1.點(diǎn)擊mysql5.7下載
2.安裝完成后：（記住最后一步分配的初始密碼）
3.啟動(dòng)：可以在偏好設(shè)置中start/stop笛坦，亦可通過(guò)命令
????sudo /usr/local/mysql/support-files/mysql.server start
? ? sudo /usr/local/mysql/support-files/mysql.server stop
? ? sudo /usr/local/mysql/support-files/mysql.server restart
4.簡(jiǎn)化啟動(dòng)命令：
? ?A. touch .bash_profile
? ? B.在打開(kāi)的profile中添加以下內(nèi)容
? ??alias mysqlstart="sudo /usr/local/mysql/support-files/mysql.server start"
????alias mysqlstop="sudo /usr/local/mysql/support-files/mysql.server stop"
? ??alias mysqlrestart="sudo /usr/local/mysql/support-files/mysql.server restart"
? ? C.source .bash_profile
? ? D.通過(guò) mysqlstart啟動(dòng) ?????mysqlstop停止????mysqlrestart 重啟
5.如果忘記初始分配密碼扼菠，請(qǐng)執(zhí)行以下操作
sudo /usr/local/mysql/support-files/mysql.server stop
cd /usr/local/mysql/bin/
sudo su
?./mysqld_safe --skip-grant-tables &
到此mysql的狀態(tài)應(yīng)該是running
?./mysql
FLUSH PRIVILEGES;
SET PASSWORD FOR?'root'@'localhost'?= PASSWORD('新密碼');?
