Can't connect to local MySQL server through socket '/opt/lampp/var/mysql/mysql.sock'

ERROR 2002 (HY000): Can‘t connect to local mysql server through socket ‘/opt/lampp/var/mysql/mysql.sock‘ (2)

 

 

 

原因：系统盘满了

[[email protected] opt]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
18G 17G 0 100% /
tmpfs 504M 0 504M 0% /dev/shm
/dev/sda1 477M 80M 372M 18% /boot
[[email protected] opt]#

解决：

删除大文件后，重启系统解决

 

 

[[email protected] mysql]# /opt/lampp/lampp status
Version: XAMPP for Linux 1.8.3-3
Apache is not running.
MySQL is not running.
ProFTPD is running.

出现的问题：
如果xampp中的mysql启动不了，出现ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/opt/lampp/var/mysql/mysql.sock‘ (2)报错，
停止xampp的时候报：
-bash-4.1# /opt/lampp/lampp stop
Stopping XAMPP for Linux 1.8.2-6...
XAMPP: Stopping Apache...ok.
XAMPP: Stopping MySQL...ok.
XAMPP: Stopping ProFTPD...kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
fail.

解决办法：
如果网上一些方法不好用的话，可以试试以下方法：
1. 确定系统盘是否满了
#df -h
2. 删除/opt/lampp目录中的pid文件（删掉后xampp重启时会重建，如果不放心，可以先备份lampp目录）
删除mysql相关缓存：
#rm -rf /opt/lampp/var/mysql/VM_*  
删除proftp相关缓存：
#rm -rf /opt/lampp/var/proftpd.pid
如果找不到pid文件，可以搜一下：
#find /opt/lampp -name ‘*.pid‘
