1.mysql服務沒有啟動

打開myql時出現異常，由于mysql服務沒有啟動

mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

2.啟動mysql報錯

啟動mysql和Windows及Ubuntu稍有不同，sodu service mysql start不存在

sodu service mysql start
sudo: service: command not found

查看下mysql的路徑

where mysql
/usr/local/bin/mysql

進到相關目錄下可以看到mysql.server

mysql.server start
Starting MySQL
. SUCCESS!

ok mysql啟動成功
