...

建立使用者和資料夾

useradd mysql passwd mysql su mysql wget mkdir /data && cd /data tar -zxvf mysql-8.0.23-el7-x86_64.tar.gz mv mysql-8.0.23-el7-x86_64 mysql_3306 cp -r mysql_3306 mysql_3307 su root chown -r mysql:mysql /data/mysql_3306/ /data/mysql_3307/ su mysql

初始化，記錄密碼

cd /data/mysql_3306

./bin/mysqld --defaults-file=/data/mysql_3306/my.cnf --initialize --console --user=mysql

執行

cd /data/mysql_3306

./bin/mysqld_safe --defaults-file=./my.cnf &

連線mysql

./bin/mysql --socket=./mysql.sock -uroot -p # 輸入初始密碼

修改密碼

alter user root@localhost identified by 「root」;

啟動指令碼

vim mysql_start.sh

./bin/mysqld_safe --defaults-file=./my.cnf &

關閉指令碼

vim mysql_shutdown.sh

./bin/mysqladmin -uroot -p123456 -s /data/mysql_3306/mysql.sock shutdown

#遠端設定

mysql> use mysql;
mysql> update user set host=
'%' where user=
'root'
;mysql> grant all privileges on *.* to 'root'@'%'with grant option;
mysql> flush privileges;

連線

cd /data/mysql_3306

./bin/mysql --socket=./mysql.sock -uroot -p

修改賬戶密碼加密規則並更新使用者密碼

alter user 『root』@』%』 identified by 『password』 password expire never; #修改加密規則

alter user 『root』@』%』 identified with mysql_native_password by 『password』; #更新一下使用者的密碼

重新整理許可權並重置密碼

flush privileges; #重新整理許可權
