CentOS 7.4 64位安装配置MySQL8.0

最近新买了一台云服务器,需要安装MySQL8.0数据库,百度了几个教程,发现大都有所缺漏,于是自己摸索着安装,亲测成功。最后将安装过程记录下来分享给大家。


第一步:获取mysql YUM源

进入mysql官网获取RPM包下载地址
https://dev.mysql.com/downloads/repo/yum/

点击下载

获取到下载链接:
https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm


第二步:下载和安装mysql源

  • 进入mysql文件夹,没有的自行创建
[root@VM_0_10_centos /]# cd /usr/local/mysql/
[root@VM_0_10_centos mysql]#
  • 下载源安装包
[root@VM_0_10_centos mysql]# wget https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm
--2018-08-04 10:29:39--  https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm

-rw-r--r-- 1 root root 25820 Apr 18 13:24 mysql80-community-release-el7-1.noarch.rpm
[root@VM_0_10_centos mysql]#
  • 安装mysql源
[root@VM_0_10_centos mysql]# yum -y localinstall mysql80-community-release-el7-1.noarch.rpm

第三步:在线安装MySQL

[root@VM_0_10_centos mysql]# yum -y install mysql-community-server

下载东西比较多,等几分钟。

第四步:启动Mysql服务

[root@VM_0_10_centos mysql]# systemctl start mysqld

第五步:设置开机启动

[root@VM_0_10_centos mysql]# systemctl enable mysqld
[root@VM_0_10_centos mysql]# systemctl daemon-reload

第六步:修改root本地登录密码

mysql安装完成之后,在/var/log/mysqld.log文件中给root生成了一个临时的默认密码。用grep命令搜一下

[root@VM_0_10_centos mysql]# grep "A temporary password is generated for root@localhost" /var/log/mysqld.log 
2018-08-02T02:19:55.829527Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: !J:KUwU9y0ZR
2018-08-02T04:49:34.979689Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: pw</s9,Wivm2
2018-08-04T02:40:46.781768Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: nNyK,Y)Wd0-G
[root@VM_0_10_centos mysql]#

这里有三条搜索结果,因为我重复装了3次MySQL,如果第一次安装是只会有一条的。
直接拿到临时默认密码 : nNyK,Y)Wd0-G

  • 登录MySQL
[root@VM_0_10_centos mysql]# mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.0.12

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

mysql> 
  • 更改root账户临时密码
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Pwd123@easyoh.net';
Query OK, 0 rows affected (0.03 sec)

mysql>

Pwd123@easyoh.net 请替换成你自己的密码。
(备注 mysql8.0默认密码策略要求密码必须是大小写字母数字特殊字母的组合,至少8位)

第七步:创建新用户、授权、远程登录(不要直接使用root账户登录)

  • 创建easyoh-mp用户并且授权远程登录
mysql> CREATE USER 'easyoh-mp'@'%' IDENTIFIED BY 'Pwd123@easyoh.net';
Query OK, 0 rows affected (0.04 sec)

mysql> GRANT ALL ON *.* TO 'easyoh-mp'@'%';
Query OK, 0 rows affected (0.03 sec)

mysql> 
  • 在sqlyog客户端用easyoh-mp账户登录(其他客户端也可以,随意)
image.png

发现会报plugin caching_sha2_password错误。这是因为MySQL8.0密码策略默认为caching_sha2_password。与5.7有所不同。

  • 进入MySQL数据库查询user表信息
mysql> use mysql;
Database changed
mysql> select user,host,plugin from user;
+------------------+-----------+-----------------------+
| user             | host      | plugin                |
+------------------+-----------+-----------------------+
| easyoh-mp        | %         | caching_sha2_password |
| mysql.infoschema | localhost | caching_sha2_password |
| mysql.session    | localhost | caching_sha2_password |
| mysql.sys        | localhost | caching_sha2_password |
| root             | localhost | caching_sha2_password |
+------------------+-----------+-----------------------+
5 rows in set (0.00 sec)

mysql>

发现确实是caching_sha2_password

  • 依次执行下面语句
mysql> ALTER USER 'easyoh-mp'@'%' IDENTIFIED BY 'Pwd123@easyoh.net' PASSWORD EXPIRE NEVER; 
Query OK, 0 rows affected (0.04 sec)

mysql> ALTER USER 'easyoh-mp'@'%' IDENTIFIED WITH mysql_native_password BY 'Pwd123@easyoh.net'; 
Query OK, 0 rows affected (0.05 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
mysql> 

再次登录就可以登录成功了。

第8步:编码

mysql> show variables like '%character%';
+--------------------------+--------------------------------+
| Variable_name            | Value                          |
+--------------------------+--------------------------------+
| character_set_client     | utf8mb4                        |
| character_set_connection | utf8mb4                        |
| character_set_database   | utf8mb4                        |
| character_set_filesystem | binary                         |
| character_set_results    | utf8mb4                        |
| character_set_server     | utf8mb4                        |
| character_set_system     | utf8                           |
| character_sets_dir       | /usr/share/mysql-8.0/charsets/ |
+--------------------------+--------------------------------+
8 rows in set (0.01 sec)
mysql> 

MySQL8.0默认就是utf8mb4编码,无需更改。
OK 至此 Mysql安装配置完毕;
