我使用的連結 http://repo.mysql.com//mysql57-community-release-el7-8.noarch.rpm
2. 使用wget 獲取rpm包
[[email protected]_0_10_centos ~]# wget http://repo.mysql.com//mysql57-community-release-el7-8.noarch.rpm --2018-10-05 18:54:49-- http://repo.mysql.com//mysql57-community-release-el7-8.noarch.rpm Resolving repo.mysql.com (repo.mysql.com)... 23.2.3.81 Connecting to repo.mysql.com (repo.mysql.com)|23.2.3.81|:80... connected.

3. 安裝 mysql community-release

5. 安裝 mysql 伺服器
[[email protected]_0_10_centos ~]# yum -y install mysql-community-server.x86_64
Loaded plugins: fastestmirror, langpacks

Complete!
6. 啟動MySQL伺服器
[[email protected]_0_10_centos ~]# systemctl start mysqld.service官方指導 7版本 啟動伺服器有區別
檢查MySQL伺服器的狀態
[[email protected]_0_10_centos ~]# systemctl status mysqld.service
● mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

顯示為 Active: active (running) since Fri 2018-10-05 19:08:06 CST; 52s ago 代表正常啟動
官方提示
7. 檢視初始化密碼
從MySQL 5.7開始 mysql會自動初始化一個密碼 使用者第一次登入 可在錯誤日誌裡檢視
使用一下命令檢視
[[email protected]_0_10_centos ~]# grep 'temporary password' /var/log/mysqld.log
2018-10-05T11:07:57.372256Z 1 [Note] A temporary password is generated for [email protected]: :vqDKto/r1Vr
:vqDKto/r1Vr這是我的初始化密碼（[email protected]: 後面）
8.使用初始化密碼進入資料庫
[[email protected]_0_10_centos ~]# mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 5.7.23
Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> 9.修改密碼
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '簡單密碼';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '複雜密碼';
Query OK, 0 rows affected (0.00 sec)
密碼過於簡單會修改失敗
你以為 已經安好了麼 那你可以遠端連線一下試試看
使用遠端連結會出現 1130 錯誤 （解決如下）
這是因為mysql 資料庫 只對localhost 開啟訪問
10. 切換使用mysql資料庫
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
+--------------------+
4 rows in set (0.00 sec)
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
檢視的user 表如下
mysql> select u.Host, u.User from user u;
+-----------+---------------+
| Host | User |
+-----------+---------------+
| localhost | mysql.session |
| localhost | mysql.sys |
| localhost | root |
+-----------+---------------+
3 rows in set (0.00 sec)
可以看到root使用者只對localhost開放
11. 修改root 使用者對應的Host 為 % （把localhost 修改為 %）
mysql> update user u set u.Host = '%' where u.User = 'root';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
12.退出mysql重啟 mysql服務即可完成安裝
mysql> exit
Bye
[[email protected]_0_10_centos ~]# systemctl restart mysqld.service
[[email protected]_0_10_centos ~]#
安裝完成
End~
