登陆数据库报错socket错误
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2) 首先检查是否安装了mysql-server了 sudo apt-get install mysql-server to install mysql on ubuntu 如果mysql-server已经存在了那么在去尝试一下是否成功如果还是这个错误的话那么就是文件/var/run/mysqld/mysqld.sock 不存在。 如果/var/run/mysqld/mysqld.sock文件不存在应该怎么办 执行 vim /etc/mysql/my.cnf 将会看到内容如下
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - /etc/mysql/my.cnf to set global options,
# - ~/.my.cnf to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
#
# * IMPORTANT: Additional settings that can override those from this file!
# The files must end with .cnf, otherwise theyll be ignored.

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/你的mysql的配置在/etc/mysql/mysql.conf.d目录下的mysqld.cnf文件打开如下 可以看到:bind-address 127.0.0.1 socket /var/run/mysqld/mysqld.sock 等信息
我的虚拟机是/var/run下面没有mysqld目录执行下面命令然后目录和sock文件就都有了
sudo mkdir -p /var/run/mysqld
sudo chown mysql /var/run/mysqld/
sudo service mysql restart
