Mysql配置

service mysqld start

mysql -u root -p    #輸入命令回車進入，出現輸入密碼提示直接回車

6.設置mysql密碼：

mysql> set password for root@localhost = password('123456'); ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement mysql> flush privileges; #更新權限 Query OK, 0 rows affected (0.00 sec) mysql> set password for root@localhost = password('123456');  Query OK, 0 rows affected, 1 warning (0.00 sec) mysql>flush privileges; #更新權限 mysql>quit; #退出 service mysqld stop # 停止mysql服務, 恢復mysql配置 vim /etc/my.cnf #修改配置文件 # Disabling symbolic-links is recommended to prevent assorted security risks # skip-grant-tables # 注釋掉這句話 symbolic-links=0 service mysqld start # 啟動mysql服務 mysql -uroot -p # 輸入新密碼登錄
