1.mysql-5.7.25-1.el6.x86_64.rpm-bundle.tar下載百度雲資源
百度雲：https://pan.baidu.com/s/1Sfom_aNhTyZnR7KGTZIfFw
提取碼：ej1y
2.把下載的mysql安裝包上傳到Centos上
解壓mysql，我這是在Windows上解壓的上傳到Centos上，我在Centos上解壓mysql不知道為什么少了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依賴
rpm -qa | grep mysql
4.如果查看有mysql依賴，就刪除mysql依賴,
rpm -e --nodeps `rpm -qa | grep mysql`
5.再次查是否有mysql依賴
rpm -qa | grep mysql
6.安裝一定要按照順序來
第一個安裝： rpm -ivh mysql-community-common-5.7.25-1.el6.x86_64.rpm報了一個錯誤
[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的庫（這是我以前安裝MariaDB數據庫，如果是別的也要根據對應的名字刪除），所以需要先刪除以前的庫才能安裝！
執行強制卸載命令：
rpm -e MariaDB-common-10.4.8-1.el7.centos.x86_64--nodeps
然后查看：
rpm –qa | grep mysql
再繼續安裝
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%] 1:mysql-community-common ########################################### [100%]
第二個安裝：
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%]
第三個安裝
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 Preparing... ########################################### [100%] 1:mysql-community-client ########################################### [100%]
第四個安裝
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 warning: mysql-community-server-5.7.25-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-community-server ########################################### [100%] You have new mail in /var/spool/mail/root
第五個安裝
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 Preparing... ########################################### [100%] 1:mysql-community-devel ########################################### [100%]
7.使用命令啟動mysql服務
service mysqld start
[root@localhost mysql-5.7.25]# service mysqld start Starting mysqld: [ OK ] [root@localhost mysql-5.7.25]#
8.使用命令生成一個隨機密碼：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：密碼是root@localhost:右邊的字符串
root@localhost: >v>uyo:fg7.O 這里生成的隨機密碼是：>v>uyo:fg7.O
MySQL 會在 /var/log/mysqld.log 日志中生成一個隨機密碼，默認需要修改密碼才能使用
可以通過 vim /var/log/mysqld.log 打開里面有一行這樣的代碼
2020-04-07T12:32:39.276158Z 1 [Note] A temporary password is generated for root@localhost: >v>uyo:fg7.O
9.修改密碼，先登錄mysql
mysql -u root –p
[root@localhost mysql-5.7.25]# mysql -u root -p Enter password:
我這隨機密碼就是：>v>uyo:fg7.O
10.登錄成功
[root@localhost log]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 12 Server version: 5.7.25 Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'wangqing'; Query OK, 0 rows affected (0.01 sec) mysql>
11.修改密碼：
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '新密碼';
12.設置權限
為了可以遠程連接該數據庫，需要設置相應的權限
#任何主機 mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '剛剛修改的密碼' WITH GRANT OPTION; #指定主機 mysql>GRANT ALL PRIVILEGES ON *.* TO 'xxxx'@’xx.xx.xx.xx’ IDENTIFIED BY 'xxxx' WITH GRANT OPTION;
13.刷新權限
mysql>flush privileges;
這就完成了，可以用sql工具連接mysql了
