Debian (Jessie 8.0) mysql can't connect to local mysql server through socket '/var/run/mysqld/mysqld

刚装好的debian8  jessie, apt-get了mysql-server后, 发现没启起来.

root@debian:~# systemctl status mysql.service

提示是守护进程没起来导致的

解决就很简单了, 把守护进程重启下

#/usr/bin/mysqld_safe &

再重启下mysql 就好了

#systemctl restart mysql.service

如果还是启动不起来. 检查下配置文件. /etc/mysql/my.cnf 是不是有错误.

尤其是bind-address, 因为bind后, 启动的时候会去检查这个. 但是却不会给出明显的地址错误
