CentOS7安裝Mysql8.0.20步驟：

https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-20.html

官網(wǎng)下載有時(shí)速度比較慢，直接點(diǎn)擊鏈接也可以下載：mysql 8.0.20

官網(wǎng)下載8.0.20Mysql包（bundle版本）

1.創(chuàng)建mysql文件夾：

[root@localhost ~]# mkdir /usr/local/mysql
[root@localhost ~]# cd /usr/local/mysql/

將下載的mysql包放在創(chuàng)建的MySQL文件夾內(nèi)：

[root@localhost mysql]# ll

-rw-r--r--. 1 root root 834560000 5月 13 10:44 mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar

mysql的安裝版MD5碼查看是否和官網(wǎng)上的相對(duì)應(yīng)：

[root@localhost mysql]# md5sum mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar 
c8d062c1f74d9aab7dbdd5300b202b6e mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar

將mysql的包解壓得到幾個(gè)內(nèi)安裝包：

[root@localhost mysql]# tar -xvf mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar 
mysql-community-libs-8.0.20-1.el7.x86_64.rpm

編輯一下/etc/my.cnf文件：
在最下面增加一行：

lower_case_table_names=1

initialize初始化：

[root@localhost mysql]# mysqld --initialize
[root@localhost mysql]#

更改一下權(quán)限：

[root@localhost mysql]# chown -R mysql:mysql /var/lib/mysql
[root@localhost mysql]# ll /var/lib/

啟動(dòng)mysql服務(wù)看一下服務(wù)狀態(tài)，看Active這一行的狀態(tài)：

[root@localhost mysql]# systemctl start mysqld.service 
[root@localhost mysql]# systemctl status mysqld.service 
● mysqld.service - MySQL Server

查看數(shù)據(jù)庫(kù)初始的密碼：

[root@localhost mysql]# cat /var/log/mysqld.log | grep password

[Server] A temporary password is generated for root@localhost: n_t#tk.Z?7)f

使用初始密碼登陸數(shù)據(jù)庫(kù)：后更改密碼：

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

到此可以正常登陸數(shù)據(jù)庫(kù)了，可以自行查找開啟遠(yuǎn)程方式。
