [100%]

第四个安装

1	`rpm -ivh mysql-community-server-5.7.25-1.el6.x86_64.rpm`

[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-server-5.7.25-1.el6.x86_64.rpm

You have new mail in /var/spool/mail/root

第五个安装

1	`rpm -ivh mysql-community-devel-5.7.25-1.el6.x86_64.rpm`

[root@localhost mysql-5.7.25]# rpm -ivh mysql-community-devel-5.7.25-1.el6.x86_64.rpm 
warning: mysql-community-devel-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

7.使用命令启动mysql服务

1	`service mysqld start`

[root@localhost mysql-5.7.25]# service mysqld start
Starting mysqld:  [  OK  ]
[root@localhost mysql-5.7.25]#

8.使用命令生成一个随机密码：grep "temporary password" /var/log/mysqld.log

[root@localhost mysql-5.7.25]# grep "temporary password" /var/log/mysqld.log
2020-04-07T12:32:39.276158Z 1 [Note] A temporary password is generated for root@localhost: >v>uyo:fg7.O
[root@localhost mysql-5.7.25]#

注意：密码是root@localhost:右边的字符串

root@localhost: >v>uyo:fg7.O 这里生成的随机密码是：>v>uyo:fg7.O

MySQL 会在 /var/log/mysqld.log 日志中生成一个随机密码，默认需要修改密码才能使用

可以通过 vim /var/log/mysqld.log 打开里面有一行这样的代码

1	`2020-04-07T12:32:39.276158Z 1 [Note] A temporary password` `is` `generated` `for` `root@localhost: >v>uyo:fg7.O`

9.修改密码，先登录mysql

1	`mysql -u root –p`

1 2	`[root@localhost mysql-5.7.25]# mysql -u root -p` `Enter password:`

我这随机密码就是：>v>uyo:fg7.O

10.登录成功

[root@localhost log]# mysql -u root -p
Enter password:

11.修改密码：

1	`mysql> ALTER USER` `'root'@'localhost'` `IDENTIFIED BY` `'新密码';`

12.设置权限

　　为了可以远程连接该数据库，需要设置相应的权限

#任何主机
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '刚刚修改的密码' WITH GRANT OPTION;
#指定主机
mysql>GRANT ALL PRIVILEGES ON *.* TO 'xxxx'@’xx.xx.xx.xx’ IDENTIFIED BY 'xxxx' WITH GRANT OPTION;
