#安裝與更新

1.安裝

Fedora 28/27/26
dnf install mysql-community-server
CentOS 7.5/6.10 and Red Hat (RHEL) 7.5/6.10
yum install mysql-community-server

2.安裝MySQL 5.7.23

Fedora 28/27/26

dnf --disablerepo=mysql80-community --enablerepo=mysql57-community install mysql-community-server

CentOS 7.5/6.10 and Red Hat (RHEL) 7.5/6.10

yum --disablerepo=mysql80-community --enablerepo=mysql57-community install mysql-community-server

3. 開啟MySQL server 並設定開機自啟動

Fedora 28/27/26  CentOS 7.5   Red Hat (RHEL) 7.5

systemctl start mysqld.service

use restart after update

systemctl enable mysqld.service

CentOS 6.10 and Red Hat (RHEL) 6.10

/etc/init.d/mysql start

use restart after update

OR

##

service mysql start   ## use restart after updatechkconfig --levels 235 mysqld on

4. 取得初始的隨機密碼

grep 'A temporary password is generated for root@localhost' /var/log/mysqld.log |tail -1

Example Output:

2018-11-20T21:11:44.229891Z 1 [Note] A temporary password is generated for root@localhost: -et)QoL4MLid

And root password is: -et)QoL4MLid

#5.重設密碼

alter user root@localhost identified by '自定义密码';
新密码必须大小学数字特殊符号全部具备。

6. 連線本機mysql伺服器

mysql -u root -p OR ## mysql -h localhost -u root -p
